Cr10s-pro to Prusa MK3s extruder adaptor aka CRUSA

Last crawled date: 4 years, 3 months ago

This is my adapter plate to use an Prusa Mk3s on my Cr10s Pro. I chose to adapt this extruder because I know there is a lot of great options around to upgrade it to almost anything you want including future evolution of its design directly from Prusa.
Things to know:
find all the info and printed parts stls for the extruder itslef from the Prusa website
-The two blue arrows on one of the pictures are to add two M3 washer there
-You also need to set a couple M3 nuts on the back of the plate where the extruder attaches.
-Use a bowden tube for the cable management there is a spot to zip tie one on the top piece (use two M3 screws to attache this piece)
-except for those washers you can reuse the original hardware from the Pro
I chose to center the extruder between the carriage wheels for balance
-because of the new nozzle position you need the new x and Y endstops holders for it to be right.
-You need to change your firmware accordingly: E3d V6 ( I used a trianglelab clone), direct drive, pinda position.
I originally tweaked the Tiny machine firmware for it and it worked great.
the Vref for the extruder stepper was very high on my Cr10s pro, make sure you turn yours down, mine was set at 1.4v and I tweaked it down to 1v. My extruder get just warm now and does not skip a step ;)
-The cable chain attachment part is to be used with a rework of the break out board position and filament sensor that I will post later.
I have been running it for many month and I'm very happy with it.
I hope you like this mod and let me know if you have a question.
