The GRBL Project

I offer 2 5 Axis boards, the Teensy based T41U5XBB and the RR2350 based RP23U5XBB. People frequently ask for help in selecting between the two. As is typical when asking a question like that, the answer is "it depends". Before I dig into the differences, either board is a very good choice for the vast majority of CNC systems. The Teensy shines in processing power due to its 600 MHz clock rate and large amount of memory. It can sustain an output step rate of 400 KHz.. You can
