the Form2 is running INSIDE a steel cabinet, inside my office space. while the temperature varies a little bit- from 68 to 77 during the course of the day, that is within the advertised operating range of the printer. The printer also has its own internal heater to maintain resin temperature. and being inside a cabinet ought to make it easier for it to maintain temperature.
While temperature was one of my first considerations, i have seen no correlation between its resin sensor error behavior and overall room temperature… its as likely to stop printing i the middle of the day when its moderately warmer, than it is in the middle of the night when its moderately cooler,
At no time is it at a temperature that is not comfortable for ME to be in the room with it.
And my position that any senor system that would require controlling the room temperature within a just a few degrees is STILL a design and engineering failure… not operator error.
if the thing can not reliably print in an office environment… then its not even up to the product standards of an inkjet printer.
so far their only answer has been to send me an instruction sheet on how to ‘tighten’ the sensor level plate screws on the bottom edge of the sensor plate.
but they were NOT loose. they were actually tighter than the level of torque the white paper recommended,
the intermittent and capricious nature of the errors leads them to believe that the sensor plate is not properly grounded.
And that would fit in with your temperature suspicion, as minor changes in temperature could be causing the ground being lost with slight expansion and contraction of metal parts.
however- others have reported that adjusting these screws had no effect… and I would point out that a bad solder joint or poorly made connector between electronic components could just as easily form a super temperature sensitive “switch” in the ground state of the sensor.
Either way… its a bad engineering design or a bad assembly.
Formlabs needs to address this as a great many users are affected.
out of 7 prints i have run since I bought the thing… I have had exactly 3 print without spurious sensor errors causing flaws in the print and major delays.
that is unacceptable for any productive tool.
