@yoshimitsuspeed please post your tool change macro files.

Also have a look at the release notes between 3.3. and 3.4.5, there might be something that has changed that impacts this, if so then worth an upgrade.

[yoshimitsuspeed]

Alright coming back to this.
I just installed 3.45 firmware but haven't tried printing yet. Will start in a minute.
The highest priority right now is the fact that I don't seem to be able to adjust extrusion factors for extruder 0 and extruder 1 independently when tool 2 (IDEX duplicate) mode is printing.
This is causing big issues like for example right now running a spool of TPU at 1.74 and one at 1.71.
I am not expecting the firmware update to affect this but will see shortly.
Beyond that is this just a firmware setting I need to change or what?

Confirmed adjusting extruder 0 or extruder 1 extrusion factor has no impact on extrusion in tool 2 IDEX duplicate mode.

Heating issue
Tool 0 is left print head.
Tool 1 is right print head.
Tool 2 is IDEX duplicate.

If I set it to tool 2 before starting a print the machine crashes.
I set tool 0 to standby, tool 1 to active. Set tool 0 and tool 1 active and standby temps to 220. Both heaters go to temp.

Upload file to print.
Tool 1 active temp changes to first layer temp (240) and starts heating up.
Tool 0 active temp does not change and current temp stays at 220 until I manually set tool 2, heater 1 to 240.

First layer prints
Second layer temp changes tool 2 heater 1 and heater 2 temp to 250.

TLDR the first layer temp sets tool 1 temp only, but second layer temp changes both tool 2 temps properly.

[yoshimitsuspeed]

Nozzle temps
I think I cut out the first layer change in the gcode above.

It does seem Prusa is calling out M104 for the first layer temp and then G10 S250 P2 ; set temperature for second layer temp. Is this an issue in Prusa or in firmware?

Issue 1
I currently have a duplicate mode set up as tool 2 with offset extruders. So tool 0 is left print head, tool 1 the right print head, and tool 2 as the duplicate mode.
In Prusa this is set as extruder 3.
When trying to start a print with extruder 3 selected If I have tool 0 or tool 1 selected in the web interface when I start a print it will home properly, position both print heads properly offset and start printing in duplicate mode properly.
If however tool 2 is already selected when I start the print it will home and then both extruders will stay at their home position and then try to print from there.

So to confirm when T2 is in print start gcode, and T2 is not selected, then the correct behaviour happens:

@yoshimitsuspeed said in Optimizing IDEX machine and Prusa Slicer:

;TYPE:Custom
....
G28 ; home all axes
....
T2
; Filament gcode
....

so the order the print start gcode is boing things is homing the printer, and then calling the tool change. (which you say works) however if there is just the home, with no tool change (because T2 is already selected) then it does not work?

I think you need to take a step back and check your homing files and tool change files actually do what you expect before trying to print. So try all the combinations of tool selected and homing.

Its been a long time since i have used an IDEX machine however I suggest that you can simply this by always deselecting any tools and then homing (T-1 at the start of all the homing files). Mark some known points on the machine and then home, select T0, move th the co-ordinates of the point and ensure T0 gets there. Then home, select T1 and do the same. For T2 the nozzles should be equidistant from the point, the set offset between them.

[T3P3Tony]

@yoshimitsuspeed we can take the issues one by one.

[yoshimitsuspeed]

Okay so I did solve the extruder heating issue by replacing M104 with M568.
I haven't had time to mess with the issue when starting with tool 2 selected however as I said above right now the most important issue is not being able to independently control extruder rate when tool 2 is selected.
For example right now I have one spool of TPU that is 1.73 and another that is 1.76 and since I can't control the extrusion rate independently I have under extrusion on one part, and over on the other.
If I get some time I might go through my other spools and try to find one that more closely matches but this is being a pretty big inconvenience to my production process right now.

[Phaedrux]

@yoshimitsuspeed said in Optimizing IDEX machine and Prusa Slicer:

Can you not setup a filament profile in PrusaSlicer for each?

[yoshimitsuspeed]

@Phaedrux
As far as I know Prusa does not support anything regarding IDEX or duplicate type printing.
I have made the recommendation in their Dev forum letting them know it would be super helpful if it would. Both for the advantages of being able to enter separate filament diameters for duplicate, as well as things like being able to use two different print and filament profiles for a support material, or if you wanted to do something like running a hard TPU on one print head that could print fast, and a soft TPU on the other that required slower settings.

But as of now as far as I know, no there is no support for this in Prusa.

[oliof]

@yoshimitsuspeed I havent tested this yet but you may be able to trick RRF by setting the mixing ratio to (1.75/1.74):(1.75/1.71) to get different effective flow rates.

[yoshimitsuspeed]

@oliof
I would be pretty disappointed if that is the best solution. Not only would it suck going into the firmware and calculating that every time I start a print but it also means I can't tweak on the fly.

I am very confused by how this all works out.
It seems like M568 overrides the extrusion factors sliders in the status panel which is nonsensical.

I also don't understand why it has the extruders defined in M563 telling it to use both extruders, yet only one drives without M567.

I just don't understand why there isn't a base option that allows both extruders to extrude the Gcode defined amount with the extrusion factor slider functioning normally. Locking the two together with M56 and disabling the extrusion factor seems redundant and overly complicated. If M563 says use both extruders why aren't both extruders just driven by the E Gcode by default?

And or if someone decide that M567 is the required way to achieve that then why would it override the extrusion adjustment sliders?
This makes no sense.

[oliof]

@yoshimitsuspeed hey, I was just proposing a hack, by no means do I think its a good solution for your problem. You can adjust mixing ratio on the fly though, so it would be possible to do it dynamically....

[dc42]

@yoshimitsuspeed said in Optimizing IDEX machine and Prusa Slicer:

Oh yeah issue 5
As far as I can tell with my current configuration and I think because of the M567 code on the duplicate mode it seems like I cannot adjust the extrusion factor of each tool separately. I would like to be able to do this for situations where say I have a spool of 1.73 filament and 1.77 filament and need to adjust extrusion independently. That 567 code was in the IDEX configuration I found.
Can I just remove that and if so will it run both extruders and allow me to adjust extrusion factor properly?

As well as changing the mix ratio using M567, you can adjust the extrusion factors independently using M221. See https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m221-set-extrude-factor-override-percentage in particular the D parameter. I expect it is this command that the extrusion factor sliders in DWC change, but I have not verified that. You may wish to try using M221 from the command console.

[yoshimitsuspeed]

@oliof
Sorry if my comment came across as unappreciative. I do appreciate input. It just seems like there should be better solutions integrated.
I wasn't thinking about being able to apply changes through the console while printing which would make it less awful but still doesn't make sense that this isn't better designed for this application.

[yoshimitsuspeed]

@dc42
Thanks for the input.
If M221 is in fact essentially the same as the sliders then it seems like it would not work either. I might play with it if I get a moment.

I guess if that like the sliders is overridden by M567 then I guess using M567 via the console would be the best current working solution?
In this case am I right in assuming that adding to my Gcode file, or typing in the console say M567 P2 E1.01:0.99 would be essentially the same as having the extrusion factor sliders set at E0 101% and E1 99% is that correct?

[oliof]

@yoshimitsuspeed of course, thete is a case to be made that you could change extrusion factor per filament in the slicer. But I wont be making that case since a) RRF is supoosed to have built in filament management facilities and b) being able to adjust things dynamically has saved prints of mine more than once.

[dc42]

@yoshimitsuspeed said in Optimizing IDEX machine and Prusa Slicer:

To calculate the required extrusion, assuming that the G1 command only has a single E value, RRF first applies the M567 mix ratio to get the requested extrusion on each extruder. Then, if the move is a normal printing move (not an extruder-only move) it multiplies those values by the extrusion factors set by M221. So M567 does not override M221.

Does this mean that M221 does something different than the sliders in the web interface do? Or is there something else preventing my extrusion sliders from functioning properly? Because if I move those while printing in duplicate mode IE tool 2 the sliders don't do anything. Or at least the don't give independent control. I haven't tried sliding both to the same setting at the same time to see if I could increase or decrease flow on both extruders at the same time but if I set one at 99 and one at 101, or if I set one at zero and the other at 200 there is no change in extrusion.
