I don't really know how to go about finding out my screw pitch. I clamped my caliper and sent the table 200 pulses (one motor revolution) and measured 0.155-0.160in travel which would be 6.25TPI which sounds weird so I tried metric. 4mm/rev so 0.25TPMM? the screw diameter is 0.330in(3/8?) or 8.38mm
About the only screws online I can find with a similar size is 3/8-32.
EDIT:
I was re-watching the mach3 vids and found the troubleshooting one then found the axis calibrate one... no need for any math my axis is now accurate. Then all of a sudden my DRO is in mm and gcode is read in inches. How the heck to I get the DRO back to inches?
