@OwenD It is definitely more code to to have it auto calculate heating rates and timing depending on set temps however my current solution is not that complicated as per what tony said but requires knowledge of manually finding out the times:

M140 S[first_layer_bed_temperature]; set bed temp
M116 H0 S10 ; wait for heater 0 (assumed bed) to get within 10C of the target
M104 S[first_layer_temperature]; set extruder temp
M116 S3 ;wait for all temperatures to be within the default range of their setpoints (default 2C) set at 3C
G29 S1

my situation is i have a 350mm bed 10mm thick that takes ages to heat up say 4 min & that's with mains heating but my hotend heats up rapidly around 30 secs. i have worked out that the hotend will need equivalent of about 10 degc remaining on the bed to reach synchronised timing however i have it so the bed just heats up first as the hotend always overshoots 10 deg c at the start and i have to wait for it to cool down before it prints, just cant get the pid perfect on it with the auto calibrate system.

So if i used just m116 i am either cooking the filament which degrades it and can cause problems such as blockages as it sits there at full temp for 3.5 mins or i heat the bed then wait an extra 30 secs for the hotend which is time consuming if you already waiting for a whole heap of small proto type prints. better to spend that time setting up synchronised timing then waiting every time is how i see it.

but in saying that i like what you have done although adding the auto fill temps from the slicer would add the cherry on top e.g. S[first_layer_bed_temperature] & S[first_layer_temperature];

@T3P3Tony This is the error message i get before a print when i know the printer is already homed as the motors are still powered, this is after i have previously homed then printed:

@T3P3Tony Sweet Cheers for that.
With the object model key, how can i confirm the axis number, For instance i use a Voron where i have 4x Z axis motors, and in my config file i have:

M584 X0.5 Y0.4 Z0.0 E121.0 ; set drive mapping

Also where can i find info & references on other object model keys & Conditional g code?

2 situations for time saving

1: I would like to know how to set up the duet so i can time the heated bed and hot end so they are both ready at the same time.

2: I would like to know how to bypass all homing for printing after i have homed at least once without the motors turning off (Kept on reduced power to hold position)

Kind Regards
Scott

@jay_s_uk Thanks for the response, Is this possible or will be with a type 3 sensor as this is what i currently have?

I need to use a filament runout sensor on a different board to the extruder motor tool board as i am using a reverse bowden setup & go through a lot of spools. Having the runout sensor on the same board when you use a tool board doesn't allow for easy filament changes as the extruder can only auto retract a small amount & thereby would have to remove the bowden tube everytime, the solution is having the sensor as close as possible to the filament spool but this means it has to connect to the mainboard. I understand the precision is lost when done this way although, i don't need filament volumetric adjustments on the fly. I just need it to detect filament runout or lockup. Although There should also be an option for both incase one fails. etc. which i have experienced.

Toolboard v1.3

Voron 350

Anyone who shows me how to do this is muchly appreciated
