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!

@MikeR the rod spacing from the inside edges of the rods should be 17.5mm +/-0.075

@MikeR Here are some target dimensions for you:


Because these dimensions have a tolerance, you will of course need to measure the raw part before torque is applied.

logan added a comment to T8289: Pro tool head OHAI.

@tutley @MikeR Unfortunately our in*oz torque wrenches (CDI 61SM) only ranges from 20 to 100 in*oz. So 1.25in*lbs is the lowest we can reliably go with these drivers.

Jul 3 2019, 2:26 PM · Quiver, Assembly Instruction Content Request
MikeR added a comment to T8289: Pro tool head OHAI.

@tutley will the cad drawing show the desired distance so I can try the 1in*lb value and check for deflection. Is there an allowed amount of deflection before we start getting carriage binding?

Jul 3 2019, 2:06 PM · Quiver, Assembly Instruction Content Request
tutley added a comment to T8289: Pro tool head OHAI.

I think 2 in*lbs is okay for these fasteners (as well as the HD-BT0041 in step 5)
the problem is that if these are over tightened it changes the spacing of the rods in a way that will cause the motor mount carriage to bind.

Jul 3 2019, 1:51 PM · Quiver, Assembly Instruction Content Request
MikeR updated subscribers of T8289: Pro tool head OHAI.

@MichaelM I am hesitant to remove a torque spec without having a good alternative. This would just make it an arbitrary tightness. 2in*lbs is the lowest we can go. @tutley @west can I get your input on this issue?

@karrad We have cosmetic QC standards that we adhere to such as: no squish, good layer adhesion (not measured with any specific tools, just by appearance), minimal overhang droop (also not a specific measurement more regarding appearance), no color inconsistency, no warping, good initial layers and a good surface finish.

@david.hall The parts we verify for production are mainly for Cosmetics and Strength testing. @kent may have more information on Torque out and Pull out numbers, but I am not sure if this is relevant to cm mfg.

@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.

@cmerot At the moment we have one TAZ 6, one TAZ Pro, and four Mini 2 printers designated for CM. I've also been occasionally using one of the TAZ Pros over at Mountain for longer multi-day prints as we cannot have prints running overnight here at Lago. I'd really like to iron out all the intended processes, especially with regards to QA/QC, which I think we can leverage a lot of knowledge/experience from Cluster for.

@lisa Further clarification - excellent. This is great to know and I am glad to hear we have soft launched and Contract Mfg is independently staffed. I suggest Greg coordinate a meeting with Franklin, you and me (Grant optional), and we can get Franklin started. By the way, how many printers of which kind will CM require over the next few months?

I talked with Grant this morning and he clarified a few things for me. He is looking for an OHAI procedure to cover the entire process from receipt of order through printing, post processing, QA, shipping, closing and invoice. Most importantly, when we start contract printing service, we will subcontract to Z Verse or 3D Solutions. So they will screen parts, select us when appropriate and slice the file. With the order, we will receive from them sliced .stl files and a drawing with critical parameters defined or some other form of critical parameters definition. The order will go into Odoo and we are off and running. I didn't yet discuss with Grant, but we might want to combine our printing service with our cluster printing to leverage resources, knowledge and methodology. After printing, we will perform post processing. In advance of startup, we need to determine what post processing services we will be willing to perform, process capabilities and prepare to perform these services. QA will be performing a visual inspection for obvious defects (and we will define these in advance) and then check defined critical parameters. When cleared to fly, they will be packaged and shipped out. Orders get closed and invoiced to our contract partner.
Before we launch Franklin on the Ohai, I will schedule a discussion with Grant and Lisa to make sure we are all in agreement.

I've helped a lot of students with 3d printing their own files when I was at CSU so I know a lot of what to look out for.

Just to add my two cents here, I think it can be beneficial to operate some sort of contract manufacturing; however, I think we may be competing with ourselves at a key point in the companies growth. A customer may see more value in getting the printed part rather than investing the time and money into operating a PRO or purchasing a HS or HS+ tool-head, in order to print some more expensive and finicky materials. Additionally, we have the benefit of being predominately FDM machines which is generally a lower cost to operate compared to SLA and DLP, but once we start to price out the service for parts our 'cheap-to-operate' perk becomes less valued as customers on the fence will use the pricing here to gauge how expensive it will be to own a LulzBot.

  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)

Its been made clear as to why we need to document processes, but I think what the question/concern is that he doesn't know/have the processes TO document. We may need to pull in some one else from Cluster and possible R&D to help write the process and then MER can help put the create and document the process.

Grant added a comment to T8065: Contract Manufacturing OHAI request.

Franklin;
Just quickly a few thoughts on why we need to document. Repeatable performance on all manufacturing requires documentation, instructions, training and review/inspection. If we are to build one part 25 times for a customer - how do we assure that the part is exactly the same (or with in pre-agreed tolerances) each time? How do we assure that the surface quality meets the needs of the customer? How do we assure the individual piece part meets the tolerances agreed to? What post processing are being employed and how do we assure they meet the needs required? What is clusters current process for assuring part quality and repeatability? What materials being utilized for the part will require different process parameters. Documenting these things ahead of time will assure a successful venture as we move forward. We need to assure we quote, manufacture, inspect, box and ship properly. We can accomplish thru the OHAI process or we can have a document we develop for training.
