kenimes 42 Posted March 10, 2008 " -------------------------------------------------------------------------------- I have both a refine 721 and pcut 630 cutter, I was having the same problem with the cutters not completing the cuts, freezing and locking up, loosing communication with the cutter etc..... I was using both cutters on usb and tried the usb to serial converters with no luck. When the cutters did complete the cuts they worked great so I was pretty sure that there was no problems with the cutters... Here is what I did to solve the problem, both of the computers I was using the cutters on were laptops with only usb connections, no serial or parallel ports......One had both a PCMCIA slot and expresscard slot the other one only had an expresscard slot, one is running XP and the other Vista.....I installed a PCMCIA to serial port card and an expresscard to serial port card to give me a db9 serial port on both computers and connected the cutters to the serial ports on both computers and to date both cutters have worked flawlessly..... Most laptops are going to have some type of expansion slot either PCMCIA or expresscard, just be sure to get the correct card for your machine so it fits and works correctly. I think what was causing my problems is that I was overloading the usb bus and just didnt have enough power to run everything at the same time (even using powered usb hubs). Cant guarantee that this will solve all problems but it sure took care of mine..... I got both cards from newegg.com..... Best of Luck.. Dale " Share this post Link to post Share on other sites
JV 1 Posted September 21, 2009 I read on another post that if you increase the baud rate on the USB ports it may solve this problem, like from 9600 to 19200. Not sure though.............. Share this post Link to post Share on other sites
Team Satan 1 Posted September 21, 2009 I also had the same problem with half cuts, freezing yadda yadda yadda. The USB to serial cable didnt work for me either. What I did find was, when sending the job to the cutter, the movement from the cutter was enough to lose communication with the software. Solution..... get the cutter ready to go, press the offline/pause button, send the data to the cutter (presuming you are using SB), once it completes its cut path on the screen and the little cut window disappears, press the offline/pause button again and off you go.

Brandon_Davis 1 Posted September 25, 2009 Interesting solution Xtreme... All communication problems come down to settings and correct use of the cutter. Over time everyone develops a system for working with them, experience is the true fix! Share this post Link to post Share on other sites
