unfortuna tely just noticed that the laser test fire button is inoperati ve when mpg mode active , kinda defeats the purpose . defeat snatched out of the hands of victory.
I've been kinda offline for a while and likely missed something in this discussio n...

On my stock controlle r K40 the laser test fire button connects to the power supply and bypasses the controlle r, so it shouldn't matter if there's a pokeys or mpg.  The power supply also has it's own laser test button, guessing that just parallels the one on the control panel.  Is yours wired different ly?

Is the loc-line fitting for an air assist?  Is it epoxied on?  I've got the lightobje ct air assist head, but it doesn't work very well with my 65 lpm aquarium pump; I think the air inlet ID is too small for the pump's pressure despite having bored it out.

yes I guess it is .  the k40 psu has two inputs to control the laser , first is an active low digital line to enable/disable laser power
second is a 0 to 5v analog input to control the laser power level. I have the auggie controlli ng both of these inputs. while its possible to " wire or "
the enable line but the analog input would need a switch to be either auggie or manual. I'm sure connectin g the analog signals directly would have adverse effects. at design time I felt it best to just disconnec t all the k40 controls for simplicit y as the auggie laser panel had all the buttons that were needed.
one benefit of the visible loc laser is it makes mirror alignment dead easy.

I have a air assist head to too but I find it makes getting work in/out of the k40 awkward since its so much closer to the work
so now I am now using a 3d printed nozzle  from thingvers e with a nice quiet airbrush compresso r. seems ok
problem with plastic nozzle is it can melt catch on fire if the air is not turned on   Huh
