I have brought my Y axis motor back into the house, so I can play about with mach 3. Its cold in the workshop and a little damp at the moment. I am on with my Y axis motor mount, so time permitting I will have it running in the next two week.
The oscillation is because the drive is struggling to settle and find position the drive then faults because couldn't find position fast eneough. you'll need to play with Gain(PID) settings in the drive. But first I'd check your table is moving freely and the Jibs etc are not too tight.

Also you cannot set the PID settings or rather tune the motors on the bench. To do this correctly must be on the machine and working exactly as would in use. By that I mean with all guards, vise's etc permanently on machine while in use so can tune to weight your shifting.
