I didn’t see this post before…..shame you sold your Sprint.
Gerber software is best for thier cutters, I find Corel is longwinded against dedicated sign software, but it does cut direct to Roland I believe without bridging software.
While you may have had an old PC, and you didn’t say which version of GA software you had, you could easily obtain a more modern PC knock in the software and away you go. The nice thing with Gerber is that they support there products all the way back.
As Shaun said you could have exchanged your LMK module for a Cadlink one to run other software.
Again for what your doing you had a good set up perhaps a little unsure of what to do with it.
I have Gerber’s latest software Omega, but run an old Sprint for contour cutting my Gerber Edge prints, I also run a new Summa Sign Pro for my regular vinyl work.
I know this is all water under the bridge know but maybe useful for anybody in the future. GA was a great program for plotting with!
