@anolen made some edits to the initial alginate profile, which resulted in the profile attached here. During the print using that profile, she also noted the following possible improvements that has not yet been implemented or tested:
Reduce wall & infill overlap
Reduce speed by 1mm/s
turn travel-combing off

Confirmed single nozzle extruder to right washer center at x293 y-14. Thats 3 production dual extruders and 1 single extruder confirmed on this machine.

@karrad I did verify my Y axis location.

For the record, that machine was one I got from Steven, who told me it was a production unit. I have not made any modifications to it aside from a blower shroud replacement for testing.

Change order ticket is T7856

I think we just need to remove it from the BOM. I can get a change order submitted a little later.

Material printing has same off-gassing concerns as ABS.

@karrad I tested just now by setting to toolhead 2, connecting to the machine, switching to prepare, and then switching back to monitor. The issue was still present. Firmware 2.0.0.116, Cura 3.6.9.

@MikeR from Kent, when discussing design review of machined fixtures prior to fabricating them "For now, the plan is to leave the process as is, and revisit this issue with our new Manufacturing Engineer."

The call with TVF for material safety and ventilation will be at 10am next Wednesday, 6/5/19.

regarding ventilation for the furnace - "Venting is encouraged for inside use-- Here in the foundry we have what is essentially equivalent to a bathroom fan for venting purposes. If you are using the unit in a well ventilated area a ventilation system will not be required."

Here is a spreadsheet of necessary items and costing based around Virtual Foundry filament and the furnaces they offer. Note that there are two pages based around 2 different furnace sizes which influences how large of a part we could process.

I have received confirmation from BASF that they see various options for sintering environments, but the catalytic debind has no alternatives for their materials. They did say however that they intend to sell the filament with a deal from their own sintering vendors which you would just mail the printed parts into, instead of expecting people to invest in the equipment and testing.

Upon my arrival to the show, which was after the unboxing, setup, and some initial adjustments I proceeded to do the following to get it working:

MTIXTL responded that they no longer offer that furnace. I am discussing other options they have.

RFQ sent for https://www.mtixtl.com/GSL-2000X-HV.aspx

I have gone through the final production BOM and found items that were not included in the previous BOMs I was working off of. This is the new list of items we need RoHS documentation for:

Solar has responded with $275,000.00 as the price for their furnace.

@DaniAO Yes

The Virtual Foundry has responded with pricing for their various chamber size options.

RFQs sent to Virtual Foundry, solarmfg, and another I found at https://vacuum-furnaces.com/laboratory-furnaces-series-50

According to the BASF Ultrafuse 316LX datasheet I am looking at, sintering can be done in pure hydrogen or vacuum, so we can probably do that with the same furnace in vacuum. The vacuum furnaces that I am seeing are also listed as able to do inert gases. For hydrogen, such a furnace would require additional safeties. I think we should stick with vacuum unless we have need to test gases, just for the sake of not dealing with the gases, but we would have that ability. The BASF material does use a special debind process that also raises concerns due to airborne acids, but in theory could also be done in the same type of furnace. Virtual Foundry materials seem to do a thermal debind that is just contained in part of their sintering cycle, which simplifies things a lot.

I would like to start sharing files with suppliers and it would be beneficial to be able to use devel links. Is this something we can get some movement on at this time, or should I use alternative methods of sending files for the time being?

We did recently switch to a new supplier for the LCDs, so we should probably start with determining if these were from the new or old supplier. Do we have serial numbers for these machines in order to determine that?

@west is working on this presently

I believe that was LTAZPROSL02M_3DBenchy

@kent do you have any data from production as to what a good pass/fail point is, to use in setting the tolerance?

@kent
From the guidelines for drawings:

It has also been discovered on this drawing that on page 2, there is a callout for the flange width at "140.0 X2" that was left over from before the flange change, and needs to be corrected to the new size.

documentation received for PP-FP0087, the purchased material used for AS-PR0023

documentation received for PP-FP0087, the purchased material used for AS-PR0023

Data shows that these tend to have been on the low-end to a little out of the spec in that direction, which is likely how they have been working so far.

@west I believe we are good

EL-MS0531 documentation received

While the actuators were extensively tested, and the one wire we saw issues with from the movement of the actuators was replaced with one more robust, the moving wires on the toolhead introduce more fatigue and the actuator is an additional potential failure point that previous machines have not seen in that area, so the toolheads could see an increase in issues compared to other aero toolheads.

HD-MS0311 documentation received and added to the pile

@jperry can you clarify which part numbers are for which document?

We can now check off the following:
HD-EX0092
HD-EX0090

HD-MS0310 received and logged

Documentation received and logged for DC-LB0153

Documentation received and logged for:
HD-MS0471
HD-TB0007
EL-MS0536 (this is the actual part number for the actuonix actuator)

Documentation received and logged for DC-LB0094

chassis cover either needs some center lines connecting the rightmost and leftmost holes, or some 2Xs on the dimensions.

EL-MS0434 (red heat shrink tubing) now has documentation logged

EL-MS0434 (red heat shrink tubing) now has documentation logged

@kim I think that part is now the EL-MS0530. I did not realize it had changed part numbers. Everything listed here should be on the quiver and/or hibiscus BoMs.

Here is the list, which includes a few items for the mini 2 as well, which was most recently sent to purchasing on 1/8, from which I have removed the couple of items that we have received documentation for since then.

Electronics chassis:
weld and grind for edges never called out, suggest adding to page 2
PEM inserts for LCD mounting never called out, suggest adding to page 3
Page 1 Note 2 requires some sort of tolerance. Suggest profile tolerance similar to quiver electronic chassis drawing.
Page 3 missing hole size for knob cutout
Page 3 use of centerlines over the slot pattern looks weird. Suggest using full leader lines taken from furthest in slot.
Pages 4 and 5 were printed out and redlined
Page 6 looked good

@west it should be fine in this case, since we are making the model match the drawing, and only the drawing is referenced as being a specific revision.
