I have been trying to calibrate steps per unit using mach 3 settings and checking with digital readout.  Not consistent.  It will be off. 018 going in positive direction and. 786 in negative direction.

Got readout installed last night. Hoping to check cnc accuracy and get it calibrated tonight

Hopefully with the scales I can tell it to travel 14 inches and know how far it actually moved within. 0002

I am going to order a digital readout for the mill. Hoping that will help me get steps per unit calculated

Thanks. I've been asked to do lots of small parts I've been turning down. May have to break down and get a small lathe and put a dro on my machine until I can get the cnc accurate

Yeah. But you already knew you could make enough money and get enough work to live on?

Not 100% sure. Today I zeroed over a dot I have in the center of my material. I let it run an engraving program with z raised up. When it returned to zero at the end of the program ( which had many direction changes ) it was off to the left and down over. 500 each way. Going to use dial indicator tomorrow

I was able to get movement before I came to work. The tuning looked good but was too weak to push servos I guess. I went in and raised all the numbers and got the graph looking ok again. Still not travelling correct distance at 20000 and 22222.222. Getting a little discouraged but going to fight with it again tomorrow

If u pull hair out, does it grow back? I retuned my servos.  I believe them to now be correct. But now im getting zero motion from mach3.
