Title: Homing problem - Slave Axis stopped responding
Post by: Plan_B on March 29, 2015, 10:57:31 PM

Appologies if this is in the wrong forum...


I'm using Ger21's MACH3 2010 Screensets. The problem is with my X Axis, which is driven by 2 motors (one on each side of gantry - so X axis and A axis). A is the slave axis. I have been using the Auto Homing routine provided with the 2010 Screensets for a couple of years without any problems.

However, today... I hit the REF all home button and when it started to home my X Axis, the A motor didn't respond, but the X motor did. I tested it and the A Axis does work with both jogging and using G Code - Just not for Homing... 

I checked the Config settings to make sure that the A Axis is still correctly configured for homing, and it is.

Anyone come across this one before? I haven't changed any settings and it's been working for years...

Please and Thanks!

Hey!

Nevermind, i figured it out :oP
 Here's what the problem was for anyone else that might stumble here with the same issue....
It was just the polarity on the A Axis Home switch... I somehow ended up with the switch polarity toggled for A and not for X. So MACH 3 thought A was already on the switch...

Cheers!
