Hi. Sorry, my mistake. I meant 100 mm per minute, not seconds. And up to 3000 mm/min which I think it is 100+ ipm. It works ok with this speed. Anything higher shakes the gantry when it stops.
Only the z axis has a belt 2:1 ratio system, X and Y are direct drive.
I still have the 800 pulse/rev setting. I.ve only tried 1600 and 2000, and they worked fine, when they worked.
In motor turning I had (as the pc does not work anymore), the STEPS PER set by the the test done in Settings Alt6 tab.
ˇˇIn settings tab, I typed I want to move it 50, and it did move 150, and mach 3 set it to 160 steps for X and Y axis. The driver setting is at 800ˇˇ
VELOCITY 3000 and ACCELERATION 200.
