Oh that's a really good tip thank a lot Jay

@gloomyandy I now updated my firmware, M122 confirms with :
RepRapFirmware for Duet 2 WiFi/Ethernet version 3.5.4 (2024-11-24 10:43:42) running on Duet Ethernet 1.02 or later

M669 answer is unchanged though;
Kinematics is Cartesian, no segmentation, modified matrix:
1.00 0 0 0
0 1.00 0 1.00
0 0 1.00 0

Thanks you again

After researching I would do that;

M950 P2 C"exp.e3stop" ; output 2 uses e3stop pin

If state.status == "processing"
M42 P2 S1
else
M42 P2 S0
break

In a macro or in the user config file.

@gloomyandy
ok i get that. I will update my firmware soon.

And how does that cut the segments?
In your example; "2 segments/sec, min. segment length 1.5 mm" are shorter segment than 1.5 mm kept or is it ignoring shorter moves?

Hi everyone,

On a duet 2, RRF 3.3 controling an original Z1+ workbee.

I am struggling configuring an emergency stop that is instantaneous AND offers a resume possibility, I am thinking of going for an external relay cutting power.

The relay would be controled by a arduino controling the spindle current consuption (that I already use with trigger).
I need to condition the relay opening to the printing status as the R parameter of M581.

So is there a way to configure an output pin reporting that status?
Many thanks

Ok perfect I could restart from the desired index thank you two.

There are many things I don't get on M24 though, It is using the resurect file, but modifying the M26 line of the resurect file does not modify the resume index. I guess there are hidden actions at a deeper level!
Is there any documentation I can read to understand it better?

I had that matrix;

M669 did gave me the actual settings.

The segmentation matrix has not been modified by M669 S0.1, nether by M669 S0.1 T1
In case the value was not acceptable, I also tried M669 S2 T2 that also had no effect.

Any idea of a better place for the command?
Should I update to RRF 3.5?

Well I tried adding M669 S0.1 in the user setting file but nothing changed.

T parameter sets the minimum segment length and I want to reduce it so I didn't use it.

Oh that's a really good tip thank a lot Jay

Hello everyone,

Configuration; rep rap 3.3 on duet2 (ooznest workbee)

After a power cut on a very long job, I'd like to restart job, but before the position stored on the resurect file, because the cuting tool was broken so no cut was made during the last (?) 5 minutes.

the resurect file gives me :
M26 S1484811 P0.474 X552.682 Y567.508
The file is 10 Mo, 197000 lines...

So i'd like to manually reduce the restart index to go back in the file, then simulate to check my roughing layer. But the bit index has to correspond to the start of a command, so is it possible to get the bit index of a line in a gcode file?

Thank you
