Need help diagnosing bad stepper output signal on Duet 3

Noah · 13 Feb 2021, 22:11

I just setup a brand new duet 3 board with a Pi.
I have X,Y,Z1,Z2,Z3 on drivers 0,1,2,3,4 and the extruder on the last driver #5. I have tried 3 different motors and then switched the extruder motor around with a Z motor by just swapping connectors from one of the 3 Z motors at the board. When the extruder motor is plugged into driver #4 it runs perfectly, and on the same cable just plugged into a Z motors driver when I manual raise or lower the bed.
So the motor and cable is definitely working fine. I am wondering if the brand new board I have just happened to come with a bad driver or something?
I have tried many many amp settings and accel and step settings... not matter what any motor I connect to driver #5 just makes a faint hummm and rarely will even start to rotate. If I help the shaft along while it humming it will go.

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

@Noah

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 remove the multiple E values from this section? You only have a single extruder, so there should only be a single E value.

Phaedrux · 13 Feb 2021, 22:20

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

Noah · 13 Feb 2021, 22:24

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

Same result again. The triple Z bed no longer homes or responds to G32

Rushmere3D · 13 Feb 2021, 22:46

@Noah

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.

M350 X16 Y16 Z16 E16:16:16 I1 to M350 X16 Y16 Z16:16:16 E16 I1

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.

Phaedrux · 13 Feb 2021, 22:46

@Rushmere3D JYNX again!

Rushmere3D · 13 Feb 2021, 22:47

@Phaedrux haha

Noah · 13 Feb 2021, 22:56

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.

Noah · 13 Feb 2021, 22:57

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

Noah · 13 Feb 2021, 23:05

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
