So my R1 is an older one, not kickstarter, but early 2013 vintage i think, so doesnt have many of the changes that came afterwards. Printed ok to begin with, but never managed to get it to print what i considered well. Also had several issues: broken power switch, had to replace the arduino and the RAMPS board, melted wiring and connectors, dud bed thermistor, and all sorts of little things. But i know the printer can be excellent, and its hackability was why i chose it to begin with. So today the last of the parts I ordered to give it a refit and upgrade arrived, so its time to take it apart and rebuild it. Things i'll be doing: - Installing a Pi to run Octoprint - Replacing the hobbed bolt - Installing a proper cable chain to the carriage - Total rewiring to get rid of the cheap wire in it. - Replace the couplers (have new solid and flexible to try) - Replace the 5/16 threaded rod with 8mm rod. - Install trinamic 2130 stepper drivers (which will eliminate the end stop switches) - Replace the power switch - Re-do the LED lighting - Re-do the cabling to the heated bed to eliminate cable issues - Replace the RAMPS cooling fan with a Noctua - Tighten or replace the belts - And probably some things i've forgotten. Things i'm considering doing: (these will depend on the results from the above lot of upgrades) - Install an E3D titan extruder (or clone) - Add an Anycubic Ultrabase panel on top of the existing glass bed - Maybe remove the existing glass bed altogether and replace with an aluminium plate and better heater pad, and the Anycubic panel. - Maybe build an entire new corner levelling style base (not sure how on this) - Use lead screws instead of 8mm threaded rod - Replace the steppers with ones with integrated lead screws. - Replace the linear bearings with new ones, or polymer bushings. The printer has had an E3D hotend in it almost since new, a V5 at first, then a V6, with the nozzle changed now and then, so no need to replace that. Can anyone think of anything else i could/should do? I'm sure theres things ive forgotten.
