#Filamatrix G2E Inconsistent reading on tool start

I'm trying to calibrate my extruder. The BT part seems to be working fine moving filament around, after some bowden friction issues that were resolved.

My toolhead setup is Dragon HF + Galileo2 and EBB (galileo2_extruder/ebbusb) so I run a single filament sensor (tool start)

I did change the hardware parameters to the recommended ones and sometimes T# command seems to change filament just fine, but mostly fails when unloading

pin_tool_start: EBBCan:gpio21
#pin_tool_end: None
tool_stn: 79                    # See documentation for details on how to calculate this value. https://armoredturtle.xyz/docs/afc-klipper-add-on/toolhead/calculation.html
tool_stn_unload: 100            # See documentation for details on how to calculate this value. https://armoredturtle.xyz/docs/afc-klipper-add-on/toolhead/calculation.html
tool_sensor_after_extruder: 0   # Extra distance to move in mm once pre/post sensors are clear. Useful for when only using post sensor, so this distance can be the amount to move to clear extruder gears
tool_unload_speed: 25           # Unload speed in mm/s when unloading toolhead. Default is 25mm/s.
tool_load_speed: 25```

I am running into the same problem. How did you get the sensor installed? I am having a hell of a time trying to get it set just right.

Edit: I finally figured out the install for the microswitch. I needed to remove the lever and have the ball bearing hit right at the switch.

So, G2E can work, it’s just very fickle and the tension needs to be just right. Overcoming the bearing and actually loading tends to be problematic.

#

The general recommendation has previously been to run CW2 instead

I've had so much problems with CW2 I really would like to stick with G2E. I've already disassembled my extruder and found that the ball bearing was not smoothly moving, so I applied a bit of acetone on a q-tip and I think it moves way more smoothly. I managed to load the filament once already, but I'm printing atm, I'll be testing loading tomorrow. I did reduce the extruder tension by a lot, so hopefully that will fix the issue

Not saying it can’t work, it’s just pretty fickle on how it needs to be adjusted to work correctly consistently. We’ve seen a lot of success with CW2 comparatively
