Laser light not working

Hi

I've just got my BoXZY powered up. I've got my PC communicating with it and started going through the laser tutorial. When I press the Alignment button there's no light coming from the laser and nothing when I press print.

The log showed there's a print head attached not laser. The Etch power settings are at Min 20% and Max 100%.

Please help :(

Update (04/06/2016)

OK guys, so I checked the white wire and when I reassembled I wrapped it around the screw to ensure a good contact but still no laser working. I checked all other wire connections while it was open and all seemed fine.

When I connect the machine to the interface the command still shows the "BoXZY 3D Printer Head Detected" but not laser? Also, when I disconnect the "Quick Change Head" harness from the laser head nothing comes up on the log on the interface.

Any other ideas? Come on BoXZY, please be a bit more proactive on this, as you can tell I'm getting a little frustrated.

Answer this question I have this problem too

Is this a good question?

I wasn't going to admit this and not saying you are in the 'Doh!' camp but did you remove the blue tape from the lens? I was so keen when I first got Boxzy, that I didn't even look!

Do you have a print head to insert? I'd like to know what the log says when you connect a printer head. If not, what does the temperature reading in manual control say when no head is installed?

by

The log says "BoXZY 3D Printer Head Detected" but I'm not connecting a printer head I'm connecting a Laser head.

The temp at the bottom of the log says 146°c for the extruder which is odd because I don't have the 3D print head.

by

Ok, one last test. Carefully unplug the harness from the gantry itself (the second harness, don't attempt to move the machine while it's unplugged). After doing this does the temperature read -26C with the laser removed? Does it also read -26C with the laser plugged in and installed? Let me know what the temperature readings are for both circumstances. Also, what does the temperature read with no head installed and only the primary harness installed?

by

Hi

So with the machine on and interface on with the laser connected the log says "3D Printer Detected" and the temps shows 146°C

When I remove the harness as you said without moving the gantry the temp drops to 27.5°C. When I plug the harness back in it goes back up to 146°C.

When I remove the Laser head the temp drops to 27.5°C and the log doesn't say anything about the head being removed. When I install the Laser head the temp goes back up to 146°C.

??? :)

You may want to look at my breakdown of the laser module and the cooling issues it has.

Awesome information Gary. I am looking forward to opening my laser back up and making these modifications! Right on.

Updated with much more detailed information about the oddities of the interface.

Wayne,

If you shake the laser head is there a sound like a wire loose inside the cannister?

You may have the ground wire off.

Hi guys

Thanks for the replies.

I've taken off the tape from the lens, I even had to double check :)

I've just tried shaking it and nothing is rattling about.

When you plug it in and press the Alignment On button, does a fan turn on?

by

Hi

No I can't hear it.

by

Definitely no fan coming on.

Does it detect that the laser module is inserted?

by

+1 on the the question about the laser detecting. There is a "toggle log" button in the interface, or a log will already be visible at the bottom of the page. This can be expanded by pulling the top line upwards. When you insert the harness into and disconnect the harness from the laser, does it say "Laser head detected" when the harness is installed and then "CNC head detected" when removed?

Mine stopped working after about an hour of use. I opened it up and fixed it. Maybe yours has a similar problem? See my answer on that thread:

Though when mine stopped working, the fan was still working... Nevertheless, I would suspect that white wire that should be grounded inside.

Cheers James, I'll have a look at the PCB board too. :)

Hi peeps. Sorry for the delay in getting back to you. I have a new Arduino board supplied by BoXZY which seemed to solve some of the problem.

I now have the interface confirming the Laser head is detected, the fans now come on but there is no light coming from the laser when I turn the Alignment on or when I print. I've opened up the laser head, checked the White wire and all other connections but all is snug.

Any ideas why the laser wouldn't be coming on?

Thanks

Have you removed the tape that is placed over the lens? I know it's almost insultingly basic, but it's been missed by some of the best. If that is ok, verify your 3D printer fan is working. That will let me know if anything did get damaged on the main board vs a laser issue.

by

Hi JH

Yes I did lol. I eve double checked myself after trying to get it going.

The fan is coming on full blast too and the interface confirms the Laser head is attached and when removed it then says CNC head detected.

by

Can you specifically tell me if the fan control on the 3d printer head is working? It's diagnosic to the board itself.

by

I don't have the 3D printer head. Just the laser and Mill

by

Ahhh. The laser was thoroughly tested before it was sent. So Im confident you have a damaged transistor on the main board from the earlier incident. If you're comfortable with soldering its a quick fix. If not, I'll ask the team to provide a new board for you to replace. Would you like to fix the individual component or swap the board?
