ok... so I am just trying to get my guy back up and running... I think I am just going to print the front motor/extruder mount?? that should fit the older style.. I wanted to rotate the motor... and or removed it in order to replace it with a bowden style... I think that would increase the accuracy immensely... since that heavy motor tends to bounce around on the end of that long run... ? what do you think? The way I want to work it is so that the end only holds the extruder... auto level.. and entruder fan..
