Yes, I am getting to grips with the controller. It is definitely not intuitive compared to Haas. There is a lot more menu poking on the soft keys to get where I want to go. I can upload and download programs from USB, but for some reason can't do the same with a CF card, even though I pick the right device and do the same steps as for USB. The DEM and Fusion 360 play nicely together. It took a ton of soft key poking, but I was able to edit the keep relay for the chip auger so it is manual only, rather than automatic whenever operating at a feed rate. I prefer this for my style of working.
I do my tool length setting offline with a 40-taper socket and a surface gauge on a surface plate. That works really well when combined with a Haimer probe in the DEM. I had used this approach with my old Deckel, but it works better on the DEM because the Deckel did not have a global tool length offset table.
So yes, I am happy with the machine.
