General Discussion / Getting better at 3D printing

Just messing around

Just thought I'd drop my eBay auction for a mint conditions MatterControl T10. I know a lot of us laser-guys are also into 3D printing.

I'm looking forward to see where you take this. If you need some extra help on any given task, I'd be willing to. Even if it's as simple as proofing a manual or testing use cases.

Welcome aboard. There is so much to learn here. :)

My cPanel website stats indicate that we get about 4 times the number of page visits from unregistered users...so this means, roughly, that with our 500+ registered users, about 2,000 visitors are just looking around and reading and have not registered.

Wow!

Bob, very much appreciate your elaboration of the project. The more folks that get into these laser engravers, the better.

If you make it "close" to your fund raising goal, will you continue via kickstarter (or possible via another route)?

If you do get close and need more backing, I may have some funds to throw in. I think this kit will sell to a lot of "less technical" people than many foks that have posted in this forum. (And to lazier folks, like me.) May be keep the forum updated with your progress and people we haven't heard from on here already would be interested. I think only about 20-ish% of our members have ever posted.

Best of luck with the project!

Yeah, I'm not going to fund the project, it's too much $ for what he offers. It is nice to see that someone has recognized the need to improve these machines though.

(Of course, we all recognized that already.)

What Can Be Cut? / Re: Materials that I can cut

I have the 5.5, so not certain from firsthand experience, but my 5.5 cuts through cardboard easily at much lower power.

I use the CO2 for cutting, and the diode for engraving.

So for the CO2 I run the G-Code from T2Laser but generate it with ArtCAM mainly because that's what I use for the CNC router, there's no real reason I could save the DXF out and import to T2Laser and use that for everything, rather than doing the same thing with the G-Code.

I'm very close to scrubbing the stock firmware, installing firmware/params from T2 and slogging through the GRBL settings. The included software is as bad as benbox's.

I appreciate your feedback Zax (as always).

I have vector cuts and vector engravings working beautifully now.

Raster in gray-scale has been elusive. I can burn a raster, but no matter what, it's goes black and white.

@Zax - which software do you generally use on your CO2 machine for grat-scale? I want to eventually use T2, but not keen on figuring out all of the GRBL parameters right yet.

Yes I thought that as well..but they said they used LASERply...but then there is a lot of good quality ply sold, that is not PROPER  LaserPly...especially on Ebay. 
Proper Laserply has totally different  glues to bond the veneers unlike ordinary, but good quality Ply.

I'll have to look into the vendor - it was from Amazon.

Zax, do these laser machines also use GRBL-based  firmware. i.e. can I get T2Laser working on this with some modifications to the GRBL parameters?

Yep, we set the plywood on a couple of bricks and the scorch is completely gone. Although I do thing we can speed it up and drop some power.

I know Zax has experience with the cheap CO2 lasers.

My brother just bought one and we're trying to cut the planetary card as a benchmark piece. Acrylic works beautifully, but with 3mm laser ply, we get a very gummy scorch. I've attached a couple of pics. We did this one at:

50W laser
5 mm/sec feedrate
80% power

We get a full cut in a single pass.

As like most of these machines, it has an air pump  to quell flare-ups and it also exhausts smoke/fumes to a hose that is terminates out-of-doors.

Any advice to reduce this scorching will be very much appreciated.
