After installing an update, PTPublisher Mac does not correctly identify the drives in my robot. The robot drops a disc but the drive never opens -or- the arm grinds into the top drive -or- projects do not start after clicking GO. (PTPublisher Mac).
The drive assignments have been lost after the update. Follow these steps to reassign the drives:
1. Once PTP is open, click on the PTPublisher menu. Choose Preferences.
2. Click on Reset Drive Positions.
3. Close PTPublisher.
4. Open it again. You will be prompted to choose which drives are open.
