I first had this issue with 1.19 but then updated to the latest 1.20 from github.

For the over temp messages i don't recall seeing anything, i will check the chip tonight and try to feel if it is hotter then the other ones.

Hello,

I am hoping someone can help me diagnose this issue where any motor that i connect to drive 4 starts working good but after a few movement will seem to get stuck and bind on something. Everything goes back to normal when i power the board off/on again.

I have first encountered the issue while splitting my Z axis on Drive 2 and 4 and then realized i did not had this issue when using drive 2 and 3. Since then i tested different stepper connected to it without anything attached to be sure it wasn't caused by some mechanical resistance.

I figured i could try using Drive 4 as the extruder but then again i get the same behaviour where the motor will seem to jam and heat up.

I have a dual z axis and i am using the following config:

; General preferences
M111 S0 ; Debugging off
G21 ; Work in millimetres
G90 ; Send absolute coordinates…
M83 ; ...but relative extruder moves
M555 P2 ; Set firmware compatibility to look like Marlin
M208 X0 Y0 Z0 S1 ; Set axis minima
M208 X300 Y300 Z400 S0 ; Set axis maxima

; Endstops
M574 X1 Y1 Z1 S0 ; Define active high microswitches
M558 P4 I1 X0 Y0 Z1 H5 F120 T6000 ; Set Z probe type to unmodulated, the axes for which it is used and the dive height + speeds
G31 X-40 Y-0.10 Z0 P25 ; Set Z probe trigger value, offset and trigger height
M557 X20:280 Y20:280 S50 ; Define mesh grid

M584 X0 Y1 Z2:3 E4 ;enable dual z steppers (right is drive 3, left is drive 2)
M671 X-20.0:325.0 Y100.0:100.0 ; leadscrew offsets from home

; Drives
M569 P0 S0 ; Drive 0 goes backwards
M569 P1 S0 ; Drive 1 goes backwards
M569 P2 S1 ; Drive 2 goes forwards
M569 P3 S1 ; Drive 3 goes forwards
M569 P4 S0 ; Drive 4 goes backwards
M92 X80 Y80 Z400 E95 ; Set steps per mm
M350 E32 I1 ; Configure microstepping with interpolation
M350 X16 Y16 Z16 I1 ; Configure microstepping with interpolation
M566 X1200 Y1200 Z24 E300 ; Set maximum instantaneous speed changes (mm/min)
M203 X30000 Y30000 Z600 E3000 ; Set maximum speeds (mm/min)
M201 X500 Y500 Z100 E5000 ; Set accelerations (mm/s^2)
M906 X800 Y800 Z800 E800 I30 ; Set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout

If needed i can provide a video of the issue.

Thanks!
