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

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.

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

Re: How to use M915 T parameter

Hi,

My configuration is a duet2 board with rep-rap 3.3 on a workbeeZ1+.
I'm trying for a while to have an emergency stop that is not waiting for buffered moves to finish, AND offers a resurect file generation (or at least stop index of SD file interupted)

Could M915 does that ? After what I red I understand that it won't be efficient at high speeds, and not necessary reliable, not sure if the stop comes before or after the buffered moves.

More in details, because I sometime run 24h roughings and more for finishings (you can see my creations at BoisEtReliefs on etsy if you like!), I had spindle stop, coal used, wire cutted, etc leading the workbee moving 3mm deep with ½ inch tool not turning... and that for 30 minutes the first time, the nightmare.

I now use a real time current check arduino module with trigger T1 to pause but the buffered moves take sometimes long time before the stop especially for the 1m straight cut of the beginning of some creations, and I recently broke a tool.
So if M915 is instantaneous, and offers a saving point it would be gold for me!
By the way, is it possible to use trigger T0 (instantaneous M112 stop) and create a resurect file, or any restarting point save?

Otherwise I will go for a dedicated relay on power supply associated with the arduino module.

Thanks a lot.
