Does anyone have any parts for a Burny 2.8 controller?

I am using this controller on a plasma cutter and when the machine cuts in either just the y direction or just the x direction it cuts fine. When it needs to travel both in the x & y direction, like a miter is when the machine stutters and creates a jagged cut.

Also I used to be able to download from my pc to the controller at 2400 baud, but I had to set it to 1200 baud for the entire part to load.


Any ideas?
