Just knocked a quick script up to read in an excellon drill file and display it using pygoocanvas:
The lines show the path in the file. Tool changes aren’t yet shown.
Source coming later. After sleep.
- Add 4 lines to the firmware for the MSP430s that sequence the stepper motor drivers so that they half-step (so that there are sometimes two active coils).
- One’s resolution has doubled.
- Push changes up to public firmware git repository.
We did have a resolution of 0.2mm per step. Now we have 0.1mm. w00t.
