I have the added “benefit” with the old Stratasys of the print head and nozzle
assembly costing around $1200 USD.
Best way to unclog this beast is first heat it up to near 300C, then feed a
piece of bare, solid 14AWG copper into the extruder. Go slow, so that the
copper has time to heat up.

Gene,
I just went and looked at the Ender3 printer. There is one major
difference between your Ender3 and My Anet A6. Yours uses a "Bowden Tube"
type feed system and mine is direct drive. So on your system, the motor
that moves the PLA filament is mounted to the frame and pushes the
filament

Thanks Jon
I'll head a look.

I want to thank everyone for your advice and encouragement on replacing my
5c lathe spindle bearings.
I was able to replace the bearings in the spindle. The spindle "locknut"
was pressed on instead of threaded on. I had to build an aluminum collar
with steel dowel pins that engaged on the bearing
You can make a double-helical by downloading a left and a right helical and
sticking them together. You do not even need to know what "involute" means
as you just cut and past from McMaster Carr. Just keep faith that they know
how to design exotic stuff like spiral bevels, they do.

Go to McMaster Carr and find a stock gear you like. If they don't have one
you like then Grainger, SPD/SI or Boston Gear will
All those sites allow you to download a CAD file of the stock gear. Of the
CAD file types "step" (or ".stp") is the most universal.
Then you use your CAD software to

3d Printer is working and actually making solid parts, now I need to make

I still say you guys need to print gears on an MSLA resin printer using
a dense high durometer polyurethane structural resin. They'd not only
look like high quality injection molded parts, they'd be as strong as
injection molded parts. Email me an STL and a USPS mailing address and
I'll see what

The theory with printed gears is that with helical gears there is more
material in contact so the stress on the teeth is reduced and that for
plastic we need this extra strength. But what I found is that teeth never
fail. The hubs fail first.
The better reason for helical gears is that they
Module is the Metric version of gear pitch. A google for module gear chart will
tell you everything you need to know. There are also module <> diametral pitch
converters online in case you're using gear design software that only does Mod
or DP but does allow input of arbitrary numbers.
