Ender3 pro Adjustment wheel for 42-40 motor upgrade on the y axis.

thingiverse

I have upgraded my Ender 3 pro to run with a double hot end and 4 extruders. With a duet 3 mini+5. The x and y axis have been running hot since the conversion. I installed heat sinks on both of the original 42-34 step motors. The x was still running around 48c and the y around 44. I was able to change the x axis without any issue to a 42-40, it runs at 34c without heat sink. The y axis required the use of a smaller wheel to allow for the complete motion of the carriage with the installation of the 42-40 stepper motor. The y axis motor is running at 37c and the prints have a better surface finish. I have include the file for the 47 mm wheel plus the y limit switch support bracket to adjust the position of the bed for custom hot end assembly. The step motor vibration pad should be printed with flexible material at a low infill density. To reduce the vibration on my ender 3 pro I have installed a support under the 40x40 profil of the y axis close to the belt adjustment system. This support help to lower the vibration due to the cantilever geometry of this printer. The lower pad should be printed with tpu. and adjusted along the z axis with the resize scale option to achieve the final height. Insert: M4*8-5.2
