Some problem of electronics

Hello

I'v constructed a RepRap Prusa Mendel for almost a month. And I've bought an R2C2 3D Printer controller for my 3D printer.

I connected all the electronics include stepper motors , extruder, and endstops. In the software, i told X,Y and Z axis to move to "0 position". They moved to the correct direction, but some of the step motors stopped without reaching the their endstops. Others were still moving even they reached their endstops. I've checked around , all the connectors were seated properly. And the endstops were also working...

What should I do?

have u any product service warrenty ?

From description it seems certain axis stops when some other axis endstop is triggered, then first axis endstop is never reached to stop the other motor from moving.

I think endstop configuration may be wrong, so perhaps double check connections of endstops with connections of motors.

Perhaps endstop X is mounted onto Y axis and vice-versa - or something like that.

Have you tried the M119 code to see what endstops the printer thinks are triggered? If it's endstop related, this is probably the most useful tool you've got.
