We could use something that says whats passable as far as the looks and quality of the vernier print. Are infill imperfections ok? Text imperfections? X and Y offset line imperfections ok? Sometimes there are lines that have parts missing from them. Sometimes the letters of the text might smudge together. Etc

T1: Test task
With the v8 gcode, once I got both of my z-offsets to be the same, I started to notice that the E1 was printing very squished once the actual objects was being printed.
I know you have been focused on helping QC stay a float, so I would like to ask @kent to look at this and fix this. We need to get this figured out asap.
Standard PolyLite profile 31 min 11 s
whatever profile was used for vernier_quick_5-15-19.gcode 18 m 19 s
I like the skirt, first layer, and second layer speed bump but I think it's a little too fast on the cylinder though. I like the way the seam is handled in the default profile better than the new one. It didn't have that characteristic blob, but it didn't form the vernier lines very well. We want something that will print a bigger skirt with only one pass for z-offset adjustment to be on the same gcode as the vernier print so the techs can dial in the z-offset manually during the skirts.
I think we could make this look a little prettier with some linear advance, it's definitely building up at the direction changes on the second layer infill and tips of the vernier lines.
There will need to be some quick edits. Just realized it is printing top layers for E0 before printing E1 on the tower, which explains why the seam looks different/caused the droop for others
@EricNugent I like the skirts. I think it would help to put a pause command in there so you could inspect the skirt and make adjustments then resume. The new edge in the model doesn't prevent the blob and does this high-ish frequency infill on the first layer that is kind of slow. The tower is too fast and melty. It took 26m 16s to print for me.
He hasn't pushed the stl of the model he's working on or the cura profile that I know of so I'm limited to editing the gcode. I can do that easily for the bed temp thing at the end, but not so much for the speed settings.
I did print this over here, but I don't have a camera to take a picture with. I didn't watch if it happened on the second one, but on the first gcode it seemed to do a "boop for good luck" after the print finished.
Looking at these photos, it appears the lower +/- seems to be connected on all the prints but it is not connected on the right hand side. Something we want to look into? (I didn't notice at first glance, so a customer might not. But seeing all these photos side by side, it looks to be gcode)
The gcode @kent made is fast and has no bloops or goobers or ooz or whatever you wish to call it.
It even does a short pause to inspect the skirts and make adjustments. I like this one the best so far. @youngmrcarlson @karrad @DaniAO @TyTh @anolen have any of you had a chance to print this out yet? This one looks like a winner.
I think the backlash setting could be dialed in a little better on that machine. gaps between the lines is a good indicator of that. What were they set to for that print?
I'm planning on intentionally setting some things wrong and then doing prints to get a good set of photos of what different offset and lash settings look like when they are wrong.
If you could post print times too that would be helpful. Getting calipers on the post for min/max measurements is a bonus. Use new polylite pla black and lulzbot green if possible to match production.
@Steven I made a calibration-print branch with the source for this calibration print, which is going to help speed up production based on my testing. I think it's in a state that it can be merged in now and included on the next tag, but continuing work will need to be done on upadating the ohai to include images of limit samples for workmanship standards.
Yeah nominal on that third one is zero... Might be best at this point to set it back to factory defaults by looking up your machine here: http://devel.alephobjects.com/ao/manufacturing/documents/master_build_log_TAZ_PRO.ods
@marcio Maybe we should set a threshold that above a certain value it throws a error message. If you have an as-measured z nozzle offset value greater than 2mm something is definitely not working in the autocal process like it's pushing through the cube or something. @youngmrcarlson did you notice any deflection of the bed plate during the auto calibration?
Some of the calibrators are having trouble measuring the skirts and setting the nozzle heights because the E1 skirt gets covered up by the E2 purge skirt and measuring the E2 skirt may not get the E1 nozzle height right. Besides that it seems to be going well.
