We bought Rapid-PCB and then modified it to create Carbide Copper. You can use either, I don’t see us taking down Rapid-PCB so it’ll be there if you want it.
Regarding future development, We’re a small team and we bounce from product to product. Early this year we did Carbide Motion 4, then Carbide Copper, then a big push on Carbide Create, now we’re back on a big update to Carbide Motion. Once we’re done with the current CM update, we’ll circle back to Carbide Copper for more updates.
