I have a NEW990TDb 2 axis lathe controller, mine isn't setup as yet, the lathe isn't finished but we brought two into the country and Steve Blackmore up at St Helens has his fitted to an Orac lathe with VFD spindle and closed loop steppers and it's all working.

Not to bad to set up but now someone has done one the rest will be easy. Main thing is everything worked as it should, first thread was perfect.

Must admit though tool change will take some sorting out. On the lathe it has a plug on the back pulse +, pulse -, 8 sensor inputs and lock.
Probably be easier to hand over to an Arduino to do the sensing then hand back ?
Threading encoder, VFD and pendant just wired up fine to the supplied leads.
