I could use a little assistance. I just replaced the stock control panel with a new acrylic panel so I could add my glcd and generally make a cleaner layout.
However now I can’t get the laser to fire. I’ve verified that I’m sending a voltage to the trigger on the power supply but I’m not getting any current passing through the ammeter.
I’m not sure where to check for issues and dont’ want to jump the wrong pins with my multimeter looking for something and causing a bigger issue.
And yes the laser wire switched from yellow to green. I had to extend it about 4" and green is what I had on hand.
Make sure you have the interlock circuit closed (Jumper across the WP terminals, not sure how theyt are labeled on some supplies, mine is wp) Without that circuit being closed, it will not fire. The laser enable button should be in series with that loop.
The enable switch is the only switch on that circuit and it does open/close as expected. This was working 100% before I moved over to the new panel. I moved one switch at a time and wire for wire to be sure they all went back exactly.
I get my trigger signal from the smoothie (1 wire setup) but it’s like it’s just not firing the laser circuit.
Ok, so this is messed up. To get it to fire I have to press/hold the test fire button. So what got messed up that the test fire is now required to fire under a G1 command.
There were 2 buttons in the original panel, a laser enable and a ttest fire button. Laser enable is on or off, the test fire was a momentary contact switch. Sounds like you put the wrong one in your new panel. Make sure the enable switch is the on/off one and not the momentary one.
nevermind, I’m completely brain dead this morning. I was forgetting to issue the M3/M5 commands when I was test firing from LW3. False alarm and everything is working perfect.
Lol 
glad you got it sorted out. NICE looking panel BTW
Very nice panel…
Thanks on the kudos on the panel. It really does clean it up.
I need to learn not roll out of bed on a Sunday morning and immediately go into the shop to do things that require thinking. I wasted entirely too much time simply to miss enable and disable codes.
What did you use to design your front panel?
@Kirk_Yarina I drew it up in Inkscape and did the engraving and cutting with LaserWeb
Nice design. I’m planning to make something very very close to this. I’m just going to add a SD card slot. Also did you think about using clear acrylic? So it covered the LCD? I’m just going to back paint the other areas of the acrylic.
Also how much trouble was it to remove the GLCD dial? Is there a hidden screw or something?
Most dial knobs on the Glcd are press fit.
That’s impressive! My mental picture (never done one) was spray the back’s base color, reverse engrave the lettering, then respray the contrasting color. Time to rethink that…
It is how I did mine @Kirk_Yarina https://plus.google.com/+AnthonyBolgar/posts/A7ppkR1EgBY
@Bill_Keeter The dial on mine is just a press fit as I imagine most of them are. Hopefully whoever assembled yours didn’t glue it on since that knob really does need to come off to panel mount it.
@Bill_Keeter Also regarding the clear acrylic, I really wanted to use what I had on hand and it was either this or pink Since it’s right next to my CNC, I may consider putting a thin piece of plexi over the display and just secure it with the standoff mounting screws but we’ll see how it goes.
@Carl_Fisher would you be interested in sharing your file? I have a c3d board on order and have the same parts you do and will have to get the face-lift ready. 
Sure, let me do some tweaks to the file and I will upload it in the next day or two. You’ll have to mark and hand drill a few mounting
holes though because I don’t know that every panel is the same.
