/diy/ - Do It Yourself

Yes, bigger is actually better. If you'd actually print a bunch and design your own parts, you'll quickly learn that one of the big restrictions is your build volume, and 220mm ain't enough. 400 is better, but the week I bought my Chiron I got a request for a 450mm part, so I had to severely modify the model to get it to fit and get paid. In the 500USD price bracket, there's basically two options: several of the good ~200USD 220mm printers, or a bigger printer like a Chiron or CR-10 if you need it, because two 220mm printers aren't a substitute fora 400mm unit. FYI, it still ain't big enough. Never is. The day I told people I was going to build a 2000x1500x1200mm printer, I got requests for a 2000x1500x1500mm part.

Didn't say it was a CNC mill, just a CNC. Which it is. Was. May have been. I don't need to go fast with a huge nozzle anyways.

Not sure if this belongs here, /Ohm/ or /EMT, but here goes:
I'm working on a big CNC machine that's heavily dated, and we want to convert it for 3D-printing big stuff. The machine ran, sorta, a decade ago, using servo motors and Electrocraft BRU-200 drives. This gives me two options:
>Yank out the expensive servos and drives, throw in fat steppers, hook up to a 3D-printing motherboard, bob's your uncle
>Somehow find a way to get a 3D-printing board (RAMPS, Duet, whatever) to talk to the servo drives
What would you consider to be the most feasible option? We've gotten the bastard to move agian, but only barely and without the encoders. Is there any easy way to hook up ancient servo drives to modern 3DP boards?

You mustn't be afraid to dream a little bigger, darling.
