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.

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.

@EricNugent this would mean combining boms.. which is up to @bowman (and @cmerot as well) and would determine the flow...

EricNugent updated subscribers of T7784: Taz Pro Tool head Ohai.

@MichaelM I personally did not have any problems with the actuator cover. Was not aware we had two different BOM's for the same part with only the actuator cover removed. @DaniAO @tutley @west would there be any problems getting rid of one of these BOM's. Alternatively, if a step by step of preferred build method can be written up or a meeting can be scheduled to build them so I can write a step by step that will help save a lot of time and frustration on making OHAI content.

@EricNugent moving the idler clamps isn't a big deal. But the Actuator cover does cause some issues. It makes it difficult when you are putting the motors onto the motor mounts, and we would have to do a BOM change. The actuator cover is on the BOM for the second half of the build (AS-TH0074) . If we put it on then we would have to add it to the BOM for the first half build (AS-TH0073).

@logan @MichaelM I added the actuator cover to when we install the actuators since I figured it would aid in protecting the ribbon cables and helped the work flow, same with the idler clamps. Is it causing issues with assembly for these units?

MichaelM added a comment to T7784: Taz Pro Tool head Ohai.

@MikeR We have always put that part on close to the end. The BOM for the final build (AS-TH0074) has always had (PP-ISOO81) on it. And the OHAI has definitely changed. Some things are in different order, for example the idler clamps (PP-IS0082) & (PP-IS0083) are put on in a different spot now too.

@MichaelM that was the way we built the betas and how I had originally trained the production team how to build it. I'm not sure why that part is on a different BOM. Is there any particular reason you put that part on at the end? As far as I know the ohai hasn't changed for a while.
