At 1:30 you say the max thickness for marking or engraving is 1/2" which you later contradict at 1:56 when you note the max thickness is 2". After stating it’s 1/2" you come back and say it’s a half inch for cutting so you may have confused watchers if they’re taking notes.
At 2:05 you state that the kerf is .008" but that should be qualified - assuming yours is (mine happens to be .007" in 1/8" Baltic Birch), you might want to mention that it’s dependent on material & thickness as you’re likely to find that to be true - especially for acrylic & those 1/2" cuts you mention.
At 2:38 you mention a “several minutes startup”. That might indicate an issue with yours or your setup. Mine is usually under a minute from power on to head returning to the home position and the GFUI showing “ready”. I’d also close that section of the video with the head returning - as it is, it looks like the head comes forward toward the center when it’s ready not back to the left corner. Someone might be confused when it doesn’t stop where your video clip shows it.
At 3:55 you show a project loaded but the bed image is of your trace. You might want to reshoot this so you don’t have the trace image on the bed - not sure if it’s the paper still there or just hasn’t rescanned but it might be confusing with the gray elements of the new design for. I’d also either eliminate the cause of the warning that popped up or mention it and explain what’s up with it. I’d also get rid of those two gray filled rectangles. They don’t seem to logically belong to the immages underneath so it may be confusing.
At 4:03 you mention using hold downs or magnets if the material is not flat but you don’t say how to determine “flat” like tapping to find flex between the material & bed, or how to use magnets (including warning not to use too thick a set that might get knocked by the head).
At 4:36 you mention the 3 “settings” and then talk about cut/score/“etch”. Those are operations and speed/power/focus are settings. Further, since the GFUI doesn’t refer to “etch” someone is going to need to infer that the GFUI’s “engrave” is the same as what you called “etch”.
At the 5:50 mark you start talking about GFUI use like placing the design or using the “rotate handle” without any context - how to do that is not necessarily intuitively obvious and you should show in the GFUI how to do these things.
At the 6:00 mark you talk about placing the image in the preview window but your graphic says “menu”.
At 7:28 after you’ve mentioned possible problems like fire or melting (but without mentioning how to deal with them) you remove the piece without checking to see if the piece was cut through. One of the most useful tips is to check that the cutout will come out before moving the sheet (so you can resend the cut operation without disturbing alignment and wasting the material).
Not sure what the written & proficiency tests entail but I would expect this won’t necessarily prepare someone to pass - or if it does, then they’re not really proficient as you’re leaving large parts of the actual execution of your process undemonstrated. I’d take a look at the GF user manual and initial projects to see what they include for instructions on first projects.
Good start though. I train (stand-up class & hands-on demonstration) at our local Makerspace and it’s a 2hr class - I’ve thought about recording a video version for online use but haven’t done it. I think it’s a good idea though after seeing yours.
