As title says. I got myself a filament runout sensor, wired it, designed and printed a holder for it and now I am experiencing some issues. I hope someone here can help me.
At first, the sensor is doing its job and seems to be working as it should. Printing is possible, but only with extra steps I would like to avoid. I use this sensor:
Creality Offiziell Filament Runout Sensor Kit Ender 3 Filament Erkennung Modul Detektor Gerät Original Pausen Erkennungs Monitor für Ender 3Pro, Ender 3 V2 mit 32 Bit V4.2.2/V4.2.7 Motherboard https://amzn.eu/d/3aR6o2e
I am using it on my standard Voxelab Aquila running Alex firmware. Slicing in Astroprint and managing over Octoprint on a raspberry pi.
The problem: The runout sensor sends a false positive right after starting a print. It draws the first line on the printbeds side and then stops telling me the filament ran out. It then proceeds to unload the filament and asks me to change it. I then re-insert the „new“ filament, it extrudes a load and then prints just fine.
So as you have possibly guessed right, I want it to print right away, just stopping the print, if there really is some jamming or no more filament left. Does someone know if I have to adjust the start commands or something like that? It seems to be a software problem.
Thanks in advance for any help!
Update: I gave up on this project and sent the sensor back. I couldn’t get it to work even after modifications to the firmware. Too bad…
I already tried that, didn’t work. I increased the runout distance and sent some M412 commands to configure everything before a test print. It then seemed to work, but when I cut the Filament to simulate a runout it didn’t work. Sending the sensor back if I can’t get it to run this weekend
