Anycubic Photon Printer Owners 造訪社團 » 用戶發文

So, how do these ones work? The platform Prints every leyer at a time controlling the different exposures without moving the build plate?

Yes - just like the "old" firmware patch version, except this one is built into the running firmware! You get base + 8 seconds for each of the 8 objects. I had to hack together an STL based on the original photon files which are too large. I didn't want to scale so we could compare printer to printer.

Honestly, I haven’t found resin to be good for perfectly flat requirements. I mean, you really wouldn’t want to make anything mechanical with this stuff.

Don't print it flat on the bed. The suction twist the "bottom layers"

would not worry about it. printing directly of the bed is where the base of supports are and those are throw away. so alsong as the models stick and tbh the pics look fine.

i tend to print miniatures directly of the base as the base. again the pics look great. :)

I print a lot off the bed as well, and it's just bad enough that it triggers my OCD. :) I'm printing a better test object now - this is my first Anycubic, so my first go with the bed mount / leveling mechanism.

Man, you're asking a 400€ printer to be as accurate as a 26 000 one. Guess what ?

John Driggers I mean, I wouldn’t say it’s OCD until you’re up at 3 AM printing your 20th imperfect cube because you’re afraid your house might catch on fire if you don’t.

No, I'm asking that it be as accurate as a $299 one a single axis. The $26k one I get 0.025mm out of on three. :)

Ah, I see your problem. Your test equipment is too good! Use cheaper and less accurate verniers and the problems will go away ;)

Also, this is a good solution. There are others out there that do the same thing, and on thingiverse if you want to make your own (metal is smarter to use then resin). Set this right, and making sure the photon itself is level to start with, and it'll eliminate that discrepancy pretty well

That looks a lot like what I want - thanks David !

John Driggers Teh you're already as accurate as you can be with a photon. Now if you want something a little better, take a better resin. The machine itself can't get better than that.

David, do you know off the top of your head if the Zero and the "Normal" Photon mounting heads are the same size? I'm not at the house yet....

John Driggers not off the top of my head, no.

agreed. I recommend SPI. Or as we in the machining world like to call them Sorta precision instruments.

It's a chinese printer, use chinese gauges!

Resins have properties FYI, shrink age and elongation. Unavoidable. Some companies clearly state those properties, some dont. The printer itself is not the issue, the resins are.

Try leveling your entire machine, then level the bed. Leveling the bed really only makes it flush in regards to the build plate, but if the machine isn't level, nothing will be...liquids need to be level to the world, the build plate only needs to be level in regards tot he bed

David Collinson just an FYI - not the same, nor the same mechanism. I was able to carefully tune most of it out by repeatedly leveling and retightening. Gonna try and figure out what’s causing it and see if I can come up with a solution.

You think it's the resin that causes one half of the print to be thicker than the other?

you are fighting with exposure(over/under) and bed leveling, best way to avoid those is to put 5mm supports on it.

I had the same problem. I kept leveling and always the same issue. After the first layer it would loose its leveling. Doesn’t matter how much I tighten the top screw! I installed the easy leveler with some adjustments and the problem is solved
