Duet3 config Frustration

BlueDust

I am still in the middle of printing parts (family project) but plan to get back to testing IDEX tonight.

@dc42
To keep wiring simple, I am now thinking about buying DUET 3 TOOL DISTRIBUTION BOARD and 2x DUET 3 TOOLBOARD 1LC. Is the CAN bus cable a standard RJ-11 telephone wire? Anything I should be concerned about if I make my own cable? Pins/wire order? (same order on both sides - straight through, or crossover, still looking in Wiki... )? Not sure if the boards come with cables...

Thanks!

I think the G1 S error was from pause.g

;Duet IDEX example Code
M83 ; relative extrusion
G1 E-2 F3600 ; retract 2mm
G91 ; relative movement
G1 Z2 F500 ; raise head 2mm
G90 ; absolute movement
G1 S2 X-52 U352 F6000 ; park both heads

That last line should have H2

Same thing in your tool change files. They are using S2 instead of H2.

Just to verify, are your tools motor and heaters defined correctly?

M563 P0 S"LeftExtruder" D0 H1 F0:1
G10 P0 X0 Y0 Z0                                    ; set tool 0 axis offsets
G10 P0 R0 S0                                       ; set initial tool 0 active and standby temperatures to 0C

M563 P1 X3 S"RightExtruder" D1 H0 F2:3 
G10 P1 U0 Y0 Z0
G10 P1 R0 S0

Drive 0 and heater 1 are paired and drive 1 and heater 0 are paired.

Otherwise I can't see anything glaring with your config files, though I'm not an IDEX user, so I'm not the best judge.

Thanks!
That code was copied directly from the Duet Wiki. I will fix it.
Thank you!

Yes. It is correct. When I manually move tool1 (right carriage), it moves. Also if I manually tell it to heat up, turn on part fans, (hotend fan turns on at 40c), and extrudes plastic, it does.

One thing I do not understand, is that if I have to setup a 3rd tool to have IDEX work and print in mirror, or copy (maybe a 4th tool?) modes? Or do I just set that up in the Slicer?
I had assumed, that was optiontional, where I could setup the Duet3 to always print in copy/mirror, or setup the slicer/Gcode for the model I am printing to do it as needed. And when I say to do this in the slicer, I don't mean add code in the beginning of the file. I mean to just tell the slicer to print mirror or copy, and then enable the 2nd tool (with settings for it's temp and when the cooling fan kicks in).
I am starting to assume my assumption was wrong.
Thanks!

I think that, given the length of this thread, and the fact your initial problems with Duet3 setup are largely resolved, it might be best to start a new thread focusing on IDEX setup and usage. Far more likely to draw some more knowledgeable eyes.

@Phaedrux

Sounds good!
Thanks!

@Phaedrux

I have made progress. I was able to get ideaMaker to print only on the 2nd tool. Not sure why it works now, but not complaining.
Now trying to figure out how to get IDEX working in copy and mirror mode.
I opened a new thread.
Thanks for the help!

I am trying to use the config tool, need some understanding of I/O Mapping tab. I am using Duet 3MB 6HC, and a Duet 3 Expansion 1XD for the external stepper driver. I have two questions

1.Meaning of filed options in Drives section-Endstop Pin [e.g io.in,io.in(active-low), io.in(pull-up), io.in(active-low,pull-up)] are not clear to me, what do they mean? , which is one to select? Similarly in the Heater section. Please refer to figure. Any documentation available on the config tool?

2.When I add the expansion board to I/O mapping, it adds Duet 3 Expansion 3HC by default, but I want to add Duet 3 Expansion 1XD. In this case, how can I use my Duet 3 Expansion 1XD board for my extenal stepper driver?

Also, I have 2 PT100 temperature sensor daughter boards stacked one over other, how can I add these additional daughter boards in the I/O mapping ? ?

@maddy Probably best to start a new thread for your questions rather than join onto someone else's older thread.

I think for the 1xd it might be a better idea to choose 1LC since that would be more similar since it's also a single driver board.

In the drop down list for the endstop at the end you'd see entries for the ports on the expansion board. The type you choose would depend on your endstop switch. Are they normally open, or normally closed, do they need a pullup or not? If in doubt, just choose the normal option and test and change to suit.

The wiring diagram will tell you what port is what.

You don't need to add anything special for the PT100 daughterboard, just choose the PT100 option from the sensor drop downs.
