I just purchased a Bostomatic BD18-2 from NASA JPL. The servo amp's for all 3
axis were missing. I'm trying to find new amp's and information on the machine
so i can make a linuxcnc conversion.
The motor is this glentek GM4040-41 180vdc, 9.1A. I decoded the serial number
it has no brake, no

Thats why I bought a BS-1, John but I'm only about $250 into motorizing

This may well be a dumb question Gene, but given you have the machine shop and
CNC couldn't you make the gears etc yourself out of metal?

Greetings all;
And I can say without fear of contradiction the openscad IS the problem,
I am current about 2mm up of a print of the outside gear of the drive,
and the teeth are 100% filled and very well formed so far, its the best
rendering I've seen on the build bed yet, so much better than

I modified some python code that is in the linuxcnc tree (author.py) and made a
slicer post processing script that takes the generated gcode and converts line
segments back to arcs.

Hi all,
I made my first attempt at using spindle synchronized motion for a rigid
tapping operation on my Bridgeport BOSS mill today and it didn’t go as planned.
It has a spindle encoder and a Pico USC board. I can use the spindle to read
encoder counts and spindle position (I already use

I have never used OpenSCAD. But after a bit of a Google this might be

No, it is extremely limited.
Cura is about the best slicer out there. I don't think that
reinventing the wheel is going to help with the

It outputs SVG for a DLP, so isn't particularly useful here.
And it is a VB Macro for Inventor, so I doubt anyone

STL is a set of triangular facets. There are no curves for the slicer
to make G2 or G3 arcs out of.
If
Gene
do you want to convert a series of short lines that approximate arcs
into g02/g03, to save space?
Or, described as 'fitting x y pairs to a circle'?
Dave E was looking for similar ( a good while back) and I didnt find any.
If you have slices that can be processed in scripts with

If its tall enough to flex. This PLA seems to be pretty fragile cold.
