Summa cutter - flex cut


New Member
I'm using a Summa cutter to do some circular cut decals. I'm printing onto a 6.0mil thick vinyl stock. Can you someone give me some suggestions on how to setup my Summa to Flexcut the decals? I currently have the blade set with a 1/4 clockwise turn and the Flexcut set to 350g. Increasing Flexcut to 400g doesn't seem to help much.

Are there any other settings I need to set to get a nice clean circle cut? With my current settings, the decal does not punch out easily and there are also some unclean edges.
Any suggestions?

New blade, proper stick out of blade then play with the settings. 400g is way too much pressure. I'm dialing in a new CleanCut blade. Kiss cut is 75g and FlexCut is 90-95g.

There is no silver bullet. You have to spend the time to dial in your media, blade and machine.

Recently there was also a lengthy post on this.
