Yes! I've managed to scavenge an old pen-plotter that was obviously gathering dust down in the basement of our institute. Last time i've seen such a plotter was in the 1980s at the institute where my father used to work. Back then, it was a paper-feed pen plotter that was used to plot various measured data online.

The DXY-990 plotter shown below can hold eight pen at the higher left part and moves on an xy-plane using two stepper motors which control a ribbon each. Each initialization process involves finding the lower-left corner which seems to be offset from the x-position of the pen. The plotter can be loaded with a paper size slightly bigger than DIN A3. The paper is held by a controllable static charge (wow! when did this technology disappear?) so that it doesn't move when the pen is hovering or scratching on it.

I've just had to install Pro/Mechanica and i had Pro/Engineer already installed. Since the Mechanica module in Pro/Engineer refused to work unless in "FEM-mode" i had to go into the psf-file and change the following the line:

[code] ENV=MECH_LP=X:\Programme\mechWildfire 3.0 [/code]

The .psf-file can be found in the bin-folder of the proE Wildfire 3 folder. Mine was called proe1.psf.

Now Pro/Mechanica does the job, but now i'm having problems with my model..
