The next generation of TAZ printers
Hmm, I am not sure if fixing the no material option is the best solution.
T8316 is Change Order Request for this change
@robert the change has been completed. The ohai-kits and boms have been updated. You should start seeing them in production very soon.
Thank you for this Info we will verify for the bloom this last delivery of PP-IS0086 was a lot better on the inserts except 25 of them but we took the bloom off.Thank you West for the info on the longer screws.
The photos above show that the bloom was still present. I have talked to inserts and they will pay more attention to removing this. As a back up, Lupe's people will need to verify that there is no bloom when thy assemble the chassis. @guadalupe please show your assemblers the photos in this ticket, so that they will know what to look for. That way we will not assemble the control box and then have to dis-assemble the control box again during calibration. With both of our teams paying better attention, this should not be an issue.
@guadalupe the longer screw grounds the touchscreen can
We have seen one control box with this Bright Spot issue and have come to Learn that when their is a plastic bloom on PP-IS0086 Touch screen with inserts it will cause this spot so we are also taking off the excess plastic when we put the
HD-BT0234 screw to hold the PC-BD108. Maybe a shorter screw HD-BT0104 which is an M3x8 will prevent this cause HD-BT0234 is M3x10 is a little bit longer.
PP-IS0086 thats the inserted part number.
What part number is this?

I will review this issue with Zach and MER in the morning.
Yes, we write it down but I don't think we've seen the issue in a little while. That doesn't mean it won't happen again.
@paulette Have you been putting these issues on your sheet? Looking back through the logs I don't see this issue being brought up.
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.
I cannot think of a way to test the function of this in the assembly with the current/release method of flashing FW.
Implementing a test that tests something the customer will more than likely never use is of no value to us. I don't want to add in the entire process of flashing through command line just to test this function.
The flanged hex head fasteners worked well here.
A few small printed part changes would make it perfect:
- recess for screw washer needs to be wider since the flange of the bolt is wider than a washer
- the top rear fastener needs more clearance for the wrench
Since there is currently a change order in place for this issue, I will close this ticket down.
I can also fill out a change order if i need to
@cmerot As this seems to be something that will occur on all machines under certain conditions that just happened to be noticed on the floor just now, I was asked to have you weigh in with your thoughts on how we should proceed with this.
This seems to take excessive force to rack it enough to have it happen. It took me a while to replicate, I have to strain a little to make it happen, and I can't do it reliably. There was a theory that it was due to the tab on the Z upper deflecting, but I have taken some videos and that appears to happen regardless of if the click happens or not. This click is a sound I have heard before occasionally in prototypes, and I also just tested another production unit we have over here, and I was able to get the clicking even prior to reaching Z-max.
While @zachah was able to fix some this way, I have one right now that was adjusted this way and E2 still misses the top of the calibration cube, so there might be another underlying issue.
See also T3746 for a related documentation/tutorial request.
I was able to fix similar issues to this a few times on red tagged tool-heads last week by adjusting the physical position of the nozzles on the tool-head.

Dually noted, we could add a cheap wrench to the tool kit. Hopefully they shouldn't need to loosen the fasteners that ensure their frame is square.
@tutley It may already be impossible for the customer to have to adjust the z lower screws based on what we are seeing on the floor. They are wearing through the ball jointed drivers extremely fast trying to properly assemble this part and damaging the motor in the process.
Just a cautionary note:
since we dont supply a tool for this in the tool bag, customers will have to find their own wrench to work on their machine if they need to get to these screws
We have recurring issues on the production floor regarding stripping these fasteners as well as the damage caused by the driver against the motor.
We're going to try out some hex head fasteners with a ratchet end combination wrench to tighten them.
I have requested these:
The flanges will make the washers unnecessary.
I have ordered one of these wrenches to try these out with:
James is going to bring it shortly.
hmm.. can you maybe get it sent with the inventory guys next time they head to rockies? i would like to look at it.
Got another today. Red tagged and set aside for transport back to Rockies.
yes, and when you rack it the other way where the right side is higher, it will do it's little jig and level itself. The left side makes a seriously loud cracking noise, not normal at all. It also will not lower itself off the switch after it is done, like it will when completing auto-level normally.
@DaniAO Just want to bug you again cause it still happens everyday.
oh well it is supposed to do that to level itself. It will skip steps on one motor until it is level, and both switches get triggered
Possibly, but we could not see anything getting in the way. It only does it when the x-axis is out of level and the left is higher than the right. In all other cases it homes and triggers properly.
so it is not actually triggering when homing, there is something interfering and preventing the machine from reaching zmax
Mine is a beta...
This is @tutley 's machine, the harness lays flat against the extrusion. You could try and pull the slack out of the harness
Yep, it was in. Issue is cable has lots of slop in it to inadvertently move around and end up with rubbing...
@Hob it looks like your harness isnt in the top cable clip
@anolen: Can you close this as resolved then?
Yes, I made sure to reset to default settings afer each flash, just in case.
The new .135 FW is working really well for me without an issue.
@tutley Units will be shipping with 184.108.40.206 FW as soon as we can release Cura 3.6.11 as stable. (hopefully today)
it should be
