- #usbfoamcutter #grbl
Following up on my last video on troubleshooting and questions I said I would see if I could get some later firmware to work the controller program. After some long hours and lots of testing, I am glad to say the "GRBL Hotwire Controller" now works with grbl-Mega-5X firmware.
Plans to build the foam cutter are $3 with a free ebook rckeith.co.uk/downloads/usb-f...
So in this video, I'll show you how to install and configure the updated firmware and software for the USB CNC Foam Cutter.
Here is a list of new features and fixes for GRBL HotWire Mega 5X
- Limit Switches/End-Stops now supported
- G93 Inverse Time mode supported
- Running latest GRBL firmware adapted by Gauthier Brière github.com/fra589
- Connect/Rescan buttons issue fixed on older laptops
- G-code developed in Jedicut now displays correctly
- Bad number format error message has gone.
- GUI has been reworked slightly for CNC foam cutting
Full Details on the website rckeith.co.uk/grbl-hotwire-me...
Since releasing the video I've posted an easy way to install the firmware on the website rckeith.co.uk/easy-way-to-upl...

Thanks for all your work on this. Don
My pleasure!
Just installed limit switches and all worked great
Glad its working for you.
Great work on the gcode sender! Have been working on grbl 5x myself getting the corexy support working.
Wasn't sure I could get it to work but turned out to be not too bad, I learnt a lot more about GRBL doing it.😀
@@rckeith I had thought about using universal gcode sender and making some plugins for it. The 5x fork of grbl is very versatile, unfortunately it has corexy bug that was inherited from the mega fork😕
Nice tutorial really useful! thanks from Argentina
Your welcome 😀
Solved, I managed to do it by xloader, thanks for your videos!
Excellent! Its much easier.😀
YOU'RE A GENIUS! THANK YOU SO MUCH!
Thank you😀
Very nice work wanted to comment early
Thank you.
Great work Keith!!! I´m actually building a V2 of my Foamcutter (belt driven) and yes, i´ll add limit switches :) !
Thanks. Send some pictures be good to see a belt driven version.
@@rckeith hmm... getting some errors when compiling the code ("WCO refresh must be greater than one."
and "Override refresh must be greater than zero."
) - any idea
@jetpilot72 have you got the correct board selected, that can stop compiling.
@@rckeith yes, settings are correct - tried it on a new arduino mega and it worked! Limit switches are working :) thank´s again for your time and help! Is there a way to donate something????
Well done! Kudos!
Thanks😀
Creative video, thanks for sharing :)
Hello there!
Nice job you did on the original software, it is looking really good!
Although I would really appreciate you kept mine and Gerrit Visser's name on the software's credits window.... you know, just for good manners, like I did on the first iteration on Garret's work.
But again, great job and keep it going! Glad to see it's been useful for you and many others.
Cheers!
Hi Daniel, Yes I will put it back. I think I overwrote it by mistake and published it before I noticed. It was a lot of work and I modified many parts and added quite a lot. It's pretty stable now so will only be bug fixes now.
Keith
Thank you this is very helpful
You're welcome!
Thank you !
très bon travail merci
very good job thank you
Thanks, it was a lot of work but enjoyable😀
Thanks sir...from Indonesian
Your welcome.
thanking lot sir good with you
The "homing seek" ($25) Should be a larger value than the "homing feed" ($24). When the homing cycle starts the carriage moves toward the limit switch at the ("seek rate"$25) until the switch is triggered. Then (pull-off $27) is executed. Then the carriage moves toward the limit switch at the ("feed rate"$24). This is executed slowly moving until the switch is triggered giving more accurate and repeatable result. If these values are large "feed" and small "seek" and the carriage is at the other end of the track it will slowly move down the track until it triggers the switch then backup "pull-off" distance and swiftly engage the switch again. taking a long time and giving less than optimum results. If large "seek" and small "feed" are used the carriage will move swiftly down the track engage the switch "pull-off and slowly engage the switch again taking much less time and giving optimum results. Excellent Video I will soon be building this. Thank you
Good afternoon. I have a question. Is it possible to somehow add another rotary axis to the control program and to the firmware. To rotate a part standing vertically on a table?
Hello Keith,
Thanks for all the lovely videos.
Do you think you could make a version of the hotwire controller that works on Linux. Or atleast guide me (and others like me) on how to make one. Thanks
Thanks. I don’t have the skills to do that. There is a version on the website based on Marlin which doesn't require Windows. It just runs off the LCD.
@@rckeith ok. Thanks so much
Hi keith.. Great job. Have seen or used winghelper? . That is what im currently using. Its helpful since i also have a laser cutter..
Hi Victor, no I haven't it does look very good from the video. Have you used it for foam cutting?
@@rckeith yes it works very well....and gcode works with grbl with no issues
Keith, can you point me in the direction of homing and setting stops without switches?
You can only use homing with switches. Make sure $22=0 in settings. That disables homing with switches. So now when you power up that is the zero position for all axes.
hi Keith Howlette, thanks for your work, firmware and control panel work fine, but now I have problems with the drawings that is: if I wanted to cut a normal circle and not a wing, what program should I use to make the x axes recognize , y, z, u? thanks francis from italy
Hi, Francis probably the best is DevFoam 2 www.devcad.com/eng/devfoam2.asp you can also try Jedicut which can use DXF files with a CAD drawing of a circle. I haven't tried that but it should be possible.
Keith
@@rckeith thanks for the availability and the quick response I think you are right now I try and keep you updated if the solution works thanks francis
Quick question: As you mentioned, the axis are xyz and u. What if you have a program for a cut that is written for xyz and a. What is the easy way to change all the A's to U's if there is one? Or do you have to manually do it in Notepad? Thanks again. Don
You can use the Edit->Replace in NotePad with Match Case tickbox selected. That should do it.
@@rckeith Thanks Keith- got to try that. Don
are you still using springs when doing swept wings? does it work?
Yes have a looks here on my video and I show how mines setup th-cam.com/video/yzCKXei0pLU/w-d-xo.html
Thank you for all your demonstration video. But i can't download the GRBL Mega 5x software from your website please help
I think the site was down for a few minutes. Try again if not send a screenshot showing the problem
@@rckeith After wait about 8 hours, I still can't download it.
Good afternoon my friend.
first I would like to thank you for the material so well prepared by the friend.
my problem is as follows:
when I click on the "U" axis the following error message appears: (unsupported command please check your settings)
also in: Limited swtch status it does not enable the status.
the rest seems to be all in order only these problems with the same U axis.
I look forward to your reply.
Sincerely
Adann Cicaczewski
I've replied to your email
@@rckeith Thanks.
we talked by email
great job. But i i have a problem with output of voltage to hot wire its only output same voltage as is ramps powered . i powered ramps with 12 volts hot wire is always 12 volt
Hi Marcin. I have an update coming out soon that should fix that. But in the meantime you can use the Manual Command and set the voltage that way. So to set 6 volts enter M3 S500 or for 12 volts M3 S1000. The range is 0 to 1000. Hope that helps. The updated application should be out in a few weeks with some other minor fixes as well.
Keith
Hey can I make some changes in grbl mega 5x edge to make some functions and pinouts to use that functions like automatic tool change and auto tool measure and workpiece measuring ???
Can I make changes and if I can then what files I have to edit cpu mapping and declaration of pinouts ?
Have a look here github.com/fra589/grbl-Mega-5X/wiki/Pinout-mapping-in-cpu_map.h
Great video, super excited about getting a 5 axis grbl board going. I sent you a msg on your website but this is probably better so everyone can learn. I have a Bigtreetech GEN V1.0 board. I can flash the .HEX file and it runs GRBL but no success using arduino to load the .INO file. I am using an unmodified config.h file. I also tried flashing the arduino code to a HEX file and flashing it. It will load but serial port does not give me a $ sign. What am I doing wrong?
Hi Jeff l replied to your email.
Could you post the fix. " so everyone can learn" ...thanks !
are you using devwing to design your wings and generate your gcode?
I use DevWing Foam 2, I have a full tutorial on the channel.
@@rckeith Thanks Keith. I've watched your videos and think I have the process all put together. I just need to build the foam cutter now.
Hi sir great project. How Can I use the U-Axis as my rotary axis ? I want to use this axis for angular rotation?
You would need to recompile the firmware and define the 4th axis as rotary. Have a look here github.com/fra589/grbl-Mega-5X/blob/edge/grbl/config.h at line 56 where you #define N_AXIS_LINEAR 3 which means the 4th and would be rotary. The foam cutter firmware is based on Gauthier's GRBL Mega 5X with a few alterations. The firmware on my website will only work for 4 Linear axes but compiling the firmware isn't too difficult if you have some 3d printer experience.
Hope that helps
Keith
Ok I’ll try sir thank you
Hello Keith,
Is there a way to change the axis names to X, Y, I and J? Thanks
No there isn't. Change your g-code. The latest firmware and software works with XYZA this changed on the last release which was XYZU
@@rckeith thank you sir
Hi, great job sir,
If the wire length is 2500mm can it work, because I need to cut a eps block with 2500mm legth
I think you would need to use a separate power supply for the hot wire. The MKS board I show in a later video can use 24 Volts and several guys have used over 1000m but I can't be certain on 2500mm. I would perhaps suggest making the part in two sections and that way it would be fine.
Keith
Thank you for your reply, now we are using welding machine for heating the wire and we are cutting manually. But I am not sure that if the wire is 2500mm length then the heat will be uniform in all aria.
Thank you and waiting for your new video.
Sir I solved my all problems by help of you now I am working with my machine
But I am having problem in finding center for my round workpiece
I do probing in square form grbl gru i have grbl mega 5x vmc diy
But I don't know how to probe round workpiece for machining
I don't have any experience probing and I haven't used grblGuru application. You would be better off asking on his site.
When I run the $I command, I'm getting Axis XYZAB, not XYZU. How do I fix this? I'm also getting a #define bit(b) (1UL
You are not using the correct firmware that's the default grbl-mega-5x. Follow the instruction here www.rckeith.co.uk/easy-way-to-upload-cnc-foam-cutter-firmware/
It uses Xloader to upload a pre-compiled hex file. Much simpler if you are new to Arduino
Keith
@@rckeith Thanks Keith. I missed that link. Question. 1) Do I have to remove the ramps board when I load the Xloader? 2) Can I simply 'overwrite' the current version on my Arduino or do I need to set it back to default (which I have no idea on how to do...) Thanks in advance.
@@rckeith Thanks Keith. I followed your procedure above and was able to get all the motors turning today. Now I just need to build the gantries.
Hi. Could I use an MKS Gen L (ramps 1.4 on a single board basically) with this firmware and a 2-axis machine in mind? Only belts, 2 motors and wheels on 2020/2040 profiles.
Thanks
I'm just about to release an updated version of the Windows CNC application which works with the MKS GEN L board. Still have some testing to do but it should be released in a couple of weeks. Not sure how you intend to use 2 axis on it but it will expect 4 axis g-code or there will be an error.
@@rckeith Hmm, that sounds awesome.
However since your program already works with the RAMPS 1.4 I find it curious that the MKS GEN L needs a special treatment. I watched a youtube video where a guy made it work with grbl-mega with no problems ( th-cam.com/video/X2ZULHbKFvE/w-d-xo.html ).
About the two axis thing, I'm trying to build a machine like the Polyshaper Azul, to cut letters with it.
I've already built a Cnc foam cutting machine with grbl+Arduino uno following the How to mechatronics tutorial but it just wasn't rigid enough and I also wanted software hotwire control, something that only a Mega board could give me
@@alejandroperez5368 It's just the windows software. I found on one laptop it woked fine with no changes and then on another it would not send any data back to the interface. I eventually found it was the way the software was initialising the connection. I beleive its to do with the way the USB is implemented different laptops. It now works with the changes I made. You may be OK with the current software but there is a channce it may not work. Version 3.3 out soon with ensure it works.
Keith
@@rckeith I will try it out when possible. However, you mentioned that trying to use 2-axis gcode would throw an error so I no longer know if this program is the right one for my application. As I said earlier, I'm only looking to cut letters and logos with it!
Edit: I forgot to include that I will be generating the gcode with Inkscape's Gcodetool extension.
@@alejandroperez5368 You could just copy the x and y to the u and z and that would work. Quite easy in Excel.
nice job man!! it work for 2 axis? i'm tryng , but, not work
Have a look at the troubleshooting video th-cam.com/video/yzCKXei0pLU/w-d-xo.html it covers common problems with axis not working
@@rckeith nema17 are working, what doesn’t work is the homing cycle, I’m following in their footsteps, I’ve already tried NO and NC, I’m Brazilian and my writing is terrible. lol
@lobo3501 Check on the website rckeith.co.uk/grbl-hotwire-mega-5x-for-cnc-foam-cutters/ under the heading "Homing/Limit Switches Configuration" there is a language translator on the website so that may help. Check your settings are the same. Can you send some pictures of your settings and I will have a look.

No G51 isn't supported in GRBL
@@rckeith suggest me something about alignment the workpiece
i want to get perfect alignment in x and y axis
During operation right now I am unable to hold workpiece again in perfect straight line
I machined and unclamps it and use it or do something else and then after i want to machine it again for some cuts and drills what ever
Then how I align it perfectly it's very challanging for me right to align perfectly again and again after unclampimg and clamping there is giving minor errors in positioning perfectly
Is it any rule or formula or tool for perfect alignment each and everytime clamps and unclamps the workpiece
Hello sir I am having problem in 5th axis
4axis turning 90 degree but
When 5th axis is going to turn the 4th axis gone again zero
I thinks it's some error of my post processors
Sorry I don't have any 5 axis experience try the vendor of the g-code generation software
@@rckeith okay I am using fusion 360 software and they also don't have any idea about it
Has anyone else had the controlling program stop working after about 20 seconds? I have not even gotten a wing code to load and work! Only can move the steppers and half the time it says that a command has not completed! I have loaded the mega using the ino and xloader both! Using the Arduino ide, It loads and the serial monitor reads correctly but I get several pages of red line faults, then it says loaded. Any suggestions? Thanks
Can you send some screenshots and pictures of your setup. Not had anyone with that problem. Could be a hardware issue. Check the troubleshooting video on the channel if you haven't already. It might help diagnose the problem.
Keith
I had to set $20 (soft limits, bool) to 0 in settings tab. Otherwise I could not move any motors past 0 point. Only towards negative numbers and back to 0 worked but no positive numbers were allowed. Program would give brief error message and then froze. I have not set up limit switches (yet).
@@retkimora I've updated the firmware. The download was configured for limit switches. It now set for no limit switches by default. Should fix that issue/
@@rckeith
Keith, I am going back to watch your set up videos. This morning I found the comment. Above about the soft limits. I remember you mentioning this when you went through the settings. I looked to verify I had this set correctly and see that I messed this up. I changed the settings and the motors keep moving with out fault! One miss and I wasted your time trying to help me. I will watch them again and see if I can get this thing going. Thanks for your time and efforts for all of us, and retkimora for coming forward and mentioning this to help me.

How do I configure my machine diy cnc
I am using grblgru software for connecting machine and sending gcodes
For 5 axis i build 5 axis machine
But after connecting it gets homing in right direction in real world but in software grblgru z gose down but my homing of z is upwords
And then i move z down for machining it goes out of the frame in software
Then it goes down and accordingly to z code probing is going to wrong direction
I have used GrblGuru so you would be better asking the developer
@@rckeith My grbl 5 x mega edge is not setup machine
When I press homing it goes home where I decided my setting is $23=0
But when take to center on my workpiece to start the job
I starts probing but it's gose in upwords direction where homing gose but my job is below
How i setup and run my first job in cnc
Did I have to configure machine
My homing settings is upword right corner
But in software it shows right corner but in downward direction it goes below the bed in software
When I upload gcode it goes upwords but in actual machine it has to go downworda to make things worked

I guess I'm too stupid to actually use this program. I can upload my G-Codes, but I cannot set my steps per mm, I cannot set my Feedrate properly (The software does some really weird stuff when I try to alter the feed rate) and it won't give me a preview of what I'm about to cut with a jog position indicating where it currently is. These are the ultmost basic requirements I'd have to use a software for hot wire cutting (2D would be enough for me TBH) but I just can't for the live of me figure out how to configure these feautures.
I'm working with a CNC Hotwire cutter that was modified from using paralell port to accepting USB via GRBL, it doesn't run any arduino intermediate and directly accepts G-Code commands. All I can consistently do is move the wire around using simple commands such as X100 or Y-50. I tried loading up some G-Code, which worked, but it didn't give me any preview and since I don't have any limit switches I won't run any G-Code without knowing where 0 is currently and wether it will fit inside the build space of the machine beforehand.
The old Mach 3 setup had all these feautures, but Windows XP is just way to old and the PC running the software was on it's way out. If it wasn't for that PC I'd still run the old Mach setup. Never change a running system I guess. Now I did change it and feel the pain. I hope I don't have to code my own interface to get this thing to work properly again..
Hi
The preview of the the wire path expects the g-code to be formatted in a certain way. I'm very soon going to release an updated version which will display the preview for all formats of g-code. In the meantime can you set your software that generates your g-code to only use G0 and G1 and not G00 and G01. There also needs to be a space between each instruction for example G1 X5 Y10 U5 Z5 F100.
If you can send your g-code I'll take a look
The feed rate can only be set in the g-code. I still have Mach3 running on Windows XP and its does have many more features than the grbl based solutions. You can get Mach3 to work with USB by using an special adapter. I have a post on the website called 6 solutions for the obsolete Mach3 Parallel Port. May be worth a look.
Hope that helps
I've just released a Beta version of the software you can try. It's on the website in the downloads section. Working on a new video to accompany it which should be out in a very soon.
