Orbiter Sensor / Ratos MCU error after loading filament and Resume

I have a orbiter 2 with filament sensor, configured as per attached printer.cfg on a EBB36. This used to operate with the OrbiterSensor.cfg but this is very complex so I changed it acc. to Helge's suggestion in another post (adopting the Pins to the setup with EBB36). One change that I had to make between the 2 configs is that I had to inverse the functions (remove the exclamation marks) and added the ^ sign as per suggestion of Helge. - Pressing the unload butten works - Sensor activates the Park & unload sequence during a print. 2 issues remain however - Minor issue: When I pull out the last filament-bit out of the extruder, the extruder immediately starts the Load Filament routine. I quickly put the new filament in and it then continues loading and purging and waits for me to press the resume button. - Bigger issue: after pressing resume, it briefly moves the extruder towards the resume point, the halts and throws an error: 10:11 FIRMWARE_RESTART 10:11 MCU 'mcu' shutdown: Rescheduled timer in the past 10:11 MCU 'mcu' shutdown: Rescheduled timer in the past This generally occurs when the micro-controller has been requested to step at a rate higher than it is capable of obtaining. Once the underlying issue is corrected, use the "FIRMWARE_RESTART" command to reset the firmware, reload the config, and restart the host software. Printer is shutdown 10:11 Klipper state: Shutdown 10:11 Filament loaded! 10:10 Filament unloaded! Please inspect the tip of the filament before reloading. 10:10 SET_FILAMENT_SENSOR SENSOR=filament_sensor ENABLE=1 Printer: RatRig VCore 3.1 300 (Enclosed) Manta M8P with CM4 + EBB36 Orbiter 2.0 with filament sensor Revo Voron Printer.cfg + klippy.log attached (I will add @ of Helge later this evening, not to ping him now as per his request)

@Helge Keck Ping (assume now is evening as I do not know your timezone,... forgot about this "global" thing called internet...)

hmm, i dont know any of your hardware,. neve rused the manta, cm4 nor the ebb36 i see taht you jsut call the ratos load and unlaod macros i cant explain what happens you could try another gpio pins for the sensor avoid endstop pins use normal GPIO pins

Ah,. ok,.. Ill look into it tomorrow... (need to earn what Endstop pins are and GPIO pins are on the EBB36 but that should not be a big issue. Google's my friend). Thanx for looking into it. @Helge Keck switched to the EBB42. I had the sensor on the EBB36 on the I2c pins. Now I have the same on the EBB42. are those normal GPIO pins?
