Re: Temperature drop from 208 to 195

I am now conducting some printbed material research. I have made a printbed design and lasercutted it this afternoon.

2 different translucent acrylic ones, a white one (PetG) and a red acrylic one.

Trying the first one now I think the mirror loses it's heat quicker so I wonder what happend to the acrylic printbed, the heatbed seems to heat up quicker with the acrylic one.

All are 3mm thick, I will monitor warping, heat dissipation and other qualities, while printing with ABS.

I have made them the same size as the heatbed, the mirror I was using before, was slightly smaller so I missed out on some all-around printing area of around 15mm's.
Also the Y-endstop is very badly designed, it is keeping me from making use of the entire printbed so that will be one of the first things now I am going to re-do.

I will ask my friends is they have this thermocouple to see if I can somehow calibrate this thermistor. Otherwise, are there thermistors for sale that are already known for their properties of measuring above 150º celsius?

Thanks for your very complete reply!

Update 1:
Printing on Acrylic is a total disaster, the ABS adheres to it like there is no tomorrow.
