I'm retired, and don't make many signs. My old computer that I've used for years has finally died. I'm switching to a laptop, and I've installed Sure Cuts Alot 3. My question; How difficult is it to get the MH871 to cut with Sure Cuts alot3? What tricks are there?
If it works with that cutter, it works. What are you asking?
Personally, you would be better off by ordering the $50 VinylMaster program, it's more versatile and robust, with a great Vectorization tool (converts images to cuttable files).
Or, even SignBlazer Elements (Hybrid version 7.0.0 -- using RedSail model for your cutter).
Here is the Serial emulation USB driver ---
