A new sandwich

Endpoint

As a sanity check, Iā€™m posting these pics for my new Endpoint sandwich. The last one just suddenly started having spi issues :frowning:

And true to form, the sandwich had to change due to wire routing constraints :frowning:

There is 1 Endpoint, 4 PowerStep01 drivers, 1 SPI Lcd module, 1 BME280 and 1 Mikroe CAN Adapter.

Also, as a result of the solution suddenly not working anymore, I decided to split the functionality between Endpoint and either Raspberry Pi 5 or Beagle-Y AI.

3d machine? What are you using for a stepper motor controller?

Using the PowerStep01 on the X-Nucleo-IHM03A1

Why not use something like this?

The PowerStep01 has both voltage and current modes. It does 1/128th steps and has an integrated stepper control computer that correctly calculates the pulses to move the stepper motors. Due to the deterministic nature of that control, all motors will move in sync with each other. They are also 10 dollars.

I ended up making yet another sandwich (sigh). However, I achieved the first significant milestone: Run G-Code for 1 hour without issue.

This is awesome. I was thinking about g code for something else. I am going to need your help soon.
