Input Voltage PWM fans not working
Its very strange, ive been browsing the forums and it would appear its happening more frequently as of recent. I doubt we are all making the mistake at the same time after the MCU´s working fine for a long time 🤷♂️

Input Voltage PWM fans not working
It happened one day after working fine for a year, I cant remember the event that caused it, I update regularly but i doubt that could be the casue.
New MCU fixed all my problems.

3.1 Suddenly 4028 Loses PWM control
Problem was a shorted MCU, explains the sudden failure after working for 1.5 years.
Replaced the MCU and the fan (just in case the PWM module was damaged) and now everything works fine 👍

4028 does not work
If it was working fine before until the incident while all cables and connectors have good continuity I don’t know what it could be other than that.
The only thing I can remember happening between the time of it working and not was a full system update, I don’t know what else to say 🤷♂️

I think it’s a problem with my MCU, pwm reads 22v across ground

4028 does not work
I’m not saying that it is, I’m just saying that in the last two months there has been an increase of this kind of support ticket.
Example with my case it was working fine for one and a half years until one day it did not so I doubt anything to do with being hooked up wrong 🤷♂️

4028 does not work
I can remember seeing 3 other posts in the last 2 months regarding this. Maybe it’s a software issue?
Mine used to work fine until one day I turned my printer on and am having the same issue as the OP

3.1 Suddenly 4028 Loses PWM control
Ok thank you! You really didn’t have to do that so I greatly appreciate it. I have a spear MCU so if your voltages are a lot lower then I will assume something is wrong with mine and I will install a new MCU

That’s what I thought, in the video you can see I have the GND positive and PWM going to the fan exposed for probing
