I've tested the new firmware and it's ok. No bug with M291. The print was well paused during all the process.
Thank you very much !

@dc42
I'm running in standalone mode with a Duet 2 wifi + Duex5. I haven't got Panel Due.

It seems be the same bug that @Argo has mentionned here :
https://forum.duet3d.com/post/228870

@dc42 I don't know.
Usually I'm in dual extrusion but I've broken a heatbreak, so back to M600

Hello,
I'm with RRF3.3beta3 and when I run M600, filament-change.g is called but the print resume between steps of the file instead of at the end of file :

G91 ; relative positioning
G1 Z20 F1200 ; lift Z
G90 ; absolute positioning
M291 R"Déchargement de filament" P"Rétraction en cours..." S0 T5
G1 E-100 F900 ; Retract fast
M106 P2 S0 ; led
G4 P200 ; pause
M106 P2 S1 ; led
M291 R"Changement de filament" P"Changez de filament puis pressez OK" S2
M291 R"Changement de filament" P"Chargement en cours" S0 T12
G1 E70 F300 ; Unretract and purge
M116 ; Wait
M106 P2 S0 ; led
G4 P200 ; pause
M106 P2 S1 ; led
M291 R"Changement de filament" P"Filament changé" S2

Somebody knows why ?

Hello. I had tried to connect to fan pin but there's not enough power for a laser of 40w.
You need to wire with a circuit like Duet says here :
https://duet3d.dozuki.com/Wiki/Laser_PWM_control
I've added a 12v power supply for the laser and now it's ok.

I've found. It was enough to write a G90 in the start code because my positioning of axis (park of X and centering of U) are in absolute coordinates.
Then Lighburn write G91 and no problem.
Is-it mean RRF turns relative mode when selecting laser mode ?

Hello.
I've a laser on U axis (mapped on X with the laser tool selected) who works very well with Lightburn for cutting (gcode generate in absolute mode) but don't works in raster mode (relative mode). I've asked to Lightburn developper and he said it's normal his soft do that.
If I use relative mode in printer mode, no problem, but in laser mode M452, relative mode don't work (Error: G0/G1: target position outside machine limits) . An idea ?

@dc42 @Phaedrux @oliof
dc42 has reason. My voltage is enough for each axis but limit for all axis in the same time.
So i've decided to installing a Duex5.

@Phaedrux
I think too... but I would like to understand

@oliof
It's no a problem if current is respected. I use two motors on same driver in X axis and no problem. And I done as you said for trying, so there is only one motor right now, and no good stall detection...

I've tried to invert driver with X and always the problem. As if my Y motors aren't compatibles with the stall detection.
Is it possible ? Crazy, no ?

@oliof
It's a good idea. I've tried and it is the same problem.
So 2 motors on same driver and the series wiring aren't the source of the problem.
I'm trying to invert drivers.

@Phaedrux
That's a link to a photo of Y axis :

The motors are biaxials and synchonysed by a shaft

@Phaedrux
Thanks for the calculation. I've confused the units of torque.

I've tried speeds up to 300 mm/s and differents current between 20 and 100% but nothing.

@Phaedrux said in Stall detection with 2 motors:

Well what behaviour do you want when a stall is detected? stop both motors or stop each individually?

I want to stop both motors. No choice, they're in series on the same driver.
This is the results of my M98 P"config.g" :
09/09/2020 à 22:16:49 M98 P"config.g"
HTTP is enabled on port 80
FTP is disabled
TELNET is disabled
Warning: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 365C
Warning: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 269C

Note my My PID aren't done for heaters errors.

@Phaedrux
And I'm not sure of my calculation of the H parameter and speed. This is my Y motors (2 in series) of my Y axis specifications :
Spécification électrique
Numéro de pièce du fabricant: 17HS24-2104D
Type de moteur: Bipolar Stepper
Angle de pas: 1.8 deg
Couple de maintien: 65Ncm(92.3oz.in)
Courant/phase: 2.10A
Tension: 3.360V
Résistance/phase: 1.60ohms
Inductance: 3.00mH ± 20%(1KHz)

I've found more than 1000 mm/s. It's crazy !

@Phaedrux
And I've tryed M574 Y1 S4 and indicate some differents M915 H parameters but no change. Force on endstop or false detection.

@Phaedrux
I understand trying to stall multiple motors at the same time is problematic but it's work on my other printer (nema23) and on my X axis on this one.
The only differences on this printer (nema17) with the 2 motors of X are the 2 motors of Y turn in opposate direction and are slightly stronger.
