* Except , I hear, the newest version of the Carbide Motion board, where you need to keep a button pressed to be able to program the board via USB. The button is near (or under) the big capacitor at the top-right of the board. This could well have been your problem, not a missing bootloader, becaus...

Xloader* not closer

Idk if you've figured it out yet but I had exact same problem. Could not ever upload with arduino ide or closer but could connect with carbide motion or bcnc. I managed to screw up grbl tho

Then I tried connecting an arduino uno and had no problem flashing with ArduinoAsIsp in the ide.

Same thing. Look for dnp611. Cheaper cuz it just motor

that was the correct choice. its an arduino uno with stepper drivers integrated

Inventibles I think sell v wheels. The one order I've made from them showed up in California in just a couple days

Look for "shuttlecp" on github

Are the so3 steppers powerful enough to effectively move the extra weight around or would more powerful ones be recommended?

Probably 2 pins for + and 2 for -. Carry more current. Might be wrong

Were you able to get .9i loaded successfully? Is it correct to assume that some of the pins will switch now? Or did the pin changes happen prior too the installed version?
