The M671 command being in the wrong place was indeed the issue. I also had to adjust the maximum allowable correction to 2mm. Thanks again for pointing that, it would have taken me a while to find it.

@Phaedrux

I did not notice the order dependency on the M671 command, that is most likely the issue. I'll move that command around and see what that does tomorrow after work. Thank you for pointing that out.

I have a printer with a 3 motor Z-Axis and the pivot point connections are kinematic mounts. I keep getting an error when I have the duet3 6HC attempt to level the bed with the G30 commands. It will probe the correct locations (as close as I could get the sensor, a BL Touch, to the pivot points), however when it finishes the last probe, it kicks out the following error:

G32
Error: This kinematics does not support auto-calibration

I thought I setup the config.g and bed.g files correctly with the pivot points and probe points but it seems I’m missing something. It also doesn't seem to be moving the probe to the center of the bed during the initial homing even though the homeall.g file seems to be subtracting out the offsets. If i manually input the offsets it will put the probe where it should be.

What am I missing?

Below is my bed.g, config.g and homeall.g code

Below is bed.g, i commented out the while loop to see if that was the cause of the issue

@Q2101 Furter information, which may or may not be useful. I used the default values for the CAN address of the toolboard that the configuration tool provided, 121. The 6HC is board version 1.02 with firmware v3.5 RC3 running. There is a wifi module with the ESP32S3 chipset running firmware v2.1 B7 attached to the board as well.

The config.g file that the config tool generated is attached. The only change I made was to add the M552 1L S2 command to turn on the AP.

@dc42 They still do not light up after disconnecting everything. Only the VIN.

I am installing a 1LC toolboard v1.3 and i cannot get it to talk to the CAN on the 6HC. The Blue VIN LED lights up on the toolboard (it is dim compared to the 6HC's Blue LED) and none of the other LEDs will light up.

I have quadruple checked the wiring to make CAN1_L on the 6HC is wired to CAN_L on the toolboard and CAN1_H is wired to CAN_H, with physical inspections and continuity tests. I pulled the pins on the 1LC side and reversed them, just to make sure, still nothing. Re-spliced the cable connection between the RJ11 and the toolboard. Waited 30 minutes for them to decide if they wanted to connect. Still nothing.

The VIN powering the board is coming from the printers 24V power supply, and the GRD is tied to the ground as it is shown in the drawing. Pulled the board off the extruder to make sure the jumper was soldered.

For giggles, I tested the resistance across pins 1 and 2 on the 1LC side, im only getting 60 Ohms instead of the 120 Ohms shown on the drawing.

Is there something I’m overlooking or can check?

Was able to get the printer moving and without excess noise once the stealthchop was turned on.

Now I am running into an issue with the true bed leveling (G32) and the Mesh Compensation (G29) which is likely due to me not understanding how to configure it correctly. My z-probe is located (looking at it from the front of the machine) to the right of the nozzle along the x-axis and slightly in front of the nozzle along the y-axis. Going by the guide, this means that x and y should be negative when I set them in the config.g file using G31 correct? With this being a Pursa variant the two z motors are to the left and right of the bed, with the end stop (min) being on the right.

What happens is I will home the axis, which works fine. Then if I run the G32, it will home (as expected since G28 is in the bed.g file) then after home it will move to x=43.7(X0+43.7) and y=15.4 (Y10+5.4) to probe the bed, which is also my z offsets for the probe. It will then move to X=193.7, which will put this off of the bed. The same thing will occur with G29, it will start at X=43.7 and probe every 20mm until it is also off of the bed.

Thinking the z-probe offset might be reversed, I changed the sign, which sent the head crashing into the x endstop. Changing the 1st probe for the bed.g to X-43.7 got the first probe of G32 to probe in the right location, but it still goes off bed on the second probe. Im not sure what settings to change to get this working correctly.

Moving the head around manually, the positions I would expect it to probe(based on nozzle position) would be at X0 (the right side looking at the front of the printer) and X150 (the left side looking at the front of the printer), which keeps the probe over the bed.

@dc42 After doing some testing it seem the noise is related to the idle, as the motors made the expected amount of noise while in motion. Turning on stealthchop within M569 seems to have eliminated the buzzing/screeching noise.

@dc42

Opps, that fixed the servo control issue. Sometimes it is good to have another set of eyes looking at the commands. I'll try to remember M98 next time I make changes.

I used that guide to wireup the steppers before coming here and I did have 1 or 2 wired incorrectly at that time but they are correct now. What is odd, to me, is that I don't get the phase errors when driving them at 400mA vs the 500mA (which should be the max current rating for that motor).

I am in the process of rebuilding and updating an old Makerfarm prusa i3v 8" printer after the old ramps board died. I have been able to work through adding the second Z axis motor and getting all the microswitches to correctly register, however I am running into some other issues that have confused me.

The first issue is that I am unable to get the servo mounted z-probe to rotate (at all) into position for bed leveling. When the machine is first powered on you can hear and see the servo move (slightly) however I cannot get the M280 command to control it. I have the servo (a sg90 type hobby servo) with a microswitch (NO) plugged into IO_3 using in, out, ground and 5V.

The second issue I am having is that the motors are making a loud (buzzing/screeching?) noise. It is quite loud and as a temporary measure I set M84 to 10 seconds to keep the noise down while testing. Being new to Duet I am unsure what settings to change/adjust to reduce this noise. The model of the steppers is 42BHH48-050-24A. I tried turning Interpolation on/off and lowering the current to 400mA but that did not seem to have much of an effect. Setting the Z-axis to 500mA gives me an odd error of "Warning: Driver 0.4 warning: phase A may be disconnected, phase B may be disconnected Warning: Driver 0.3 warning: phase A may be disconnected, phase B may be disconnected" however this warning is not there when the steppers are set to 400mA.

Here it the code I have so far. Any help would be appreciated.
