Well I am in the process or upgrading my Tool changer to Duet 3 and 4 Toolboards with a distribution board, but I am using high temp heaters and pt100 sensors,s there is a daughter board connection on the main board for the 2 pt100 sensors but not on the toolboard, in the documentation it is only stated that the tool board supports thermistors or PT1000 sensors, so my question is dose that mean I can not have all my tools use pt100 and for the 2 available I will have to run wires from the tool to the main board instead of having every thing connected to the toolboard or am I miss reading the documentation,

Thanks in Advance,

It seems there is a bug with DWC when printing a file sliced for sequential printing the counters go crazy precentage is going down not up, job time and layer time seem to not reset after the first object completes, A screen shot is attached for refrence Ifthe Gcode file is needed I will upload it as well

I understood what you want to say just now, english is not my first language, I will try it and report back.

but that is not the same is it, M452 sets the machine to "laser mode" S1 enables sticky mode exactlly the same way the firmware interprets the feed rate it takes the first instance of the feed rate and only changes when you issue a move or G0/1 command with F parameter other wise the feed rate is the same although you don't have to put it in every move command! Fan pwm in this example is a totally different setting that has its own commands.

The weird thing is that I can not find any mention of the S1 parameter fo the M452 command in the Duet Documentation

Correct me if I am wrong, but my understanding is that the M452 S1 should enable laser mode with sticky pwm value meaning once I issue a M3 S150 for example then all G1 commands that follow until a M4 or M3 Sx is issued laser should be on with power 59% (100*150/254). That is not happening so I am asking am I setting it up incorrectly or is this a bug or has this feature been disabled for some reason

I am refering to @dc42 statment in this post

@dc42 said in Laser turns off after following code is sent after M3:

Advance warning: in 2.03beta3 the G1/G2/G3 S parameter will only be sticky if you add parameter S1 to your M452 command.

which I did but it dose not seem to work!

So I have been working on a tool for a laser engraver on the tool changer. I have designed a mount for the laser on the tool changer but I think it still needs some tests, which brings me to my question as I am testing the laser I am trying to make sure the mount has enough air flow going through it to cool the laser diode as well as push the smoke away to prevent charring and so on,My problem is as follows;

I created a new tool ( as the mount i designed is a bit deeper than what is allowed on the tool changer I am mounting it manually for now), Disabled heater 5 and in the tpree4.g file I set the machine into laser mode using the M452 command (M452 P5 R255 F200 S1). when I try to do cut moves the laser only fires for the first move then dose not fire again until the next M3 Command where it fires for the first move again, I have searched and under stood that this is a safety measure implemented in the duet firmware and my understanding is that using the S1 parameter should enable sticky mode but that is not the case, I am trying to find a solution other than a post processing script. I am using LightBurn for the laser gcode generation. a sample of the gcode is below for reference.

If you can spot what am I doing wrong I would be grateful.
