MDF, Smoke, Distortion?

Hello All, I'm starting to mass produce an MDF product which I've previously prototyped. While everything seems to be going reasonably according to plan, I have a few niggles. I'm producing 12-up to a sheet, and often I'm finding that I only get 8 or 9 good items out of 12. The other 3-4 often don't...

Re: Mirror Madness!

Just to finish off this thread, I thought you all might like to hear the punchline. My potential mirror saviours in Rotherham only had 25mm mirrors - but, despite the fact that they were closed, Chris at HPC responded to an email I sent him on Christmas Eve, and sent me a couple of replacement mirro...

Re: Mirror Madness!

Hmmm, okay, here's where things get a little frustrating. If I were HPC, I'd start to worry about my mirror supplies. I noticed that the beam wasn't central on the mirror. This shouldn't be a problem - mirrors reflect all over! But it did give me an opportunity to remove, and clean the cracked mirro...

Re: Mirror Madness!

Thanks guys! Actually I figured this out just before you answered me. Okay, so now I've removed it, I can see quite clearly, the mirror is 20mm diameter, 3mm thick, and has the mirrored side facing the beam. Looks correct to me - and the mirror is quite clean - which suggests to me that maybe this l...

Re: Mirror Madness!

Thanks for the fast responses, Philly Dee & Dave, Agreed - Devon is a bit too far to travel! I'm not 100% sure of the diameter, but I *think* it's 20mm not 25mm on a 3060. Just to clarify, I take the mirror out by unscrewing the cross-head screws at the front (i.e. illuminated) side? (See the pi...

Re: Mirror Madness!

Thanks Dave, Well, by their lack of answer on the phone, it looks like HPC are closed for the duration. Would have been nice of them to tell us their closed dates on the website and/or their answerphone message... :-/ Meanwhile I want to get cutting! Any idea where I can get a couple of suitable mir...

Mirror Madness!

Hello All, Today, at last, I was ready for full-on production tests with my 60 watt 3060. I've done a few minutes of speed and power testing previously, but no serious cutting work. Five minutes in, whammo! The second mirror (that moves along the Y-Axis) overheats and pops! I'm out of action. Frustr...

Re: Unite Lines Aggro

Thanks for these tips, Dave.

I'll try Unite lines again, and see whether there is something that's glitching it. Just a guess here, but I have Windows running in a virtual machine, so it could be that I need to give it more memory.

Cheers!

Unite Lines Aggro

Hi All, I was recently at HPC, chatting about the "Unite Lines" function on Laserscript 5.3. I've been using a 6840 for a year or two, and I avoid this function. Why? It seems to create much, much larger cut files, that take some minutes to copy across to the laser itself. If I have an exc...

Re: 3060 vs. 3050 vs. ...

Hi DaveN, Worthwhile knowing - I was presuming that I wouldn't need a chiller until Spring - but I'll be ready to grab one if the water exceeds 25C. What chillers do you recommend? The ones supplied by HPC, or any? Is their listed 2361 BTU/hr good for more than one laser (with shared reservoirs) or ...
