@logan let us know if you push this to Cluster, so that we can identify the part on our board and make a place for reserve. Inventory will have to make a location for it also. I assume that it will be a part number change? We will have to check back stock and see when you want to roll in on the production floor. Also and updated OHAI?

david.hall updated subscribers of T9890: EL-HR0181 Y-Z End Harness, Assembled Rev c / CCX review request.

@dylan we are probably going to end up reworking all of the cables ourselves. I would like to get a time that it takes to rework the cable, plus any material that we use, so that we can charge back to CCX. Please see if you can identify that for me. I agree, no need for a zip tie or anything. I think the short re-work time on these will be no problem for us as to the benefit of having the cables done and having the stock available.
@kim or @sherylb may know the PO for the batch of EL-HR0181 that we received.

@west , that is what I thought, which is why we are going to rework all of the cables that we received from CCX. I am curious as to what stops the cable from slipping in the braided shielding? which is why I was asking whether we need a zip tie at that point or not.

david.hall updated subscribers of T9890: EL-HR0181 Y-Z End Harness, Assembled Rev c / CCX review request.

@draubach can provide a description of the cable received from CCX, but if memory serves, the black wire coming out of the EL-WR0157 braided sleeve, actually comes out of the HD-TB0075 heat shrink tubing at the top. I believe that the wire has to be free enough to be connected correctly, but if we want it behind the heat shrink tubing, then we would have to have a zip tie or something to keep it located. I think we need to see if the cables we received from CCX will work as is first, then see what we need to do.
@draubach can confirm but I believe that all of them have to be reworked for us to be able to use them. We are planning to rework all of the cables here as it is far easier to fix these harnesses than build new ones and have CCX fix the issue. We will need to determine what to do for future orders rfom CCX.

david.hall added a comment to T9863: PP-GP0360/PP-GP0359 Z-Lower Left/Right gcode for TAZ 6.

@logan , after reviewing the issue with Cluster techs, it appears that we are able to print these on Mini, but the file will not work well on Taz, constant lifting. We can either remove it from the folder or do some slice testing to see what the issue may be with the lifting. it could be due to the large print area that we are transferring too much heat and allowing lift. It may be that a temperature adjustment will take care of the issue. Perhaps we can remove it from thew folder until testing can be done?

@paulette This is what @logan just found "This should not have made it past the CB test. The test will finish with this error, but proceeds past the "Press PROBE" step without human intervention. CB Assemblers/testers have been instructed that this constitutes a failure and to be more diligent through the testing process. The unit should wait indefinitely until that probe button is pressed."

I will get with the Cluster techs and make sure that they follow through on QC. We need the people installing them also to look at the print, a squished print will have a ridge/brim on the bottom of it. That way we can have more sets of eyes on the parts and will not get a bad part installed and make it to calibration.

david.hall added a comment to T8835: Printed LulzBot Plaques.

Point 2 above: Before anyone decides that Cluster will print these in ABS, a file and a test will have to be done. The Cluster pods cannot fit a Pro in the cabinet, especially with 2 rolls of ABS filament. In addition a print this thin will likely warp and cause lifting and a very high fail rate.
Point 4 above: Pro printers do not fit in our cabinets.

Talking with a customer, he was having problem after problem with his Taz6 running Inova 1800. We swapped tool heads and thermistors and then finally went to another printer, with similar results. 2 Min temps and several thermal runaways until we changed profiles to nGen and adjusted the settings. Then the print would do fine.
Can we confirm this issue?

david.hall added a comment to T8313: Blower shroud sagging.

@EricNugent I don't believe that we did this since we have done the current reduction on the motor? "I adjusted the bed temperature and @Shawn replaced the blower shroud. The workhorse edition slices may need to have a max bed temp for printing in enclosures due to the size of the bed and enclosure conditions." T7793
It may not make a difference at all with the current reduction. I was just curious.

Jul 17 2019, 7:35 AM · Redgum
david.hall updated subscribers of T8313: Blower shroud sagging.

@karrad we have not tried lower bed temps. Printing production parts, I would be wary of "ABS lift". If you would like we could have @EricNugent do a part or two with a reduced bed temp in a "test" folder, then we could try them and see what they do. We would have to isolate the test so that we don't harvest any from there until we verify if lifting is an issue.

Jul 17 2019, 7:23 AM · Redgum
david.hall updated subscribers of T8313: Blower shroud sagging.

@Steven this is a good 10c lower than before, so that should make a difference. The biggest factor, I am sure will be that the enclosure exacerbates the glass point transition factor. I don't see this as being an issue with any customer use. We may just want to advise "Cluster" users to print fan shrouds from a higher temp material.

After reviewing all of the information with Lupe, I think we will go ahead and us the sub assembly number, so that she can build ahead (est. 50) Then when the chassis is being assembled the parts can just be installed. This appears to be the way to go presently. I will re-visit this with @cmerot to see if he would like this to stay or change. Could we please set this up so that all parts are delivered to Cables at the Rockies bldg. They will make the sub assembly. Also @Heather could you check the el-ms0235, as it says that they have 40 at the Rockies, but they currently have 4. That way we can start on the installation of these in our chassis. Thank you

@tutley , while I agree that it was a good idea for the angle, the current system is not working. You already have a tool head that extends above the top of the printer when it is at the top of the Z and customers know to be careful with a $5000.00 machine. I believe that this is a good idea that will solve the usb issue and we have too many issues in hand currently. I don't think walking by a machine can cause someone to snag a Usb that is pointed straight up on the top of a control box. I do appreciate the concern, but perhaps this is something to consider.

david.hall updated subscribers of T8585: High fallout of USB bezels.

The old version is working. They had a number of bezels that did not have all of the "skirt" removed and that appeared to be causing the problem. We have over 2000 of these and they were still approved to work. I don't want to remove over 2000 parts. We will just have to get Cables to verify that the skirt has been fully removed before they install the Bezel. Then we can ask @tomc to see if we have manufacturing requests in for producing more of the new parts. Just a note: when I went through the bag of the 55 bad ones, there were some of the new Bezels in that bag also, so we will need to keep our eye on the fallout of the new ones.
If anyone wishes to, we can scrap the old version and start producing more of the new version so that we can keep up with production, but then the old stock will have to be gone through to isolate the old from the new. I definitely will not be able to accomplish that today.
Please let me know how we want to proceed.

david.hall updated subscribers of T8313: Blower shroud sagging.

I was talking with @karrad this morning about a customer with a fan shroud droop issue. It was suggested that the motor was getting too hot. I put a thermocoupler on our printers in Cluster and found that we are having a constant temp of 190f with spikes well above 200f (93.333c). This will definitely cause motor wear issues and cause issues with transferring that heat to the fan shroud. We should be looking at a firmware update to reduce current to the motor, thereby reducing temperature. This may alleviate the problem.
Let me know what you all think.

@karrad Do you know if we have documentation on the process that we use to verify parts as we introduce slices to a new printer? That may be a good starting point for a QC parameters set up. I outlined above how we QC parts in Cluster, but having a pre established guideline may help.

david.hall updated subscribers of T8306: Redgum Chassis PP-FP0172 Masking issue.

I was just talking with @kent about taking 15 of the chassis and grinding the ground locations ourselves. This will allow us to build the 15 WE printers (our production Beta run) this week. I believe that we can use a tool that we have in Cluster to do this process. Then we can move forward with building the 15. We would need to identify who is capable of doing the grinding and get that set up so that we can get these chassis to Cable/ harness, to get the 15 built, so that we can move forward with this build process @bowman , we will need to adjust the timing of the production schedule to reflect the issues with the masking on the chassis.

@logan, You expressed what I was thinking well! I noticed when looking at the Taz6 next to the WE that the space between the fan shroud and the bed surface seems to be less on the WE. Meaning that the fan shroud is closer to the bed surface on the WE than the Taz 6. This may lead to the concept expressed that the ambient temperature is higher than on the Mini and this is contributing to the droop.
I was thinking(may be problematic) that we printed the fan shrouds on our Mini's (in Cluster) from Village Plastics ABS. We have since moved to Chromastrand ABS. Is it possible that the filament change could be an effect here? We could print some fan shrouds out of IC3D ABS and see if we have the same issue. Just a thought.

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.

We will update the ticket, just as soon as we have a couple of days on the printers testing the 425.

@Shawn please get 4 additional parts printed, so that we can remove the ones on the 4 printers that have been Loctited and then install the new parts and use the 425 Loctite that I brought you. This will give us better test results. Thanks

@EricNugent can you tell me where we are at with this? I have it on my list as a part that is not ready to print. Can you please let me know if the file is valid. If so, I am going to run a small production run.

david.hall added a comment to T7968: Y belt mount fasteners falling out in cluster.

If we need to Loctite with the 425, then we will need to get some on order. I don't have it available here. We will watch the parts for deterioration and replace if needed. I will have to get an order in for the 425, then we can do any of the printers that have not been done yet.@Shawn how many printers have been Loctited so far?

david.hall added a comment to T7968: Y belt mount fasteners falling out in cluster.

Sorry, 220 to 247 range. We already Loctited the screws in Cluster with the 220 Blue Loctite

david.hall added a comment to T7968: Y belt mount fasteners falling out in cluster.

@logan and @tutley , could you confirm the blue Loctite # I show all the blues being in the 240 to 247 number range. We definitely don't want to go with too strong a Loctite. Plenty of experience with that issue!

  1. Parts will have to have an established quality parameter. ie; cosmetics, strength .. and any other requirement that the customer will have. It would be best if one part is produced and then approved before moving on to production of a part. Otherwise time and resources will be wasted. This is where tolerances will have to be verified by a quality control, either with michrometer, ruler,etc...
  2. There will have to be a quality inspector/printer operator, That will be responsible to monitor the printers while operating for warp/lift, bead height, stripping, Z offset, etc. This will ensure that the printers are doing their jobs properly.
  3. Printers will have to be maintained by printing established calibration prints, ie; Z resonance tower, overhang test, dimensional accuracy test... This is the only way to get printer repeatability and part repeatability.
  4. You will have to establish guidelines for tolerances. Knowing the needs, layer height affects print time, speed of printer for the quality required affects print time, verifying that these variables are formatted into a plan for calculating cost. This is tied to point#1.
  5. You will have to establish how to verify files for excessive manifold errors and valid stl files, or you will get files that you will not be able to print. You will have to verify that the prints that you are receiving will be able to be printed, ie; that the materials can be printed together, have materials with like values in temperature (great differences in material temp will cause dual prints to fail adhesion to each other).
  6. Establish how you will track scrap.
  7. Packing and shipping of delicate parts will be a variable.
  8. OHAI development will need to be done with the support of Tech support as they will have the most experience with customer requirements and issues. (which should drive demand of customer needs)
