Y axis motor just stops working

[Stephen6309]

Y axis motor just stops working, but X and the extruder keep going. Can move it with no resistance when it occurs. Pully is tight and belt is fine. Requires a reset to work again.

[Phaedrux]

Is there anything that leads up to this? During a print?
Do you get any errors in the console?
Can you get an M122 when it's stopped working?
Is this new with beta 7?

[Stephen6309]

@phaedrux M122 posted (first one) above and it's beta7. No errors in the console.

[Stephen6309]

@Phaedrux I noticed dc42 has released a 3.4.0beta+5 for the Mini and beta+4 for the 1LC, have installed them. Now to see if it happens again. The mini is in standalone mode.

Just remembered: the Y axis would lose some steps during the prior prints. I increase the Y current to 1100, which seemed to work. The Y axis is heavy. The bed is 1/4" mic6 and on a 2020 frame, 3/6" aluminum plate to the mgn12.
