Hey Chad,
Thanks for your reply.
The mirrors are not stepper driven.
We have a head from scanlabs, something like this :
http://www.scanlab.de/index.php?id=17919It is controlled by 2 analog voltages wich relate to there position, i.e. 0V on axis1 completly to the right and 12 V would be at your leftt side. 6V would point to the center of the field.
Actually it might be that the electronics inside the head are closed loop, but when controlling with the normal program, there are settlng times (like 0.4 ms).
what i wanted to do make a program like this
G0 X10 Y10
G04 F0.4
M10(laser on)
G1 X70Y50 F400 (in mm/s)
G04 F0.1
M11 (laser of)
This is comparable with how the galvo's are controlled at the moment. (i took the liberty of studying a dissasembly of there driver, i can read, but i cannot create ... damn).
Do you know if a G04 with just 0.4 ms could work?, or does that get rounded to 0 or 1 ms
To pulse the laser there are even times like 40µs, but that i can solve with some extra hardware. ( a custom timercard)
Kris.
