Little RP- new, not yet calibrated. Weird issue- did I break my projector?
Posted: Mon Sep 11, 2017 1:29 am
Hi all! I am new here, and slightly overwhelmed, so please forgive me if I missed something in my searches..
1. The main issue. After printing for about 6 hours, I now have a band that goes across my print area, where if I print out a full print, it is shrunken in height at that area. I started a print and cancelled it after two layers- the build plate had a visible band there where resin did not cure... Did I melt something, or melt part of my projector? - Attachement showing a full print with a shrunken bit. Both sides should be identical and flat. The undercured? band makes it curved. (I did not replace my Teflon in the vat yet. Could that be related?) - Photo attached of a result. It's blurry, but it is the best photo I have that shows the issue, quite clearly. Sorry for the low quality- it's close to midnight and I am being lazy
2. I assume it is because my calibration is not dialed in, but I tried printing a similar object angled with supports, and the supports did not generate, and the object was missing a large chunk. A different time trying this, JUST the supports printed. (Not a slicing error) - any link to a good guide on calibration that worked for you would be great..
3. I have Makerjuice SF because it was cheap. Unfortunately, even though I cured the objects outside (at full sun at 5000 feet- so plenty of UV) for multiple hours, and cured in a UV nail curing bax for an addition 15 minutes, it did NOT play nice with platinum cured silicone. (I used mold release and everything) - what is the best resin for the little RP2 that also plays nice with silicone curing?
Specs of setup:
Little RP 2 extended height, normal vat size. Acer x152h, shimmed. Makerjuice SF red
Thank you for your help!
