Re: Yellow is not mellow

I suspect you don't have enough air going into the bottom of the oven to help force the material to burn correctly. I had that problem recently. I have an airline from my compressor going into the underneath part of the oven with holes drilled into the oven floor. I usually run 7 psi of air into the...

I agree with you on that... I also find it hard to find posts that I have seen just the day before and wanted to come back and post to.

Re: Long Time Lurker With A Print Issue

Actually, A sanded surface helps adhesion Just a bit better then the red anodizing.I tested both ways when people where trying to say aluminum was causing defects in casting. Exposed aluminum poses no problem. Sanding does 2 things... improves adhesion slightly AND shows you where the table surfaces...

Re: Long Time Lurker With A Print Issue

Get the new stainless build plate and eliminate that part of the equation.
You can sand your original plate which will help adhesion... I reinforced mine with a thick sheet of aluminum on the inside of the platform... then sanded flat...

Re: printing test not working

Not sure about the color wheel,
but if the tiny glass filter on the inside of the casing is broken, that is the heat shield and That would definitely cause some problems. Attached a picture . That is a tough part to find.

Re: printing test not working

If it's a new lamp and you have to go to 1.6 msm, I suggest the lamp is weak and to call their tech line.
Some lamps are weak for this type of operation and won't last long... also, the higher the msm, the longer the print time!

Re: Having issues with Emerald resin.. Better luck with B9 Cherry

The statement made way back that raw aluminum was causing issues, which is why the vats were anodized, is not true I have run all the B9 resins in a plain aluminum vat that was never anodized without issues. My platform is sanded aluminum. I suspect that the issue is caused by curing and possibly cl...

Re: Upgrade from b9creator 1.1 to 1.2

Actually, it can be done... I converted my first b9 1.1 into a 1.2 and I also bought a 1.2 and assembled it. Both are running fine. Converting the projector is not easy because the casing of the 1.1 is not exactly the same... If you can do that, then you also have to buy the 1.2 Z motor and rod asse...

I was getting the AO61 about 50% of the time on both my printers. I have tried suggested solutions, but it does not seem to fix it permanently.Essentially what I do now, when I am ready to hit the button to print, I do that. If the green light does not start to blink within 3 seconds, I manually pus...

Re: Curing question

Yes, I would do that with 1 sprue and a vacuum rod attached at the very top.Then Vacuum the flask before casting
Over sprueing can also cause problems and it's a lot harder to remove all of them.

Re: Problem in printing

I would suggest adding a piece of folded paper between the black arm holder and the Stainless plate on the side that is not making good contact. Usually if a part of the calibration print is not sticking well, it is caused by a small amount of alignment problem. Putting a small piece of paper on tha...

Re: Curing question

If correctly cured and burned out, I would cast that with 1 sprue only... as a safety , I would add a vacuum rod to guarantee that the cavity is perfectly clean. I started casting resins many years before I had any printing machinery... as far back as 1987. Started casting in 1964 and burned out any...

Well, Here are the answers I come up with...

Re: Curing question

If I could see the casting and it's problems, I could probably explain whats happening...
Can be caused by many things... Inadequate Sprue, Sprued in wrong area for casting of that style... Need a picture.

Actually, thats a bit too much build lines... I suggest putting a light grease or oil on the Z rod. this will help it run smoother. If the z rod is not turning true and is going out of round a bit, then fixing that will help. I made a simple holder at the top to hold the rod straight. Try printing t...

Re: are the core 530 and 550 adjustable XY?

Nice Prints. You won't get any clouding with FEP....I have been using FEP on my printers for about 4 years . Works very well for Big pieces too. Some resins work better then others on FEP. What you have to watch out for is getting scratches on the FEP. That happens when a Part beaks off in printing....
