i have been reading the manual and looking at the post i just want to see if i have this right i am running a rack and pinion on my plasma table i have a 1" pinion I'm using geckos and 3 to 1 planetary gear heads
I'm not sure but but i have come up with 1910 steps per inch I'm assuming a unit is a inch from other post. not to sound flippin dumb but do i just stick 1910 in the steps per box.(in the motor tuning window) the velocity and acceleration i guess i will mess with once i get this figured out.
I'm running 270oz motors at 24volts (homeshopcnc)will this make Mach run all my code to the right ratio

welp went downstairs to try 1910 and it moved to inches so i cut it in half 955 and of course it went 1 inch wonder how i calculated it wrong with my calculations it still should be 1910 could anyone tell me where im going wrong

Maybe your Geckos are set to 1/2 step mode? I don't have Geckos but I understand there are DIP switches somewhere that set the mode.
You also might want to try using the Axis Calibration feature on the settings page- it works good. After you have your steps per set, then you can mess around with velocity and acceleration till you get max speed without missing steps.

im using the g201 im sorry i forgot to mention that the 10x step driver so you think that if the motor has 2000 steps im pretty much right with the 1910 steps a inch with a 1" pinion and a 3 to 1 gear head
-
I ran the numbers and it looks like 1909.86steps per inch... Are you sure it is a 1" Dia and not Rad :(
-
now this is wierd i ran 1910 in mach 2 and the 1910 works but not mach 3 i must have a setting wrong in mach 3......
update
well i just reloaded mach 3 and turned off my computer for awhile and turned it back on everything seems to be going fine i wanted to thank you so much for taking a look at this with me im very new at this once again thank you
