Now...example...x-axis instead of reading +8.00 for and 8" plate at the 8" mark...Now reads +200 at 8 inches.....SMH

Could it be because of different units?

The CNC3040 Was Running at 400 steps...Shut down...went back to do more testing....was engraving "Small"...My Table Size according to the Mach3 Software became astronomical in size.....Had to increase my steps from 400 to 10,000....does not make any sense to me,,,,Now when I run it...its sounds "musical"

Hi Bill,

I think it is as Craig has already said (400*25=10,000) you have your Imperial and Metric units confused.

Put you steps back to 400 and put a G20 into the beginning of your Gcode. Then it will be in Inch Units and the correct size instead of Millimeter Units and way too small.

Should I just un-install everything and start from scratch....I re-set everything...This is just running the table...Not Sending Codes....Size of Table off the charts again....Set it to run 8" and it moves about 1/4 inch....I out it back to 10000, 300, 300 for x and y and 4000, 150, 300 for Z and it runs 8" and read 8"....Will it hurt anything to have the settings like that....I run it at 30% speed

Hi,
you could un-install and then re-install but I suspect that you'll end up in the same situation. You need to set your machine up in 'native' units
of your choice and then use G20/G21 to set the units for any given G code job. You should not, after the initial set up, of the machine ever have to
touch the motor tuning pages. That you are suggests confusion over units.

Config/Select Native Units should be set to your preference and thereafter left alone. The Steps per Unit setting on the motor tuning page is the
pulses required by the driver to move the controlled point one unit. You can either calculate it or measure it but it won't change unless you change
the gearing of an axis or microstepping of a driver. Likewise the Homing/Limits page is in native units.

Only when a job comes along which is drafted in different units do you use G20/G21.
