Did you add some brass bolts for it to rub off on?

No I did not, I guess I should try that!

Not worth the trouble. I tried all sorts of polishing media and couldn't get a good result in a reasonable amount of time (ran prints in it for up to 1 week). The best thing I've used is various grades of steel wool and my Dremel.

Thats my experience as well so far - even with sand and rocks. Looks like resin it self is a good helping agent in polishing other materials - but resin it self are almost immune to it...

I don't want to hear anyone complaining about how brittle the green resin is if you're all putting your finished prints in a rock tumbler ?

well glass is usually put in rock tumbler for polishing... its not exactly indication of "brittleness".

How many takes before you got that just right?

Dane Bennett ?

Have you opened it up to check the connection between the board and screen? It looks like it might be time to replace it

Alex Hendry I've only had it for a week and done maybe a dozen prints, do they normally go out that quickly?

Matt Kovach No they don't, but if there was a surge well it was on it could have messed it up. I assume you've already tried unplugging and plugging the machine back in? Next I'd try opening it up and checking the connection

Correct I have. I'll try that next. Thank you for the quick response

Matt Kovach No problem. People on here have been helpful to me. So jus trying to pay it forward. Hopefully you get the screen working!

Matt Kovach Oh and as a last ditch effort you can try updating the firmware on the machine

Alex Hendry I read that online before making the post, sadly it didnt help ?

Matt Kovach Damn, well hopefully the connection just needs a good push in or reset

Just to make sure... Have you tried powering it off, unplugging it from the power supply for a few minutes, plugging it back in, and turning it back on?

Sean O'Hayer that and updating firmware was the first thing I tried

Matt Kovach ok. Sorry, I would have felt horrible if I didn't ask. It's the tech in me.

My next step would be to check the LCD, as Alex recommended.

Also, which firmware did you try?

Bad contact on LCD flat cable for sure.

Is it hollow? Could some resin be trapped inside?

I don't think the volume calculations take into account any support material? are you weighing it after support material removal?

the supports are very minimal, and Im weighing the raft and adding a little extra for the rest of the supports. And I calculated it with support material in both chitu and prusa...

No, very thin parts, only about 3-4mm thick

Probably inside the print. Like parts between hollowed areas. Sometimes when you Hollow the print, it seals off another part of the print that is also Hollow, but fills with resin because there are no holes for resin to escape from these sections. Check for that. It happens a lot on prints I've hollowed.

Nothing is hollow, the parts themselves are quite small, only 3-4mm thick.

How about the resin that sticks to the model and gets washed off afterwards? It is known the software estimates are showing less then used in real

You’re using resin on places the software doesn’t take in account

Resin is stuck to the print, that is washed off, that can be quite substantial... so there is "loss" there.
Then there is resin that "sticks" to the buildplate, when your print is done, you will most certainly see some resin dripping off... leave it fo r long enough to regain most of it.
And then there is the resin that goes "on top of" the buildplate, since the build plate goes into the resin, there will always be some resin left on the non-print side....

Resin sticks to the model and the plate as it prints. That's what you have to clean off before final cure. Not a huge mystery.

Ahh, i think i have tricked myself by trying to be clever. I usually leave the prints waiting for an hour or so before cleaning to let the resin drip off. That would explain why there's resin left over but the print failed.

Thanks

I do that myself. I think the longest I've let them 'drip dry' was 2 weeks. lol

Hope you get things squared away!

add more resin mid print, just be careful not to create bubbles. and careful not to shake the printer during opening, is difficult to gently open the door sometimes

So you end up with a thin wafer that’s a shadow of the model? Or a half printed model that falls off the plate?

Neither. The first layer wont stick the plate

I've level the plate, set z. This is my first print other then the set up print

I use prusa for auto orientation and supports

Prusa?

Not sticking to the platform:usually has 1 of 2 (or both) issues:
(however there is a third)

1) Z=0 not set tight enough
(from "home" go down until it is really tight! and then go up 0.3mm)

2) Base layer exposure not high enough
(try up base layer exposure with 10 seconds)

3) your build platform is greasy due to your skin touching contact surface.
(clean build plate contact surface (with alcohol) and let it dry, make sure no residue is left)

Aight. I'll try those out

dial up the base exposure by 10 till the bases stick

Still adjusting the base exposure but is the rest ok? Using chitubox splicer

Increase the bottom layer count

Relevel? What kind of resin and what does your supported STL look like?

What all have you tried so far?

Have you changed the FEP lately? It might be not tight enough

When I level I get the paper so that it can't be barely moved. Is that too far perhaps?

Robert Clauff I used a video that really helped, which said, you should be able to pull it out with a bit of force, but if you try to push it back it bends. So yours sounds a tiny bit too tight.

Robin MacNeil I'll give it another run at #5 and hopefully I get something.

Robert Clauff Check your resin against this chart to help find the best exposure too: https://www.google.ca/url?sa=t&source=web&rct=j......

keep upping your bottom exposure. Mine were sticking until i went to something like 130 or 150

UPDATE: So here are some videos of the fail, cleanup, and re-level. I will post the settings shortly.

UPDATE: Got my problem fixed and a successful print!

Meh, the screws can be (very) stuck. As long as you don't strip them you are fine.

Bottle cap method works great. Don't worry to much about tuning it just tighten the bolts one spin at a time alternating screws kind of like putting on a tire if that helps

And done.
Used the bottle cap and the Spectrum app. Got a nice high ping. Now running the first test print.
