Easy! We just want an open firmware for the Anet ET4 due the limitations of the original one it's imposible to improve the printer or correct/modify any kind of parameters.

We love ours ET4s but we need URGENTLY an open firmware.

For example: adjust the PID, change motor`s steps, replace the extruder, add a BLTouch, add a second motor, add new languages, activate linear advance, be able to mount a direct extrusion with a pancake motor, activate s-curve, junction, enable live-z, speed up homing speeds, filament loading and unloading, and many other things.!

Anet! Listen to your customers!!!!
