Have a look at this work. Maybe a good solution.

What's wrong with using proven, production-style databases that work well
large or small? MySQL and postgresql

Possibly.
The real work is in working out everywhere that tool data is used, and
when changes get committed back to the DB.
The details of the storage can be decided later (if sqlite proves to
be not ideal).

This would work if the query language was 100% identical. I don't know
if it is.

If you can't fix it, you don't own it.
With MySql you need to install LAMP and with postgresql it looks like
you have to have a server running and create a user that can log into
the server or something like that. Sqlite requires non of that. I've
used MySql for web based PHP applications and Sqlite for local Python
applications.

Hi,
I'm facing a slightly unusual problem and before I head forward into the
wrong direction I'd like to hear what you think about it:
I have to pan a laser scanner (a single rotary axis), so I thought about
using a BLDC (which I happen to have already), a MESA 7I39 BLDC
controller and a

So, first question: Can I hook up the 7I39 to a BeagleBone Black. Well
of course I can, but is this somehow supported already, so that it is

Hi Andy,
thanks for you comments.
Alternatively the Pico PWM brushless servo amp only needs a single
channel of PWM:

I think this could be done as a geared solution, if you could work
from a phase locked (to 50hz) clock at some higher rate, and use that
as the encoder signal, and the 50hz as a trigger to g76 with suitable
parameters it would then be synchronised and have a flyback (gate the
laser off then), or

Not as far as I know.
Or perhaps the better answer is not yet.

Hi Dave
I think this could be done as a geared solution,
Of couse, I forgot to mention, there will be a reduction gear about 1:50
or 1:100, the motor is not very strong and the scanner ways about 5 kg
and will be mounted eccentrically, so it will create quite some torque
and inertial mass.

Not directly. For multi-start threads you offset the starting position.

Hi Andy
Not directly. For multi-start threads you offset the starting position.
So two G33.1 calls at the same position and with the same parameters or a Z
offset of an integer multiple of the pitch will cut the same thread. In a way
the thread starts always at 0°.
See you
