Attempting Again #1

Uploaded the program.

Bricked the AT Tiny

The entire circuit was working but I accidentally bricked the AT-Tiny trying to debug a minor program issue. Caused by changing the clock setting.

Lesson Learned: Moving fast and breaking things is great for software. Not much fun in hardware.

What was the prorgramming issue? The problem was caused by not changing the pins, since I had changed the design. I found this out by debugging using the ATTiny on the breadboard and exploring the design.

Problems with The Machine

Broke most of my bits since the machine’s auto calibration was problematic. For some reason it just wouldn’t configure correctly and I tried milling atleast 8 boards without giving up and trying something else.

Resolution

I resolved the milling steps by manually calibrating the machine and adjusting it accordingly.

I’d set the Z-Offset very high and then manually adjust the z-axis until it was calibrating correctly.
