Duet3 - New IDEX Setup

BlueDust

I am trying to get 2 tools working on my Duet3 board, and as of now, think I have a slicer problem. I am currently trying to get ideaMaker to work, and everything "appears" to work, but am getting an error for a GCODE command that doesn't exist on the Duet....

M605

I have read a few other posts on here about M605, but (may have just missed it) didn't see anything that would tell me how to fix it.

I know this isn't a ideaMaker support forum, but not only am I not sure how to get ideaMaker to send properly supported commands to the Duet, I am also not sure what the correct GCODE command is or how it should look when sent to the Duet.

Thanks!

So... Please tell me if I am wrong... To use 2 print heads, I will have to create a 3rd tool, and print to that tool. If so, that sounds like it will only work in copy mode, but not in mirror.

M563 P2 D0:1 H1:2 X0:3 F1:1 ; tool 2 uses both extruders and hot end heaters, maps X to both X and U, and uses both print cooling fans
G10 P2 X50 Y0 U-50 S0 R0    ; set tool offsets and temperatures for tool 2
M567 P2 E1:1 ; set mix ratio 100% on both extruders
M568 P2 S1 ; turn on mixing for tool 2

From my understanding M605 isn't used because you can get the functions needed with M563 when defining the tool.

https://reprap.org/wiki/G-code#M605:_Set_dual_x-carriage_movement_mode

https://duet3d.dozuki.com/Wiki/Gcode#Section_M563_Define_or_remove_a_tool

Remember that you can define your tools on the fly, so using a "3rd" tool that allows for duplicate printing with both heads at the same time is just a matter of defining the tool with the extruders, heaters, fans etc from both tools together in one.

Maybe this post gives some insight: https://forum.duet3d.com/topic/20105/config-idex-duplicate-mode-m563-error

You don't need any M605 commands. I've read of other users using Ideamaker, is there a way to configure it such that it outputs RRF, rather than Marlin, etc, if its not configured that way?

I hold the opinion (best practice?) that you should not be having a slicer define a M563 (or M605?), and instead call the appropriate tool. Have the slicer "simply" select/use T2, and then you should be good to go (based on the M563 you have defined in config.g).

Sorry for not getting back to this as quickly as I planned... I still need to get this working but ran into some other issues while trying calibrate the printer.

Thanks for the feedback. I will get back to trying to get IDEX working as soon as I can sort this out and get the printer, printing without confusing me during calibration prints. I don't want this sort of thing to occur while both hotends are printing... I will be even more confused if trying to troubleshoot something.
