Hi there,
I’ve got a need to extrude filament with heater being OFF but whenever I try to do so I get the following:
“Max31865 Overvoltage or undervoltage fault
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”
In order to extrude filament I use the following command:
G1 E100 F300
I set both min_temp: 10 and min_temp: 10 to minimum in the extruder config section
and max_extrude_only_distance is set to 500.0 so it should work but it won’t. The extruder starts moving filament but then the firmware crashes immediately.
My extruder config is show down below:
[extruder]
step_pin: PE2
dir_pin: PE3
enable_pin: !PD4
## Update value below when you perform extruder calibration
## If you ask for 100mm of filament, but in reality it is 98mm:
## rotation_distance = <previous_rotation_distance> * <actual_extrude_distance> / 100
## 22.6789511 is a good starting point
rotation_distance: 22.6789511 #Bondtech 5mm Drive Gears
## Update Gear Ratio depending on your Extruder Type
## Use 50:17 for Afterburner/Clockwork (BMG Gear Ratio)
## Use 80:20 for M4, M3.1
gear_ratio: 50:17 #BMG Gear Ratio
microsteps: 16
full_steps_per_rotation: 200 #200 for 1.8 degree, 400 for 0.9 degree

## Try to keep pressure_advance below 1.0

## Default is 0.040, leave stock

Is this a bug?
Thanks.
