Marlin-2-0-x-Anycubic-i3-MEGA-S VS Marlin

You can try the marlin version from Knutwurst. https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S

I don't have the Pro, just the S - but just finished up installing a 3d touch about 5 minutes ago using this firmware and tutorial/wiki: https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S The guide also has the wiring / pins /etc.

I would recommend using https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S/releases firmware as its more up to date and has good documentation

The Knutwurst is here: GitHub Knutwurst

https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S You can download the already compiled version for the drivers you installed.

I followed the guide linked in this github page: https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S

If you print too fast, skipping is likely to occur. This is a separate issue from the firmware. It's also possible that the new firmware is causing an issue. What firmware are you using? There is only one firmware for this printer: https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S There is no other viable option!

Marlin FW (precompiled binaries): github.com/Desuuuu/Marlin/releases DWIN Screen Files: github.com/Desuuuu/DGUS-reloaded/releases Screen Instructions: github.com/Desuuuu/DGUS-reloaded/wiki/Flashing-the-firmware There are also config files if you want to compile that fork of Marlin: github.com/Desuuuu/Marlin

If you complied the firmware, and are using the stock board, I suggest that you check your conifguration.h against one from a similar (or same printer) to make sure that the bed size and endstop configs are correctly set (for example this one for the Desuuuu firmware https://github.com/Desuuuu/Marlin/blob/master/Marlin/Configuration.h). It may be simpler though to just try a pre-compiled fw like Tinymachines (make sure you get the BL Touch version) if you are using the stock board.

For people who don't want to replace the whole LCD screen, this fork should work with the stock screen. I haven't tested it myself though. You also need to flash firmware to the screen in addition to the board.

This year I started using an adapted version of the latest Marlin firmware (https://github.com/Desuuuu/Marlin). The touch screen works a lot better. I started printing and after a while still got the M999 error, carefully pulling the BLTouch probe somehow fixes this issue and I'm now able to use Simplify 3D, no idea if its related to slicer though since that doesn't make sense...
