I started with BB1.0 dual an decided to move toBB1.1 dual hybrid Titan MBL. I used the motors in the Package. These 2 extruder motors are 200 step stepper motors instead of the previous 400 step stepper motors. I installed Alex9779's firmware -hybrid-Titan-MBL (RC6). Question 1 : Do I have to change anything on the stepper drivers. Jumper ? Voltage ? I changed the screw for the x-as end-stop so that the nozzle of the right extruder is above the 0-line of the bed. When doing autohome the printhead moves to a point indicated on the display as X30 Y30 Z0. Looking where the nozzles are at that point in relation to the bed : - left nozzle is at X0-line and the right nozzle is at X68-line. When I want the right nozzle to be at the X0-line of the bed, I have to introduce on the display X= -38. Question 2 : Is that the correct way ? I want my the right direct driven nozzle to be the main one. The left Nozzle is the bowden one for support or second colour. Were will the correction of the -38 to be applied ?
