Hello, thank you very much for the videos you posted on TH-cam..I'm from São Paulo Brazil, I set up a plasma cnc but when I clicked to start cutting the plate my computer crashes due to interfering
Hello. Sorry for my English. I wanted to make floating Z axis from 3D printed but the file on the your link to the Thingiverse does not open (error 404). Could you send me this file? Thanks in advance.
Hi, I love your plasma cutter. I have built a MPCNC, with RAMPS 1.4 and Marlin firmware. I wanted to ask you, what programming do you use to make it do the down and then up motion before it starts cutting. I have used this one: M106 g4 s0.7 M107 but I have not been successful :(
I've cut 1/8" with it at 25ipm. The limit is in the HF plasma cutter. The specs say it should cut 3/16" but I haven't tried it yet. The machine will go much faster than what the HF cutter can cut. Would be nice to get a Hypertherm some day but the cost is too much right now.
So how did you implement the floating axis? I just build a table myself, with a floating Z-axis for the IHS. But I haven't the foggiest idea on how to tell cnc to sense the height before each cut. Hope you could help me with that. (The "probe-in" signal is connected and responding in the hal meter)
@@MakingStuff Could you elaborate more I am very interested in building one of these and cannot use an ohmic probe because of my water table, I have the Proma sd that intercepts the signals from mach
Thank you for the videos. I quite enjoyed your build. I do have one question though. I'm looking into building my own amd I have found that there are plasma cutters listed as CNC compatible, yet they don't say what makes them CNC compatible. Do you know what makes a plasma cutter CNC compatible and how to tell if a plasma cutter is CNC compatible? From what I have researched, you can fry your electronics if it's not.
it's late, but the answer is that the CNC compatible ones don't have high-frequency arc start, which could interfere with the electronics. they use another technique called blowback start
Off the top of my head you might be able to implement it in the gcode. Before each pierce home z with G28 Z, then rezero z with a known offset like G92 Z##.###
Nice build. How do you determine the end heigt vs. the microswitch hight?(how does it know the hight after it backs off? ) I See that you have less "waste" travel on this build
Read the whole page.. it is still unclear to me how the floating height is set? Have you measured the height from torch nearly touching and to activation of the switch and put this dimension into the macro or code. Or is it more some sort of probe/contact between torch and material, and then the switch is only to tell that it is detecting?
If you load the .ini and .hal files in the Proma download into LinuxCNC it will create a bunch of new fields on the right side of the screen. One of those fields is called switch height.
Mine have not meted. They have actually held up quite well. The heat stays at the torch tip, not up where the clamps are located. If something ever did happen to them, I can always just 3D print replacements.
Hello what's up? I am from Argentina and I want to download the files to print it but it gives me a 404 error, could you pass the link to me. your projects are very good
It is a bug on Thingiverse.com when you try to download zip file. I've been told by other viewers if you download the files individually, one at a time, it will work.
No. It touches off before each cut. The reason for this is that the metal can bend from the heat which will cause the Z-axis zero point to change as the cuts are made. This will ensure that each cut starts at the same height. The THC will change the height of the torch as it moves across the metal to keep the torch the same distance from the metal while it is moving.
@@MakingStuff The springs in this assortment is tiny and does not contain the ones needed for this. How is this holding up to the heat of cutting for you long-term?
Users have posted in the comments on Thingiverse that the individual file downloads still work. Only the download all button is broken. I tried this and was able to download all the files individually.
How accurate are the holes made by the plasma cutter? Or are you better off making a separate CNC drill to run along the back side of the gantry for drilling starter holes and or larger holes? I guess then that the problem becomes one of rigidity within the system. Any thoughts on the matter, anyone?
I haven't measured any holes for accuracy yet. I have basically been making stuff that the accuracy is not that important. Now that it is working I can start dialing it in.
@@TheRainHarvester any controller you want. I want to use the planet cnc controller. I say when you build the tool path you plasma the holes under sized by 1/16 inch or so then ho back with hand drill or drill press to clean and make to size
@@mastermoarman I hope you have a large tool budget. You'll be going thru a lot of chewed up drills due to the surface hardening of the plasma. Dial it in!
Clever little design, Mr. Stuff.
Thanks!
Nice one, loved the build , would love to make one also. Thanks for pointing us to the files used.
Hola, ¿como conectas el micro switch ? ¿En la placa o en el enchufe que va a la PC y lo manejas con el Mach 3?
Muchas gracias
I never thought you could cut metal with a plastic cnc and harbor freight torch!! I'm always fixing hf stuff-lol, even made a video a couple days ago!
How are the printed parts holding up long term?
Great idea thanks for the video! Have fun!
Hello, thank you very much for the videos you posted on TH-cam..I'm from São Paulo Brazil, I set up a plasma cnc but when I clicked to start cutting the plate my computer crashes due to interfering
sir, I want to ask how to install the limit switch
thank you for wanting to explain
Awesome addition to your setup. Does this mean you don't need the other switch
nice update
but we cannot see the news results in comparison to the old
Just what i loking for days, thankyou, you have a New sub
Thanks for the sub!
Awesome. Glad it worked well. Thanks for the credit :)
Thanks for sharing it. It saved me from have to make one from scratch.
Good build series, thanks for the effort.
Thank You.

I am currently using PlasmaC configuration of LinuxCNC.
What's the thickest steel you've cut and at what speed? You should do more videos of the cutter. Nice work.
I've cut 1/8" with it at 25ipm. The limit is in the HF plasma cutter. The specs say it should cut 3/16" but I haven't tried it yet. The machine will go much faster than what the HF cutter can cut. Would be nice to get a Hypertherm some day but the cost is too much right now.

It was built in to the code that came from Proma for the THC.

Sure it's possible. Thanks for watching!

@@MOUNIROU60 Thanks for the reply.
I see LinuxCnc was used, but is there some way to use grbl (with the height/touch-off functionality)?

Show, belo trabalho, amigo, tem como informar o esquema de relé do gatilho.
What port do you connect the limit switch to?
Nice build. How do you determine the end heigt vs. the microswitch hight?(how does it know the hight after it backs off? ) I See that you have less "waste" travel on this build
There is a switch height setting in configuration I downloaded from the Proma web site.

Ottimo lavoro dove posso acquistare questo asse mobile
We have done this 3d printed clamps but it will melt on a production cnc plasma machine !
Mine have not meted. They have actually held up quite well. The heat stays at the torch tip, not up where the clamps are located. If something ever did happen to them, I can always just 3D print replacements.
Electricity and water! Is that standard practice? I have no clue about plasma.
Yes. The water is there to cool off the slag after its removed from the metal. Helps keep the smoke down
Hello what's up? I am from Argentina and I want to download the files to print it but it gives me a 404 error, could you pass the link to me. your projects are very good
It is a bug on Thingiverse.com when you try to download zip file. I've been told by other viewers if you download the files individually, one at a time, it will work.
Think you would be better off using a Plasma machine torch, more clamping length and greater stability.
Do you need that limit switch?
hey can you post any video where you share the thc connection to the interface?
It's just 3 pins. Up, Down and Arc OK.
so is this floating axis taking the place of the THC?
No. It touches off before each cut. The reason for this is that the metal can bend from the heat which will cause the Z-axis zero point to change as the cuts are made. This will ensure that each cut starts at the same height. The THC will change the height of the torch as it moves across the metal to keep the torch the same distance from the metal while it is moving.
Good one!
Do you have the files for 3d printed torch holder? Is your torch 30mm? The one on thingiverse only have the 26mm
Did you leave me a message on Patreon?
Yes I got it thanks
Will that setup cut 1/4" steel?
Yes it will. The only limit is the cheap Harbor Freight plasma cutter. It only goes up to 40A but will cut 1/4inch steel if I slow it down a bit.
¿Que filamento usaste? What filament did you use?

Yep you could have tighten the drawer slid up by touching it in the vice..Makes it rigid..

Hello Friend! Where did you get the springs? did you make them on a lathe or there's a place to get them?
A spring assortment pack like this one. amzn.to/2tiBOhe
@@MakingStuff The springs in this assortment is tiny and does not contain the ones needed for this.
How is this holding up to the heat of cutting for you long-term?
@@patooyeeIt's still good as new. No parts have melted or broke.
I can't get the file off Thingiverse anymore! gives me a 404 error. Do you still have the files?
Users have posted in the comments on Thingiverse that the individual file downloads still work. Only the download all button is broken. I tried this and was able to download all the files individually.
Ok thanks for your response, I will give that a try. Do you still run this setup?
Hi. Does the system work on grbl ?
No it uses g-code.
@@MakingStuff thx
What 3d printer did you use to make the part? What type of wire did you use?
Creality CR10S. Everything was printed with PLA.
what post processor did you use for sheetcam
I got it from one of the users in the LinuxCNC forum.
hi thanks for sharing this
Thanks for visiting
Don't you have any interference? If no then how did you dealt with it..?
Nope, shielded wiring.
I'm using a cut 60 brand Saints, friend can you help me with information to end the interference
can you resolve the problem with interference?
Hello my friend! I managed to solve the problem of my machine, today it is working fine, your videos are very good. what is your city?
How accurate are the holes made by the plasma cutter?

If you need really accurate holes. You can set the program to undercut the hole and drill them by hand to size
MasterMoparMan what controller? Grbl?

The plastic does not melt?
Nope.
