Thanks for the replies. The machine is 3phase and I've only got a single phase supply in my workshop but I'm happy with setting up VFDs. The table motor as mentioned needs rewiring from star to delta. I found some photographs on this forum from someone who did this already.
Do people think the price of the machine is fair? I appreciate that you will pay a premium from a dealer, but they are able to get it delivered easily which as I live in Scotland is very handy.
My power feed runs on a 230V VFD, but remains wired in star config. I've never experienced any problem, as yet, with the reduced power. The spindle motor on mine, as a matter of fact, is running with a 220V VFD but is wired Star. But I have taken into account the reduced power output in this configuration for its duty.
I consider the 2B to be a fair improvement over the 2A (the knee operation, table size and headspace. Mine also has a long riser block, so even more height available over the table when vertical milling – and I don’t need to remove the vertical head to go milling horizontally.🙂
The power feed versions lose about an inch of long travel, if that is important and I really appreciate the DRO on mine. Avoids any backlash adjustments when positioning the work.
I find that supplier usually inflates the listed sales price somewhat above reality.
