Koike Hybrid D10

Guys,

Having issues with my plasma cutting erratically and speeds not what they should be. Seems all over the place.

I have had a look at all the parameters and also had the internal boards looked at, and some parts changed, although the company said they didn't think they were at fault.

I have tried the controller on another bed and is the same faults, so must be a controller fault.

Anyone here throw me any other ideas to work on, or somewhere who sells refurbished ones?
