I have an old S03 with the original CarbideMotion v2.2 board that is running grbl 0.99. I’d finally looking to install limit switches and upgrade the board but it appears all references to the CarbideUpdater that Carbide used to have are removed from the site. I emailed support and they just told me to purchase a new board. Which seems wild to me.
Does anyone have any archive of the documentation and files needed to perform this upgrade? Any advice on doing it? I believe these boards are running arduino, can I just use any grbl 1.1 upgrade guide for Arduino ATMega328?
My SO3 was built around 2016. I had to upgrade the gbrl but eventually just bought a new board. I also added the Bitrunner and the original board I soldered the connector on. However the USB connector was sloppy and I would lose connection.
If you buy the new board get the enclosure. The original boards had a big heat sink the board sat on and for the new boards you remove that. Plus the board enclosure is in two pieces and have a hole in it for the BitRunner connector. The BitRunner was a fantastic upgrade. I also upgraded to proximity switches and have an HDZ. The old SO3 XXL runs so good it is hard for me to justify upgrading to a newer machine. I have made thousands of projects on my SO3 and I can always count on it to perform well. If you decide to upgrade to a newer machine consider selling your SO3. There is a market for CNC machines but it is a small one. It usually takes me a month or more to sell woodworking machinery on craigslist. I am not on FaceBook but am told the market place is also a good place to see specialized equipment like a CNC.
Just remember to do the oil maintenance on the HDZ on a regular basis. After the maintenance place a paper towel under the linear rails for a week or so because oil drips down. Also before starting a project wipe off the bottom of the rails to keep oil from dripping on your project the first week or so after maintenance.
