I really like the MK3s extruder... I made a version that fits the mini

Its a work in progress. I'll update this if anyone is interested.

Finally ran my first PETG print and it worked with no stringing with good bridging

Do you mean extruder or hot end?

I am pretty close to finishing the pieces. It is now printing multi hour jobs with the modified MK3s hotend

i am done with the functional changes. it now prints with no errors, just as self-test and mesh bed leveling. i just need to tweak a couple more things!

i have printed PLA, PETG and ASA ... with no issues or stringing

Looks good, I hope to one day make the Mini a direct drive extruder with dual z axis (like a true Mini MK), this is a step in that direction, cheers. Do you know how much mass your changes introduce compared to the stock hotend?

Also, I see your MINDA probe is actually a PINDA from a MKxx, does that seem to work ok? Have you had any issues with mesh bed leveling or inconsistent first layers? Did you need to modify anything for it to fit or work properly?

@malcmcm

hi there, we did modify the x carriage body to hit on the same place as mini on the bed, we are waiting for the heated bed and the second z axis to build it.

we will let you to follow the post where files are for the upcoming updates pictures and issues we might encounter.

cheers
