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 this to add the X and Z cable chain: https://www.thingiverse.com/thing:4155541

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.
