With the jig that Logan has made I was able to adjust two more tool-heads that were red tagged for this reason. With one the protrusions after adjusting with the jig were E1 3.43 and E2 2.38 with the shroud sitting 0.60 lower on one side. The second 3.72 and 3.27 with only 0.06 difference between the shroud sides.

Added clarification to the OHAI on this
"Put the filament guides into their correct sides, they should only fit on their appropriate cavity. [PP-FP0136] - Mirrored filament guide is for the left side. Whereas [PP-FP0158] - Standard filament guide goes to the right side"

zachah added a comment to T9720: Tool head range of motion.

We've got an RMA that was sent in for actuators not fully descending. I'm currently running some tests with the auto-calibration to test the offset consistency of this printer. My hypothesis is that any inconsistencies with the actuator movements should show up in the calibration data. Since it's measuring the distances of the nozzles relative to each-other, if one or both of the actuators aren't consistent in lowering, the offset data should be inconsistent across calibrations.

Here's a gcode I generated with increased minimum layer time increased to 30 in order to slow down the print just a bit more on the cake part of the print. I also added two skirts that are printed slow enough to make adjustments to the Z offsets while the skirts are printing.

zachah added a comment to T7654: Under extrusion from toolhead?.

When printing a few of these I noticed that the skirts have changed. I believe we need the skirt to be further away from the vernier to have time to adjust the Z offsets while the skirts are printing and to verify the squish consistency of the bed. With the skirts so close to the vernier we can't really do that. If we add back in the skirt from the previous g-code and also slow the skirt down just a bit that would help make calibration easier as well.

zachah added a comment to T8218: E2 nozzle misses top of calibration cube during auto cal.

For the printers I have installed them on the double wide wipers did get the wipes to be within the pads whereas they were wiping on the plastic before with the single wide. Since designing the spacing jig I haven't run into any printers that don't wipe in the pad after being adjusted with the jig either. So between the jig to ensure consistent spacing across tool-heads and the wider wiper pads, these combined should be able to fully resolve this issue. Based on my observations either one gets the wiping to be within the pads consistently.

Just had a Pro act up when I flashed to .135 with a USB drive inserted. The printer was stuck in a reset loop after flashing. I powered off the printer, took out the USB drive, then it powered on fine. I thought maybe it had corrupted the USB drive somehow but after resetting the printer and re-inserting the drive it seems to work fine. This is with the older green flash drives as well.

I've got a jig that I whipped up to hopefully help provide consistency between tool-heads when it comes to wiping and calibrating. From my testing with 6 red tag tool-heads the X offsets are looking more consistent across these tool-heads. The X offsets from the 6 now range from 45.83 to 46.54, within ~1mm after being adjusted with the jig.

After some additional troubleshooting with the red tag printer showing this issue I decided to get the left side belt a bit tighter. In order to do so on this particular printer I had to take off the control box to access the bolts to lower the left side Z lower by 1mm. With both sides tightened up I can no longer reproduce the sound by racking either the left or right side.

We just had another printer on the production line crop up with this issue. This printer was doing the clicking on the left and right Z side. We were able to verify that it's not the Z upper but rather something in the X idler and motor sides as samantha theorized. If you stop/interrupt either side of the axis by hand on this machine the clicking would happen.
