Drawing delivered to production
@bowman This has been updated and should be available in the repo.
Reviewed and merged.
Assigning this to you since I don't think we want the person implementing the fix being the reviewer.
@Steven I think we can close this. We are fully discontinuing these parts and will have enough coming in to cover the transition. Our T&Cs allow us to upgrade for a fix/RMA as necessary so we don't have to worry about getting in one-off parts.
@adam is this still needed? If not we can close this one out.

We can probably close this ticket. We now have the new Hot-ends from E3D and are using them. We no longer need to use the Gunnison (FS) extruder.
@EricNugent is working on a new drawing for AS-HE0041's that are now being used.

Also, please change the name/description for AS-HE0040 as these are used on the (FS) TAZ 6 tool head and not on a v3 dual

@mbloom Yup, it should get them fixed up in the same matter.

We are also having the same issues with the TAZ's running Flexy filament. Would including the M420 lines fix those files, or would they need something extra because they are Flexy?

Sounds good, closing as resolved under 188.8.131.52
@karrad I can not reproduce this on 184.108.40.206. When I move in small incraments, the lvd will pause until the z-axis catches up then I can continue to move the axis.
@MikeR That sounds about right (as in intentional) Marlin has a safety feature that prevents large moves from the LCD. About 100mm is what I recall from that version of firmware.
@karrad I would get around 100-150 mm before it would restart. I am going to try that new firmware this morning.
Mar 4 2019
@MikeR What was the number you would get to before causing a restart?
@EricNugent With each update to marlin, there will be specific changes to start gcode required. For example in the 1.1.7 FW we needed to change the way we homed in order to take account for fringe cases of euphorbia builds for Mini 1.
@karrad that .gcode is the the start/end for the 236's. Do we have an updated start/end .gcode that we know will work across all firmware versions?
Mar 1 2019
I can confirm that problem does not occur on other versions of the firmware. 220.127.116.11, 18.104.22.168, and 22.214.171.124 do not experience this bug. All instances of 126.96.36.199 in the cabinet have been downgraded to 188.8.131.52 until we can get new slices made.
@EricNugent This is old gcode it looks, and the issue you are describing sounds a lot like the Bed Calibration stack up we ran into when first going to 1.1.9 firmware.

On further inspection of the lcd boards, I do not believe that this is an issue with the lcd since they are working just fine before they put them in the box. I think this might be an issue with possibly the printed parts having to much tolerance. If the sd card is not lined up with the slot in the metal, the sd could be sitting at an angle when all the way in. This is applying a torque and keeping the sd card to not fully sit. Will continue to monitor these parts coming from Pilot.
@kim - heads up. As soon as we have some more info we need to let Ultimachine know!

Just talked with Patrick from Quattro and scrubbed the hexagon source with 6dc8aade581f96deda5ba25e90d00b9499552ae0 and added a couple more things to the sink and break. It needs to be reviewed and merged into master. In this case I just straight reverse engineered the existing design, but there are some major DFM questions.. For example, there is a piece of hardware that needs to go into the top of the heatsink that we don't need or use, so do we need the additional cost of processing? The heat break is going to be difficult to get quoted, since it requires a laser welding process that most of our usual suppliers don't have equipment for. Last thing is the tolerances required to get the fit between the break and the sink right are super tight and this will drive up the cost of these parts, both in terms of price and the cost of the difficulty of maintaining a reliable supply of parts.
@kent Where are we on this drawing? This is needed ASAP!
Jan 16 2019
@kent looks good
@samantha I incorporated those changes and pushed it to the branch can you review the drawing again?
Jan 9 2019
step file for heat sink also pushed now
@jessica I pushed a step file for the heat break to the branch for this ticket under taz-olive, exported from Kent's file
@kent PP-MP0113 feedback:
The A datum is a theoretical axis that is not based on anything physical, with everything related to it being measured off of it. This prevents it from being able to be used in any actual measurements. A physical feature will need to be selected as the A datum to generate that axis from.
@kent what file did you base the heat break drawing on?
Jan 8 2019
thank you both so so much!
@jessica I just finished re-drawing it, there were a few errors on the drawing I posted.
@samantha - can you please point me to the step file for the MP0112... I see one but its pretty old and I am unsure if it is correct or not.
@kent changes look good
I incorporated @samantha feedback on the break and pushed a new version. Here is a pdf with the incorporated changes:
