Definitely exercised the tool changer today. I did one project with 4 different tools, others with 3 tools. In the past I'd try to minimize the number of tools needed for a project because of the risk introduced when changing bits and getting the Zs to match. That is no longer an issue -- everything lines up perfectly.
I've been playing around with speed and was doing some cutting at 300ipm in the XY, and Z.
One part of the learning curve for me is using tabs. My old setup had a vacuum table which worked really well. But since my "shop" is my garage in a very residential neighborhood I opted to go with mechanical hold downs. On the last project of the day I underestimated how many and where to place the tabs. Lesson learned.
The Z is consistent enough that I may just use onion skin. More experiments in the future.
