(moved complete config to reply below, as i had my config mirrored and corrected that for another issue but still see these warnings all the time during homing/movement)
sometimes #2 motor does it as well - #2 and #4 i believe are my Z motors.

@veti going to check this now, that was recommended by someone on facebook
-
I don't see anything in your config.g or homing files that would explain the problem, but you have a higher Z motor current than X and Y. What is the specification of your Z motors?
-
1.7 A/phase 82gcm2 1.8hms 3.06v from Zyltech. I'll drop the ma down to match the rest and see if that helps.
I disconnected the Z rods and did flags on them to make sure i wasn't missing anything obvious and they spin the right way (but 4 still complains)
When you have dual z - does #2 and #4 match any of the pins on the duet specifically? like is it the top or bottom pins or right or left motor by convention?
-
i printed benchy and i don't see this error while printing - only before and after. I have a different nema 17 I'll experiment with and see if a potential wiring problem is internal to motor. i recrimped ends to make sure it wasnt the plug directly to duet
-
Same problem here. 2 nema 17 in series, duet maestro, 12v, with all the currents, speeds and firmware versions.
Warning: motor phase A may be disconnected reported by driver(s) 2 going UP
Warning: motor phase B may be disconnected reported by driver(s) 4 going DOWN
Only stops whe using M569 P2 V670 or bigger value. But the motors are too noise to keep that value.
-
@cata said in Warning: motor phase A may be disconnected reported by driver(s):

I guess that stealthChop is interfering with the open-load detection then. Can you confirm that you are running firmware 2.02 or later? Do you have the specification of the motors? If they are low-current motors then to keep them quiet, you may need to connect them in parallel instead of in series, or connect them to separate stepper drivers.
-
@dc42 tested in all 2.03 betas and 2.02 stable.
Motors are low current, no data of the model or manofacturer.
Connected in parallel today, same warning with some "largue movements", 25 - 50 mm in one command.
Cant use another driver, dual extruder is setted
-
@cata
try reducing the maximum speed of the z axis.
-
@dc42 I am running latest firmware when i get this warning - only on faster movements. WHile printing i'm not seeing it.
-
@veti from 360 to 180 and now dont see the warning.
Then i cant use motors in series? Whats the point of the warning if my motors works well?
-
stealthchop2 has drastically reduced torque on 12v. you will need to upgrade to 24v.
there is an extensive video about it. https://www.youtube.com/watch?v=GVs2d-TOims
-
I'm already 24v

Only stops whe using M569 P2 V670 or bigger value. But the motors are too noise to keep that value.Driver 4 is the E1 motor output. What do you have connected to that output?
When you connected the motors in parallel instead of in series, were you able to use a larger M569 P2 V parameter without the motors becoming too noisy?
-
@dc42 said in Warning: motor phase A may be disconnected reported by driver(s):

Mistiping, both warnings are for driver 2

No, same noise
-
I've changed the code in firmware 2.03RC1 to disable the open load detection when in stealthChop mode. I expect to release that version later today or tomorrow.
-
@dc42 Thanks, i dont run for this but prefer to avoid the warning flood.
I will test again the conbinations when release the new firm.
