Duet 3hc steppers not moving

G4 S2 ; wait for expansion boards to start
Can you try increasing your delay to 5 seconds?
Are the LEDs on the expansion blinking in time with the mainboard?
Is this a new build? Has this setup on the 3HC ever worked?
Can you send M98 P"config.g" and post the result?
-
The lights are indeed blinking in time with the main board as well as other can boards and all other boards are functioning correctly. It is not a new build, however, the 3hc is replacing two 1xd boards and 2 stepper drivers. I received the 3hc recently and it has not worked since I installed it. I also feel its important to note that there is no error reported by the drivers.
The only result returned from M98 P"config.g" is "M98 P"config.g" in green.

VIN voltage: min 46.8, current 46.8, max 46.8
What is your power supply voltage actually?
-
@Phaedrux that is the actual voltage of the power supply. It is a 48v psu
-
@knuxvomica I just checked it with a voltmeter to confirm and it is actually reading 46.8 directly from t he psu.
-
Can you post some photos of the 3HC driver area?
When and where did you purchase the 3HC?
-
I purchased it from filastruder on 11/03/22 and received it 11/07/22
-
Could you get some better lighting on there?
-
@Phaedrux
Sure

Thanks. I don't see anything obvious for damage.
Please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out.

@Phaedrux I was just wondering if the problem might be related to the fact that the OP has the board configured as board 10 seemingly without boards 1 to 9 being present? Might it be worth the OP configuring it as board 1 just to see what happens?
-
Worth a try, though I don't think there are any limits to the addressing as long as they are in the range.
https://docs.duet3d.com/en/User_manual/Machine_configuration/CAN_connection
3HC should be within 1 to 15.
In Duet 3 systems, each board has a CAN address, which is a number in the range 0 to 126. Each board must have a unique CAN address. The address of the main board is always 0. You can choose the addresses of the expansion and tool boards as you wish, however we suggest the following:
Use addresses 1 to 15 for Duet 3 Expansion 3HC boards
Use addresses 20 to 39 for tool boards
Use addresses 40 to 59 for external driver boards -
@knuxvomica I spotted this. From your config.g:
M569 P20.0 S0 ; assign physical drive 0 at can 20
M569 P10.0 S1 ;T2.6:2.6:5:0 ; assign physical drive 0 at can 10
M569 P10.1 S1 ;T2.6:2.6:5:0 ; assign physical drive 1 at can 10
M569 P0.0 S0 ; assign physical drive 0
M569 P0.1 S1 ; assign physical drive 1
M569 P0.2 S1 ; assign physical drive 2
M584 Y10.0 X10.1 E20.0 Z0.0:0.1:0.2 ; map drives
;Drive settings
M350 X16 Y16 Z32 E16 I1 ; configure microstepping with interpolation
M92 X160 Y160 Z320 E562 ; set steps per mm
M566 X1000 Y1000 Z500 E120.00 ; set maximum instantaneous speed changes (mm/min)
M203 X100000 Y100000 Z3000 E3000 ; set maximum speeds (mm/min)
M201 X4000 Y4000 Z20.00 E1500 ; set accelerations (mm/s^2)
M906 X1000 Y1000 Z1000 E650 I30 ; set motor currents (mA) and motor idle factor in per centFrom your M122 B10 report:

Moves scheduled 1, completed 1, in progress 0, hiccups 0, step errors 0, maxPrep 0, maxOverdue 0, maxInc 0, mcErrs 0, gcmErrs 0This indicates that driver 1 is correctly configured and 1 move has been executed, which has moved driver 1. However, driver 0 indicates 80 steps/mm which is the default, whereas your config.g maps axis Y to driver 10.0 and the subsequent M92 command sets the Y steps/mm to 160. So I suspect that some commands in config.g may not be working as intended.
Please can you try sending the M584, M92 and M906 commands manually from the command line with the same parameters as used in config.g. Then send M584, M92 and M906 without parameters to check that the correct values are reported. Also send M913 to check that all axes are set to 100% motor current. Finally, test whether you can make X or Y moves using e.g. G91 G1 H2 X10.
