Help withController dip switch settings and Mach3 motor tuning
I have 3 m542 steppers, 33v power supply and the following three steppers for my x,y,z axis; Vexta steppesr:
X= PK 296-02AA (2 Phase 1.8° step, DC, 3A)
Y: PK268-03A (2 Phase 1.8° step, DC, 3A)
Z: PK268-03A (2 Phase 1.8° step, DC, 3A)
and a 5 axis breakout board like this one Attachment 10760
What setting on the DIP switches should I be setting Attachment 10759
Also what setting should I be setting in Mach3 in the motor tuning section.
The travel of the x axis is 80mm per revolution of the x stepper motor if this is required for setting calculations.
Thanks in advance for any help or advice. More info on my DIY build/retrofitting can be found here http://www.mycncuk.com/forums/diy-cn...html#post51435
Re: Help withController dip switch settings and Mach3 motor tuning
I'm not an expert in this but for a start I would use these settings.
sw1 - ON
sw2 - ON
sw3 - OFF
sw4 - ON
sw5 - ON
sw6 - ON
sw7 - OFF
sw8 - ON
In Mach3 put the "steps per" at 20
keep the acceleration and velocity low for now.

I wouldn't use Eddy's settings. (Sorry Eddy no offence)
Motors are 3A so go to nearest lowest not higher. . .So 2.8A going higher can lead to hot motors.
sw1-off
sw2-off
sw3-on
Currant mode is for when motors are at stand still so set to Half current mode and they won't get red hot.
sw4-off
Micro stepping will depend on few factors like PC speed and parallel port speed etc so I'd start lower first. So 800 Micro steps.(1/4 stepping)
sw5-on
sw6-off
sw7-on
sw8-on
If your parallel port can stand the strain then having higher micro stepping gives smoother running motors and lessens chance for resonance.
Are you sure it's 80mm per revolution.? That's a large pitch and low resolution.!! . . . . If correct then use 10 in Steps per in Mach. (80mm/800Ms=10steps per/mm)
