[@GaryEdmundsfromCork]

The absolute genius of these lads. "LET'S MAKE THE LIVE AND NEUTRAL WIRES THE SAME COLOURS!!!"

[@rickmccaskill7888]

Thanks for the video. I have done displays like this and just sprayed black paint on the back of the plexiglass and the engraved a reverse image of the writing and cut out the holes. No need for a second black background.

[@bob2161]

Great stuff! I really like the look of your panel. The edge lighting is quite clever and the light source is doing double duty to boot. I'm happy to subscribe.

[@nerijusmasiulis]

I love how ppls from USA fixing everything with hot glue :D

[@Anton0witch]

slick panel, nice modding :D

Thx pal

[@SavannahGunGuy]

Awesome video

[@PaulFalduto]

Thank you for that video

[@Pahrump]

Can you tell me what kind of crimp terminals those are that you are using? You put them on the wires to the power supply. They're just straight and you can trim them short. Looks like it would take the place of tinning your wires or it will keep the strands wires together and make it one good solid connection.

[@letsfixit1594]

Hi James, They are crimp sleeves for multi-strand cable, they help when you have a screw type connector which has the tendency to spread apart under pressure and dosen´t make connect with the entire surface of the wire.

[@Pahrump]

@@letsfixit1594 thank you!

[@Edubarca46]

Very good explanation. But can you please tell us where to purchase all items needed for this machine update of control panel? I mean the web links. Thank you very much.

[@letsfixit1594]

Hola Eduardo, I will add everything in the description in the next few days.

[@scottvandenhout1796]

What brand / model are those switches i love them

[@AliBenjellounM]

When i added a 50L air assist to my k40 laser i switch on ,it turns on and off quickly by itself, she is no longer working, SOLUTION PLEASE 🥺

[@chrislay4033]

Great video! How thick is that acrylic for the panel cutout?

[@letsfixit1594]

Hey Chris, you can use 2, 3 or 4 mm.

[@MilanKarakas]

Beware, at about 15:40, that small power supply may suddenly burn. I had bad luck with those from BG and two of three suddenly went dead - one silently, another with some cracking noise.

[@letsfixit1594]

Hi Milan, thx for the tip, I have used a few of these and never had any problem and in this circumstance are drawing very little current.

[@ruffledfeathersquailfarm1092]

I notice in your original panel on the other machine, you had blue LED switches for the air extract and water pump as well. On this you have red... Did the others not work correctly or what?

[@letsfixit1594]

Hi Ben, no both worked, it's only the color.

[@ruffledfeathersquailfarm1092]

I was just wondering. Looked like the old panel was 12v switches and the new is 220v

[@letsfixit1594]

Ah sorry! yes you are correct, it was while ago. It was a bit tricky but not impossible to use the led switchers but you would have to use relays so it was easier to use 230v neon switchers for these 2.

[@Zappodrom]

Your Links to ebay are not working - others I did'nt try

[@Fujikatoma]

Why did you use 2 different type of switches ? There is a 10A version of the on/off latch switchers

[@letsfixit1594]

Hi Lars, The 2 switchers for the water pump and extraction fan are switching mains voltage and are rated so, they also have a neon light in them which makes it easier, rather than trying to light an LED with 230v.

[@davidcarter1430]

Hi can you run these of windows 10 or Mac book

[@chiefee5713]

How does the test fire switch differ from the other 3?

[@letsfixit1594]

It´s a momentary switch which basically means when you push it, it will turn off when you release the switch unlike a latch switch which will remain on.

[@chiefee5713]

@@letsfixit1594 is the voltage/current rating any different?

[@foxtrot1787]

would it not have been better to take AC from the back where the two Prong plugs are? I am only asking because that's what I'm thinking of doing

[@ryanlangan1060]

Those plugs are notorious for melting at a very modest current. There isn't much you can use them for. I plan on replacing my plugs and wiring them with a separate wall cord that can support accessories like the exhaust fan, water pump, and air pump.

[@mariogayoso]

Does your k40 cut acrylic in one pass?

[@letsfixit1594]

Hi Mario, I have had 3 different machines and the first 2 would cut through no problem but the 3rd one needed 2 passes on 3mm, have not worked out why.

[@mariogayoso]

@@letsfixit1594 i need 6 passes to cut thri acrylic with mine. Idk why. Maybe I need to do a pwm adjustment

[@letsfixit1594]

@@mariogayoso Check the first mirror with a bit of tape and see if you have a nice pin mark on low power if that is OK check your lens.
