Pwm on nidec ??
Does someone was able to get the pwm working on the nidec ?
I know that the pwm is the blue on the nidec . That the doc is totally misleading. I've followed the documentation on the 4028 form ratirig page .setup the jumper on 5v on cncfan , adjusted the name of the pin for the octopus wiring based on their shema.
I've adjusted the config and the wire so it doesn't blow at start or when the fan bar is at 0%. But as soon I add some percentage it full blow. It s like aon/ off for the moment?

Titl bed -issue with z-tilt
Hi guys,
I just finished building my VCore4 500 and I'm currently commissioning it, but I'm running into a lot of trouble. I was able to play around a bit, move the print head, and melt some PLA to test the extrusion and the filament sensor. However, since I tried the Z-tilt function, I've been having issues. It stopped during the first attempts, saying that the value was increasing instead of decreasing. Now, whenever I try to home the Z-axis, it tilts like crazy and makes a lot of noise on the affected stepper motor.
Where is the Z-tilt data stored? How can I reset it? Even if I relaunch the process, it always starts with a HOME XY and then tilts again. I tried removing the Z-tilt section from the printer.cfg, but the issue persists. It was working fine before I attempted the Z-tilt function.
Another question: Does the BEACON_INITIAL_CALIBRATION require physical contact with the Beacon probe for the Z-offset? I ask because I lost the extended UHF screw (stupid mistake), so I used the nozzle to trigger the contact. I know this setup won't allow proper printing since the nozzle ends up too far from the bed.(I wait an extension replacment and a new full hotend to be sure)
