Hemera - Creator Pro Carriage

thingiverse

Update 22/02/2020: This mod is working great, many dozens of prints so far. I have used a cable chain to take cables from the head to the back side of the printer. I have only bodged up a makeshift stand to hold the chain to the head assembly, but it's working fine so far; I may design something better in the future. This is a replacement carriage for the Flashforge Creator Pro. This is still a work in progress! But it's currently being used in my machine! This is a Single Extruder Modification; it may or may not work with the factory firmware. It's working in My machine, which has a Duet2 board fitted. 18-10-2020: You may need to reduce the carriage scale by 1% if your carriage binds on the left side of the rails (when sliding it back and forth once clipped onto the bearings). Check for binding before you attach the belt as zipping the carriage back and forth with the belt attached will generate current via the stepper motor and may back feed into the control board! (Not a good thing.) You will need to remove the factory carriage first. The Hemera Carriage will clip onto the existing rails and bearings. Connect the belts to the carriage via the belt locks (2); the belt will have a twist to vertical. This is required so there's enough room for the extruder assembly to fit between the rails. There are 4 captured M3 nuts to be fitted underneath. One bolt on the rear mount (L bracket) is used to hold the bracket down to the carriage via the outer screw holding the right-hand belt lock. The front L bracket, once everything else is in place (including the Extruder Assembly), gets CA glued into place; this becomes a permanent part of the carriage. The rear L bracket can't be glued as it needs removal for any belt maintenance. Make sure your M3 bolts are not too long for the mounting of the extruder assembly. Maybe do a pre-install assembly to check for bolt lengths first. I may or may not post a hardware list: 3 x M3 12mm, 1 x M3 16mm, 4 x M3 nut, Bolts for extruder attachment are included with the Hemera. On assembly, the extruder would be fitted from the bottom up. Allowing the cables to pass on the left of the carriage between the rails. *** Please hang fire on printing this until I design the endstop flag as it will collide with the X stepper motor. Alternatively, print a calibration cube and glue it to the carriage so the endstop is triggered earlier. Credit goes to https://www.thingiverse.com/thing:1350343 as I used his model to inspire the factory bearing support and some clearances. I did use his model with an E3D for some time before purchasing the Hemera. Thanks, mate; it's a well-designed piece of kit!
