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

@dc42
Ok it works now not sure what I did wrong before, many thanks anyway!

By the way I had the surprise to see that
M669 S10
also modify segment length. It returns;
"Kinematics is Cartesian, 10 segments/sec, min. segment length 0.20mm, modified matrix:"
without any T parameter.

All good for me thank you for your support.
Alexis

PS: didn't find where to mark this conversation solved.

@dc42
Yes I saw it but no restart point / resurrect file is issued. I sometime run 24h jobs for finishing...
Only the index/line would be sufficent after M112 use.

RRF 3.5.4 is now onboard.

I need a emergency stop linked to an over/lower consuption of curent, detected by my annex arduino that wil prevent blind moves when spindle stops if I'm not there.
I configured a trigger but the buffered moves are sometimes 2/3 seconds if many straight moves in a row.

How would you suggest a 100% hardware approach?
I think I have no other choice but to consider the printing status otherwise I'll stop the mainboard when I change tool, or pause.

I added it now, and I still get the former type of response for M669.

@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?

Alex

I had that matrix;
