I have been doing some looking around at the Fadal VMC Controller upgrades. I know and have read about the Calmotion upgrade and the Fadal NXGEN upgrade. In looking around I found another one that is very interesting. What I have found out is that the one company had a branch in Houston, TX but is no longer there. Here is the article on the Upgrade. There was a post about it on the Zone in 2017 but no others. The hardware comes out of Germany but looks to be a pretty cool package. Not sure what the cost is but very interesting to read about the hardware and how the software works. Here is the link to the article. I have also attached a link to the hardware/software brochure on the controller upgrade. Without knowing the cost of this product and support, so far Calmotion seems to be the best choice. Just thought I would share to see what others on here might know.
