Need help diagnosing bad stepper output signal on Duet 3
-
This stands out to me a little... I have no clue what any of it means. I just notice irregularities on driver 5 compared to the others
Driver 0: position 10480, standstill, reads 23950, writes 4 timeouts 0, SG min/max 0/149
Driver 1: position -6160, standstill, reads 23950, writes 4 timeouts 0, SG min/max 0/163
Driver 2: position 50304, ok, reads 23950, writes 4 timeouts 0, SG min/max 0/111
Driver 3: position 0, ok, reads 23950, writes 4 timeouts 0, SG min/max 0/111
Driver 4: position 0, ok, reads 23950, writes 4 timeouts 0, SG min/max 0/112
Driver 5: position 0, standstill, reads 23954, writes 0 timeouts 0, SG min/max not available -
The first thing that stands out is you have defined multiple E factors in your config but you only have one Extruder, I think you meant to set multiple Z factors.

Can you send M98 P"config.g" and report the results?

The rrf config tool originally gave me that setup
When I manually moved things from
M350 X16 Y16 Z16 E16:16:16 I1 to M350 X16 Y16 Z16:16:16 E16 I1
and so on for all the motor settings the bed would no longer home and the printer wouldn't function so I had to switch everything back -

If you run M98 P"config.g" again and it gives the same result as before, I think it's because you have multiple factors when you don't need them. If you tell the firmware the Z is 0.2:0.3:0.4 it knows to use one setting for all 3 steppers.

The Z axis only needs a single entry as well. It's only when you have multiple extruder axis that each axis needs to be defined. The other axis with multiple motors all use the same settings since they aren't independent.
So remove the multiple Z values as well.

@Rushmere3D JYNX again!
-
@Phaedrux haha
-
ok, haha
thank you so much for dealing with the noob over here. I corrected all of the lines after m671 to show only one value for X,Y,Z,E
I was just copying what the RRF config tool gave me for the multiple E motors since it did not have any option to add extra Z motors.
Z homing and G32 working perfect again, and I only have one data point for motor 5 now
Fingers crossed. -
as soon as the hotend heats up and it will let me send extrude and retract commands, I'll let you know if the ext motor is behaving any differently now
-
Hahahaha Phaedrux & Rushmere You guy are amazing!!!
wish I had asked a little sooner for someone to review my code... I really caused myself a couple of days of grief over here... I have good motor function on all motors now.
Now, I am off to tune my extrusion steps and try a print!|Thank You both soooooo much

Glad you got it sorted.

I still do have the
Error: in file macro line 21: M350: array too long, max length = 1but only for the M350 line
That's strange... what doesn't it like about my M350 X16 Y16 Z16 E16 I1

Please upload your actual config.g file
