I updated the OHAI to say to use the "Automatically upgrade firmware". The version of cura-le on production workstations is 3.6.6 which uses .109 for Taz Pro. If we want .110, then we need to install a version of cura-le that has .110.

I'm just going to leave the version number off and go with "most recent". If I were to put a version on there it would just be wrong as soon as we rev'd the fw which happens all the time.

Well what's in the table doesn't match what's in your spreadsheet @oliver so I'm guessing these were taken empirically, or the spreadsheet is wrong, or the units are not what I think they are. Something's fishy.

The units are kΩ on the left and °C on the right. This is the datasheet https://www.mouser.com/datasheet/2/362/semitec%20usa%20corporation_gtthermistor-1202937.pdf but it doesn't give a table, just a B value. I'm not sure if the steinhart hart eqn would product values that match the table, or if those were taken empirically.

@logan we have a significant amount of testing (especially drop testing) that would have to be re-done if we were to change the orientation of the snap ring. Not to mention that it is designed to work one way and not really intended to work the other way. We have seen snap rings pop out during drop testing if they are installed backwards, so I do not recommend it.

kent added a comment to T6542: Glass moving on top of heater.

Here is another test gcode to check for bowing and level. I like it because it is a single bead, and it is easy to tell where each piece came from after they are removed from the bed. So far, the results are looking good.

kent added a comment to T5073: False positive reading from filament sensor.

It is possible to disable the filament runout sensor by turning the threshold all the way down. If it is reading lots of false positives for a specific material or environment, then this is an option for the user. Beware the false false positive -- where you think you have a false positive but actually there is a legit filament feed issue that can't be detected just by looking at it or it's not really showing up in the print as artifact. I think this is likely the case for large spools with lots of weight and friction.

kent added a comment to T6542: Glass moving on top of heater.

@west I tried those 2.2.2 corners and they are great for keeping the glass part of the bed from sliding around. The heater is getting compressed too though in x and y which tends to bow it down, so I made a 2.2.3 version that has a cutout where the heater sits so it has room. I was a little worried about the 2.2.2 version making it hard to get the leveling washer flat since it is 6mm tall where the bed sits now, but it works just as well as the stock Taz 6 two piece bed corners.
