Has anybody tried this, or use this now? Is it worth the money? G-Wizard Calculator: Fast, Reliable, Easy Feeds and Speeds Gray
I have heard good things about it however I have not used it myself @GrayUK . Seems like it would be a great resource to have access to though.
I used it and it seems to work good (you can use it for 1 month free). But unfortunately, you have to pay yearly for it... which is a little bit annoying for us makers, who will use it only a couple of times a year... edit: NM, they have a lifetime subscription now
I contacted the CNCookbook team and they have discounts! Who would be interested? It would be for a 3 years subscription unlimited. After 3 years the software will limit you to a 3HP spindle (I don't understand that one though). I'll start a poll to know who would be really interested.
