IDEX Setup Macro Issues

RogerPodacter

Looking for some help with a new IDEX printer. i had "some" success if i do not use the tpost.g macros, and simply add the following to my slicer custom Toolchange scripting:

{if layer_num>=1}; park the old extruder
{if previous_extruder==0}G0 X-70 {elsif previous_extruder==1}G0 X380{endif}
;change to the new
T{next_extruder}
;unpark it
{if next_extruder==0}G0 X-70{elsif next_extruder==1}G0 X380{endif}{endif}

However i dont prefer this method, and i would rather use the Duet macros. but when i use the following macros, i get various issues.

printing starts normally and the 1st layer completes, but then upon the first toolchange, the T0 crashes into the left side of the printer attempting to park.
after the crash recovers, then T0 moves back out approximately 100mm to the bed and parks.
, then tool T1 begins clicking extruder for about 10 seconds, where the gears just click and i can visibly see the gear clicking. at this time temperature is at proper printing 205C. finally the tool T1 moves over to the print area and begins printing normally.
switches back to T0, and T0 now begins clicking on the extruder. then T0 crashes into T1.

its very baffling to me. i have some success using only the slicer. but in Duet gcode i am struggling.

Here are my files:

@RogerPodacter Can you verify your firmware version?

Some notes

tfree0.g - You have G1 S2 ... 'S' is deprecated for this use type (instead use H2).
I don't think, for your use case, you need to have anything in your 'tpre' files. When calling a tool (say T0), tpre0 executes before tpost0. In this case you're asking the machine to move in a more negative direction (from -69, defined in tfree0, to -70, in tpre)

Comments above also apply to your tfree1.g and tpre1.g.

Looking at your gcode file - I don't see a tool called prior to you purge line, is that correct? It appears as if you set some temperatures, home all axes, set temperatures again, prime 'a' nozzle, and then select your initial tool. Can you also post your homeall.g? My recommendation for a start of print file is to set temperatures, home each axis (it may make sense to deselect all tools during homeall.g), select your initial tool, prime the nozzle, and then start printing. It seems that your print file is not selecting a tool until the model is about to begin.

It looks like you're setting the active/standby temperatures for T0 using the M568 command, but I don't see one for T1. I may be missing something based on other macros you're calling early in the print file.

@RogerPodacter said in IDEX Setup Macro Issues:

, then tool T1 begins clicking extruder for about 10 seconds, where the gears just click and i can visibly see the gear clicking. at this time temperature is at proper printing 205C

Are you saying that, while the T1 temperature is at 205C and parked, when it executes the tpost1.g G1 E6 F900, the extruder is not working properly?

Here are my tpre, tpost, and tfree for T0 on my IDEX machine

@sebkritikel thanks, i am working on your suggestions. to answer some questions, yes, both extruders function normally and extrude ok. but for whatever reason, those macros suddenly make both extruders have a clicking gear turn for about 10 seconds each. temperatures are correct etc so its something wrong with my macros.

EDIT: I am on firmware v3.4.2 on the Duet 3 Mini 5+ and also on 1LC toolboards 1 and 2.

here is my homeall.g.

ok so after i made all changes the behavior did the exact same thing with the following new files. literally same behavior in the same order.

@RogerPodacter Hmmm right now I'm not seeing anything stick out to me. The gcode file looks mostly fine now, and the T0/T1 sections all look expected to me (it does look like in the new gcode file T0 is used to print both calibration set's first layers, but that shouldn't be causing tool changing issues).

Any chance you can try and upload a video or two of the tool changing behavior using the above print file and tool change files?

If, without a print running, if you select T0, jog it to the center of the machine, and then select T1 - what happens? Same for T1 - select it, jog to the machine center, and select T0 - what happens? Same behavior or different? Perhaps possible to upload quick videos of that as well?

Not a huge help, but here is how my machine responds after doing the above test for T0 - first run is from my posted files from earlier, second run I include restore points commands (copied from your tpost files).

@sebkritikel thanks this is a bit helpful.

if i start out and home all axes so all is good, then move Tool 0 to X100 mm within the bed area. if i then select T0 tool again to park it, it crashes into the left going to -100mm. almost as if it mirrored the coordinates.

Here is a video:
https://www.youtube.com/watch?v=veS7V6F3ttg

EDIT: i learned that if i remove the tfree0.g file, nothing at all happens when i change tools to T0. as soon as i add back tfree0.g, it crashes left into X-100mm.
Its related to G1 R2 store point, but i dont understand why or how.

sorry to spam this thread, but this likely seems like a bug in RRF, perhaps related to Dual Markforged IDEX kinematics.

for my last example above, when i start the X carriage at 100mm and deselect Tool 0, it crashes into the left at -100mm. but that is because i was also at Y100mm.

if i start out at X100 Y20, deselect Tool 0, the X carriage now crashes into the left to -20mm. it seems to be something related to the kinematics not properly compensating during an IDEX tool change. i could be wrong here but so far that's what i am seeing.

@RogerPodacter here are my Idex macros maybe that will help.

@Proschi78 thanks, i'm fairly confident now this is surely a bug. in your tfree0.g file the line where you park the carriage G1 U400 F6000 ; park the U carriage at +355mm, for some reason the X and Y axes become "separated" or independent, and the U, X and Y axis dont compensate for each other during motion. this only happens during a tool change.

if i park my X and U carriage at any location during a tool change, the U carriage is not properly held in place as the X moves to some location. similarly when i was parking X and U and NOT specifying a Y coordinate, the axis somehow loses position and doesnt correct for the Y location. its really strange but thats the best description i can give.

perhaps i can get a better video.

I have no H2 in my file.

G1 H2 U379 F6000 ; park the U carriage

RogerPodacter

@Proschi78 thank you so much. removing that H2 seems to have fixed almost all of my issues. damn. let me try running some tests and see how this is working.

Hope it fixes it! Its been a second since I reviewed the why for the H2 in my files, but I could see how in a CoreXYish/Markforged that would mess you up FWIW I use the more Cartesian IDEX approach - I'll have to keep an eye out for differences like that in the future. Some similar discussion on 'H2' here: https://forum.duet3d.com/topic/29180/possible-bug-observed-after-v3-3-to-3-4-1-update/5?_=1672696734502

Glad someone was able to find the issue!

@sebkritikel I think the H2 command is to be used to move axes that are not homed.

Correct, it's normally used only in homing files and for testing purposes.
