Paul Stoffregen is working on porting Marlin to the 32 bit Teensy 3.x.
He’s looking for testers with 3D printer hardware.
I just volunteered but I’ll need to get some new hardware first.

This would be serious nice. Not able to play around before the summer, maybe create a quick adapter board for ramps, until someone make a decent controller board with teensy socket?

I looked at Teensy 3, nice CPU but a bit short of IO pins?

aprinter already runs on teensy3

cool!

Marlin now compiles for the Teensy 3.1. Since my Mendel 90 has a Melzi with integrated ATMEGA chip, I’ll need to get something like a RAMPS board which uses an external Arduino. I can just cross wire it until I can design an adapter. My other option is to just breadboard the whole thing for testing purposes, which is sounding better to me

If you use a RAMPS, you will need to be careful of 3V/5V issues. RAMPS-FD or RADDS might be a better starting point.

I was looking to develop the evolution of the SAV Mk1 with an arm core and one of the thoughts was to base it on the teensy 3.1 and port Marlin to it. Since Paul is at it I might as well collaborate on his project. I will sign up for testing at least.

Good point @bob_cousins I’d need a bunch of level shifters… The breadboard idea for testing sounds better and better
