I am using Roland CAMM-1 model PNC-960 24" Vinyl Cutter & Plotter
With Corel Draw works fine.
If i want to cut something with Inkscape, nothing happens.
Any suggestions are welcome!!!
Please help me!
If i can not use it with cutter, it is unusable for me.

If you haven't already, try searching this forum. There has been a few posts about cutters, but I'm not sure if any address your issue.

As far as I know you can not print directly from Inkscape on Windows. Very few programs will actually cut with Roland's driver. There are people who do this on Linux systems though, piping the output to other programs. When I first started I used SignGo Lite. Imported my Inkscape work as WMF for cutting. SignGo just cost too much money, for the quality/functionality. I ended up writing a program that parses SVG path data and spits out HPGL to the cutter. It works for me. Kind of a PITA. I've kind have stalled on the program, mostly because it does do what I want, and it's really hard to find time.

If your like me, it's really hard to find one program that does everything you want, does it well, and is cheap/free. I recently got a demo of CorelDraw--looking for a better way to cut, and I found that I actually preferred Inkscape. I had to cleanup a crappy eps file to make it cutter friendly. I tried cleaning in just Corel, started over bouncing between Corel and Inkscape, and then just Inkscape. The weld tool in Corel drove me nuts, Inkscape just did what I expected. PowerTrace didn't really impress me, either. Inkscape has spoiled me, I was just expecting a lot more for the $$ from Corel.

The one great big plus I had for Corel though is the text on path tools. In Corel I draw a random line, attach some text to it, grab a handle for the text, and I can resize the text relative to the line. That is if the text covers a 1/4 of the line I can scale it to the full line length, and the text follows the line perfectly. Inkscape doesn't work that way.

So, just because you can't cut directly from Inkscape--doesn't necessarily mean it's of no use to you. It's just another tool. Give it some time you might find something you like.

I have no problems with Inkscape, i just can not use it if it does not work with Cutter. I do not know how to send this file to cutter.

Then you didn't read the previous post. Export from Inkscape and import into the software the cutter.

There is another way, our program is Signcut which works directly with Inkscape. It takes the Inkscape vectors and opens them directly ready for cutting.
