pat dont know the difference between a ROLAND PRO plotter and the entry level CX/GX/CM-24. these are not the same built machines as any of the older PNC-xxxxx models or the CX-300, 400 &500 machines. i have NEVER OWNED A CX/GX-24 for that reason.
i started in 1992 with a barley used PNC-1000. was offered a GOOBER 4B, but saw real quick the road that was gona take me down!!! $100 A FONT? you gota be crazy. no thanks.
i got a PNC-1000, was already way ahead of the GOOBER 4B as it not only would cut 15" material but it could do 18" or 20"!!!!!! not only that but i figured out quickly i could cut from any graphics program that sent info to the plotter in HPGL. COREL fit that need. not only could i cut from corel but i had a cd with 1500 FONTS on it and COREL & THE ROLAND..........could use any of em!!!!!!!! so i never reconsidered any other plotters.
i run the dog poop outa that 1000, which i paid $1600 for used and sold it for $600 AFTER i bought my next used ROLAND. this was a PNC-1100, now i was in style with a full 24" cutter and double the speed of the 1000. i give $1000 for it. i set up a mobile sign truck, and bought another PNC-1100 to put in it. give same for it as i did the other one. ran both of these with never a problem sole em both for $1000 when i got my CX-300...........sweeeeeeet machine. cant even hear it working, 30" down to 2" material.
all ROLAND PRO OR CAMM-1 MACHINES are built with ball bearings on any rotation point. just like your cars front wheels roll on steel bearings and look at the miles you get on that. the CX-24 or comparable low end plotters use nylon bushings on all rotation points. THESE WEAR OUT............quickly.
