So, what's different? The biggest difference is that they feature USB 2.0. Instead of a serial->USB chip built in to the cutter, they are now native USB. This is advantageous for a couple of reasons: Less drivers, Less complicated drivers.

In addition it features: More accurate stepper motors, Larger LCD Screen, standard included feed basket.

You can buy both of these cutters @ http://www.cutterpros.com

1) Turn your cutter off, and plug it into a free USB port on your computer. The new hardware wizard should appear, or if you've already done this, it should go "Bing Bong"

2) On the cutter, hit the online screen. You should see X000 Y000. Keep hitting "Mode" until you see the setting for "Baud." The value should read 09600. If it does not, use the arrow keys to make that so. Then, hit mode until you see X000 Y000 again. Then hit Online.

3) Make a note of the Com port and set the flow control. To do this: Go to Start, and then Run. In the box enter:

devmgmt.msc

Then, hit OK.

4) Hit the plus sign next to "Ports COM And LPT"

5) You should see "USB Serial Adapter", Right click on this and go to "Properties"

6) From there, select "Port Settings". Set the flow control to "Hardware"

7) Hit "Advanced", Make a note of the Com Port, and if possible change it to something 1-4 if they're not in use.

8. Hit apply and OK to leave those menus. Close device manager.

9) Open Flexi, use the "T" on the left hand side to type a couple of letters.

10) Go to File, then hit "Cut/Plot"

11) This opens the Cut Plot screen. In the top left you should see CR630 @ com x or CR-1200 @ com x. The x needs to match up with the com port we noted earlier. If it does not:

12)Hit the properties button under the CR1200 @ Com x drop down box. Select the right hand most tab. It has a picture of something that looks like a microphone.

13) At the top, change the com port to match yours. Hit OK

14) At the bottom, make sure "Flow Control" says "none"

15) Hit "Send" on the cut plot screen. Your cutter should come to life.

1) Make sure your pinch rollers are the same tension.

2) Make sure you have the proper blade offset.

3) Your pinch rollers may be just plain worn out. If the above two didn't work, try replacing the rollers. One year of use is their average effective lifetime.
