I'm looking for advice on gear cutting. I've got a low-end harbor freight
mill with a 4th axis added (actually a rotary table) and I want to cut some
module 0.5 spur gears. I know that the smaller the gear the more precision
is required.These need to be as strong as possible too. They need
oops- meat to reply to list
offset-scale is set to appropriate (well) value (if not,
eoffset-request stays 0 (guess how I know)).

Did you set any input on the *axis.L.eoffset-scale *pin? May that's what

El mié,
Just to clarify.. To rigid tap you been a b and z...

I've done this a few times. PVA is best used if the mold is new. You can
spray in on the mold using an old spray bottle that used to hold kitchen
and bath spray cleaner that is well rinsed out. But after the mold is used
a few times mould release wax alone is OK.The PVA has some tiny film
Howdy folks,
Placed an order with MSC Direct this past weekend for some end mills and
reamers. One reamer I really needed was a .156" 4 flute. Either old age,
bad eyes, or a combination of the two, I selected a .0156 4 flute reamer.
Package arrived yesterday, and I realized my error (which has

Pretty darned good Sam, definitely worth pursuing. With 2 bearings
This is the best and most durable DIY drive I've seen. One
improvement for the future is to make the internal tooth gears from
something other than 3D printed plastic. Perhaps you can cast them in
epoxy and fiber composite. If you used a timing belt as part of the mold
the cast teeth would be
Hello Lloyd,

I'm having trouble getting the new 2.8 external offset functionality to
play nicely. Most of the (known) steps are working (as observed in the
hal watch screen):
- axis.a.eoffset-enable is set true.
- inputs (step up & down) generate appropriate values in
axis.a.eoffset-counts
- offset
another update - at 1/2 step - the discrete resolution should be about
40,000 divisions per rotation. .009 deg.
