And an update on the "weak heater" in our 3D printer.  Got the printer
back, they replaced the entire "hot end" so that's the heating
cartridge, the temperature sensor, and the aluminum block they're
mounted in.  I think it's a new nozzle too.

They also did something to the motherboard, it now has an electronic
power fail safety brake that wasn't there before.  Now on power failure
the table lowers slowly instead of crashing down.

The bad news is, it wouldn't print normal PLA any better than before. 
After some back and forth with them, they said they'll only guarantee
their brand of PLA (which didn't even exist when we bought the
printer).  I got a spool of that, prints ok but is a different texture,
limited colors, not translucent, and not food-grade.  But, I guess it
meets the letter of their description that the machine also prints PLA,
just nothing that was available until recently.

So...turned the couch upside down for change and talked my way into a
non-advertised discount on a new printer of a different brand that WILL
print PLA, Nylon, carbon fiber, ceramic, etc.  Got it in kit form to
make it a LOT cheaper.  Sharon will do most of the assembly, "only" 20
hours of labor estimated by the manufacturer.

Unexpected machine upgrades on a budget.
