General Mach Discussion / problem settings -need help
« on: February 04, 2013, 06:01:53 AM »
hi,
i am new to mach and i am trying to setup a mill system.i have smooth stepper and pmdx 126 board.
i need help for basic settup. here is my thoughts:
i have steppers with 200 steps/rev
i set microstepping to 16 so i will have total 200*16=3200 steps per rev OK?
the ballscrew pitch is 5mm per rev so should i input 3200/5=640 steps per unit at the motors setup?
1)what microstepping should i use for a mill bf20 machine (g0604 equivalent)
i have problems with the jog stepping too. for example if i set the jog step to 0.01 i do not see 0.01 steps at the dro when i jog i see 0.0104 -> 0. 0208 -> 0.0299 ...
2) what is going on?units are in mm
3)i set the max speed at the 600 at the motor setup screen . why my max speed is at 72units/min at the feed screen ?
4)limits :
is the mach3 moves all the axis simultaneusly when homming or is it homes one axis at a time? i am trying to find out how many limit switches i need. yes the x-- and home x , y-- and home y, z++ and home z share the same switch so finaly i will need 3+3=6 switches?
i what inputs? input pins are the 10-13 and 15. the 10 is reserved for estop.
11 > x-- and home x
12 > y-- and home y
13 > z++ and home z
is it ok if i use the inputs for the seccond port of the SS for the x++,y++ and z-- ?
thanks
i apreciate any help
