M915 feature is loss after 3.5.0 beta2 version on extruder

@chrishamm I am not sure why, maybe H1 is never been tested for ST yet. However the restult is as my test reported.

@chrishamm said in M915 feature is loss after 3.5.0 beta2 version on extruder:

@hestiahuang I've checked the underlying code and there is no notable difference between the code used on the Duet 2 and 3. G1 S is only supported in Laser mode and the S parameter is ignored otherwise in 3.5-b3. Only G1 H1 moves can use SG for filament loading. If you are still on an old RRF version, this behaviour may be inverted, i.e. G1 S1 stops when the extruder stalls and G1 H1 acts like a normal move without SG detection.

Please send the output of M122 from your machine.

Let me try explain more what my config.

The whole macro can run fine after I change "H" back to "S". No other extra change.
code like this

M201 E10000
M915 P3 S6 F0 R0
G1 E-1 F300
G1 E60 F300
G1 E800 F4800
M201 E1000
M913 E28
G1 S1 E200 F1500
M915 P3 R0
M913 E100
M201 E10000

I really not config the M201.1 in my config.g. I guess it is defaul by the firmware. My machine is E3D ToolChanger.
Simulation steps like my macro code about.

M201 to set the acceleration to 10000
Define the ST
Retract 1mm avoid to trigger ST detection
Run extrusion and load the filament slowly
Load filament fast
M201 to change the acceleration to 1000
Change ST detection current to 28%(full current is 1250mA)
G1 S1 E200 F1500 => Extrude 200mm with 25mm/s, ensure it ST can be captured(Howere there is no move if it is H1, it is working fine it is S1)
Turn off ST
Resume 100% current
Set the acceleration back to 10000

@hestiahuang on a G1 H1 move with a stall endstop enabled, the M201.1 acceleration is used instead of the M201 acceleration. So try removing the M201 commands from your macro and instead adding M201.1 E1000 to your config.g file or to that macro.

Noted and thx, I can't wait to try now.

Just tried. Result is the same as before.

```
M915 P3 S6 F0 R0 ;Define the ST
G1 E-1 F300 ;Retract 1mm avoid to trigger ST detection
G1 E60 F300 ;Run extrusion and load the filament slowly
G1 E800 F4800 ;Load filament fast
M201.1 E1000 ;M201.1 to define the acceleration to 1000
M913 E28 ;Change ST detection current to 28%(full current is 1250mA)
G1 H1 E200 F1500 ;Extrude 200mm with 25mm/s ====>tested and found there is no move(no extrusion)
M915 P3 R0 ;Turn off ST
M913 E100 ;Resume 100% current

What my point is if the same macro, and the change is only from S1 to H1 and M201 to M201.1, why it is not working now. What change else I should implement?

dc42

@hestiahuang only two of us at Duet3D have Duet 2 systems that could be used to try to reproduce the issue you are experiencing, and both of us are away at present. I will be back next week so I will try to reproduce it then.
