Dragonframe - eMotimo shields
Hey Folks.
Just a heads up, I have an eMotimo TB3 that I am retrofitting into a dragonframe controller.
The PCB's are on order, it is designed to replace the innards of the eMotimo and will give the ability to run 6 motors. It can also easily work as a stand-alone motor controller without the emotimo as long as you have an Arduino Mega.
I know i know, the eMotimo is already dragonframe compatible right?
Yes. but problematic. I constantly ran into connection drops with the stock eMotimo firmware. It seems to have a hard time staying connected for more than a day. A friend of mine gave me a copy of the DFmoco/DFremote sketch that worked with the existing pin-outs on the eMotimo and now it runs flawlessly. There was something about the rest of the eMotimo firmware that causes stability issues. I figured I may as well just replace the PCB in the eMotimo with one of my own design that allows for control of 6 motors.
The minimum order for these prototypes is 10. I plan to keep 2 of them for myself, the other 8 will be up for grabs. 3 are spoken for. If there is enough demand Ill order another batch.
Cost would really depend on how much work I need to put in. Ill part with a bare PCB for $10, but I am also willing to go all the way and do a full retrofit on an emotimo for a price. Keep in mind, this setup would make it 100% reliant on dragonframe, and it will probably require AC power. But if anybody wants to get some more axis control without breaking the bank, this may be a great way to do it.
