I picked up a slightly used FC3100-60 this weekend for $300. The owner claimed it had been in storage for 10+ years after he replaced it with a larger cutter. It test cuts perfect but I cannot get it to communicate with my computer. I have tried HP-GL and GP-GL settings. I am using the parallel interface on LPT1. The interface setting is at RS-1 (9600 8bit N H)I also tried (9600 8bit E H). I checked that the COMM settings match. I can switch the cable over to my Copam and change the settings in SB and the Copam works great. SB has a setting for the FC3100-60 and from the literature I found from GraphTec it does not need a special driver and it should work with generic HP drivers. Any help would be greatly appreciated.
