RE: Hope I'm doing something wrong.

That has to bite.  Hopefully they can send you a new screw and the screen will be ok.  

Good luck!

RE: Hope I'm doing something wrong.

if the screen is backlit, you should be able to take a flashlight to it and read it.

RE: Hope I'm doing something wrong.

Ok home from work, i'll give it a try

RE: Hope I'm doing something wrong.

I saw a SL1 manual floating around online and took a look at it.  It says that you should use your camera on your phone to look for the logo because the light is UV.  It makes sense; depending on the light source there may not be much to see but it can harm your eyes to look directly at it.   Digital cameras like the one on phones do pick up UV, so that is why they were asking about smart phone pictures.  

Good luck!

RE: Hope I'm doing something wrong.

Ok update.
Tech support had me reflash the firmware. Still cant see logo on the uv screen with my eyes, with my phone I cant see logo on uv screen.

I was told to look under the sl1  for uv bleed. I never looked under the unit. In fact my phone does pickup up a blue light under SL1.

RE: Hope I'm doing something wrong.

The orange plastic blocks UV; you should not see any through it.  Non-UV light would still pass through I guess.

I take it page 15 is what you are looking at as far as instructions.  It does depict looking through the orange plastic, so that is not the issue.  If your camera is picking up UV from under the unit, then the UV backlight is working.    That pretty much leaves the possabilities of something being wrong with the mount for the backlight assembly (I think this is unlikely, but could be possible depending on how the internals are arranged) or the screen.  Your pictures look like the LCD is totally black.That could be a bad screen or a loose connection to the screen.  Given Prusa's QC I would assume it is most likely a wire that became loose in transit.  Have you tried to shine a flashlight on the screen?  If the screen is working you should be able to see through it with a flashlight; if it is totally masked/darkened you will see nothing but your reflection.

RE: Hope I'm doing something wrong.

Yup I tried the flashlight b4 posting this, no luck. I think its a probably a loose connector also, but idk.

Quality Control:

no factory check list shipped

1 of the thumb screws has a larger diameter then the other one and does't fully thread (so i cant properly secure tank to uv screen)

uv screen doesn't work. could be it never worked (no check list, idk). If it came loose in transit, it was't secured properly. So either not a connector with a clamp or no hot glue, idk. 

Waiting for tech my rep to respond to pic.

RE: Hope I'm doing something wrong.

No clamp.  The screen uses a ribbon cable.  This is almost certainly your problem here.

The assembly for the UV LED's is not likely to become detached or something.

Edit:  The timestamp videos don't seem to be working embedded in this forum for some reason.  The first video is at 2:00 and the second is at 2:53

RE: Hope I'm doing something wrong.

Ok after exhausting all simple troubleshooting Prusa wants the SL1 back for evaluation. Will ship a new unit in the mean time but didn't say when new SL1 will ship.

Still a fanboy but after waiting since 9/22/18 getting a unit with quality control issues sucks. 

RE: Hope I'm doing something wrong.

I hear ya.  It is frustrating to wait so long to get a dud.  My head would probably explode.  >.<

About when yours was shipped I was told that 5 units were just shipped.  That surprised me that they only shipped 5.  It makes me wonder if they were still working out the QC measures.  While that might explain why there was no QC checklist, but not having a matching set of screws is weird.  Since they redesigned the screen assembly from beta feedback maybe they had to change screws and one of the old screws made its way into the batch of new screws? 

May your new unit come soon and in working order!  🙂

RE: Hope I'm doing something wrong.

Replacement shipped. Should arrive tomorrow or Friday the lastest. I'm still a Fanboy

RE: Hope I'm doing something wrong.

It shipped already?  Nice. 🙂

RE: Hope I'm doing something wrong.

Landed. I can see the prusa logo and thumb screw actually fit 🙂

RE: Hope I'm doing something wrong.

Now to have some fun with it. >:)
