Here at work we have an old, 1996, plasma and torch combo. We bought another plasma table around 2004 and quit using this one, only using the torch on occasional jobs over 1 inch mild steel.
For the past 4 or 5 years we only used this machine as an “auto” aluminum annealer so you dont have to stand there with a torch.
About a year ago the controller went up in smoke, well I want to make this hunk of metal move again.
I dont need any plasma or torch control, I just need to be able to move the torch head around.
Im not sure if the servo motors on this thing are any good and I dont want to use them.
Even as dirty as this thing is right now, with the rack and pinion disengaged it rolls really easy and smooth.
I dont need it to move very fast, 20mm/s is plenty and it wont have any extra load being put on it.
So Im wondering if a Nema 17 or if need be a 23 would move this thing. Pushing it feels like no more force needed than to push my lowrider.
Would the 33.9:1 reducer work?
If the reducer is fine then it will be just a matter of mounting the stepper where the servo is now and making the pulley on it fit on the stepper.
Firmware is something I have no idea about, Ive flashed it, Ive ran PID tunes and entered them and stuff but Im not sure where to start with this.
