Difference between M28 and manual upload of Gcode

JBisc

Hey evrybody

I am currently facing the problem, that there is a different behaviour by using M28 or using manually upload of a Gcode file over Duet Web Control

if I use M28 (by M28 "0:/gcodes/name.gc")), some commands of my uploaded file are deleted:

for example all command G4 P100 are deleted.

If I am using the some file and manually upload it, it does not happen.

Do you guys habe any idea? I am running out of ideas.

Newest firmware used.

Please be specific. What version of firmware and DWC are you using. And what board?

Thanks, that's helpful. I'm not sure if this is intended/expected or not. That will be for @dc42

Uploading files using M28 should not remove any command lines. However, AFAIR it does remove comments. Are you certain that your G4 lines are not commented out with a semicolon at the start?

JBisc

Yes I am sure that nothing is commeted out.

Here is an example:

If i send the following gcode


M106 S1.0

G4 P25

;M106 S1.0
M106 S0.0
M106 S1.0
M106 S255
M106 S1.0

G00 Z0.000000
G00 X105.324704 Y211.976535
M106 S1.0
G01 Z0.000000 F100.0(Penetrate)

the final file on the duet looks like

G4 P25
;M106 S1.0
G0 Z0.000000
G0 X105.324704 Y211.976535
G1 Z0.000000 F100.0;Penetrate

I am not understanding what is happening here.

Are you running your Duet 3 in standalone mode or with an attached RPi?

JBisc

@dc42 Attached RPI on which a python script sends the commands.

I'll ask @chrishamm to take a look at this.

@dc42 Great thanks a lot!
