Hi
I have question about using M codes.
How to use M62 - M65 m-codes to set parport pins from program ?
In documentation is: /The P-word specifies the digital input number/
How to connect it to parport pins ?
how to use M66 to read digital input (pin from parport ) to control
program ?

So the short message is: Keep your hall effect devices scrupulously clean.

Check out something like a Honeywell 1GP4001. They are in a sealed can with
the back bias magnet. Digikey has them for about $7. There are other
models and more expensive housed models also. Some are good down to zero
speed, some are not. I can find out more info if you like. I design speed

I believe that the greatest hurdle in constructing a small CNC machine is
the cost of the linear slides, and I've been trying to think of a way to
alleviate this, and come up with a 'Pivot Mill'. While this is robotic in
configuration, it is for all intensive purposes intended to supplant a

A few thoughts...
Isn't the Z axis the easiest? Instead of the dual strut you could use a
pantograph, which would keep the Z motion linear instead of radial. It would
still be a sine conversion, but it simplifies the conversion significantly.
The conversion itself is different matter. Others
What an interesting looking machine.
We have a demo of a similar type of machine, called SCARA. In emc
2.2.2, you can run the sample configuration scara/scara.ini and see a
visualization of this machine on your desktop. Screenshot here:

I think the hardest part (other than creating the kins) is dealing with
backlash. Creating rotory motion without backlash, to me, would be a lot
harder than with linear.. Spring load them all one way? double sets of
gears forced against each other?
very cool though.

It's a SCARA. They are very common for pic-and-place machines but one
of our guys a few years ago wrote a thesis while building one and
testing it for stiffness. I believe the guys was from India. The
current SCARA kinematic files are based on his work. Shouldn't be much
of a problem to
Oops. One additional thought, while the tool will always be
perpendicular to the work surface, the z kinematics are not trivial
either. But in that case I think you can use an Angular definition for
that axis. You'd just have to work out the motion in and out along the
axis of the forearm

I want to use UBUNTU with dialup modem. i have book about UBUNTY but i
getting massage it not set. maybe driver for modem?
i use ASrock motherboard and generick modem that i put into PCI.
that is all
thanks
