I upgraded to CNC12 pro about 4 years ago to get the probing. The CNC11 probing add on was $800 whereas the CNC12 pro upgrade that includes probing was $299. Made no sense to pay $500 more to add probing to CNC11. Best to call them to see what current pricing is. CNC12 will run just fine on Win7 ...

Yeah, I would put limit switches on the machine. Not worth the risk of destroying a ballscrew.

You can still get that motherboard. Look on Ebay. Replacing with the same motherboard could possibly save a lot of grief trying to get Windows 7 running.

I have been happy with the Hitachi VFD's on multiple machines. Get one that takes single phase input.

There are other brands that will work fine. The Hitachi units have been in short supply in the last few years.

Looks like it is busting out into oscillation. Try tuning the axis.

Hard to believe that you spend the big money on the console and get the starter software. The Pro is what you want. The starter software is just a tease.

You are correct Black Forest. It is far more intuitive to teach from the users perspective when he/she is standing in front of the machine.

How about this 15 hp unit? 47 amp and $800

Here is a 20 Hp unit rated 60 amp:

I didn't spend the time to figure out the difference between ...

I've never tried it before, but couldn't you run a 7.5Hp motor with a 5Hp drive. VFD's have a maximum current limit so it would seem that you just wouldn't be able to develop full motor Hp. That way you could get a single phase 5Hp drive and not incur the expense of another motor.


It will work ...

The DC1 becomes drive #1 and pushes the other axis down. You need to set parameters 300 to 303 and 308 to 311.

So, (I think I have this correct) 300 should be 2, 301 should be 3, 302 should be 4 and 303 should be 1. Check 308 to 311 and make sure they read 1,2,3 and 4 respectively.
