Just upgraded to a (second hand) Keencut Futura, mainly as a treat for working my arse off over Christmas but also because my original Ultimat appeared to have a few quirks that meant sometimes I had to do things twice.
I appear to still be having these problems, so it must be me rather than the cutter.
First things first
The straight cut is not cutting exactly straight. I cut all my board on here so this is a problem.
Even if I take off the edges to ensure the mat is square, I'm getting a 2mm difference, i.e. A mat cut to 30mm will be 30 one end and 32 the other. I would be so grateful if someone can help me solve this.

Secondly
On all the bevel cuts I get a (albeit very small) scuff where the blade pulls out. I've tried releasing pressure on the mat before lifting the blade out and this helps but surely it shouldn't do this anyway
Many thanks in advance as I'm going nuts
