@o_lampe There are 2 motors on each z axis and 1 motor on each Y axis I actually got this to work as fine as homing and moving correctly. I found a way to home both Z axis by adding the commands to the homez.g. What it does is first map the first Z axis with the first 2 motors then it remaps the 2nd Z axis with the other 2 motors and after it's done it combines all the motors into one Z axis motor.
It would be my goal to have both tools to extrude simultaneously on the same part so that basically it would cut the print time in 1/2. The chassis that I need to build for autonomous vehicle is divided into 3 parts and 2 of these parts took about 4 days to print -this was on a printer I bought but was very disappointed with it. I then decided to build my own.
