Using a Z axis to adjust the height should be a simple matter, controllable

in the case of aluminum sintering you will have a very small usable depth of

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.

Most lasers using PWM control require a frequency between 5Khz and 25Khz,
then how long the signal is

Greetings,
I am thinking about making a laser attachment for my CNC machine with
something like this:

I am tempted to go with the 130W:
