Hello! I’m sorry to trouble you, but I haven’t found an error exactly like the one I’m getting: a “this is not a proofgrade material” error on proofgrade materials.
Here’s the summary:
-
From out of the box, (February 15, 2019) I have been getting the error. (A) I poked gently at the problem, but as the cutting, scoring, and engraving was working fine, I assumed I must have some esoteric setting wrong that was throwing a false error.
-
Occasionally, it would not be able to read the qr code in the bottom right, so I followed a suggestion on the forum to make proofgrade tiles, and put it where the camera could see it. (B) As you can see, the 'forge does indeed register it as a proofgrade material.
-
In the beginning of April, 2019, I was beginning to have occasional trouble cutting all the way through the material. Again, I thought it was user error, and after reading the forums, I ordered a set of magnets(C) to hold the material flat. It improved some of the cuts, but not all.
-
Today, May 5, I can’t get any cuts to go through unless I change the speed or tell it to do a second pass. The second passes are leaving a lot of char, and even losing a mm or two of material to charcoal. (this is new.) After poking around on the forum, I didn’t find anyone else having this error, but it seemed to be related to focal length/material depth, so I decided to check the settings AFTER I hit the print button. Before I hit print, the focal length is at .13, which is the proofgrade setting, I believe. After I hit the button, and the machine does its own measurements, the focal length clears out to a greyed ‘auto’, and the non-proofgrade error appears. (D)
I’ve tried the teal button reset maneuver a couple of times now, and I did the “pull the plug to clear the caches” error to no avail.
Any ideas? Thanks in advance for the help.
Edited to add: I did all the cleaning steps multiple times, both the lenses with Zeiss wipes and the crumb tray blowout with canned air, and cleaning the box itself.
