I found them running the latest beta.

The way I'm dealing with that is by defining a false axis (A in my case) with same parameters as E axis . Instead of retracting with G1 E30 you'll use G1 A30. That way you can have extruder movement without a tool selected.
You will also have to create a homeA.g file to home it - just need to have G92 A0 in it.

@bearer that looks easier than I was expecting it to be.
Basically I just send echo M300 S2000 P2000 > /dev/ttyACM0 , then ,for instance, echo G28 > /dev/tryACM0 to home it?

Yes, I’ll be using cron to schedule tasks.

This is unrelated to 3d printers in general and maybe unrelated to duet boards in general but helpful for a project of mine in which I’ll be using a duet wifi board. Maybe someone already does this and can help.

I want to send a certain gcode sequence to the board to be executed at a certain hour every day/ week et.

I understand I would need a raspberry pi or some other mean to send the code but I don’t know where to start . Ideally the board will be wired to the pi via usb because the board will be turned on before sending the gcode with a relay and sometimes the wifi doesn’t connect.

So my question is, how do I schedule sending gcode to duet?

Thanks.

@CanDo415 yes , my bad. You need to move in relative position with g91.
G1 U34 F500
G91 ;relative pos
G1 A+14 B+14 F3600
G1 A+1 B+1 F300
G90 ; absolute position

Probably you can do it without a homeA.g file by hiding the false axis using the P parameter in M584. then you'd have to unhide it each time you need to extrude without a tool using something like :

M584 P6 ;show the false axis
g92 A0 ; home the false axis
g1 a30 ; move the extruder
M584 p5 ;hide the false axis

Create the false axis using the two extruder drivers if using the same parameters on both (steps/mm) or two false axis ( A & B) and move them with G1 A30 B30

Is there a way to assign a filament to tools? Slicer side I have to use M702 M701 S"***" M703 every tool change, even if I have the same filament in two different tools for example.
Not a big deal, just a cosmetic issue, all 5 tools showing the loaded filament even if they're actually different ,the reason I have to "unload" the filament with M702 each tool change (load.g /unload.g in filament folder are empty) is to load different parameters specific to other filaments with M703.

Can't you just substract 20mm form your Axis maxima ?

I redid the wiring that way and it works now. I left both the positive and negative 12cm short.Thank you.

@Phaedrux Thank you
