The Arduino was controlled by my laptop, which blocks me from doing other stuff while a job is running.

It did a pretty decent job as long as I didnt push it to its boundaries.

It had a hard time to keep steady while doing some tougher materials than MDF When I started with my first machine, all was completely new to me and I did not want to spend much money on my first motors so NEMA17 sounded like a good choice back then.

The moters a somewhat bigger in size as well so I have to adapt my machine a little bit.

I wanted to make a standalone box, so I decided to control everything with a Raspberry PI.

My machine has 2 Y-rails so there are 2 motors connected to the Y-axis.

Grbl Controller For Raspberry Pi Drivers And Not

I decided to connect the data lines coming from the RPi to two drivers and not to configure the A port on the HAT as an Y-output.

Also I made to switchable 220v outputs to control the power to the spindle and the vacuumcleaner (which has a tornado system, separating dust from the airflow, also diy).

It runs bCNC, has WIFI to get my gcode from my dropbox and it frees up my laptop.
