Same behaviour on X/Y drivers.

Thanks for testing.

At this point I'm not sure what to make of those motors. They sound awful to be sure. I would return them and get something else. Perhaps they aren't as advertised?

17HM19-2004S1 is what you listed above for the X and Y axis. For Z you had listed 17HS13-0404S1, which are you using for Z?

MartinNYHC

For Z it's

Ah, those are quite a bit different than what you had linked above.

Which I see now is actually the X Y motors, not your Z motor.

Unfortunately the Z motors you've got are not a great choice. They are very high inductance. They may still be usable, but you will need to reduce your max speed for z and they may still be loud. It also looks like you've got them set to use 600ma current when they are max of 400ma.

Try M203 Z300 and M906 Z300

These would be a much better choice: https://www.omc-stepperonline.com/nema-17-stepper-motor/nema-17-bipolar-1-8deg-22ncm-31oz-in-1-33a-2-8v-42x42x34mm-4-wires.html?mfp=148-bipolar-unipolar[Bipolar]%2C183-body-length-mm[34]%2C71-single-shaft-dual-shaft[Single Shaft]%2C21-shaft-type[D-Cut]

OMG, what have I ordered? I was quite sure that I ordered the one you suggested. Thank you very much vor investigating! Will give them back and get the other ones. Will keep you updated.

Phaedrux

I'd still be curious if M203 Z300 and M906 Z300 improved them at al. Probably still be loud though.

MartinNYHC

Yes, still too loud. Already initiated a replacement.

MartinNYHC

Another (dummy) question: when replacing the XY motors, do I have to adapt the steps? Since i upgraded the motors my printer is only moving half the way it should.

I was under the impression that nothing changes when using the old pulleys and belts.

Oh man....everything's not so easy

@MartinNYHC said in CR-10S Pro stepper recommendation:

do I have to adapt the steps?

only if you managed to get motors with different degrees/step. I.e. both 0.9 and 1.8 are relatively common as well as other values exist.

edit: but do carefully check the wiring and the direction they turn in once connected. standarized colour coding is not given with these things.

MartinNYHC

I just came ot my mind: I know have 0.9 steppers, the old one were 1.8. Doubled the steps and everything is good again
