TMC

Open guestisp opened this issue 2 years ago • 1 comments

Any changes to have support for TMC (in fallback mode, not UART) ?

They are working fine acutally , but i'm thinking they are a little bit slow compered to a Marlin/Klipper printer. Even setting 120RPM, they doesn't got at 120 for sure. We are near 50rpm....

This library does software bit banging (flipping the step output), it is going to be slower than timer-based or SPI/UART. Multiple motors, but in particular high microstep values may hit an RPM wall, sooner even on 8-bit platforms.
