Once, with .139 yesterday. was changing filament on extruder 2. want me to try to replicate?

@marcio I have s beta and ran the test with .142. I let it run for a while without selecting STOP, so cycled it 4 times. It cycled through test 1, 2, and 3, including a momentary message of "Watchdog should bark" for each test without thermal runaway. If you need the unit, let me know, and I'll bring it over.

@karrad is responding to a large customer of ours to make the product better at very little cost. @tutley has provided two ways on how to solve the problem. Please implement in the most cost effective approach to one of @tutley solutions into the product ASAP. The customer specifically needs it securely attached to the printer, not contained separately in a toolkit. Thanks!

Test on Extruder 2 using 2.0.0.135 with Cura 3.6.11 on Pro Beta using standard production fan shroud. PLA, standard profile, spiralize & smooth, 0.25 layer. Build plate initial layer temp dropped to 60C, then 45C thereafter; fan 100%. Very clean bottom layers. Equally good results!

Mine is a beta...

new tests with 2.0.0.135 with Cura 3.6.11 on Pro Beta using standard production fan shroud:

Yep, it was in. Issue is cable has lots of slop in it to inadvertently move around and end up with rubbing...

@eBeardslee In your absence, the team decided to name the standard hardened steel tool head "HE". Please roll this into all pertinent marketing material. thanks!

On my beta Pro, I flashed .135, upgraded to Cura 3.6.11, used existing production fan shroud, ran the automatic nozzle offset and printed the following calibration print using standard PLA profiles (except .25mm layer) - without any tweaks. Black is left over burned residue from previous. Best print yet!

New profile is much better!

Updated new firmware to Beta unit, loaded these profiles, and it's looking much better. Will post when done. Thanks! any changes to PolyDissolve profile?

Print below with 100% fan, Z override on support. A bit better.

Thanks Marcio.
I walked away from my print, went to a meeting, and when I came back it had this error message "Probing Failed". So I didn't know if it made it past auto-leveling or not, but nothing was printed. If it would have said "Leveling Failed" (15 CHAR), I would have known immediately what was wrong - probably dirty nozzles. Not sure if this terminology is helpful to others though.
thanks again for the education.

Thanks for the clarification.

1. Regarding <MESSAGE>, Do we have the diagnostics precision to identify the difference between an auto-leveling failure and other failures? If so, then "Probing failed during auto-leveling" (35 char) for TAZ Pro will help the user.
2. Can you list what all the error codes are?
3. Does "Please reset" always mean turn the printer off and back on? If so, "Switch off/on" might be clearer

We aren't able to create a couple of dialog boxes to handle common categories of errors?

Please add Hob

PLA

@adam any updates here? We need these now so we can start printing

@DaniAO that's better than "strengthening"
TAZ Frame Reinforcement Kit

I recommend: TAZ Frame Strengthening Kit.
@eBeardslee please weigh in on Fri 5/10

Approved as noted.

Thanks Adam. sounds like minor issues that can be reviewed/decided at the meeting.

@DaniAO please re-assign owner to @eBeardslee for next steps. thank you!

@adam do you have a final spec sheet, etc. we should look at in prep for sign off?

HS 0.5mm

Repo is fine

so based on our discussion this morning, it's LulzBot green. Green is for 0.5mm nozzles, light gray for 0.8mm, dark gray for 1.2mm
Wording on green part may be "HS" with "0.5mm" below it as raised lettering. This would distinguish from SE 0.5mm on Mini2
@eBeardslee this would also affect naming on existing HS tool head. Recommendation would be existing tool head becomes HS 0.8mm. This one becomes HS 0.5mm. Thoughts?

@Orias does the Froala Editor affect any end-user consumption of information on the web that forces them to accept a license? If not, then the end user still has a FLO experience. And if there is a license requirement to a web user, do they have a choice to accept or reject?

Is the above ready to go?

As we agreed in the Planning Meeting today, MER/Planning will provide basic content of instructions with a simple/rough draft photo to show what's intended. Then Michael will be the point person within Marketing to ensure it is put into final form (both instructions, layout, as well as photos), and ensure MER/Planning reviews prior to final completion.

@nickp, this was forwarded to @mcoronado to decide on Monday, but he is currently out at SEMA. (thanks @DRobertson !). My guess is he will want the silk screened image reduced in size so the new holes will not interfere. stay tuned... thx Hob

I asked him to weighing today even though we are at the show

yes

@DRobertson Looks great Dave! ship it!

Tests:
ASTM D638 for tensile strength, elongation at break
ASTM D256 for Charpy impact strength
Also Glass Transition Temperature (not sure of test, but some refer to slope of temp increase to determine as 10 deg C per minute

@DRobertson add Megan and ask her to answer Adam's question about Sales...?

Looks good!
Since this will be used more by enterprise/advanced users, I'd replace our rocktopus with more of a corporate look & feel. Perhaps Aleph Objects, Inc., makers of award winning LulzBot 3D printers, @eBeardslee thoughts?

Josh, nice solution! by raising it 3mm we get that whole beveled face for the logo.

See if we can pick a size that fits something on the printer that might need to be tightened or removed someday, so they can try it out immediately....

.... and since we are selling dual print capability, we should demonstrate it in our labeling....

Totally agree. We should act like the leader and make it clear "who we are/what they are using" in areas where typical photos are taken and where highest use occurs!

Note the strongest new material for these tool heads is colorFabb PA-CF, a carbon filled nylon. See https://shop3duniverse.com/collections/3d-printer-filament/products/colorfabb-pa-cf-low-warp-700-g
Note the sample parts they show - functional machine-type brackets. Rather boring, but just a case in point

Consider giving the user 2 objects to choose from. A flat wrench with hex head sizes for the printer would be cool. Maybe a second one that is for personal use?

Copied comments from T3250:

Eric and I are going through some stuff right now. However, in the short term, it appears the hardened nozzles on these toolheads enable high-strength compositefilaments (different than durability and toughness). Case in point of tensile strengths (MPa): PolyMide CoPA=66.2, colorFabb PETg Econ=49.0, colorFabb PA-CF=107.0, XSTAND-GF-30 =102.0. This is an average tensile strength of ~81 Mpa. However, there elongation @ break is quite low - 13%, or more on the brittle side. This is in contrast to the MOAR products that are durable and tough, but have greater elongation @ break: probably average around ~55MPa tensile strength, but 3-5X the elongation.
