M557 - S70 seems large compared to the bounds (098 to 98)? Can you do, say, M557 X-100:100 Y-100:100 S20? S70 is unusual
To use Mirror or Copy, your print file GCODE must select T2 or T3. You can use standard Cura, slice the file, and then replace all instances of Cura-created T0, (or even T1) with T2 or T3 so long as you take care in where you slice the object on the build plate. This is still tricky.
Do not use BCN3D Cura for Mirror/duplication mode (copy, etc) as BCN3D uses a custom version of Marlin. In their mirror/copy GCODE files, they send a custom GCODE command to tell the machine to mirror or copy. They also modify the area you can place models in their Cura software to ensure the machine does not crash.
I recommend solving one problem at a time.
First solve Bed leveling
Then solve Blower fans (these are the part cooling fans, not the heatsink fans correct?) -
@sebkritikel Thanks for the answer.
I really forgot to point out. I have one motor for each axle.
I read somewhere on the site that if I create an additional X axis, then I must also create a Y axis. maybe I was wrong.
Possibly the Z axis positioning sensor is incorrectly set but it works.
the bed rises up hits the extruder and falls down so we get point 0. I would also like to have the sensor check the entire bed for evenness.
You're right, the radiator blower is working properly.
blower fan printed parts does not start -
I also forgot to say that I decided to use positioning in the center of the bed -

No, you don't need to create an additional Y axis, unless you actually have two Y axes. A standard IDEX has one Y axis and two X axes. The second X axis in RRF is normally called the U axis.

Have you been able to run a full bed probing? G29? I think you need to change your M557, as you have your bounds set to a 196mm length for each axis, divided by 70mm spacing..... Or try -95 to 95, with a spacing of 19mm (S19). 70mm is too large I think, especially for your bed size, to give a good bed leveling result, excluding the fact it does not divide nicely into 196.

Hey. I'm new to 3D printers. but I want to create my own. body and kinimatics are. Can you help me set up the control board?
-
@sebkritikel No, I was unable to run a full bed probing. I don't quite understand how I can run this. for a start, I think that four points will be enough -95 and 95
-
@sergei I think on my example you and others can create your own project.

I think you will want a greater fidelity... but lets start with something that divides nicely into your bounds... For reference, on my IDEX machine I have "M557 X-220:160 Y-200:200 S20:25 ; define mesh grid" and many other times you will see folks with spacing of 20-25mm.

Simply put - what happens when you type and send G29 in the console? Can also click here:
Have you corrected the additional Y-axis comments DC42 brought up? You have your X-axis, which is the T0 (left I assume) hotend. You have the U-axis, which is the T1 (right I assume) hotend. You have one Y-axis - that is driven by only one motor correct? Should be "M584 X0 Y1 U3 Z2 E5:6 ; set drive mapping " correct?
Happy to help!

M557 X-98:98 Y-98:98 S20:25 ; Define mesh grid
I changed the G-code and now the mesh bed probes are working. all that remains is to adjust the speed and acceleration.The next problem is getting the printer to work in parallel and mirrored.
it is not clear to me where in cura should I indicate T1 T2 and T3?
Just in the starter G-Code? I think it's not very convenient to edit the parameters of the 3d printer every time -

The start GCODE is very important for me. Cura is not a perfect software, and has some quirks. Before the start GCODE, Cura actually calls the tool for the start of the print, see below - T0 is called before my start script
In my homeall.g, I actually need to deselect the current tool using T-1 P0, otherwise if I'm printing with T1, T2, etc, Cura tricks my machine into trying to Z probe with the wrong tool(s). I added the ;Ext_Sel line into my start GCODE, and then use the Post Processing Plugin to manually select the proper starting tool.
For specifically duplication and mirror modes, I have a SECOND post processing script to change all mentions of T0 or T1 to T2. This one is silly, but I do it instead of creating another tool/extruder in Cura. I slice it for T0 (typically), do my first search and replace script to change ;Ext_Sel to T2 (to specify the tool after my G28 in start GCODE), and then a second search and replace script to change T0 anywhere else to T2 (specifically the FIRST tool mention created by Cura before the start gcode is made, the section in blue from the notepad file a few pictures up).
If not using T2, it must say ";T2" instead of "T2" - or T3 for mirror, etc.I think there are better ways of doing some of that... unfortunately the Duet board and firmware is much smarter and more configurable than Cura....
-
I think a better option is to create a third "extruder" in Cura through the "Machine Settings" window, and selecting a sufficient X or Y nozzle offset to split the bed in half or so, leaving space for the Duet firmware to map the movement to the U-axis.
I have not tried this yet, but I think this would be much easier. An important note - my T2 offset is different than yours, I did not offset the X axis, and instead only offset the U axis. This suggestion with Cura might not work with how you have offset the X and U axis - more investigation needed.M563 P2 D0:1 H1:2 X0:3 ; tool 2 uses both extruders and hot end heaters, maps X to both X and U G10 P2 X0 Y0 U-263.5 S0 R0 ; set tool offsets and temperatures for tool 2Strike that, I hadn't actually selected T2 (Extruder 3) as the print tool. By adding Extruder 3 it split the buildplate for T0/T1, not just T2. When you select T2, it actually makes the entire print surface unusable - wtf Cura.
-
Getting closer, but still not quite right. Some funky stuff going on in the background w/Cura.
With "Origin at Center" the previously entered X offset applies starting at the origin... but only if tools T0 and T1 (extruder 1 and 2 in cura) are disabled. Whatever you enter - such as 100mm, is for only one direction, therefore the overall width would be 2x (200 mm for example).
However, any combination of having T0, T1 active, with T2 both active as well disabled, results in the right hand side available build surface being truncated by whatever the X offset is set to (loss of 100mm. If the offset was -100mm, it happens to the left side of the bed, as expected). I don't understand the reasoning why... If T2 is disabled, why is the offset being applied? Is Cura really assuming that T2 will always travel during printing (a single gantry/print head), and thus must limit that offset amount? I think that is shortsighted... but perhaps the alternative is as well. I just tried expanding the machine X total print width from 450mm to 650mm in Cura (double the X offset in T2) which solves the T0, T1, T2 combo issue, but then that totally messes up the T2 only print area. Stumped for now........

@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 -
@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?
-
@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?

Have you read https://duet3d.dozuki.com/Wiki/ConfiguringMultipleIndependentXcarriagesCartesian#Section_Configuring_tools and the section on tool changing after? If so, what do you think is missing?
Generally our documentation covers setting up the Duet to work as transparently as possible with slicing software. However, setting up the slicing software is beyond our control, with so many options, though we will try to support you to get it working. With Duet customers building a huge range of exotic and wildly different machines, we are not able to create documentation for every conceivable permutation.

And why are you against bcn3d Cura? it was designed specifically for IDEX printerCura is complex software, and has the capacity to create machine profiles for your customers to use. Have you tried creating a machine profile, extruder profiles, and print settings to match the capabilities of your machine? You can post on their forums for help potentially on creating Cura profiles for mirror/duplication mode, as that is more specific to Cura than Duet.
https://github.com/Ultimaker/Cura/wiki/Adding-new-machine-profiles-to-Cura
https://github.com/Ultimaker/Cura/wiki/Definition-Files-Explained
Example: https://github.com/Ultimaker/Cura/blob/master/resources/definitions/ultimaker_original.def.jsonFor my IDEX machine, I have been (slowly) creating the appropriate Cura definition files, and hope to one day make it seamlessly work with mirror and duplication modes, but I am not there yet.
The Duet electronics hardware, RepRapFirmware, and community here are excellent at creating machines with intricate macros, amazing kinematics - but some effort is on the individual 3D printer designer to put all of the final touches in place.
You can certainly experiment with the BCN3D Cura, but keep in mind a few things.
- It is a "fork" of a much older version of Ultimaker Cura
- It is designed for use with their custom version of the Marlin Firmware, not RepRapFirmware
https://github.com/BCN3D
https://github.com/BCN3D/Marlin
https://github.com/BCN3D/BCN3DSigmax-FirmwareHere is the start of a GCODE file made by BCN3D Cura for mirror mode. Marlin GCODE

Is how the BCN3D printers know to switch to Mirror or duplication mode, however that is a custom command created by BCN3D, and not used in any other printer.
As far as additional hardware help - happy to be of assistance, however I do not know exactly how items like your fans are wired, what steps you have tried to troubleshoot problem areas, etc.

@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.
