Cutting a Rectangle with knife point on chipboard

[Gail]

I have made several attempts to cut a rectangle 10.50 x 9.50 inches using the long blade with the click holder on chipboard. I use knife point to set my orgins and MTC to draw the rectangle. My offset is .40. It cuts the long side perfect, but shortens the 9.5 to 9.25. I was using .30 off set and changed to .40 and it is no better. Of course, I have obviously forgotten every thing about why I should calibrate and when to use it....can anyone get me started again please?

[Elizabeth]

Have you tried doing a factory reset in case your settings inadvertently got changed? (You should only need to calibrate for print and cuts.)

If it is the 60 plus blade try an offset of 0.7mm.
However it may also be that you have some skewing, an extra pinch wheel would help with that.

This sounds like the same problem I was having with the rhinestones size holes and the long blade. Lesa

[Gail]

Yes, it is the 60 long blade. I actually taped the chipboard down with painter's tape to the mat. Don't believe I got an extra wheel with my BC. Is this something to be ordered?

There should be 3 pinch wheels on your machine. If you use all three that will help keep media from skewing.

[Gail]

I always use the three that come on it each side and in the middle I thought she meant I needed 4...BTW I am using my 12x16 Mat. What else might cause it to skew. Mat is sticky, taping it down on 4 sides...Force is 225 and Velocity is 25 and offset is .75. It is cutting all the way through with these settings Oh and can we now set the force and speed on the cutting settings screen in MTC?

[Angel135612]

Try increasing your speed, and maybe lowering your force and doing a double cut if it isn't cutting all the way though.
I do beleive you can purchase an extra pinch wheel from Sherri if you think you need one, but I don't know that it would help. I rarely use three and I haven't had any trouble cutting chipboard. I would do some test cuts, cutting your rectangle smaller until you get the results you want so you don't waste your chipboard.

I did mean a fourth pinch wheel

Will the Silver Bullet one fit a 15" Cougar? That is all I see listed under parts.

[Thyme]

Yes it will fit the Cougar too
