Hi, Asle from Norway here.
I am a mechanical engineer, but I am completely cr@p at programming anything more advanced than a vcr
I am building a large cnc router with travel in the areas of : X1300mm, Y2800mm, Z300mm. The structure consists of aluminium extrusions 90x90mm and 45x180mm. X-axis will be run by one belt, Y will be run by two belts, and Z will have a lead screw (or ball screw, I haven’t decided yet).
My initial plan was to use NEMA 34 steppers, as information on sizing of steppers is well explained on at least one million cnc websites, but I want closed loop, and I really like the idea of using bldc motors in stead of steppers.
And so over to the questions: Has anyone here built a cnc router, and are you guys able to help me choose the right size and power bldc motor?
Question two: It seems to me that the oDrive controller can accept Stp.Dir.Enable - signals from a break out board, Arduino, RaspberryPi or similar, and I guess the oDrive has to be set up for this. Does the oDrive retain the memory, or do I have to perform this set up every time I power up?
Sorry for the n00b questions, my programming skills are limited to simple editing of Arduino code, and old fashion PLCs…
