Thank you for the kind words. We have gotten quite a few questions on limit switches and general GRBL firmware issues. We are hoping that this will help many through the process.
@@lightburnsoftware7189guys, your commitment made me buy the license before trial expired. I feel safer getting Lightburn than i feel about getting Adobe product.
Brilliant video. I ordered the parts from Amazon UK except the T-nuts that they couldn't supply in the correct size (thank you Ebay). Fitted the switches to my S9 with no problem. Wired in with an extension on the x axis and fired it up. Checked the position, setup the macro and pressed the home button. Got an error message telling me to move the y axis switch by 1.5mm. Nudged it up the channel a little and did it all again. Perfect!!!! Turned the laser and computer off, turned it all back on again and put $$ in the console. New values are still in the machine - seems they are using some type of flash memory now, the firmware doesn't need to be changed each time. Still have the macro just in case. Thank you guys, don't know how I lived without the limit switches before. This process was so straight forward and I learnt a lot about GRBL at the same time. Now playing with print and cut - another good video and even better written instructions.
Thank you for the feedback and great to hear you are up and running with limit switches. It really makes a huge difference and is required for specific modes/features.
This was exactly what I was looking for! I got my first laser engraver last week, and AtomStack A5 Pro and found out real quick that not having limit switches was going to make my experience even more challenging and it's a hard enough learning curve. As mentioned in the video that different brands models may have to be done a bit differently and that was the case with mine for the Y axis as there's not anything to hit the switch. I made a small bracket attached to the inside of the top front wheel bolt using aluminum angle to hit the switch and it has finally found it's way home thanks to you guys!!!
I followed this video and the next one to update the GRBL software on a Atomstack A5 and it worked perfectly. The only hitch was in loading the GRBL firmware in the Arduino IDE but following advice in the comments to .zip the relevent folder all worked perfectly. Great video and thanks for making.
Awesome, glad to hear. Speed is a bit of personal preference and the axis direction will be unique to each laser depending on the pinout and wiring of the steppers.
WOW! This is the best video on how to install limit switches on Sculpfun machines, the supplied China videos with the links they supply tell you to watch outdated TH-cam video, download outdated software and tell you to burn it to your new 32bit mobo which could result in making it useless. This is by far a much better way of doing it. It also resolved a big issue we see new people seem to always encounter with the limit switches/printer working in reverse. Awesome video, very informative. Good Job ;).
This is exactly what i was waiting for! I had limit switches installed and all i got the machine to do is complain i have to type $X to unlock movement
Thank you very much, Your tutorial brought the fun back to my sculpfun 😊. It was the negative coordinates that blew my mind 🤬. Unfortunately, this is not mentioned by the manufacturer.
@@assantemark Hi Marx what problem did you find with the Atomstack was it that you could not fit the limit switch to the left hand side y axis, I found that the carriage misses the limit switch so I’m thinking I may have to mount it on the right hand rail y axis cheers Matt
If I understand correctly, there are only two limit switches for the homing position (left and front). What about the other two sides of the machine: right and end positions? Is it possible to mount two other end stops there, or are motherboards of diode laser engravers limited to two switches only?
There are ways to wire it so either of a pair of switches will trigger the limit stop, but it’s not really needed. Once the machine is homed, as long as it doesn’t lose position the firmware won’t allow it to go out of bounds - soft limits enforce this, and LightBurn will warn if you try to send something outside the usable area too.
Received my Sculpfun S9 this week and ran through your setup (very easy, thanks!!). It did save the settings without updating the firmware. Maybe they're shipping with a better version now?
I was a little uncomfortable with leaving the circuit boards exposed like that, so I tweaked your .stl file to make an enclosure for the limit switch, which I'll be happy to send to you, if you'd like to use it or include it for others.
We had originally designed a different .stl for the 3d printable option but decided we wanted to keep the same file for the printable and laser cut option. If you have not already, uploading it to a .stl sharing site would be great to give others an alternative option.
What version of lightburn were you using in this video? I don't know what lightburn or sculpfun have done, but I installed my limit switches and followed your coding and it worked perfectly but before I created a macro, I copied the coding and decided to test it before actually creating the macro, I turned off my laser and closed down lightburn and then started lightburn back up, switched on my laser and pressed the home key and the laser moved to the home position without creating the macro. Can you throw any light on this please? 1.3.01 is my copy of lightburn.
@@rklauco - Homing is done wherever the machine is configured to do it. There are physical switches in the machine that are pressed when it homes and the location of those switches dictates which corner it needs to go to. LightBurn just tells it “go home” and the machine does everything else.

2 wire limit switches work just the same, but no LEDs to show when the switches are triggered (5V to light the LEDS is not used). Increase homing pull pull off (set $27=2).
Hi again, Making progress. 2 issues i am having. Issue 1 is when i hit the home but it moves only so far in the correct direction so i have to hit the home button until laser is homed, Issue 2 is that when it hits the limit switches and the lights come on it backs off so far that the lights go off and then it surges ahead to rehome itself and stays on the limit switch with no back off and the lights stay lit. I have the atomstack 5r pro My hard and soft limits in machine settings are set to false if that matters. If i forgot to give any info Please just ask me for it. I am new to this laser business so be patient with me Thank you in advance for any replies.
Did this one atomstack a5 pro . everything worked fine. Then installed drag chains and lengthen the wires. In the process I may have plugged the limit switch wires in backwards. Now the x and y axis move but no fan on the laser module or laser operation. So I have to ask what damages if you put them in backwards? I know the limit switches aren't shot I have two new ones. I have a new controller card coming it should be here in a couple days but not sure if I've damaged the laser or the card or both
If you used the same limit switches that have LEDs you may have sent 5v back to the board. I would lean more towards it being the controller than the laser module. It sounds like you are starting with that which is what I would have done as well.
@@lightburnsoftware7189 so after about a week of banging my head against the wall. Getting absolutely no help from Adam stack. I tried a new board maker MK sdlc version 2.1 with the same results laser wouldn't work. After one last option I went and retrace my wiring I extended for the laser head turns out I actually mixed up to the wires and thankfully didn't hurt the laser or the fan or the board or anything.! So I'm using the new makerbase card just because. But thankfully I didn't hurt anyting but that didn't stop me from upgrading my lazerhead the new one will be here soon I will be upgrading to a laser tree 4 LDS version 2. Should be a heck of a laser when I'm done Adam stack thoroughly disappointed me with their customer service glad to be rid of everything except the frame. The old lazerhead all use on my homemade CNC with the original board that I didn't need to replace LOL!
I've just purchased the limit switches but realise that I also extended my frame to the 950mm one. will any of the values you said about be different to this? Thank you for a great tuturial.
Values (should) remain the same. Enabling switches, setting the homing direction, and possibly adjusting homing speeds. The main thing will be needing longer wires for the x axis.
@@lightburnsoftware7189 Thank you for your reply. Would you have a link of where I can purchase the extension cables please, as I'd like the correct ones for my laser. Once again thank you.
I put the switches at the bottom right on sculpfun s9 I modified using glbr and laserburn and now it does the home at the bottom right, but if I start it it slams against the switch Y as if it were upside down, I tried to engrave manually and it results on the contrary (but not mirrored) how can I do??? Thank you
Is there a reason you went with bottom right over bottom left? GRBL expects bottom left to be 0,0 so using another corner is likely going to require an offset macro. You can read more under the CNC section here: docs.lightburnsoftware.com/CommonGrblSetups.html#getting-machine-settings The options will be an offset in console that you can turn into a macro (This will have to be entered each time the machine turns on) or swapping limit switches to bottom left.
Have been looking but can't seem to find the answer. What is the benefit of adding limit switches. Aren't print and cut and circle finder already usable without them?
I, too, am wondering what the benefit of the limit switches is. If you park the laser head at the zero/zero position before you power up the unit Lightburn will consider this the home point for the entire session. Works perfectly for me. (Sculpfun S9)
The atomstack a5 has the controller at a different location; am I correct to say that the Y Axis switch is to be placed at the left front (0.0 mm) position even though the controller box is located at the back left of the machine instead of the right front like the Scuplfin is?
What a brilliant support video!! I bought a Sculpfun S10 and went through the process of purchasing the items to fit the Limit Switches. I VERY carefully installed the wiring; checking and triple checking my G (Black), V (Red), S (Green) wires were correct. When I reconnected the USB and Power switch and turned it on, Lightburn wouldn’t recognise any connection. I noticed that the USB light on the motherboard was off. I disconnected the X and Y connectors from the motherboard and the USB light came on and I was able to connect my S10. Does anyone have an idea what might have gone wrong? Thanks. Bill.
@@codreanurazvan5928 I've seen that somewhere else and wondered if it might fix it. I was a bit wary of messing up the motherboard, but I'll give it a try when I get back at the end of the month! Thanks.
@@codreanurazvan5928 Thank you for the advice! Had the same problem and fixed it like that! :D In my sculpfun S10 the wiring was the following (green in the top, black and red cutted out)
I installed the limit switches on my Sculpfun s9 the the locations you have them I plugged in the machine pressed home it went in the right direction right away but it hits the limit switch light come on but it doesn’t stop there it crashes into them and freaks out and try’s to keep pushing past them I have to turn the machine off. I tried it a few times even checking the wires we snug and everything is all good it just won’t stop when the limit switch light comes on.
HELP Please! I just extended my Y axis on my S10 and I set up the new travel distance to be 910mm. But regardless of what I do, the homing stops halfway on the Y axis. I see a message in the Lightburn console that says that the limit switch was not found in the specified distance so the travel is stopped. Where do I find and change the distance in the GRBL code?
The Y axis extension instructions should mention this - you need to change the $131 setting in the firmware of the laser itself. github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration#130-131-132--xyz-max-travel-mm
Hi, using an Atomstack A5 Pro. I installed the switches but when I go to home I get the following error: ALARM:8 Homing fail. Cycle failed to clear limit switch when pulling off. Try increasing pull-off setting or check wiring. ok Grbl 1.1h ['$' for help] [MSG:Check limits] [MSG:'$H'|'$X' to unlock] [MSG:Caution: Unlocked] ok Any idea what I'm doing wrong?
Hi I got the chance to play around with an Atomstack. Now I am thinking about getting diode a laser in 10W or 20W. What I have been wondering is if 2 limit switches is enough, wouldn't 4 be better and can they even be installed on an S9 or something similar? Yet I couldn't find an answer to that. Also does anyone know if the limit switch, Z height and linear rail modifications also work on the longer ray diode lasers?
Since the max work area size can be set in GRBL firmware and in LightBurn there is no need for max limit switches. Most have the auto home toggle on startup checked so it auto homes to the min limit switches each time the machine connects to LightBurn. This ensures it will not run out of bounds. In some cases you can force it out of bounds but the work of configuring additional switches both physically and on the firmware side is probably more work than its worth. For the additional modifications we have not tested them. Most diodes do not have a Z that is motor driven.
Added the same limit switches to my S9 and with both plugged into the board, Lightburn will not connect to the laser, though it will if only the X axis is plugged in OR the Y axis plugged in, if both are connected, I get 'Waiting for connection' in the console window. The board I have on mine is the DLC32 v1.0. All wiring correct, plugs aligned correctly
That is really odd. I was going to suggest something may be shorting but if they both will work on their won then there is no reason they shouldn't be working when both plugged in together. This is the first time I have heard of this. If you have not please contact support@lightburnsoftware.com images of the switches/wiring will be helpful.
@@lightburnsoftware7189 One of the issues with not connecting might be the thickness of the wooden raisers. I made mine out of 1.6mm thick, and the contacts of the limit switches protruded and made contact with the aluminum rail. Solution was to trim down the contacts on the bottom side of the PCB with the snipping tool, or to use thicker wood. Hope this helps.
When you click on the drive link you should see a button in the top right corner that is 3 dots stacked on each other. Click on that and then download. When it does download it will be a .lbrn2 project file that you can import into LightBurn.
We do not do reviews since we are brand agnostic but we did cover a video on how to get the D1 working with LightBurn as well as how to use their rotary with LightBurn.
Thanks found the file the atom stack is not as easy to put the limit switch on y axis left hand side as you cannot fix in position as the carriage misses the switch, may have to mount on right hand side anyhoo see how it goes
Did you try mounting the switch on the vertical face of the extrusion instead? The carriage will engage it when I do it that way. Or you could cut a few modified stops to build up a mounting block which allows you to place the switch in upside down (therefore engaging on the right where the carriage frame will indeed strike the arm)…?
Hey, if this is being monitored anymore, I am trying to put some limit switches on a different machine-when I hook up the limit switches, the usb port on the control board starts to smoke because it is pulling power from my computer-any idea why that might be happening?
thanks. :) I'll give that a try-not holding my breath though, but then that's what I get for buying a cheap laser engraver. Lots of DIY. At least if I blow it up, it didn't cost me too much! Seriously though, I really appreciate a reply at all, much less on a weekend. I am amazed you guys are still monitoring this video, given its a year old.@@lightburnsoftware7189
I installed my switches, easy enough to do. But for some reason when I press the home button, it moves in the right direction then stops after moving towards the physical home position. Once stopped there it will not do it again. IF I move the laser back or to the side. press home it goes to that spot again. Like it has determined that this location is home.
You can use either. The 3 wire version typically comes with a PCB and is easier to mount and wire with the included JST connection. If you go with a bare limit switch you will usually need to solder the wires and it would require a different mount.
The first video (limit switches) was excellent and everything worked. This one has not worked for me. First, the “library” you are providing is NOT an Arduino library. I have tried old and new versions of Arduino IDE and all say it is invalid. Can you please check the download file? I’m surprised to hear some people saying it worked for them.
Got a weird one for you. Limit switches added. wired properly. I do $$ all settings GRBL factory normal. $21=0 BUT I get a error: 5, Homing cycle not enabled in GRBL settings. I run macro called Limit Switches. All settings go to what macro says as per this video. Primarily $21 to 1 and NO errors. Now EVERY time I press Home, I get error: 5, Homing cycle not enabled in GRBL settings but $$ shows $21=1. Also setting the G10 L2 P1 is there or is there not a space between the 3 inputs?
OLA, GOSTO MUITO DO LIGHTBUNG SÓ ESTOU COM UM PROBLEMINHA... QUANDO ACIONO O CICLO DE HOME ($22). ACIONA MAS DA SEMPRE ''AGUARDANDO CONEXAO'... E 'BUSY' ME AJUDE A CONECTAR CORRETANTE
I added the switches and it goes home great. the only problem I have is now I can only jog laser in one direction in Y and one in x direction. I try to frame and it goes to the opposite diagonal corner in rear. I only have setup with the macro so I power down and restart without macro and it works fine but I can’t home. What did I do wrong?
Did you select the correct corner for origin? If not that would cause things to be mirrored and could cause movement to behave as described if the laser thinks it is at max distance in one direction. Also, I would try absolute coordinates for the Start From mode.
@@lightburnsoftware7189 Thank you for your time. The error I get says value on or near line five is not recognized. I will try this again and use your suggestion. Thank you.
I got them to work because I didn’t have the right numbers for -409. and -399. Numbers.The question I have now is when laser is done cutting it stops and goes home but it crashes moving on the diagonal, Moving in the regular homing x then y it works fine. I really appreciate your time.
If the laser is disconnecting when the switch is triggered I would check your wiring. If you are using similar style endstops and the 5v line is mixed up the laser could be shutting down to protect itself from damage.
Since the X axis runs from left to right and both sides of the tram travel together, there is no reason to mount the limit switch on the farthest point from the board... the right side is just fine.
In the case of this machine as long as the sides are mirrored and it will be triggered on either side location wont matter for Y. For X you would want the switch on the left side to match what the GRBL firmware will set it to. You can apply a workspace offset if you do want the switch and laser to home to a different corner but it is an added step.
my laser is homing as it should but when it goes the right side its bangining into the frame and making funny noises , i have set $130 and $131 to lower settings but it still doing it , HELP
You would need to make sure the board has spots available for limit switches. You also would want to check that the mounting points on this do not need to be altered for your machine.
Did you follow our video on setting up the S30? I would verify you have origin set correctly. th-cam.com/video/pf3lN7pxWYo/w-d-xo.htmlsi=_x2l1NmhCz-qlfld When you try to home does it home towards the limit switches and just not trigger? If you follow the video guide and are still having problem contact our support team - support@lightburnsoftware.com
Anyone know how to install this on a Longer RAY5 10w engraver? I have the limit switches and all but all the ports are not free. looks like theyre occupied by the flame alarm or something.
@@lightburnsoftware7189 I actually got help in tje end sp it's working as I want it know. It's very handy to have limit switches to pick up a job if something went wrong or so ^^
We have not specifically tested on the S6. I would first look at the board to see what controller is in the machine and if it has spare ports for limit switches.
We have not tested the S10 specifically, but in theory other than possibly homing direction (this will depend on the wiring of the steppers) everything else should be the same. You will want to enable homing, and hard limits, choose auto home on startup, and make sure it homes the correct direction.
I'm kinda scratching my head on my problem. My Machine will not move when I send the $22=1. It is not a popular brand but the board is Makerbase MKS 2.1 V. I'm thinking maybe just go to the flashing board video.
In theory as long as it is running GRBL, and has the connections for limit switches on the board then yes. However, we have not tested it on the S10 and you will need to be careful when wiring to make sure the pinout is correct.
You can route the wires differently if preferred and there are other limit switch styles. We chose these due to their common form factor and that they come with enough wire that you do not need to do any splicing\crimping.
The folks at LightBurn are to be commended for such a video by going beyond their normal scope of support.

Values (should) remain the same. Enabling switches, setting the homing direction, and possibly adjusting homing speeds. The main thing will be needing longer wires for the x axis.
@@lightburnsoftware7189 Thank you for your reply. Would you have a link of where I can purchase the extension cables please, as I'd like the correct ones for my laser. Once again thank you.
I put the switches at the bottom right on sculpfun s9 I modified using glbr and laserburn and now it does the home at the bottom right, but if I start it it slams against the switch Y as if it were upside down, I tried to engrave manually and it results on the contrary (but not mirrored) how can I do??? Thank you
Is there a reason you went with bottom right over bottom left? GRBL expects bottom left to be 0,0 so using another corner is likely going to require an offset macro.
You can read more under the CNC section here:
docs.lightburnsoftware.com/CommonGrblSetups.html#getting-machine-settings
The options will be an offset in console that you can turn into a macro (This will have to be entered each time the machine turns on) or swapping limit switches to bottom left.
Can you recommend for TTS-55 please, it works with the same components?
Guess I will be doing this in the next few days!
Have been looking but can't seem to find the answer. What is the benefit of adding limit switches. Aren't print and cut and circle finder already usable without them?
I, too, am wondering what the benefit of the limit switches is. If you park the laser head at the zero/zero position before you power up the unit Lightburn will consider this the home point for the entire session. Works perfectly for me. (Sculpfun S9)
@@howardsmaid3491 I'll post this question in the lightburn forum.
The atomstack a5 has the controller at a different location; am I correct to say that the Y Axis switch is to be placed at the left front (0.0 mm) position even though the controller box is located at the back left of the machine instead of the right front like the Scuplfin is?
What a brilliant support video!! I bought a Sculpfun S10 and went through the process of purchasing the items to fit the Limit Switches. I VERY carefully installed the wiring; checking and triple checking my G (Black), V (Red), S (Green) wires were correct. When I reconnected the USB and Power switch and turned it on, Lightburn wouldn’t recognise any connection. I noticed that the USB light on the motherboard was off. I disconnected the X and Y connectors from the motherboard and the USB light came on and I was able to connect my S10. Does anyone have an idea what might have gone wrong? Thanks. Bill.
cut the NC pin on the microswitch.
@@codreanurazvan5928 I've seen that somewhere else and wondered if it might fix it. I was a bit wary of messing up the motherboard, but I'll give it a try when I get back at the end of the month! Thanks.
@@billswindlehurst293 I already had same issue and fix it like that
@@codreanurazvan5928 Thank you for the advice! Had the same problem and fixed it like that! :D
In my sculpfun S10 the wiring was the following (green in the top, black and red cutted out)
Hi can you do a vid for adding limit switches to the Xtool D1 I'm sure it would be very popular? Cheers great vid.
I installed the limit switches on my Sculpfun s9 the the locations you have them I plugged in the machine pressed home it went in the right direction right away but it hits the limit switch light come on but it doesn’t stop there it crashes into them and freaks out and try’s to keep pushing past them I have to turn the machine off. I tried it a few times even checking the wires we snug and everything is all good it just won’t stop when the limit switch light comes on.
HELP Please!
I just extended my Y axis on my S10 and I set up the new travel distance to be 910mm.
But regardless of what I do, the homing stops halfway on the Y axis. I see a message in the Lightburn console that says that the limit switch was not found in the specified distance so the travel is stopped.
Where do I find and change the distance in the GRBL code?
The Y axis extension instructions should mention this - you need to change the $131 setting in the firmware of the laser itself.
github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration#130-131-132--xyz-max-travel-mm
hey i´m having a problem, the s9 keeps saying that is busy on lightburn, and cant proceed any longer
Are these compatible with the Sculpfun s6 pro?
Hi, using an Atomstack A5 Pro. I installed the switches but when I go to home I get the following error:
ALARM:8
Homing fail. Cycle failed to clear limit switch when pulling off. Try increasing pull-off setting or check wiring.
ok

Any idea what I'm doing wrong?
Hi
I got the chance to play around with an Atomstack. Now I am thinking about getting diode a laser in 10W or 20W.
What I have been wondering is if 2 limit switches is enough, wouldn't 4 be better and can they even be installed on an S9 or something similar?
Yet I couldn't find an answer to that.
Also does anyone know if the limit switch, Z height and linear rail modifications also work on the longer ray diode lasers?
Since the max work area size can be set in GRBL firmware and in LightBurn there is no need for max limit switches. Most have the auto home toggle on startup checked so it auto homes to the min limit switches each time the machine connects to LightBurn. This ensures it will not run out of bounds.
In some cases you can force it out of bounds but the work of configuring additional switches both physically and on the firmware side is probably more work than its worth.
For the additional modifications we have not tested them. Most diodes do not have a Z that is motor driven.
Added the same limit switches to my S9 and with both plugged into the board, Lightburn will not connect to the laser, though it will if only the X axis is plugged in OR the Y axis plugged in, if both are connected, I get 'Waiting for connection' in the console window. The board I have on mine is the DLC32 v1.0. All wiring correct, plugs aligned correctly
That is really odd. I was going to suggest something may be shorting but if they both will work on their won then there is no reason they shouldn't be working when both plugged in together. This is the first time I have heard of this. If you have not please contact support@lightburnsoftware.com images of the switches/wiring will be helpful.
@@lightburnsoftware7189 One of the issues with not connecting might be the thickness of the wooden raisers. I made mine out of 1.6mm thick, and the contacts of the limit switches protruded and made contact with the aluminum rail. Solution was to trim down the contacts on the bottom side of the PCB with the snipping tool, or to use thicker wood. Hope this helps.
Great video, ordered my parts today, Spacer file is in code not sure hoe to get that into lightburn any help is greatly appreciated
When you click on the drive link you should see a button in the top right corner that is 3 dots stacked on each other. Click on that and then download. When it does download it will be a .lbrn2 project file that you can import into LightBurn.
Have you ever done a review on tge xtool d1? I was thinking about getting one...
We do not do reviews since we are brand agnostic but we did cover a video on how to get the D1 working with LightBurn as well as how to use their rotary with LightBurn.
Thanks found the file the atom stack is not as easy to put the limit switch on y axis left hand side as you cannot fix in position as the carriage misses the switch, may have to mount on right hand side anyhoo see how it goes
Did you try mounting the switch on the vertical face of the extrusion instead? The carriage will engage it when I do it that way. Or you could cut a few modified stops to build up a mounting block which allows you to place the switch in upside down (therefore engaging on the right where the carriage frame will indeed strike the arm)…?
Hey, if this is being monitored anymore, I am trying to put some limit switches on a different machine-when I hook up the limit switches, the usb port on the control board starts to smoke because it is pulling power from my computer-any idea why that might be happening?
That would be something you’d need to ask whoever made your machine - wiring is going to be board specific.
thanks. :) I'll give that a try-not holding my breath though, but then that's what I get for buying a cheap laser engraver. Lots of DIY. At least if I blow it up, it didn't cost me too much! Seriously though, I really appreciate a reply at all, much less on a weekend. I am amazed you guys are still monitoring this video, given its a year old.@@lightburnsoftware7189
I installed my switches, easy enough to do. But for some reason when I press the home button, it moves in the right direction then stops after moving towards the physical home position. Once stopped there it will not do it again. IF I move the laser back or to the side. press home it goes to that spot again. Like it has determined that this location is home.
what is the difference in 2 core limit switch cable and 3 core as i have 2 core. will it affect the efficiency of the machine?
You can use either. The 3 wire version typically comes with a PCB and is easier to mount and wire with the included JST connection. If you go with a bare limit switch you will usually need to solder the wires and it would require a different mount.
The first video (limit switches) was excellent and everything worked. This one has not worked for me. First, the “library” you are providing is NOT an Arduino library. I have tried old and new versions of Arduino IDE and all say it is invalid. Can you please check the download file? I’m surprised to hear some people saying it worked for them.
Got a weird one for you. Limit switches added. wired properly. I do $$ all settings GRBL factory normal. $21=0 BUT I get a error: 5, Homing cycle not enabled in GRBL settings. I run macro called Limit Switches. All settings go to what macro says as per this video. Primarily $21 to 1 and NO errors. Now EVERY time I press Home, I get error: 5, Homing cycle not enabled in GRBL settings but $$ shows $21=1. Also setting the G10 L2 P1 is there or is there not a space between the 3 inputs?
Also when I disconnect the 2 limit switches my Sculpfun 8 Pro works great.
Just got it to work. Had to change $22 from 0 to 1 also. Homing cycle, boolean
OLA, GOSTO MUITO DO LIGHTBUNG SÓ ESTOU COM UM PROBLEMINHA... QUANDO ACIONO O CICLO DE HOME ($22). ACIONA MAS DA SEMPRE ''AGUARDANDO CONEXAO'... E 'BUSY' ME AJUDE A CONECTAR CORRETANTE
I added the switches and it goes home great. the only problem I have is now I can only jog laser in one direction in Y and one in x direction. I try to frame and it goes to the opposite diagonal corner in rear. I only have setup with the macro so I power down and restart without macro and it works fine but I can’t home. What did I do wrong?
Did you select the correct corner for origin? If not that would cause things to be mirrored and could cause movement to behave as described if the laser thinks it is at max distance in one direction. Also, I would try absolute coordinates for the Start From mode.
@@lightburnsoftware7189 Thank you for your time. The error I get says value on or near line five is not recognized. I will try this again and use your suggestion. Thank you.
I got them to work because I didn’t have the right numbers for -409. and -399. Numbers.The question I have now is when laser is done cutting it stops and goes home but it crashes moving on the diagonal, Moving in the regular homing x then y it works fine. I really appreciate your time.
This just doesn't work for me. Whenever the laser hits the limit switch the Laser USB just disconnects.
Any idea what might be causing this?
If the laser is disconnecting when the switch is triggered I would check your wiring. If you are using similar style endstops and the 5v line is mixed up the laser could be shutting down to protect itself from damage.
Can this work on the XTOOL D1???
Since the X axis runs from left to right and both sides of the tram travel together, there is no reason to mount the limit switch on the farthest point from the board... the right side is just fine.
In the case of this machine as long as the sides are mirrored and it will be triggered on either side location wont matter for Y. For X you would want the switch on the left side to match what the GRBL firmware will set it to. You can apply a workspace offset if you do want the switch and laser to home to a different corner but it is an added step.
May I ask how long the extension cable should be?
The ones we recommend in the description are 70cm. However, there is a bit of extra slack on them.
@@lightburnsoftware7189 I purchased and received all the parts you suggested, I am about to install the limit switch tomorrow 😁
my laser is homing as it should but when it goes the right side its bangining into the frame and making funny noises , i have set $130 and $131 to lower settings but it still doing it , HELP
If it is homing the way it should at what point is it banging into the right side? Are your limit switches in the bottom left corner?
Can these items be used on an AtomStack A5 Pro?
You would need to make sure the board has spots available for limit switches. You also would want to check that the mounting points on this do not need to be altered for your machine.
I added limit switches according to this video, and now my Atomstack will not work with them plugged in.
Will this limit switch hack work on the xTool D1 ?
I need help to fix my laser s30 pro , it is not homing , it is not finding the limits twitch please help
Did you follow our video on setting up the S30? I would verify you have origin set correctly.
th-cam.com/video/pf3lN7pxWYo/w-d-xo.htmlsi=_x2l1NmhCz-qlfld
When you try to home does it home towards the limit switches and just not trigger? If you follow the video guide and are still having problem contact our support team - support@lightburnsoftware.com
Anyone know how to install this on a Longer RAY5 10w engraver? I have the limit switches and all but all the ports are not free. looks like theyre occupied by the flame alarm or something.
If there are not free ports on that board for limit switches I would reach out to the manufacturer and see what they say before attempting.
@@lightburnsoftware7189 I actually got help in tje end sp it's working as I want it know. It's very handy to have limit switches to pick up a job if something went wrong or so ^^
Will this work on an S6 too?
We have not specifically tested on the S6. I would first look at the board to see what controller is in the machine and if it has spare ports for limit switches.
same parameters of "$" are for S10 as well?
We have not tested the S10 specifically, but in theory other than possibly homing direction (this will depend on the wiring of the steppers) everything else should be the same. You will want to enable homing, and hard limits, choose auto home on startup, and make sure it homes the correct direction.
@@lightburnsoftware7189 yes it working for S10 as well. i tried
I'm kinda scratching my head on my problem. My Machine will not move when I send the $22=1. It is not a popular brand but the board is Makerbase MKS 2.1 V. I'm thinking maybe just go to the flashing board video.
Got to read, read, read and when you are done....Read some more! I got it figured out!
Glad to hear! What did the solution end up being for your board?
She is cookin Now! Applied off set and changed location of Limit switches.
Works on s10 too?
In theory as long as it is running GRBL, and has the connections for limit switches on the board then yes. However, we have not tested it on the S10 and you will need to be careful when wiring to make sure the pinout is correct.
those are not the correct word connectors
Se mira antiestetico ...no me gusta
You can route the wires differently if preferred and there are other limit switch styles. We chose these due to their common form factor and that they come with enough wire that you do not need to do any splicing\crimping.
Man it would be great to not have to use hacky work arounds with the xtool
