i3 Pro B X Axis Auto Home Issue

[shomili]

Hi

i just assembled the printer.

when i want to do the Auto Home function the X Axis starts moving and then stops completely.
i already tried to exchange the cables to the Y Axis but the problem then the Y Axis isnt moving.
Also tried to switch the Motor Controllers but the problem stays. It seems to be an issue with this
particular slot.

Would flashing maybe correct this issue? If so can you please provide me a link to the stock firmware.

thank you
kind regards

Sounds like it's locking up somehow.
Perhaps you should check the Vref on the particular driver.

Be very careful not to short out anything with the test leads or screwdriver.
Preferrably you should use a plastic or ceramic screwdriver when adjustiing.

I have set my Vref to 1.0-1.1V if I remember correctly.

Here's a link on how to do it: https://e3d-online.dozuki.com/Guide/VRE ... t+A4988/92

I don't think the firmware has anything to do with it.

Also try to to move the stepper drivers around to pin down the problem.

Oh my God! You saved me so much! I spent so much time trying to solve this. I couldn't even think to invert endstoppers because this is wierd. Thank you a lot! Now printing my first 3d-model on my hand-made RepRap printer.
