I am almost there. I’m having a problem with Z resolution. I’m still plotting stuff, haven’t installed my spindle yet.
I am using Ramps 1.4, , 5/16 allthread Z screw, Ryan’s MPCNC813 Firmware, controlling with Repetier.
I found a .dxf of a Harley Sign I’m trying to plot. I loaded the .dxf into Estlcam, scaled it to about 200 mm wide, and saved the gcode.
When I run the plot, using a sharpie in the pen holder with the bushing and screw, the Z axis is lifting between plot segments, but each time it puts the pen down, it puts it down farther each time until the sharpie is squeeking or pushed up out of the holder. I think this is due to the Z axis resolution being too high.
Looking at the firmware settings in Repetier, I see that X axis resolution is 100 steps/mm, Y axis resolution is 100 steps/mm, and Z axix resolution is 2650 steps/mm. Is this correct?
