General Mach Discussion / homing slave axis??

« on: January 07, 2008, 06:51:40 PM »

Hello all,

I am in the process of homing my  machine for the first time!!  I have a 2 motor x-axis using the slave feature.   when I jog this axis   both motors seem to operate as expected. But when I try and home this axis, the salve motor will not respond??   

 Is there a setting in the homing/limits field that needs to be addressed


thanks for any input in advance

General Mach Discussion / setting kernal speeds on Mach 3

« on: December 12, 2007, 05:49:30 PM »

Hello all,

Can someone tell me where to get the kernal speed in mach3 ??    When the system was installed the kernal speed was set to 25k but I would like to change that value.

Also in the motor tuning field I can only set my velocity as high as  412. in /min.   mach will not let me go any faster??  Is there a way to overcome this ??


thanks in advance for any info !!

Hello all,

I am in the process of setting up mach3.  I have set up  all my input and output data and am able to spin all the x,y and z motors using the MDI screen. 

 My issue is with the "motor tuning" screen.  I'm not sure what value to input for the "steps per" field.   The info for my machine is as follows:

-using a 4.29:1 gear reduction
-running the gecko's at full step
- rack and pinion grear is 0.750" DP  on a 20TPI rack

I have calculated 1step = .0027 " per step final drive ( .0750*3.14/4.29/200 )


What value should be entered in the "steps per" field as i am not sure what this unit is asking for !!


thanks for any help in advance !!!!
