Basic Information:
Printer Model: DIY HBot with 4 NEMA23 motors
MCU / Printerboard: RADDS 1.5
Hello,
i want to upgrade my old DIY H-Bot (in principle CoreXY) with Klipper to use all adavantages (Input shaping, Pressure Advance…). I have done this also with another printer, but my HBot is a little bit more special regarding the mechanical concept.
It uses 4 instead 2 Motors (Motor 1 & 2)in the H-Belt configuration to increase the stiffness in Y and accuracy (more teeth in connection to the belts, shorter belt length from motor to carriage…
In principle motor 3 and 4 are in addtion (motors with pulleyes instead of counter-pulleys with bearing only) and should get the same signals as motor 1 and motor 2…
But I don´t understand how I can copy/clone the motor signals from Motor 1 to Motor 2 and Motor 3 to Motor 4 to the additional extruder pins where the additional motors are connected. In repetier this was very easy possible in the configuration tool. It also worked very very well for 9 years now, but now I want print faster with input shaper…
I would be very happy if you can help me to get the right configuration datas to solve this problem, I have added a sketch of my H-Bot kinematic.
