Ok - so I put this in the “beyond the manual” category because it involves both the BETA ‘calibration’ process, and subsequently use without the crumb tray. If anything belongs in this category, I suppose it’s this.
So - Calibration successful. Amazing, actually, using ‘medium draft board’.
Now to pull out the crumb tray.
Wife tried earlier using math to do one of those (everyone got them, right?) JDS engravable notebooks for our nephew who is graduating HS this year…
My crumb tray measures, for all intents and purposes 34.7mm tall.
With a 25mm riser (tray made from boxes.py / outside measurements…) the stack is 45.05mm.
[stack height]-[crumbtray]=material thickness.
So - She tried using “set focus” (material type ‘unknown’) and it was pretty borked… not at all in focus. imagine ‘defocused’ by half almost… looked pixelated almost.-
Tried a second time using math - 10.3 mm material height. Part of the engrave was almost dead on, but at the bottom it was at least 10mm ‘low’ from where it was on the screen (the pink outline we all love…)…
FYI- she’s tried these before, using our math, and not had an issue. It’s just not working to choose ‘set focus’ with unknown material, and, using the math it’s way off…
Is my math wrong? Do you have to choose a material for Set focus to work? I’m going to try something in a few using ceramic tile holding up a plywood scrap to get the same height. At cents vs 6$ it’s a better material to try on…
Thoughts? feedback? my math sucks?
