Mach 3 Slave Axis problems.
« on: February 18, 2010, 05:39:08 PM »
First of all I just wanted to say hello to everybody.  This is my 1st post on the forum and sadly it has to be a problem.

I have a gecko g540 running 4 stepper motors.  I need to slave the A stepper to the X stepper to drive the dual Rack and Pinion gears.  Here is what I have ch3eck3ed so foar.

1.  Downloaded the Gecko G540.xml from the geckodrive website.
2.  Checked to make sure that the motor was enabled in ports and pins. 
3.  Set the slave options under the config menu to slave a to X
4.  Unchecked the Rotational checkbox for A axis in general config.
5.  Tested the motors on X axis and they all test good.
6.  Checked the home slave checkbox.

I still can not get the A stepper to move.  If anyone would have any insight into my problem I would really appreciate it.  I am attaching my xml file for review.\\videos

Xml looks fine from first look. Not familiar with the G540 , could you need an enable of some sort on the A axis drive?

There are no switches save the charge pump switch.  I have that off at the moment so the drive will come out of fault.

What about if you change the pin assignment for X and A, does the A axis now move and X not?
Can you physically swap the drives around in these G540 easily, if you can it might be a good idea to swap out the X and A and see what happens, could be a bad drive.

Hood the G540 is an all in one, i do believe that they use sub d plugs and sockets

Crash5050 MAKE SURE YOU POWER DOWN AND WAIT BEFORE UNPLUGGING THE DRIVES

Other than that i can offer no other advice

I thought the G540 had individual drives inside it so you could swap out if one went bad. Not sure how easy it is to do that though but I am 99% sure it is.

Edit
Now I am 100% sure, Geckos site says it uses 4 G250 drives and "Easy to service, removable drives"

Hood yes but as the motors plug in it's easier to swap plugs. ;D

But that wont tell you if its a drive fault or some config/mobo fault, he has already said both motors work on X ;)

My gecko does not have the option to move the drivers, they are static on a motherboard that attatches to the main board.
