Re fans, it's understandable they don't stop until drivers are disabled, after all they draw current just to hold a position but even so, the code should allow dropping the fan speed. The sample code appears to suggest this is how things work but in fact the code only works after M84 (Disable...

I'm printing right now so can't test, you could try: max_power: 1.0 #0.5 # max speed 100% might be too loud for these fans unless dampened (may change for quieter fans later)... kick_start_time: 0.5 # full speed for x to make sure fan spins...

I have noticed that too, I tend to home all and wait 30 seconds before the fans stop... It's almost like a specific action is required before timer times out... I'm guessing it kilpper firmware issue, I'm hoping it's fixed in the future as that is what the stated action should be... Been on...

The setting for turning fans off after x time is idle_timeout, but not sure if it is available any fan instance other than controller_fan... As an example I use: [controller_fan Motors_Fan] pin: PD15 # max_power: 1.0 #0.5 # max speed 100%...

That's the best approach, get it to work flawlessly first, then tinker... For currents, I choose run_current: 0.9, hold_current: 0.5 but I upped run_current to 1.0 recently to see if there was any difference but didn't notice any... BTW, I built with LDO Kit and (chaoticlab all metal CNC parts...

Making progress... down the road you could try sensor-less homing (2209's), it should provide a few more mm's on both X & Y, it also simplifies wiring...

Home the gantry and measure the tip of the nozzle to front, back and left, right, in theory they should be equal, in practice I would expect slight differences... These resulting measurements should tell us if the actual bed is centered but a little adjustment to the bed might be required...

Looks fine, I did a bit of searching and it appears other have had to modify the position_endstop to correct things For [stepper_y] try: position_min: 0 position_endstop: 310 # for 300x300 build position_max: 310 # for 300x300 build What settings have you got for home_xy_position?

I didn't use end-stops, I used virtual-endstops (sensor-less) so I'm not familiar but the documented defaults values for 300 are correct. I would imagine if the rotation_distance was incorrect it could result in travel errors but apart from that I'm lost. If config values are correct, swap x,y...

Double check distance from front of bed to outside front extrusion is 38mm...

Ideal: In a perfect world, we would run the fans at speeds proportional to temperatures, only running full speed when entirely necessary, otherwise run at about 20% to keep everything quiet. If you could map speeds to temperatures that would be ideal, but the best we can do is ramp up if...

Extra Fans As the skirt will accommodate two additional 60mm fans, I purchased and installed two NF-A6x25 FLX fans. Needless to say they are quiet, very quiet... It's time to update the default 60mm fans... I should add, I've gone from noisy to quiet with a few simple changes to fan speeds and...

My exact thoughts, I believe a keyed version exists, I'm sure I saw one previously, exact pin count and pitch... I did scope the signal, a schmitt trigger is definitely required... As there's a the 100 ohm limiting resistor, the buffer must source, but even so, 20-30mA should be enough for...

I checked the board and the leds four times, no shorts... besides, it has a 100Ω resistor on the output, that would pretty much prevent blowing the device (assuming a if 5V supply), also, the third board worked perfectly and is still working. The only way I see to cause this damage is if I...

Here we go... Blistered IC... Component fell off this one, it was not damaged or marked, the damage is from my poor attempt to re-seat the component with poor eyesight and no optics. I do have the necessary equipment (trinocular microscope) but no room to set it up and I am a pretty good...
