tutley added a comment to T8299: use flanged hex head M5x10s for Z lower to frame.

@logan i think if we do roll forward with this then we will need to include the 8mm wrench

tutley added a comment to T8299: use flanged hex head M5x10s for Z lower to frame.

@logan i am not fully convinced that this is an improvement. you will still end up with cross threaded bolts/screws as it still happens even with direct access to any fastener. This only introduces yet another required tool and another fastener to keep stocked.
And yes hex drivers wear out but that happens with hex cap screws regardless.
Currently you can work on any part of the frame assembly with 1 driver. A few months ago we were consolidating all the hardware, specifically for manufacturability and RMA purposes.
Also this introduces an expensive new tool to add to the tool bag.

tutley added a comment to T8299: use flanged hex head M5x10s for Z lower to frame.

it would actually solve the problem for proper access. You can get at the fasteners much straighter with the motor not attached. This is the exact same as what we have done for all of Taz5 and Taz6

tutley added a comment to T8299: use flanged hex head M5x10s for Z lower to frame.

i think we can assemble the z lower, upper, and x end with z belt and z idler attached, just leave the z motor off. This assembly can go on the shelf held together with a large rubber band or two. then the assembly goes on the frame, with no z motor attached you will have access to the mounting screws to torque them properly, then the z motors go on and the z idlers get fastened down.

tutley added a comment to T8023: Additional 5a Nano Polyfuses.

My recommendation for an alternative to the printed parts would be something like this https://www.hawkusa.com/manufacturers/hammond-mfg/enclosures/plastic-enclosure-box/1551nbk?gclid=EAIaIQobChMI5I3kl_OE4wIVErbACh1FXgRNEAQYAiABEgJo8fD_BwE mounted to the inside of the flat electronics cover with a strong adhesive patch. This way the user could set the cover down on a flat surface and open the box to remove the spare components.
I would advise against a vinyl bag or similar container that does not seal, as the machine may not always be in the upright position during transportation. Also a bag is likely to get damaged after removing the spare fuses a few times. (this is the military that requested this feature, so it should be robust)
The last thing we want is for there to be loose components rattling around inside the electronics case.

@david.hall @cmerot Just FYI there will be more custom printed parts coming with kangaroopaw and its follow up. Is there no current plan to expand clusters production abilities?
We will gladly look into alternative solutions for this fuse holder. However given that TAZ6 will be out of production soon and there are multiple shared parts between quiver and redgum (soon to be more with current ECO's), it seems that 2 additional parts that take 30 minutes or less should not bumping the cluster into a state of unsustainable manufacturability

tutley added a comment to T8023: Additional 5a Nano Polyfuses.

@logan the only fuses i have ever seen blow on the rambo is the little nano fuse
So i dont think it is necessary to include the larger car fuses
Also the fuses could pretty easily fall out of the vinyl sleeve during shipping or while the machine is being moved.
This was a request from the US military as they often have to replace the nano fuses. They jump out of planes with these printers and im sure subject them to rough transportation.

tutley added a comment to T8215: Error on Quality Assurance Record Sheet in Steps/mm (X/Y).

The 1600 steps in the documentation is incorrect. it should be 100
the 100 steps per mm in the firmware takes into account 16th microstepping.
the formula is:
steps/mm = (steps per rev on motor) * ( microstepping) * (1/ belt pitch) * (1/ teeth on pulley)
its a 16 tooth pulley, 2mm belt pitch, 200 steps per rev motor, 16th microstepping

I have 2 of these on my desk. I ran some initial tests, but could not find an obvious reason for the under extrusion.

I have also ran 100 mm of filament through both extruders and they were dead on at 100mm actually extruded.

@eBeardslee i have seen a lot of printers where E2 hits the right edge of the cube but doesnt miss the top.
I just looked at @samantha 's machine and it appears to barely touch the proper location. I can see how though tolerance stacking some would entirely miss the top of the cube
@marcio can we update the E2 z plunge location for auto calibration? Auto cal finds E1 first, and then plunges for E2 and it seems the x distance is too high

tutley added a comment to T7658: AS-PR0121 Taz Pro Y Single Bearing: Too much drag when assembled on the Y-axis.

@david.hall that is good! I was speaking with @ west about this and the bushing bore is undersized so that when it is tightened to the flat surface there is a clamping force applied to the bushing. I think this should be adjusted to alleviate the excess drag on the axis.

@kent I believe it is Baldwin's drawing so that the interference between the tooth profile of the spur gear and the hole for the set screw in the pinion gear is minimal. this will help prevent broken spur gear teeth. Ideally there would be no interference between the hole and the spur gear teeth.

I just spoke with @MikeR over here at Rockies, and he showed me the problematic part.
In this particular instance, the threads have been stripped out on the side that the screw engages, so the part is damaged beyond usability.
He was going to countersink the locating holes a bit more to see if that would help, but i dont think that will make any difference.
There are just no threads left to engage.
We discussed switching to a longer screw, however the m3x50mm is the longest screw offered in the blue dyed option.
