VC4 Hybrid pauses at random ocasions after Orbiter 2 Smart Sensor was installed.
Hello! There are no error messages or other identifications that something is wrong, printer just pauses itself like the filament would be not present (green light is on), printhead is parked in the front of the machine.
I have assembled and configured it as per these instructions: https://docs.ratrig.com/v-core-4-0/orbiter-2-smart-sensor#Smart-Sensor_Build-Guide
Any ideas?

I will upload a debug.zip tomorrow
maybe you have some insights? 🙂 I will start a 10 days long printjob, filament sensor would be nice 😄
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.
I am pretty sure that's not the case. .. But idk what could be wrong here. Did you set up your sensor as per RatRig instructions?
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.
I find out that every few seconds my sensor blink yellow Led and pausing maybe its related to retraction and pretty loose bowden adapter?
If you enable the "enable debug" macro, you will see what is causing your printer to pause
i swapped my lower ptfe tub run to a bigger diameter. trying to decrease friction. similar like this mod https://www.printables.com/model/1125581-ratrig-v-core-4-6mm-ptfe-mod-reverse-bowden that helped mit so far.
