Re: PWM fan not working
Yes, but the PWM_FAN is controlled by another MOSFET. I think that is the issue. Or the AtMega2560 has an issue with it's PWM. Is that possible? In that case, board needs to be replaced. Right?

Re: PWM fan not working
Hi William, I think it is an AP2302AGN. At least according to the schematics and the way it looks like. It will be a tough soldering for me.

Re: PWM fan not working
Hi, I did some measurements and it appears to be that the voltage between those 2 pins is always 0, no matter what the fan speed is set. I have connected LEDs via another MOSFET module and they are always on. Do I have a faulty MOSFET? If yes, what can I do? Here is some more information: I use LED ...

Re: Upgrade ProB into a Dual Extruder Model
I am also currently interested in this. I am trying to do the same thing. As many users want to just upgrade to dual extruder, it would be great to buy one more extruder to upgrade. Basically, second extruder on the dual extruder is mirrored version. Actually, the stepper motor, fans and the heat si...

Re: 3d touch sensor g-code and endstop issues
I think I missed the first one at my first try.

Re: 3d touch sensor g-code and endstop issues
Of course, I can't really track back to the original issue but I assume it was a combination of a temporary sensor fail which led me to think that I was using the wrong ping number, because of the bad formatting in the wiki page of the pins.h code. So the pin was always doing a proper self test with...

Re: 3D Touch Calibration - Can't move to negative Z position
Of course, sorry for missing that. I have Prusa i3 Pro W. I have managed to improvise it by setting current Z value from 0 to 3. Then I was able to move down. Let's say until 0,4. So I set the M851 Z-2.6. Wiki document assumes that you can go to negative Z positions, which wasn't the case for my pru...

3D Touch Calibration - Can't move to negative Z position
Hi, I am trying to calibrate my 3D touch sensor, however I am stuck at the step, where I am supposed to manually move nozzle closer to the bed, until a folded paper barely fits in between. The problem is, that I can move Z to negative numbers. It stops at 0. Wiki page doesn't say anything about this...

Re: 3d touch sensor g-code and endstop issues
Thanks a lot! I think I now have solved it for myself. Due to different configurations I have seen around, I never got the correct combination of settings. Now it works.
