@dc42 Is there really no way to change the automatically generated initial g-code? I think many motherboard duo owners would be interested in using bcn3d kura for their 3D printers

@sebkritikel
maybe there is some G-code that overrides the previous commands?

@sebkritikel
Yes, you are right there is one file that describes the sequence of our printer
C:\Program Files\BCN3D Cura 3.2\resources\definitions
File fdmprinter.def

"print_mode_gcode":
{
"label": "Print Mode GCode",
"description": "GCode to enable selected print mode.",
"type": "enum",
"options":
{
"": "Regular",
"M605 S6 ;enable mirror mode": "Mirror",
"M605 S5 ;enable duplication mode": "Duplication"
},
"default_value": "",
"value": "'' if print_mode == 'regular' else 'M605 S6 ;enable mirror mode' if print_mode == 'mirror' else 'M605 S5 ;enable duplication mode'",
"enabled": false,
"settable_per_extruder": false,
"comments": "BCN3D setting"

in the next line I found commands that surrender for mirror and parallel modes in Marlin and replaced them with T2 and T3

                    "T3     ;enable mirror mode": "Mirror",
                    "T2      ;enable duplication mode": "Duplication"

now when mirror mode is selected, g-code is configured with the correct T3 code without post processing.

But I just can't find those commands that add unnecessary commands at the beginning of the g-code.

Technical support bcn3d Sorry, refuses to help(((

@sebkritikel which firmware version do you use in your printer? could you share yours with me
tpost.g, tfree.g and Tools?

@dc42 The malfunction message does not appear. Only reports that extruder 1 has a low temperature.

@dc42 Yes, there is still room for play, but now there is another problem. heating does not work 2 extruder. after printing several layers, the heater of the First extruder turns off

also i noticed the following:
when you select mirror or duplicate mode, only the heater 1 of the extruder is turned on, then printing starts. 2 extruder stays cold. then after several printed layers, 1 extruder stops heating and printing continues with cold extruders.
I think that the error is that I used the instructions for creating an idex 3D printer for RRF 2.0 firmware

@dc42 said in Creating a new IDEX 3D Printer with Duet 2 WIFI:

Your tool offsets for T2 and T3 are wrong. You should have equal but opposite X and U offsets in the G10 commands. For example if the lower limit printable by the X tool is -150 then the X offset should be half of that, so -75. Likewise the U offset should be half the maximum positive printable U value, which in this example would be half of +150.

So I did at the beginning. but when using bcn3d slicer i had to adjust my firmware.
I myself move my model sideways from the center.
I am not saying that this is correct, but at least it works
This is now set up so that the two extruders do not touch each other while running.

In these settings, I selected the correct value and both extruders take their desired position.

@dc42 Yes, I adjusted the center of the bed everywhere.

@sebkritikel I understand you well, the cura slicer is constantly updated and new features appear in it. Unfortunately, this method is not entirely convenient for ordinary consumers. the bcn3d slicer is much better for these purposes, since in it you can directly see the process of creating a duplicate and mirror copy.

Unfortunately, the bcn3d technical support did not provide me with a solution for my printer, they offered me to use the Marlin software with which I do not agree at the moment as I want to use the duet motherboard.
I even managed to fix the work of this slicer to some extent. when choosing duplicate mode it adds M605 S5 when choosing mirror M605 S6. using post processing - find and replace I was able to fix it on T2 or T3.


As for the kinematics, everything works perfectly when selecting 1 extruder (command T0) the first extruder is running, the heater turns on, the cooling turns on and the process continues. when extruder 2 (T1) is selected, 2 extruders are used and everything works fine too.

but the following problems arose. when you select the duplicate or mirror mode, only one extruder heats up - left, but both extruders come in motion.

Most likely I made a mistake somewhere in the tools. Although I did absolutely as stated in the description.

@droftarts Well, of course I read this article but unfortunately it is for software 2.0 I'm using new software RRF3.0. also in this article it is not specified how to deal with g-code processing, that is, which slicer to use and how to configure it for an idex 3D printer.
Before I ask something I have been studying these questions for a long time on my own, but unfortunately it takes a lot of time and the answer is not always found.

@dc42 I also have one question. I am going to use Duet equipment in my invention and further replicate it, can I get support from the software developers in my printer settings?

@dc42 the developers of Duer3D and RepRap were able to create such complex software and nevertheless do not have detailed instructions for setting up an IDEX printer, the process of slicing, extruder selection, initial and final GCode, Slicer selection and much more are not described. Perhaps I missed something and such an instance exists?

@sebkritikel This is a rather complicated method. I do not think that a beginner and an ordinary consumer can handle it.
And why are you against bcn3d Cura? it was designed specifically for IDEX printer

I also changed set drive mapping

and added at the end Homeall.g and homez.g
