"Rippling" and uneven top layer Finish / on XY calibration print

So we pin pointed some issues that are obviously causing the shift in dimensional accuracy and hopefully the problems shown above in the test print.

Pulled out my Heater bulbs and one looked like this

which I thought that “browning” was bad…until I pulled out the other


So Formlabs has shipped me another set and a new IR Heat sensor.

The printer was printing beautiful and dimensional accurate with the custom Nylon 12 GF PreForm Beta they made me but obviously when they released the new Fuse 1 firmware update…something didn’t go well with those two together I assume.

As reported before my first job the chamber build plate cooked “red” and is no longer black and I am assuming it did something to the temps spiking them internal.

Or…it could have been my IR sensor went bad…spiking my temps and cooking everything.

We will see when these new parts get here if I can get it back to normal, fingers crossed.
