    Hi Paul I love your work! :) The plot is just some test software I use to debug. It plots out values sent over serial similar to the Arduino IDE's "Serial Plotter" but without the annoying rescaling. I have some more...

    To see if I could go without the complicated hardware timers, I ran a test ramping up a stepper to 100us period step speeds and this worked absolutely fine without using hardware interrupts. One strange I thing I...

    The timers I am mostly interested in are the ones used to generate the step pulses for the stepper motors. I just did some simple tests and with the insane speeds of the Teensy4.0 I'm thinking maybe hardware timers...

    I was kind of hoping there would a more general introduction to hardware timers somewhere... But all good, I will try going through the timer code for Teensy3.5 in Marlin (and the other code you both have suggested)...
