Hey guys! Just fully assembled the Proforge 2S kit. Now I'm facing various problems.
Maybe you have tipps or ideas what could be the problem :-) 1) Extruder #1 doesn't heat a single degree, error after ~30s. Powersupply delivers 24V, Thermistor shows 26°C. Extruder #2 reached ~150°C before getting an Error. 2) Difference in measured room temperature between extruder 1 and 2 of 7°C
3) Switching heads stopped working after a few tries
4) Autoleveling randomly stops working - one time it gets the whole bed done, on other tries it gets errors
5) When moving to the front left corner to the autoleveling position the Y-axis makes strange noises
6) Touchscreen doesn't always react if you try to move axis
7) After the slightest error you have to repower the printer before you can do anything.
I guess that was the troubles for the first shot. Hope that is fixable and that there are not more errors.
Thanks in advance!

1 : Check the wires
3 : Stop using it before change the code for servo otherwise it will break the servo
check Makertech ForumHome -> Assembly -> Servo not switching properly from Chris D
4, 5 : check the platform position
DSE: If you're building with the Dual Switching Extruder, mount the platform 75mm from the left of the extrusion.
That's all I know so far, Good luck to you.
Wireing should be fine, doublechecked it according to the manual. Also I can't imagine how the temperature difference between the thermistors could be related to the wiring. Was my first guess to I have to admit. Thanks for linking the thread! Only curious thing is that it worked and from one restart to the other it stopped moving the servo and only moved z-axis a bit.
Fixed as far as I can see. Buildplate is a bit wobbly, guess that needs a bit of tightening and playing around with the excentric spacers. Thanks for reaching out @itsmejun ! best regards

i have the same thing a big pile of door stop. the switching servo died after a few tries .never ever got aany kind of print out of it.worse 1000 bucks i got burned for yet.so i ended up buing a prusa.now that's a great 3d printer
Hi Michael,
Sorry to hear you're having these issue, we're here to help and send replacement parts if need be!
In addition to what itsmejun has mentioned it sounds like you may have a bad control board/thermistors that's causing the errors.
We can get replacements sent out, I've just emailed you now.

Hey guys,
Where should the plug/Pins from the probe go? The replacement is a 2.0 Version of the MKS, the old was a 1.0. The layout is different, connecting the probe to Z-Min does not work. Where should the blue and the black wire go? Does it work with the actual Firmware?
Thanks in advance!

I’ve attached schematics of both versions of the board for your reference.
So, the blue cable needs to be fixed to a ground pin on the v2 board and the black cable needs to go to a digital pin on the board.
Originally this was GND|D63.
On the v2 board you can make this D32|(5V)|GND (bottom right of board).
Obviously here you will need to move the crimps in the cables housing appropriately to match and avoid plugging into 5v.
Once the wiring is sorted you will need to update the firmware and let it know the new digital pin number for the probe.
This is done in the pins_RAMPS.h file. You can open this in the Arduino ide or notepad++. The line that needs editing should be #78: #define Z_MIN_PIN 63. Swap the “63” for 32 to correspond to the probes new position on the board.
If you find any error doing this, repeat this process with a different digital pin.
Any problems, please let me know.
