Official Marlin Support

A project log for Lerdge 3d Printer Mainboard Hacking

Breaking the encryption on the Lerdge series mainboards so I can try porting Marlin 2.0 to it.

Today the official build support for Lerdge X, K, and S was merged into Marlin's bug fix branch. LCD Support is still coming but I published a branch which combines LCD, Lerdge, and the upgraded STM32 core for maximum goodness.

This project is nearly complete - what's left to wrap up is details of the K board's FRAM and RGB LEDs.

And then we move on...

Hi Mister Nelson,

What is the status of this project? Can I already load the Marlin firmware to my K-boards? And would the LERDGE display work?
I would like to improve my Delta printers movements etcetera. LERDGE is not giving any useful support in that matter.

Hey there.

Is it hard to  adapt marlin fw for this board to another stm32F4? To be exact,I have MKS Robin2 (stm32f407zet6). Scheme with pinout is available, fw encryption was hacked by jmz52.
