Hi o
I just went through integrating EMC2 for a 3d ABS/PLA printer
Its detailed here:

The control boards have their source files and pcbs listed, i;m working

It states that those power supplies can be controlled from a TTL PWM, so I
assume that it will be easy to control from a standard parallel port with HAL
and LinuxCNC. Is that correct?
It _should_ be, based on the amount of information provided.

Dave,
I'm not sure that all of you guys on this list are aware of the fact
that the US has introduced metric units since a long time.
In 1866 Congress voted for the metric system, and in 1894 again
administration passed bills in that direction. Only in 1975, President
Gerald Ford signed the

As the printer is a SCARA arm
This is an interesting development, as it has more printable
components than a conventional RepRap. You could (in theory) print the
arms, whereas

My thought was to change the focal point as material is cut. I understand
that these lasers have a very narrow depth of field when focused sharp enough
to cut metal (or even wood). So, lets say my focal length is 0.05 inch, each
pass I could move
Hey Peter, Hey List,
I wrote my standalone pyvcp panel which runs with halrun only for my lab
setup and everything looks good at this moment.
I ordered the 5i25 and the 7i77 together some weeks back. Not having the
correct firmware does not matter, since I now know how to program it anyway.
So
Jeshua,
It states that those power supplies can be controlled from a TTL PWM, so
I assume that it will be easy to control from a standard parallel port with
HAL and LinuxCNC. Is that correct?
Most lasers using PWM control require a frequency between 5Khz and 25Khz,
then how long the signal is
Hi Jeshua,
I spent a number of years feeding a Trumpf 4kW industrial laser. It has been a
while but I'll dump what I know.
1. The output of the laser beam changes width as it exits the laser tube. The
industrial machines use a patented fixed length beam delivery system. Think of
this as a
This link is for a reprap SCARA: http://www.youtube.com/watch?v=Cquw7dvR80A
There was a conversation a while back about how many plastic Yoda heads and
other fast prototyped plastic waste would end up in land fills. I see the
above reprap SCARA being a positive and constructive engineering use
