Hi Jeffrey, when the end of the bolt hits the nyloc you will need to apply more force to take it 1cm up. Use a pair of pliers to hold the nut and then use an allen key to turn the bolt.

Check the polarity of the power cables from the heated bed to the MOSFET, you might have them the wrong way round.

When using with the DSE we recommend mounting to the other side of the platform to avoid a crash.

The Pi3B board is compatible but will require a USB WiFi dongle to connect to a network.

Try swapping the motor cables around and see if the problem changes motors.

I assume you have the printer connected to your computer via USB, there should be some LED’s on the board that come on when connected. Also try connecting directly to the board via USB.

Corrected, thanks!

First thing is to check the stepper drivers, always power down before making changes on the electronics board.

1. I assume firstly that you have fed the filament in through the filament sensor and there is a green light shining on the top of the sensor.

2. Check the sensor wiring is connected to the correct position on the touch screen. Shown in image 3 here.

3. If you download again the firmware for the touch screen and before putting it onto the SD card open mks_config.txt with a text editor like notepad++ (or Atom on Mac). Scroll down to the line 55: ">cfg_PB1_trigger_Level:0" and change the 0 to a 1: ">cfg_PB1_trigger_Level:1".

Save the text file and copy ONLY the text file to the SD card. Power off your printer, insert the SD card and power back on. This should resolve the problem.

Have you checked that you have connected them to the correct position on the board. When trying to power up the print fans from the touch screen you need to make sure that you are connected and powered from the mains too and not just the USB port.
