Z-Axis Motor failed test

Hi, I have my Maslow since June 2018 and last week the z-axis begin to not grab the zero position and when I hit return to center the z-axis change is position every time I do it. I hit the “Test motors” in the Ground Control and only the z-axis failed the test.
Do I have to replace the motor or it can be another problem? And if I need to get a new one do I have to order it on Makermade site? Is the motor that is sold by Makermade is the same and fit on my kit?
Thanks!

I’m going to guess that there is a pretty high probability that with those symptoms you are just seeing a loose cable connecting to the z-axis. I would try unplugging and re-plugging that cable on both ends and see if the issue goes away.

Ok thanks bar, I will try this.

Hi bar, I try unplugging and re-plugging that cable and same problem. The motor make noise that I didn’t ear before. I opened the gear box and every thing seams working fine, I tried the test without the gear box and encoder cover open to watch and, same problème…

Can you send a picture with the cover off?

That all looks pretty good. I don’t see anything visually wrong under there.

I’know… I switched the z axis motor with the left one on the back of the board and make the motor test and this way is the left motor who failed the test. So I don’t think is the board. Do yo know a similar replacing part that is sold on amazon or I have to order it on makermade site? Thanks again bar.

Happy to help, I’m sorry I haven’t told you anything conclusive. There isn’t really a drop in replacement available on amazon so makermade might be the best way to go. I haven’t really seen an encoder fail before when there wasn’t something physically wrong with it.

Thanks bar, I will order a new one at Makermade. I’ll post an update when I replace it.

Hi, I bought a brand new kit from MakerMade CNC. Im here in South Africa. This weekend i finally got time setting everything up and from the get go my Z-axis didnt work at all. No movement and failing tests
@bar @makermadecnc.

Please help,

What do you see on the tests if you swap the wire from the z-axis with the left motor?

Hi there,

I have found my self in the same situation and I read the trouble shooting. I would suggest to double check closely the cable connections as it is quite hard to spot a broken cable as seen on the picture.

Hope it will help @M-Mo and @Hidden_Customs.

Hi thanks,

@MakerMadeCNC shipped me a new motor after I did all the tests without any success. I appreciate the post though. I went ahead and made new cables as spares also when testing.
