This is a project I started several years ago. The project has stalled multiple times due to other projects taking priority. Now, I have decided to finally get this machine up and running, and in that context, I have chosen to use a Centroid Acorn controller.
I like to build things myself and learn in the process instead of buying ready-made machines. I have several other ongoing projects, such as a laser cutter/engraver, 3D printer...
The machine frame is made of Bosch Rexroth profiles and rails.

While I wait for the Acorn controller, I am using the time to work on the rest of the components in the control cabinet - I have mounted the rest of the components, but haven't started the wiring yet.
- Toroidal transformer-based power for stepper drivers
- A small 24V power supply for controlling the contactor
- Noise filter for 220V input to Acorn 24V/5V power supply
- VFD (Variable Frequency Drive)
- Leadshine DM856 stepper drivers

Nice design, I like the placement of the Y linear rails and ball screws.

Some progress – stepper driver power is OK.
Currently working on the emergency-stop setup.
From the tracking information, it seems like my controller will arrive tomorrow.

Some more progress - I love work like this!
Next Steps:
- Perform the initial controller test.
- Wire the stepper drivers...
Setup Details:
Running the software on an HP Core i5 vPRO 10th gen (32GB memory) with a 21" ASUS touch screen.
