I have a quite similar Problem:

I want to switch a on/off realy to switch the spindle via the M3/M5 command.

The relay is connected the fan port 7 of a Duet3 board.
I configured the following lines:

"M453 P7 S0 T0 C"out1+out7+out2" ; set CNC Mode"

Result:
"M3" does not switch the relay, but "M3 S1" does.
"M5" stops the spindle, as intended.

How can I configure the board, so I can switch the spindle with "M3" only, without M1, because this is how the gcode ist generated my the postprocessor?

Great work! Compliments!
I just started to modernize my cnc mill with a duet3 board, too.
Basically it is running, but some configuration is still to be done.

May I ask you a few questions?

I use Fusion360. What postprocessor do you use?
How do you manage to start/stop the spindle (just a high voltage relais)?
Does the postprocessor create the M3 M5 commands?
How do you z-probe?

Some help would be great!

You are the best! Looking great!

Could s.o. please post the config.g and the homing files, for a e axis mill, so I have a starting point for configuration?

I did not manage to install the CNC Webcontrol. The duetwebcontrol_sd.zip can be uploaded under „system“, the files are unzipped, but then nothing happens.
What is my mistake?

What's the latest firmware version known to run stable?

2.02 was the last stable release.

What version of DWC and PanelDue firmware are you running?

I downgraded to 2.02 and all is running fine again. I kept DWC 2.0.0, no problem with this.

Within long prints, the display and the web interface twice got unresponsive about in the middle of a print (after around 5h).
But the print was finished correctly. After finishing, the duet display (7´) and the web interface still show the bed and hotend temperature that where used during the print.

I also observed that!
At first I thought only of wireless problems but also the PanelDue did not react anymore.
I also had this in 2.03 RC, Final 2.03 I have just installed today.

Since updating to 2.03, I think, that there is a new issue.

But the print was finished correctly. After finishing, the duet display (7´) and the web interface still show the bed and hotend temperature that where used during the print.

The "STOP" button on the display reacts, but failed to connect to the duet board again.

Power on/off fixes the problem.

In the 2.03 RC the fault did not appear.

For homing and bed tilt leveling I use the endstops. The probe is only used for mesh bed leveling from time to time.
I thought, the Z-offset of the probe does not matter, because the probe is only used for generating the heightmap and leveling is done by the endstops, anyway.

; homez.g
G91
M584 Z2 U4 P4. ; split Z motor control to Z and U for it to work we have to show U (param P4) in the UI
G1 S2 Z6 U6 F6000 ; move bed down 6mm
G1 S1 Z-300 U-300 F4000 ; move quickly to Z axis endstops and stop there (first pass)
G1 Z2 U3 F4000 ; go back a few mm
G1 S1 Z-300 U-300 F300 ; move slowly to Z axis endstops once more (second pass)
M584 Z2:4 P3. ; back to combined axes and hidden U
G90 ; Back to absolute positioning
G92 Z4.66 ; Z offset (positive is closer to bed)
G91
G1 Z5 F3000 ; lift Z after probing
G90

Hi!

My Z-Offset is increasing about 1mm with ever print. If I restart the firmware, it is not increasing.
The heatmap is under the Z= level - may be this has to do with the problem?

Setup:
Duet Wifi, Slicer S3D
Bed leveling is done with two optical Z-min endstops and two steppers - working fine.
Than the stored heatmap is used vor auto bed leveling.

Autobed leveling is done with a precision piezo orion probe.

config.g:
; Z-Probe
M558 P8 I1 R0.4 F300 T10000 H1 ; Set Z probe type to unmodulated and the dive height + speeds
G31 P500 X0 Y0 Z0 ; Set Z probe trigger value
; Endstops - empty

The sequences before printing are:

Set the Z-offset in homeall.g and homez.g
G92 Z4.66 ; Z offset (positive is closer to bed)

In the S3D start-script home all axis and activate bedleveling with the stored heatmap:
G28 ; home all axes (homeall.g)
G29 S1 ; enable mesh grid compensation from saved file

Any ideas?
