Hi Guys,
It's been a while since I visited CNC-Zone, Its definatlye grown.
Ok I have been playing with Mach3 formular trying to get a http://hektor.ch/ style Two motor hanging painter to work. I thought I had the formular right but it doesn't seem to work, Has anyone been able to get somthing similar to work in Mach3 ?

Where:
x = xaxis
y = yaxis
A as motor 1 (top left)
B as motor 2 (top right)
500 = distance between motors horizotaly
f(a) = sqrt ((x*x) + (y*y))
f(b) = sqrt (((500 - x) * (500 - x))+(y*y))

Should this work?
Cheers,
Jono

I don't think it's capable of doing that, but not sure. Ask Art on the yahoo group.

Art discussed this before. It's possible to use a PKM machine and Gcode with Mach 3. But the jogging buttons will not feed through the formulas. So the machine will jog each motor independently :( He said he would work on this but now that he's retiring in a month, it doesn't seem likely it'll see the light of day.
