Given the two laser control panels and the design comparison, what's the actual goal here?
The first goal is functional: I need to add a number of new control and status functions.
Second: I am a vain man, and I want this tool to look a little less hokey. Not entirely, just a little. I mean, I gotta be me.
The biggest addition will be a software control for the laser. I somewhat arbitrarily decided to go with a rebranded Anywells controller from LightObject-- I'll find out later if that was a good idea or not.
The huge, spread-out, not-calibrated-to-anything digital PWM laser current control gets replaced by a thumbwheel implementing a Kelvin ladder. And instead of a 7-segment LED display that simply goes from 0-100, I'll use a good-old analog meter that measures actual milliampres.
While we're at it, a matching analog meter reads cooling water temperature.
Like on the American control panel, the key switch is the only power on-off, and the emergency stop will be a real immediate-stop interlock.
I have an onboard air assist, so that needs a switch too, along with a lighting switch and two switched laser pointers, one a centering beam and another for focus.
And, why not steal the tube runtime meter from the nifty panel as well? :-)
Last of all, arrange it in a more 'American' style: functions grouped together, consistent labeling, and no angry color salad. And just one or two inside jokes, because the tool is still a bit hokey.
