Random flat "plates/layers" forming mid-print
Hi everyone, I'm facing a weird issue with my Anycubic Photon Mono 4 and I could really use some help.
The Problem: Randomly in the middle of a print, instead of printing normally, it creates these flat, cured plates/pancakes of resin inside the support structure, and then it continues printing perfectly fine afterwards.
In the attached picture, this was a batch of 6 miniatures. The other 5 printed flawlessly, and this specific one also finished, but I only noticed this huge solid chunk of resin hidden inside the support structure after cleaning it up.
My Setup & Settings:
Printer: Anycubic Photon Mono 4
Resin: Anycubic ABS-Like Pro 3 (Shaken for 1 minute, rested for 10 minutes to avoid bubbles).
Temperature: Ambient is 27°C (80°F), but I am also using the Anycubic Air Pure & Heat inside the enclosure to keep it stable and warm.
Slicer/Profile: Since the Photon Workshop software doesn't have a built-in profile for the ABS-Like Pro 3 yet, I am currently using my old settings for the ABS-Like Pro 2.
Could the Pro 2 settings be causing this (maybe exposure time or lift speed)? Or is this a corrupted sliced file / USB stick issue?
Any advice on exposure times for the Pro 3 or what else to check would be highly appreciated! Thanks!
