Hello Thunderlaser Team, hello Ben!

I have a problem with my mars 90 (Nov 2011) - the x-axis doesn´t work anymore. It looks like there is no current at the stepper motor, i can move the axis per hand.

The cable of this stepper goes to a holder which looks like a relay holder. How and what can I measure to check if the stepper or other part is defect?
Or can you tell me which parts could have a problem in this case?

Attached you find a picture of the "holder".

Please let me know what I can do to find the problem.

Many thanks in advance and nice greetings from Salzburg/Austria

Best regards Joe!

Hello Joe,

Your mars 90 was brought in November 2011,it's very old machine.

To answer your problem,
1.The X-aixs doesn't work anymore,did you check the X-axis driver already?see below.
I wonder whether the driver be powered on or not. 2.The cable of Y-axis stepper motor goes to the relay,it's not X-axis motor.
Please verify which axis doesn't work indeed.

Hello Ben!

Sorry! - My mistake, it´s the Y-axis...
All drivers are running.

Please let me know what I can do.

Thank you, best regards, Joe!
