Curious -thanks, yes of course that is why I am getting rid of it. It's a great printer, but upkeep / materials are $$$$.I do have a dongle reprogrammer, and I have been using other ABS filament. But I find that respooling it onto the STratasys spools is a pain in the arse. Since the spools fit inside the machine you can't use anything else, so you must respool.The reprogrammer lets you reprogram the Stratasys dongle to tell it that it's full.But otherwise parts are expensive. That pinch roller I just replaced was $125. It's a nice machined part, but holy cow.I was hoping to find someone that has a printer farm and could use it as a spare or something.Thanks for your advice.Dan
