I have been working on a Plasma/Router table for awhile now. Primarily for Plasma, I have built it from left over steel, powder coating the frame. It is a rack and pinion with one drive for the Y Axis. I have used Chinese steppers with TB6600 drivers. I have a dedicated Windows XP PC for this and my Shoptask. Using Mach 3, I have started with Sheetcam. I have an older Lincoln ProCut25 that I have wired in with a Proma THC. I am still working out bugs, but Les from Sheetcam has been more than helpful overcoming issues that arose from the Procuts safetys. All my cables are shielded and well grounded, but I am having issues with the movement stalling right after firing the torch. I am open to suggestions. I am going to try increasing stall time between firing and movement and also changing acceleration tuning on the motors. Again, any ideas would be appreciated. I will try to upload pics in the near future.
