How to add a filament runout sensor on skr pro #127

Open LegendAlexander opened 4 years ago

LegendAlexander commented 4 years ago

I cant find any probe pins and i tried adding the sensor to the Xmax but it still wont act knowledge when filament is out. Actually i cant get the Xmax to trigger at all.

Aside from that i dont know where to remap the filament runout pin to since it seems there isnt one on the board.

I tried making this #Define Filament_Runout_Pin X_Max_Pin

Any ideas?

@legendalexander plug in an endstops 1st and see if the led light next to the E0 turns on. If it does the pin works you just have to find the right Marlin changes

i had the same problem today. i'm using a mechanical endstop as filament rounout sensor. the board has 3,3v on the vcc pins of the endstop connectors. when high the signal pin of the endstop only had 1.5v. although the endstop is labeld as 3-12v it does not work with 3,3v.

for x and y i'm using optical endstops, they work fine with 3,3v.

i ended up using the extension-2 connectors 5V, GND and PE4 pins:

you need to change the filament runout pin in pins_BTT_SKR_PRO_V1_1.h:

ifndef FIL_RUNOUT_PIN

define FIL_RUNOUT_PIN PE4

endif

Here is an SFS configuration that works for me 100% and we are entitled to a flashing E0_X_MAX_PIN LED.

The PE15 I want to use for filament run out but somehow is does not work. It is assigend correctly in pins.h and using using marlin bugfix 2.0.x and with tft35 v3 Any ideas? With the M119 command i see it is working correctly. https://to0wnn.com:5001/sharing/EmN4oMFoo Here are my configs
