  • Just replaced stock ended 3 mainboard with BigTreeTech skr mini e3 v2.0 and it started smoking from the back right corner. I’m beginning to think it’s a manufacturing issue. Any suggestions?

  • SKR E3 v2 and BL Touch z-axis issues
    After installing the controller and updating to the latest firmware.bin file for the controller from I was able to print a calibration cube sliced with PrusaSlicer 2.3.0 without issue.
    No, I'm homing the z axis using the BLTouch. Cabling looks like this as documented here
  • The mystery of the "linear advance lottery" of the 4.2.2 boards seems to finally have a satisfactory answer. Today I got my skr and removed my 4.2.2 and pulled the stepper heatsink and this is what I saw. All 4 drivers are tmc2209s. | 2021-04-01
    I guess it has the same incompatibility as the SKRs have, because Creality decided to swap some pins (see But I can't say for sure.

  • Firmware.cursor file is generated but SKR Mini 1.2 screen is just blue | 2021-03-29
    I used this tutorial for updating my 1.2's firmware when I installed a BL Touch on my Ender 3 Pro. I think you are not putting the correct file on your SD card. It should be named firmware.bin and should be the only file on the card. When you power off and back on your printer with the card in place, the firmware will write to your motherboard, then it changes the name of the fie to firmware.cur, which is a text copy of the current version the motherboard has just installed.

  • SKR MINI E3 v2.0 with creality bl touch 3.1
  • Any idea What set of wires to use for ender3 pro with skr mini e3 v2 ! The first pic is the wires that came with the bl touch but are way to short the rest are the 2 sets that came with the bltouch mount/BTT extension set.
    So then I would recommend looking at this page to determine which cable to use. I know that on the skr e3 the wiring of a a bltouch is different then the cable setting.
