I have now done two tests, one EBB pen move command turning the motor one complete revolution in one second.
This was done for over 12500 moves without error. The second test was random length moves – in random direction – restricted to the range available on the eggbot. This test ran for over 21500 moves (Six hours) without errors. Video snippet of test.
The EBB board seems to “behave” OK but is very unforgiving on incorrect parameters. The EBB board will hang after a while if the duration for a move is 0 (zero). A negative number causes the EBB board to crash.
