[3.6.0-beta.4] DWC Connection

@Leonard03 you could add a M99 command part way through mesh.g to quit the macro at that point, then see whether DWC still disconnects. Move the M99 command around until you have found the line that causes the disconnect.

Does mesh probing complete before DWC disconnects? I have a feeling that the M300 commands near the end might be triggering the problem.

You have a M80 command near the start. If this is because you sometimes have only 5V power applied when you start the macro then you may need to add a delay command after it, to allow the stepper drivers to be initialised after VIN power is applied but before any movement commands.

Adding the M99 between G32 and G29 S0 (at line 20) works. After that, DWC starts looping.

Yes, the mesh always completes and the disconnects seems to occur at the end of the macro, but again, G29 S0 sent alone from the console works with no problems

That M80 I use mainly to override the M81 S1, but I agree, I will change it to make it safer

@Leonard03 I suggest you open mesh.g in the DWC editor, then delete the G29 S0 line and re-type it. There could be a non-printing character in that line that line that causes it to malfunction, for example if the S0 is not being recognised then it will call mesh.g recursively.

What type of Z probe are you using?

@dc42 Tried now. Verified in DWC editor and Notepad++ there were not strange characters, but redo it anyways, but with no success..
Tried commenting out all the if else statements, no luck,
Tried commenting out beeps at the end, no luck,
Tried to add a M400 in combination with G4 S3 between G32 and G29 S0 first, and after the mesh after. no luck either

I have a BL Touch
This is its configurtion, if this helps:

; Z-Probe
M950 S0 C"!exp.heater7"										; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H4:2 F240:120 T9000 A20 S0.01			; set Z probe type to bltouch and the dive height + speeds S0.005
G31 P500 X-27.4 Y-28.6 Z2.00								; set Z probe trigger value, offset and trigger height
M557 X8.0:285.0 Y21.6:279.4 P10								; define mesh grid
