Cutting issue and force setting

when using quick print i normally used a force of 105 and everything was perfect. today i seem to need to use a force of 240. I checked the knife and it seems good. what would make the difference and is it a problem. could it be that the spring is stretch?

thanks

Sounds more like a chipped blade to me. If you have a new blade, pop it in and give that a try. You can also look at the blade under a magnifying glass and see if it is chipped.

When I first read your post, like Steve I thought it was a chipped blade.............but after you said you checked the blade, I didn't answer.

I keep 2 separate blade holders with 2 different blades. One I use for general cutting, the other I use for laminated prints and detail cutting

For me, the cost of the extra blade holder was well worth the time fussing to get the settings correct every time I need to switch.

Not saying that you shouldn't ALWAYS do a test cut...........but having the 2 blade holders gives me a dependable starting point with each blade.

Great idea about the extra blade with the holder. That would save extra time! I need to get an extra one.

Here's something funny about me and quick print, The first week after the machine was installed I was messing around with it and couldn't get QP to cut unless I turned the force up to 200+ I called my rep at Imprintables and he said 90ish should be the max setting, so I ordered another blade thinking I screwed mine up already,"short version", I had the QP in upside-down and was printing and cutting the plastic backing, flipped it all was well. I don't have many ego problems so ain't afraid to tell anyone. But "Won't do that again" I hope""

The standard 45° blade, if you want to cut heavier materials like anything close to .030 you go to a 60° blade, all that stuff is on the site just go up to the upper right hand corner and type in a keyword, there's a ton of info from past questions available there, also the RolandDGA site, lot's of good stuff there also. I live about twenty miles or less from you if you ever have a question or I could help you with something.

Interesting. I keep a record of blade force for each blade installed in our SP 540i. With a new blade, the force I need to clean cut Quick Print is generally between 35 and 40 gf. By the time I get to 105, I'm thinking about replacing the blade. When the blade force gets above 100, I generally notice that the cuts on Solutions Opaque and Clear become more ragged instead of clean.

I used to keep one extra blade as a spare. The problem is that even the spares can sometimes chip. Now, I keep several on hand; they don't go bad.
