Runout Sensor for Voron and Universal

For my Voron I needed a simple filament sensor. Since the simple ones you can buy only have a metal strip to scan, there was always the problem after a runout that when the filament was pushed back it would get wedged in the sensor. So I made one that used a roller-operated micro switch. The original one is designed to mount to the back of a Voron which has a 3mm backboard and 3mm tape. To make it a little more universal, I have uploaded a version with a separate mounting distance, which you can simply use in the slicer in height.

In addition to the printed parts you will need:

1 Roller operated Microswitch, z.B. https://www.amazon.de/gp/product/B08734MSDD/ref=ppx_yo_dt_b_asin_image_o01_s00?ie=UTF8&psc=1

1 JST-XH, 2,54 male, z.B. https://www.amazon.de/gp/product/B082ZLYRRN/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

1 Pushfit M10x1, z.B. https://www.amazon.de/dp/B07BPVKT48/ref=sspa_dk_detail_5?psc=1&pd_rd_i=B07BPVKT48&pd_rd_w=azBmz&content-id=amzn1.sym.f63cb723-41a5-4d60-97aa-9969c9663073&pf_rd_p=f63cb723-41a5-4d60-97aa-9969c9663073&pf_rd_r=JSASPA4NQ0XPV5S7Y00J&pd_rd_wg=wp8D0&pd_rd_r=5a079f17-95d7-488d-9ddd-1f0e0128ce72&s=industrial&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWw∣=A1FELLZ9G9ZN36

2 self-tapping screws M2x10

I printed the whole thing in ASA carbon, but in principle you can also use PLA, PETG or whatever

Update: Added versions for transverse mounting and double-sided pushfit

Post-Printing =============

• After printing, it is recommended to clean the filament hole with a 2mm drill so that the filament slides through smoothly
• It is recommended to fix the JST connector with a drop of superglue before soldering
• I wired the switch as a "normally closed" contact, if you need a normally open contact then simply use a different pin.
• After assembly, check whether the switch is activated by the filament, if not you have to correct the roller bracket slightly. I have noticed that the switching points vary slightly on the linked switches
