I have had a Shopbot since 2000 doing light commercial projects mostly prototype work. We had a plug problem with a x motor and it took out our control system. After working with Shopbot I looked into different control systems. We also do laser work and get much more control with that controller. That is how I found Gary and the Acorn system. I can not say enough about the easy installation and the control options the Acorn had. My wife works in the shop and was always afraid to run the Shopbot because you always had to pull in programs to do much, unlike the Acorn that provides buttons to most of the setup. Gary has been super for support and setup. Coming from the Shopbot control we did run into a few things that needed to be dial in the machine and Gray jumped right in and we got all up and working. If I were a hobbyist or light commercial like us I would not go to any other control then the Acorn because of the easy operations and options that you can use and the quality support from Gary. I understand that there is talk about a less expensive control but as a hobbyist you want to turn out high quality work in a reasonable time then I would stay with the Acorn. If I had to do it over today I would buy the Acorn control from Gary in a heartbeat. The support from Gary is worth the gold. -Chuck B.
I was primarily motivated to make this upgrade because I was not able to resolve software glitches and communication errors with the ShopBot control system. I was more or less satisfied with the performance of the ShopBot system when it was working. But - wow what a difference in controllers! With smoothing turned on in CNC12, and set at defaults for a "precision router", this system is sweet and smooth. Did I say smooth? It is SMOOTH! It engraves text more smoothly than I have ever seen this machine run before. The Clearpath servos are probably part of the improvement too but I think the biggest difference may well be the Centroid control software. I have a lot to learn. G-code is new to me. But this upgrade feels solid. Thanks to Gary for his help with this project! - Gerad M.
