New HDZ & Mount ideas threads needed

Man, coming from Carbide3D that’s harsh…

Actually, I second what Luke said. The cast ones for sure are junk.

And I can confirm that the machined mounts and HDZ designed by Luke are really rather good, I wasn’t sure whether to put them on my machine or in a display case when they arrived.

Got my hdz and 80 mm mount in today. I can confirm. The cast one that came in my key was junk. The stuff from carbide was perfection.

Hell the guy who bubble wraps the mounts uses so much bubble wrap and tape you’d think it was a piece of art inside.

Take care when mounting this, the center screw is for opening the spindle mount ONLY! That screw must be removed when you tighten the mount to the HDZ. It’s not written anywhere and super counterintuitive. IMHO using the bolts that mount the spindle to also adjust tension is a “unique” design choice. Other than that a great mount. Oh and the cast ones are indeed garbage, I returned two, then built my own 80 mm and ran that for a year and a half before getting the HDZ and mount.

:flushed:…is that the input power?

The seller claims it to be 20 Watt output power. Comparing it with my 60Watt CO2 laser, I would say it’s somewhere between 12 & 15 Watt. I tried to get the Amazon link for it, but apparently Amazon no longer sells it.

Almost certainly the 20W is input power. Currently, commercially-available, cheap, single blue-diode lasers will top out at around 5W output power. If anyone has has a link to a more powerful one, please share!

Until there is some technological breakthrough, I don’t foresee this product segment getting much more powerful. The major limiting factor for these small diode-based units is heat extraction. The diode itself is really small and you have to extract a lot of heat from it. Expect that if you use this for cutting at max power, your diode life will be pretty short, like 10’s of hours. Dropping your max power to, say 80% will have a major bump in the diode lifespan, potentially into the 100’s.

And as always, buy good glasses. Don’t go cheap there!

You are correct about the NEJE laser. They list the input power & not the laser power. This specific laser is made by a company called Kunshan. Here is the specs & the certifications for the BX20 that I got.

When it comes to laser, I think I learned a lot from using different products, from a 60 Watt CO2 Laser, to the BX20 20Watt laser in question, to two different laser heads for my Snapmaker.
I can tell you that this BX20 is about 16 to 18 Watt because I successfully cut 5mm of Baltic Birch Plywood in 2 paths.

Ah, but did you say “No, Mr Bond, I expect you to die” ?

Thank you for reminding me. Hre is what the BX20 can do.

awesome, thank you for sharing!

It’s interesting to see that they too utilize multiple diodes for the higher end (double and even triple). I’ve also seen some other mfr’s that have multiple diodes in a single housing using mirrors for combining beams.

For the real output power of 10W, this is compelling. Thank you again!!

Thank you! Do you have an online source for purchasing?

I’m afraid I don’t have any other source than Amazon. I purchased mine from Amazon and I don’t think they are selling it any more. It doesn’t even show as a product that is out of stock. I believe I posted my purchase listing for this laser somewhere in this thread.
