GUIslice VS TeensyCNC

Here's one I used for a project: https://github.com/ImpulseAdventure/GUIslice

I am working on a project that uses an adafruit metro m0 express development board (using the ATSAMD21G18 ARM Cortex M0 processor) to drive a stepper motor. I have elected to use the Accelstepper library as it is well documented and makes controlling the stepper simple. The project also is driving a touchscreen display with the GUIslice library. Now - the Accelstepper library uses the main polling loop() function to repeatedly call the .run() method from the library to produce pulses to the stepper driver and move the motor. I have noted that when having the GUIslice function for polling the display in the same loop() function, it can hang the stepper motion for a split second as the processor is taking time to perform those functions (rightfully so).

which, for Arduino boards, can be found here.

guislice. I use it a lot for openhasp/home assistant touchscreens

This is definitely an approach that would work. There is an older project on GitHub where they remove the main processor and replace it with an Arduino compatible chip.

Whoops, *TeensyCNC. I definitely have a lot to learn, but there are some talented, knowledgeable folks at my Makerspace who would be happy to help / be moral support.

Answering my own post - https://github.com/seishuku/TeensyCNC

I believe that is only compatible with a (discontinued/non-supported) Cricut Mini. Not exactly an option for most users, even if they have the technical skill.
