Crazies Motors !!!... Please Help!!!
« on: December 19, 2011, 06:33:57 PM »
Extreme Newbie here.  I have a  homemade CNC and it was running fine for a month.
Now, I have a problem with two of my motors (Y and Z axis).   When I specify an UP move
It go UP or DOWN, randomly.  Same if I specify a DOWN move.

I reinstalled the MACH3... but same.

Both Stepper Motors are HT23-280-8 from Robotix.
The third one (X axis) is a HT23-400-8.
All in parallel.
Gecko540.
Mach3.

Would one of you kind souls please enlighten me?.

Thanks.

Frank

Frank, it will be what ever profile you are having the problem with.  It will be a file in your mach 3 folder with the extension .xml
Mach3Mill.xml for example.  You may have to rename it if you can't attach it.  A file with the same name as one that has allready been posted cant be posted again.  To attch it click on the additional options tab at the bottom of your reply window.

That is just a blank xml, you need to attach the one you are using.
Open Mach and at lower right of the main page you will see the profile name, look in the Mach3 folder for a file with that name and a xml extension, you can then copy, rename and attach to the forum.

first thing I would do is check all cables.  With the power off.  Unplug the cables and plug them back up making sure they are tight.  If you do not have the motor cables screwed into the G540, screw them in.  If they come unplugged whiled powered up it can damage the G540.

If that doesnt help, run a back up of the XML.  Mach 3 keeps periodic backups, you can specify how many days or so you want to go back.

When mach3 does funky stuff, I re-setup a new XML and that typically solves it.  As mentioned in many threads its a good idea to keep a backup of your working xml on a memory stick.  I also like to take screenshots of all the settings that way i can quickly reset back up if the XML ever goes south.

This seems to be a pretty common issues these days, and is generally caused by one of two things.
1) loose wires for your direction pins
2)weak parallel port that can't supply enough voltage or current for the G540
