This seems to be a design issue for many. I had the same problem. The sensor can easily come loose and get between the building plaform and the resin tank film… I check the resin sensor before activating the printer but it can become loose while the building platform is coming down.
Even if the film of the resin thank is not fully perforated, so does not leak resin onto the LCD, resin will eventually seep into it and cause delamination when the resin will “grab” the film and mess up the print. This has happened to me recently when printing a UDP model provided by UNIZ as an example. I put up a post about it earlier.
UNIZ will need to improve the design so that the resin sensor is properly retained in the meantime it is a good idea to secure the sensor as suggested by James.
Indeed ! This is one annoying issue that can cause significant damage and is at best an ongoing problem that a SLASH user always has to be aware of in order to prevent such significant damage from ocurring.
Damage can include: sensor damage, resin tank damage, LCD screen damage and potentially damage to the mechanism of the build platform, amongst other things.
PLEASE UNIZ you need to address the issue !
Sorry for the inconvenience caused. We had addressed this issue and improve the design of sensor support. If your resin tank was damaged due to loose sensor support, please send a email to email@example.com. We will send you a new resin tank and a new sensor support.
