Hi Aram
first look on the small gantry looks like this kind of gantry is only
suitable for pick and place applications, because this construction
is as we here called a lamb tail.
For cutting foam could be feasible, but for cutting more than wood

Hi EMC2 pros
I was using 12 years IBH CNC: http://www.ibh-cnc.com
They had so called Parameter sentences.
A parameter sentence was always one Line, and startet with a star,
for example:
*N10 P43=4000
With this lines you could perform simple math like *+-/, sqr, If,
goto etc, you had about
Cool!
(I should read the Manual ;-))
Thanks anyway for telling me this feature.

Hi Aaron
like in the Wiki described, about 500 MHz are O.K. my experiment with
slow computers are:
450 Mhz PIII with 512 MB RAM: Installation works (256 MB RAM failed
to install), takes time, Simulation O.K., but Halmeter and other
diagnostics painful slow.
1.1 GHz AMD, 512 MB RAM works
, as operator.
I think, this functionality could even be implemented in EMC, but not
as a dummy programmer as me ;-)

Hi Marc
I was working long time on an six axis gantry laser system with about
2.7 to 1.8 meters travelling range.
As I understood from the machine builder, they used also two
independent servos fore both gantry sides, one was the master
servo, and the other was tracking to the master. Both
Hi
The system builder also tried the way with an shaft.
He said you will never get the desired accuracy and dynamics, but for
an plasma cutter, this may be not the problem.
The gantry was about one metric ton and accelerated in 300 ms to 30 m/
minutes!
Only the servo amplifiers costed me over
