Feature request: Air assist during laser button?

[Things]

Hey, not sure if you can actually configure this in the software somewhere, but it would be nice if there was a way to set it so the air assist would also come on when you press the laser button. I don't have a red aiming laser, so sometimes I quickly use it to check the laser position, but I'm scared of stuff shooting back into the lens.

it'd also be nice if you could set the pulse duration for the button, for example, you can set it to 15ms, and it doesn't matter how long you hold the button, it'll only fire for 15ms. Also a power setting could be nice too, but not as critical. Just some ideas

I second this, pulse duration could really help when aligning mirrors, another thing that would be really appreciated is a dedicated input for emergency stop, in any cnc machine it's always useful to be able to stop everything in case of disaster, this should stop all motion, cancel the current running file, shut off the laser and the air assist output, and everything should remain stopped after you release the button, right now I have the e-stop button wired to the open lid input, it does stop the laser and motion but if you release the button the job continues and that is dangerous in case you stopped the machine because something nasty was happening, I think I read somewhere in the forum that the 2012 card has some inputs unused, dedicated for future upgrades, and I'm sure it can't be too hard to include this functionality

Hmm, I would have thought the emergency button should go on the main input power to the machine?

I accidentally broke a water barb off my CO2 tube a while back, twice I've had to quickly run over to the power switch to turn everything off because it started leaking water everywhere. Having an emergency button that killed the entire machines power is probably more suited to an emergency

Unless you just mean a soft emergency button, like the laser starts cutting in the wrong spot or something.

the emergency button, i like this subject

the machine doesnt like that abrupt stop does it?

we could possibly have 2 emergency stops, one soft emergency and one hard.

when reset, soft stop would continue with the job, where a hard stop is more like unplugging it safely. now how could you do a safe unplug? is it even necessary?

perhaps it could be 1 smart switch, when twisted its a soft stop, if you hit it thats a hard stop... the mold for that would be sexy

Exactly my point, I've wired the E-stop button to shut the power off but it's not a good idea, maybe for small hobby machines it's ok but that can be scary on a 2x4 meters dual driven gantry servo system, a machine like this doesn't like it when you unplug it while it's moving, I've never seen a single CNC mill, machining center, lathe, etc, that shuts off when the e-stop button is pressed, well maybe the DSP wasn't designed to control such a monster , anyway, I don't think it would be hard to include a better approach to emergency stop for the DSP, just saying...

A soft stop could be wired in series with the open protect switch. The X axis will stop movement and lasing when the door is opened.
