Driver fault- repeat in 2 boards

droftarts

@moo16 in your config.g, it’s best to put in motor settings for all extruders, even if they’re the same as the first. e.g. you have M350 E16 I1, change to M350 E16:16:16:16:16:16 I1. Do the same for M566, M203, M201.

Do you have a mix of extruder driver motors? You have set the current for some of them very high at 2500mA with M906. Check you are not over heating the motors. You may need additional cooling on the stepper drivers, as you’re running them at close to their maximum current rating.

for sure its not a crimp fault, i changed many cables and i crimp like a pro :-} so i can eliminate this for sure.
the soldering issue sounds like something rational, i can see the soldering behind the driver is bit flimsy (can upload pic).
about the Power supply it may be the problem but im using 24v/600W PS In my calculations this should be enough current for a lot more drivers(lets say i drive 3 axes and 5 tools motors).
any idea ?
and thank you very much

Do the warning messages report only one phase of the motor open circuit, or both phases? See my previous reply.

@droftarts
yes im using mixing of extruders.
i will apply setting for all extruders. the M906 setting are set at 80% of the current motors.

both phases report frequently.
same driver always appear even sometimes when im not driving that driver it report his phases.
like i said motors current set to 80%.

What is the motor specification?
What VIN voltage are you using?
What current have you set?
What firmware version are you using?

@dc42 said in Driver fault- repeat in 2 boards:

hat firmware version are you using?

all mentioned up:

neema 17(https://www.oyostepper.com/images/upload/File/17HS24-2104S-PG5.pdf)
24v/600W power supply
for this motor i set 1700Amp with M906.
my firmware version is 2.05 rrf .

Thanks. Are the drivers which report the problem driving axes or extruders? Do you get the message only when you command high speed motion of the motor? If so, at what speed, and what is the steps/mm for that axis or extruder?

If you get warning messages for both phases, it it unlikely to be a problem with the drivers, it's probably a false report from the firmware.

@moo16 From your other threads (please just use this thread or it just gets confusing):
https://forum.duet3d.com/topic/16767/heater-leds-always-on-pic-attach
https://forum.duet3d.com/topic/16769/stepper-motor-buzzing-and-not-moving

I think you have changed the Duet and Duex board. Are you still using the board with the heater LEDs on? Also there's tape across some of the stepper drivers? Or are you using a different Deux without these issues?

Also from the other thread, is this your current config.g settings?

M584 X0 Y1 Z2:4 E3:5:6:7:8:9      ;  Use E1 for Z axis

M201 X500 Y500 Z100:100 E600:100:600:1000:100:1000                     ; Set accelerations (mm/s^2)

I know I told you to add the 'Enn:nn:nn:nn:nn:nn', but you should also REMOVE the second number for Z, ie change Znn:nn to Znn, in each gcode. The firmware should ignore the second number, as you can only set one motor parameter per axis (extra parameters are allowed on extruder axes, because they are separate axes), but in some cases in older firmware it can cause the next motor to use the second Z value. So change your config.g to:

M584 X0 Y1 Z2:4 E3:5:6:7:8:9      ;  Use E1 for Z axis  

M350 X32 Y32 Z16 I1                      ; Configure microstepping with interpolation
M350 E16:16:16:16:16:16 I1		;microstepping without interpolation 
M92 X157.63 Y158.96 Z400 E115:8:115:50:8:115                  ; Set steps per mm 
M566 X1200 Y1200 Z24 E800:1000:800:1000:1000:1000                       ; Set maximum instantaneous speed changes (mm/min)
M203 X30000 Y30000 Z600 E4000:4000:4000:15000:4000:15000                 ; Set maximum speeds (mm/min)
M201 X500 Y500 Z100 E600:100:600:1000:100:1000                     ; Set accelerations (mm/s^2)
M906 X800 Y800 Z800 E2500:1700:2500:1300:800:1500 I20                 ; Set motor currents (mA) and motor idle factor in per cent

Also, your accelerations and max speeds across all extruders seem very high, particularly for a mixing extruder, where there is usually even more resistance to extrusion. This is probably why the motor is 'buzzing'. You have:
M566 maximum instantaneous speed changes (mm/min) = 800 = 13mm/s
M203 maximum speeds (mm/min) = 4000 = 66.6mm/s
M201 accelerations (mm/s^2) = 600
What command are you sending to move the extruder? Most likely it can't suddenly jump to 13mm/s, which is causing the error. Try something like:
M566 E120.00 ; set maximum instantaneous speed changes (mm/min)
M203 E1200.00 ; set maximum speeds (mm/min)
M201 E250.00 ; set accelerations (mm/s^2)
and work up from there to find the maximum speeds and accelerations.

Finally, this microstepping line: M350 X32 Y32 Z16 I1. X and Y will not be using interpolation. The TMC2660 stepper driver in the Duet 2 Wifi and Duex5 only support interpolation with microstepping set to x16.

with microstepping set to x16.

i have 2 boards of duetwifi(main), and 3 boards of duex5.
so the "always on heaters" is for one of the duex5 and i open a thread for this, im not using it anymore, the tape on the drivers is for sign this as faulty.
my other 2 duex boards describes the problem in this thread, it happen with my 2 main boards and with my 2 duex5 as same the only difference is the drivers that reports are different numbers of drivers in each board.
my 3rd thread is about "buzzing" motor which was being checked on one of my main boards but it not related to this thread(at least for my opinion).
so i very sorry if i make it difficult to follow but this is 3 different faults on several different boards.

yes, the config you had upload is my current setting.
im sure your information and experience will help me solve this just give me any data that you think will be helpful.

i will fix the config as you say and try again + try lower values for the extruders.

hope it is understand feel free to ask quetion.
thanks again, mooo

@dc42
look up for my config file <<<---
the problem appears only at extruders drives.

ok,
@dc42 @bearer
firstly, i closed all my open topics as you requested.
this problem(this post) probably was sourced with disconnecting and connecting the driver while current is applied to phases, i think it damage my drivers and finally damage the board.
another speculation is that the boards had been damaged by ARC that damage the boards and the drivers.
right now i have 1 main board with faulty drivers and 1 expansion with some faulty drivers(later become not responding at all).

i see it close issue. so i mark it as solved for now. appreciate your help
if you have any other ideas please share it with me.
thank you again
