of course! @karrad
@karrad are we good to resolve this ticket?
Sep 10 2019
@karrad so far it looks great. We didn't find any broken parts, and it's printing without any faults.
@karrad I completed the full assembly and calibration of the Mini 2 with all IC3D printed parts. @MikeR performed the drop test and is in the process of writing the report, which will be posted here once it's completed. I will print a couple prints after the drop to see if there are any changes to the functionality of the machine and any changes to the print quality. Those pictures will be posted here once they are complete.

As off now, we no longer have assemblies that are non-conforming. We replaced all of the Y-Corners that are causing this issue. It doesn't seem like there is a large number of these parts as they were reaming parts they shouldn't have. That will decrease the fallout of this part. However, I do agree with @tutley that we should reintroduce the set screw.

Eric H. and I went through and trained the technicians on how to properly install the M3 washer. We received some good feedback, and will go over the OHAI to match the assembly process they are more comfortable with. @MichaelM if you have any more feedback, please let us know. Thanks!
All torque wrenches were calibrated and logged.

I'm assuming you currently have orders for the store? If so, we'll get someone over there as soon as possible..
@MichaelM Let us know if any one on the team needs any training on how to properly install the washer.
@MichaelM Updated.. How does it look?

^ The first is the intial calibration print from Cal, which flagged this toolhead. The 2nd (with the 4 calibration attempts) is the "different speeds" gcode. The last photo is the calibration print from the "vernier1_green" gcode. FYI
@karrad I'm going to need IC3D parts for a Mini 2. As soon as I get those, i'll be able to assemble the machine for a drop test
Aug 6 2019
@karrad I completed the IC3D ABS strength tests. (Thank you so much for your patience!)

OHAI has been updated with the new calibration print. The Z-Square step has been deleted. Closing as resolved.

@kent sounds good. If we can limit the defects to the rear, it would make it even easier to pass that specific defect
@kent Is this something you feel we should proceed with? It would make this part have over a 90% pass rate. I feel it would make it much easier on production and remove all the guessing, which would greatly increase their output. Or do you feel we should create a spec (without getting too picky) for the supplier to work with? Either way is okay with me
@AOJAS I respectfully disagree, unless we make changes to our Workmanship Standard Document. The goal is to be consistent. Some of the plates you did not red line do not have a quantifiable difference to them. We are going to red tag all of them until the supplier ships better quality plates or we can quantify the defects on this specific part.
Pre-Sub inspected 50 of the Z-Upper Plates and rejected 23/50. The issue that I'm seeing, is that the defect that is normally to the rear of the plate, which I believe is a "C" face, is now in the front ("A" face) for the majority of them. I have a picture attached of the front of some of the plates we rejected

Blades have been replaced
I'll run over and replace the blades. I have a couple of things I need to get/take over.

@anolen Can you take a look at the profile and see if we can correct this issue? A reseller (RMA13250) has had some difficulty with this print @Steven requested that we take a look at the profile and see if we can resolve this ticket.
@DaniAO I'm using the standard Polylite PLA profile, except I'm on 3.6.8. So, I'm going to update immediately.
I also printed this STL on a TAZ Pro directly off of the line this morning. It's now 4 TAZ Pros (Including the customers returned machine) that is showing this issue

Completed all requested OHAI content. Please reopen if we need any other instructions for assemblies.

I was told that there are two mechanical assembles that don't have assembly instructions for them (AS-PR0124 and AS-PR0143). I will get that completed pronto
May 13 2019
The Thermal Insert Instructions have been updated with links to the mechanical assemblies that Pre-Sub produces, along with links to other assemblies that use those parts. I made clear on what assemblies the links go to, in order to reduce confusion on where those assemblies are produced. @david.hall let me know if there is anything you would like me to add or change.
May 9 2019
OHAI instructions have been created for the Y-Motor, Y-Idler and Extruder Cap sub-assemblies. I believe that covers all of the missing mechanical instructions for sub-assemblies. If we are missing any others, I'd be more than willing to complete OHAI content for them.
May 7 2019
@DaniAO The OHAI has been updated. As I understand, there will be a meeting to finalize the QA process for Quiver. Please update me if there are any changes in the process for the AS-PR0144 sub-assembly. Thanks!

Improved by increasing text size, aligned text and evened out pin assignments to make it easier to read. Files attached.
Apr 11 2019
In this case, the changes that are needed are applied to branch T6486 for review.
Removed step 20. Closing.
Apr 9 2019
@paulette On the QA sheet, we do have "The level-during-home feature works as intended and the x-axis is level." So what you noticed is redundant. I have the blessing from @kent and will go ahead and delete that step.
I removed the 4mm strip length callout for EL-WR0119. All other JST wires are cut at 2.2mm. I uploaded the original and the updated version for comparison.
@kent for clarification, shouldn't we add the Z-Clamp torque procedure in step 4?
Apr 4 2019
@kent I updated the T-Slot position drawings for the front and back of the frame assemblies. Ready for review.
Apr 3 2019
@kent I added the recommended tips and temperatures for this OHAI. Let me know if there is anything I should change

@MichaelM I verified and made the changes to part numbers you mentioned. Also, on step 3, it says "The zero volt sense harness needs to be attached with the external star washer, the zero volt sense harness and the M3x8 BHCS screw in this order." Would you prefer we change "external star washer" to "External Lock Washer" including the part numbers for those parts to be more clear?

We received a RMA that had the Rambo fail because of the amount of dust and debris in the chassis. I took some pictures of the board and power supply after a good portion of an air can was used.

I agree. I replaced the flat head screws on the top because of the fear of them stripping out in the future. I believe the M3 socket head screws would be a more reliable alternative for removing and replacing the tool head cap.
Nov 8 2018
Sounds goods man! Let me know if any part of the process changes so at that point we can update the OHAI. Closing.
Nov 5 2018
@MichaelM, I made some changes to the OHAI. Let me know if there's anything I should add or change according to the current process. Thanks man!

@kent I added some photos for steps 13 and 14 with some slight editing. Mind reviewing them?
May 25 2018
- X-Axis wouldn't level due to Z-Axis compression bushings being tight (Corrected)
- Makes sure to verify all torque values using Step 4 in the Mini 2 Calibration workflow. Had a few screws (Z-belt clamps, bed leveling washers and the wiper pad holder) that weren't torqued enough. (Corrected)
- Right Z-belt and the Y-Belt were slightly loose (Corrected)
- X-Belt rubbing the side of the Idler (Sent back to production to be reworked)
May 19 2018
- Bubbles in PEI (corrected)
- Left/Right Z-Belts tensioned more than 5N apart, 38N/48N respectively. (FWIW, I couldn't find this anywhere in the OHAI) (Corrected)
May 18 2018
- Y-Belt tensioned to 48N (Should be between 23N-27N)
- Extruder cap not seated properly
- Left Z-Belt tensioned to 28N (Should be between (35-45N)
- Extruder mount should be torqued to 5 in*ibs
- Z-Belt clamps should be torqued at 3 in*lbs
KT-PR0047NA-13635: Inconsistent print quality (On hold)
May 14 2018
- Left Z-Belt tensioned to 60N
- Scratches on the control box
- Extruder harness connector pinched under Extruder Cap
- Connector pinched under extruder cap
One from today
Calibrators: Prior to sending the initial release machines packing (yay!) do a quick once-over, specifically for scratches on the sheet metal. Over the weekend I found a few machines that had scratches either on the control box, bottom plate or left plate
