I don’t quite get it. “Open MO Delay: MOPA permits a wider frequency range comparatively to Q switch laser types, and this delay allows you to adjust this fine control.”
What does that mean? I see Start TC and End TC move the start and end points for each feature on a raster. So I have perpendicular vector lines as a reference and tweak the Start/End to make them line up.
Open MO Delay seems to add a delay to both Start TC and End TC, moving the raster over. But if you did need to move it, the same seems achievable by adjusting Start/Stop.
What’s MO actually about, and how do you adjust it?
Never messed with it but I will. Issue I get with start and stop TC, it moves the end of the line but (in my case anyway) I get a skinny start and a matchstick stop. I can move the end but it still is skinny/ matchstick, just further right or left. Makes sliced fills visible on X table .
Motor Output Delay, huh? Never heard of that before. When I get a chance I’ll play around with it. Might help with slice performance, maybe get rid of the matchstick head at the end. I even put in a feature request for overscan on fiber.
I found some references to it in JPT’s software manual:
"
A: System initialization time: can be received input signal after 12 seconds of power supply.
➢
B: MO and PA signal delay time: range(8ms-35ms), recommend 8ms.
➢
C: When the light is switched off, the length of PA before MO is switched off: ≥0ms.
➢
D: Frequency sampling time under internal frequency mode, at least 1 complete frequency period before turning on the laser ¶.
"
“External frequency: When selecting external frequency mode, the laser output pulse will be synchronized with external frequency signal. If the control card has optimized the external frequency signal, this mode can be used.
When this option is not selected, the laser will use with internal frequency mode. And the laser will calculate external frequency signal in MO and PA delay time. Default setting is internal frequency mode.”
Presumably MO is Master Oscillator and PA=Power Amplifier. But I don’t have any further explanation of what either signal is about
EZCAD manual:
" Open MO delay：The MO signal gives the AP signal after the delay. If the setting is too small, it may damage the laser.."
There was no reference to an “AP signal” either. Probably a different way to translate “PA” for Power Amplifier.
A generic Chinese laser manual
" After selecting fiber, the type of fiber laser will appear in the right, for example, ipg, ipgm, quantel, raycus, and the corresponding frequency range and MO delay will appear."
