We have used maxpac with our CNC machine which has helped us achieve better productivity levels than what we were able to do manually before using this product. The user interface was easy enough even though it's not very intuitive but once you get familiarized you will be fine! Not much I disliked about MaxPac so far - maybe some minor glitches here n there sometimes when running multiple jobs at same time. Overall good experience working with them. Best way to improve your shop floor efficiency without compromising quality.
