I’ve seen a bunch of closed threads on this, so I guess I’ll add my own. Just wasted a perfectly nice piece of medium cherry plywood by trusting the proofgrade cut settings. The back of the sheet barely registered any markings whatsoever – not even close to cut through. Switching to manual shows speed=163. After some trial and error, speed=140 seems to be the correct setting.
- Sheet is flat and held down by magnets
- Crumb tray is clear
- Did not clean any parts, but my GF has seen pretty light use so far so I’d be surprised if that’s the issue
I guess I’ll test first going forward, but it sure would be nice to have some confidence in the PG settings since that’s one of the perks – in theory – of this machine.
EDIT: This thread was closed before I had time to follow up. As instructed, I tried a test print of the standard ruler with default settings on draftboard and got the same results, no cut-through at all. After emailing with support they determined that a warranty replacement of my unit was the best course of action, so I am in the process of doing that. Bummer, but hopefully the replacement will solve this annoying issue. I’m happy that GF is willing to stand by the product like this.
