More troubles with a runout detector
Hi Gang
Im having trouble with my btt v 2.0 runout sensor. it triggers all the time.
here's what I have so far:
[filament_switch_sensor switch_sensor]
switch_pin: PG12
pause_on_runout: False
runout_gcode:
PAUSE # [pause_resume] is required in printer.cfg
M117 Filament switch runout
insert_gcode:
M117 Filament switch inserted
[filament_motion_sensor encoder_sensor]
switch_pin: PG13
detection_length: 3.5
extruder: extruder
pause_on_runout: False
runout_gcode:
PAUSE # [pause_resume] is required in printer.cfg
M117 Filament encoder runout
insert_gcode:
M117 Filament encoder inserted
I've tried putting the ^ in front of the pins. both sensors are triggering. I have a feeling i'm missing something obvious...
I just queried the sensors and they say:
8:11 AM Filament Sensor switch_sensor: filament not detected
8:11 AM QUERY_FILAMENT_SENSOR sensor=switch_sensor
8:10 AM Filament Sensor encoder_sensor: filament detected
8:10 AM QUERY_FILAMENT_SENSOR sensor=encoder_sensor
So it looks like as of this moment the encoder is sensing a filament but the switch (which I think would be easier) is NOT detected.
Also, since I'm not sure what I'm doing, exacly I added
SET_FILAMENT_SENSOR SENSOR=encoder_sensor ENABLE=1
SET_FILAMENT_SENSOR SENSOR=switch_sensor ENABLE=1
at the beginning of all my prints...
Can anyone help me untangle?

XY matches, but....not tight enough? maybe?

Newly created 400x400 here. i just printed a calibration cube. First layer is perfect, no trouble there. What im experiencing though is the sides of the cube are slanted. its not a 90 degree angle. maybe 89 degrees. its quite noticable. If i take a square along the side "Y" side or the "X" side, I can see its not square. What can i adjust? ideas? I've done a belt tensioning...and after adjustment, my mesh shows i'm now within .18...
suggestions?

4028 Fan weirdness
#fix-my-printer
Bit of strangeness around my Delta FFB0412UHN 4-pin 12V 4028 fan. Its hooked up as documented here: https://os.ratrig.com/docs/guides/4028 It mostly works. 0% fan is off, 100% is jet engine. So far so good. But there are some strange things
1) It doesn't seem to come on until the percentage is about 7%.
2) the RPM (wired to PD14 ) is wierd. at 0%, its 0 rpm. at 50% its about 12000 RPM. But then it seems to DECREASE. at 80% power, the reading shows about 900 RPM, even though the fan is spinning WAY faster.
Also really odd is that the ratrig article says that for delta fans, blue wire is PWM
But https://www.delta-fan.com/Download/Spec/FFB0412UHN-SP4Z.pdf claims that the YELLOW wire is PWM, where Blue if F00. That document also states that 25 Khz is correct, leading me to believe that a cycle_time of .00004 is indeed correct.
My fan section reads:
[fan]
pin: !fan_part_cooling_pin
cycle_time: 0.00004
tachometer_pin: ^PD14
tachometer_poll_interval: 0.0005
Any suggestions? What kinds of parameters should i be looking at?

moving one axis
new build here. My first core xy. I haven't done the electronics yet but I did finish the mechanics. After tightening the belts I noticed that when I move the gantry in the x direction with my hand, both the x and y motors turn. Similarly when i manually move in the y drection, both belts turn.. Is this expected?.or did I mess something up?
