Fragen zum IDEX
Bei Mirror / Dupe bin ich jetzt nicht so drin (noch nie verwendet), aber ja da ist meines Wissens nach nur T0 relevant. Deswegen ist es sehr wichtig das beide Hotends exakt gleich lang, und die X Rail 100% gerade ist.

Fragen zum IDEX
Die Idee ist ganz nice, aber ganz ohne Support hätte ich dann doch etwas bedenken. Ich weiß nicht mehr wo ich das gesehen hatte, aber irgendjemand hatte das mal verglichen. Ohne Tube/Profil haben die IS Werte deutlich schlechter abgeschnitten. Aber hey... Bei IDEX wird dein IS mit hoher Wahrscheinlichkeit eh eine ziemliche Katastrophe sein 😆

Fragen zum IDEX
Hi,
1. RatOS nutzt nicht wie Stock klipper Z_OFFSET_APPLY_PROBE, wo der Offset in die printer.cfg per SAVE_CONFIG geschrieben wird. RatOS schreibt den Offset in die variables Datei und wendet diesen dann immer vor jeden Druck an.
Vorteil: Kein SAVE_CONFIG und Druckerneustart nötig + einfachere Verwendung wenn Sachen wie Thermal Expansion Compensation mit reinspielt.
2. Es gibt keine Grund für T1 ein Z-Offset einzustellen. Dafür ist der Z-Endstop da. Damit werden T0 und T1 abgeglichen. So wird ermittelt was für ein Abstand zwischen den Köpfen ist und das bei dem Toolchange entsprechend angewandt. (Auch während dem Druck im Z-Versatz Fenster in Mainsail sichtbar)
3. Der Wert wird wie oben beschrieben dann bei einem Toolchange angewandt.
Hast du den Drucker vor dem Start ordentlich durchgeheizt (heatsoak)?. Die X-Rail ist leider oben auf dem Profil drauf, was extreme Bimetalbiegung mit sich bringt. In wie weit Y auf 3030 Profilen betroffen ist kann ich nicht sagen, aber 2020 sind hier ein deutliches Problem. Habe ich auch diverse Tests damals auf meinem Voron gemacht.
Hier hilft nur 3. Sachen:
1. Seeeehr lange heatsoaken (teils Stunden)
2. Profil durch etwas tauschen mit ~ gleicher Ausdehnung wie Stahl (z.B Titantube)
3. Eine Rail auf die Gegenseite um den Bimetal Effekt auszugleichen.

IDEX XY Offset drift (VC4)
Have you been able to do any testing yet?
Im currently running a 1d print and already 17h in with no drift issues so far.

IDEX XY Offset drift (VC4)
Tried adding this to both toolheads. But it does not disable toolshift when its set to 0 as long as XYZ is provided. Not sure if this is how it should be.
When XYZ is set to the default it almost behaves as expected. For some reason Z does not travel up after a z hop (only purge tower)
Fixed it by adding to layer change gcode:
T{next_extruder}
G0 Z{layer_z} F1500 ;move down after z hop
[gcode_macro T0]
gcode:
{% set x = params.X|default(-1.0)|float %}
{% set y = params.Y|default(-1.0)|float %}
{% set z = params.Z|default(0.0)|float %}
{% set s = params.S|default(1)|int %}
{% if printer["gcode_macro _SELECT_TOOL"] is defined %}
_SELECT_TOOL T=0 X=-1 Y=-1 Z=0 TOOLSHIFT=0
{% endif %}131 replies

VC4 Hybrid pauses at random ocasions after Orbiter 2 Smart Sensor was installed.
Yes, there is no difference between the runout pause and the tangle detector pause. It is the same pin. The other wire is the load/unload button.
(and +/- wire, 4 in total)
This is really easy to find out. Start a print and set up a cam (handy or something) and film the printhead. If the orbiter sensor flashes orange before the pause its 100% your tangle sensor triggering. Immediately after the pause, it turns green again.

Is there an easy way to disable Toolshift? Maybe by disabling part of the post processor.
I want to try more complex/longer prints with toolshift disabled, but replacing stuff by hand (especially on larger files) is not a good/reliable solution.

IDEX XY Offset drift (VC4)
So its been some days. I again spend many hours trying stuff. Here a short list:
- I compledtly dissasembled my X Gantry. and realigned the Y linear rails. I think I got it pretty much as good as it gets, considering the rails have some resistance from the grease (see vid). It's a tiny bit better than before.
- I checked every single bearing and belt
- I completly disassebled both hotends and reasebled them. Changed the thermistor on T1 from Generic 3950 back to PT1000 (had a broken one)
- Switched out all umbilical wires to the toolhead and changed to a igus CF9 power wire.
Nothing of this changed anything regarding the issue. Idk what to try next.

VC4 Hybrid pauses at random ocasions after Orbiter 2 Smart Sensor was installed.
You may have too much friction in the PTFE tube and the orbiter sensor triggers. I also have this problem with certain filaments that don't slide smoothly in the tube. Maybe swapping the spring to a stiffer one would help.
The filament sensor and tangle sensor use the same pin. So when one is triggered, it will pause normally, as if the filament had run out.

Did you dried the PETG? Seems like a lot of stringing

I canceled the print because I could already see the drift. Since I already wasted ~2-3 kg for printing test towers I try to minimize the waste 😅

I have just finished printing with the other board. Still the same issue.
I think after swapping the psu, mainboard and drivers I can say its not an electronic problem.
Here is the debug.zip after the last test print.
