I NEED HELP! PLEASE!
« on: October 19, 2012, 03:50:33 PM »
I have been using my machine for several years now without fail. Then I am jogging wy y axis and it quits moving and starts making a horrible noise.
Also notice e-stop quits working. Diagnostic screen has a green light at pin 5. I have an xtra plt port, so i switch to that, same problem.
Switched cables, same problem. Swapped cable to x axis and y hot keys move motor and vise versa, so driver and motors ok.
I re-installed Mach, same problem. If anybody has any ideas, please let me know, I am at a loss. I have attached my xml.
Thanks, Matt

What cables did you swap? Did the motor that was not working then work fine?

Sorry, I just hooked the z axis cable to the y pot of the gecko 540 and got the same
problem with the z motor. does this mean i have fried my gecko?

Ok but what cables did you swap? Drive to motor? Drive to Breakout board?

Oh Ok so its a gecko G540, yes does sound like the issue is a dead drive. Do you use the 4th axis? If not swap the drive from that to the one that doesnt work and se.

I am using a gecko 540 and I swapped the cable from the z motor to the y output on the gecko. FAIL
But if I hook cable from y motor to z output on gecko, I can drive y motor with z hot keys.
I hope this makes sense!

THANK YOU!
Yes, swapping it to the 4th axis worked. Although my e-stop syill does not work.
All other limit switches work fine???
Any thoughts on that

Ok you have not really confirmed anything other than the motor is ok, what you really need to do is physically swap the drives around. I have never had a G540 but I think its relatively easy to do.

Regarding the E-Stop you need to check the switch itself and the wiring is good, if it is then it could be the G540 motherboard that is the problem or it could be your Mach config.
