Hi,
My first post. I'm a CNC machinist from Finland. At work I use VMC and as an hobby I have converted Opti BF 20 Vario to CNC with my friend Andy55.
Andy55 has built our Geckodrive stepper electronics and take' s care of the
computer things also. We use EMC2 control. I take care of the mechanics.
Few pics of the current state of the project below. There's actually only
column and base left from the original machine anymore...
You can watch a short video of the machine on action from here:

Put enough volume, sounds are good!!!
I will post more videos later. Rapids are painfully slow, put with small steppers
it's better to have low acceleration/ top speed and have good reliability.
I have stalled steppers too many times with higher rapids.
DC servo's are coming...
