My Newb Plasma Table Attempted Build

No, the part shows as it should be. Also I swapped drivers, and can't home...I get following errors. Swapped them back around and now I can't do anything. More following errors when trying to home. Sometimes one axis will make it through, then another will have the error. I'm about sick of this.

Gonna end this thread here. I'm just going to tear it down and get rid of the belt drive, the laptop, etc etc and do a big do-over now. I should've never taken in those jobs at the time I took them. This really blows my mind.

Swapping drives should have no effect on the software

Did you just unplug the step/dir and motor connectors from the
drives and swap drives?

I powered down everything and swapped the plugs (both plugs per each driver). Even after I put them back - they're labeled - it was giving errors.

What the h.......
Did you try to do a round shape, not from the wizard, use inkscape, draw a circle, path>object to path, extensions>gcodetools>path to gcode, open in LinuxCNC.

No, I don't have Inkscape. I'm getting a regular PC and starting over with that. I only need the G.D. thing to cut my plates for rack and pinion and then it can go all the way to hell.

Can you try this, it is in MM and has G21 in it so it should work as is, feed set at 10inch/m

I can't. It won't even home now.

Edit: just gives following errors. And not on the same axis each time. Maybe my laptop got a virus.

You could widen the following error limits, but this is just a work-around for host PC latency issues.

I suspect your laptop does not have the good real time performance the LinuxCNC requires.

You may be able to work around this by

1. Setting the servo thread time to 2 mS (2000000)
2. Widening the following error limits to say 0.005, .02

I'm already with ya on that, in a way. Picking up a proper PC for the task tomorrow. The servo thread time is already at 2000000.
