Mach3 screens
« on: July 29, 2009, 05:59:38 PM »
Hi there,
Are there any posts regarding description of screen diaolgue boxes?What does  go to variable or set variable mean ? also what is the code in the upper right hand corner of screen used for. Next I am having trouble getting my cnc to move the correct distance . I am using mm's if I enter x10 the axis will move maybe 150mm.
here is my calculations maybe I have got it wrong, my lead screw has a pitch of 1.75 mm I am using 1/4 microstep setting.
200x4 = 800 /1.75=457.142. steps per mm           revs per mm 1/1.75= .5714revs.
Thanks

Your calcs seem correct for step per unit, not sure what you are needing revs per mm for?
 If zero the X DRO then command a G0X10 does it still move 150mm?

Your steps per unit for the Y are set to 900457.142
You have Y++ set to Port1 Pin 3, you cant have that because pin 3 is an Output.

Thanks Hood,
I don't know how the settings above changed I always have them the same while I have been trying things, I would never set Y to 9000odd, maybe the key board keys got accidently pressed, also know to set to pin 10.
let you know how things work out , I think i wil start from scratch and make a new profile
regards
Bernie
