If I understand the cooling even a little, ambient temp could make a huge difference to running time without cooldown, because the efficiency of cooling is (mostly) proportional to degrees above ambient. With peltier a different number of degrees, but still. So the tube isn’t going to increase its temp at a constant rate, but at some kind of rate that slows the hotter it gets (relative to ambient).
If ambient is low (60s-70s) you might be onto the nearly-flat part of the temperature increase curve before you hit maximum operating temp, but if ambient is high, you might still be on the steep part of the curve.
There are probably gf’s that are instrumented to measure that temperature increase under various conditions.
By the time you get your production unit, the tube will match the product you ordered.
We’ve actually kitted a number of prerelease units with a few different features of Pro units so that we can ensure they work.
No, building machines configured-to-order is a whole different thing; our line isn’t set up for it. It’s just a way for us to validate some of the suppliers, equipment, and materials in the field.
Like anything in the manual, this is subject to change. Lots of testing going on that may adjust these numbers.
Ok, so it actually almost made it. We just won’t know if you have a 40w or 45w tube.
In theory then, I wonder if 16mm or even 18mm could be cut in 2 passes. Is that something you could possibly try if you have some of those thicknesses in hardwood lying around?
Not sure if 2 passes causes more charring or messes up the cut edge (anybody know?) but being able to cut those thicknesses, even on the small GF bed size, opens many more possibilities.
I don’t have a Pro tube for sure. Mine was one of the first prereleases. Two passes in wood gives wider kerf at some settings. The small set of squares I cut in oak shows that in the far left square. I just havent bothered much beyond 1/4 inch which it does make it through in one pass for walnut.
Yes being a Brit old enough to remember decimalisation I can still cope with inches, pints and pounds, etc but I never use them for anything technical. I get drunk with pints of beer usually but sometimes with litres of wine.
Fahrenheit doesn’t mean much to me, especially when outside of normal room temperatures, like melting plastic.
