Thank you, Rich!
I will continue to investigate.

General Mach Discussion / Re: Steps per unit difference

« on: January 04, 2017, 03:30:17 AM »

I read the manual, I followed these steps and in settings section (Alt-6) everything is allrightr. The machine moves accurately. But in Program Run, when I load a g-code file with a simple square, the y- axis is wrong. I will insist and test it several times, and then restart the program.

Another thing: the guys from stepcraft advised me to buy Uccnc and motion controller for the best results. Mach 3 is not so suitable for stepcraft. What do you think?

Thank you so much. I am a beginner, but I love to learn.

Sorin.

General Mach Discussion / Steps per unit difference

Confused and frustrated

Stepcraft 420 with mach3

I read on here that ideal steps per Unit in motor tuning is 133.333333.

I tested this on a 8cm square profile job. Result: x-axis= 8 cm, but the y-axis=8.7.

I went then to the section settings where there are steps per unit set button to help you test how each axis moves per unit.
x and z are okay, but moving y double than its command.
Mach 3 suggests automatically adjust it and we have the half of steps per unit for the y-axis, so 66.6.

I then tested and found my square with x = 8, y = 4.4

What happens?
