[QUOTE="zero_zero, post: 306794, member: 9932"] Phrozen Shuffle, 4 months update... (I'm quite pleased overall) we've been running this printer for the last four months, three shifts a day (one being overnight),no leveling nor cleaning, just resin top ups... Had very few misprints, mostly due to operator errors Bird I think, I've only cleaned the vat once when someone left the cover open and the ambient light gelled up the leftover resin inside. The print quality ( C&B models mostly ) and accuracy was exceptional for a cheapo unit like this. A few weeks ago I've noticed the LCD is failing, as small (1-3 mm) random voids started to appear in the prints, accuracy did not suffer. I ordered some [url=https://www.phrozen3dp.com/products/shuffle-lcd-flat-price]replacement screens[/url] and a newer [url=https://www.phrozen3dp.com/products/paraled20]light engine[/url] which suppose to reduce curing time by 10% and improve printing quality. Ironically the day the shipment arrived the printer went dead right after finishing a print. I bought a new printer right away to avoid downtime as much as possible, then spent a few nights troubleshooting and upgrading the dead one. Luckily the Phrozen is open, based on a [url=https://en.wikipedia.org/wiki/Raspberry_Pi]Raspberry Pi[/url] running [url=https://www.nanodlp.com/]NanoDLP[/url] and a custom RAMPS board. A new Rapberry Pi and a few micro SD cards later...it turned out it was only a software issue, preventing it from booting properly Banghead Here's a few pics of the repair process, Pi board giving all sorts of errors: [ATTACH type="full"]33361[/ATTACH] You need loops to read it [ATTACH type="full"]33360[/ATTACH] Everything in pieces, new light engine installed...old one in the back [ATTACH type="full"]33363[/ATTACH] Re-flashing the LCD driver to new screen specs [ATTACH type="full"]33362[/ATTACH] We should be good for the next eight months now...Beer [ATTACH type="full"]33359[/ATTACH] [/QUOTE]
