logan added a comment to T4120: Cura freezing 3.2.29.

Yep same steps, basically every time I abort a print (wait for moves to finish) and then attempt to restart the print. If I don't want CuraLE to freeze, I must disconnect, power off the machine, power back on, and reconnect before attempting to start another print. Otherwise it freezes as soon as start print is selected and the print doesn't start. I had not noticed this issue before starting quiver, but I rarely print from USB anymore.

logan added a comment to T4819: Interconnect housing adjustments.

Received test part from @west The adjustments worked ok, the bed power retention could stand to be a touch tighter. Adjustments made to exit holes helped the bed harness but is now a tad too tight on the bed power harness due to the sticker on the harness in that location. May still be workable.
Widening the holes helped a fit the part over the stand offs much easier.

logan added a comment to T4718: Remove built in supports from printed parts.

we don't yet know how the generated supports will effect production quality and if it will increase or decrease production material waste.

From my understanding he's been manually removing the supports in blender for some time in favor of CuraLE's capabilities.

I feel like learning FreeCAD (yeah, i know... its FreeCAD, I'm sorry) would be worth it in the long run.

Depending on where/how in the model tree the support gets added can make modifications difficult.
I could be wrong but I don't think Eric has time to handle all of the slicing in addition to what you're requesting. Nor do I think he should have to.
The efficient option here as far as I see is to leave built in supports out of the model, if generated supports are proven to be insufficient he can request built in support be added if necessary on a part by part basis. I wasn't suggesting a ban on built in supports, it will always be an option.
This would save him time, that's the bottom line.

logan added a comment to T4718: Remove built in supports from printed parts.

Do we even test supports while developing profiles or do we just roll with the defaults? Based on the behavior of default profiles with supports, I'm guessing the answer is no?

Wed, Nov 28, 11:58 AM · Quiver
logan added a comment to T4718: Remove built in supports from printed parts.

AFAIK, Eric is not familiar with FreeCAD. He uses blender anyway to arrange parts on the build plate for parts where multiple are printed on the bed at the same time. He also is usually quite busy with slicing, having to modify those supports (model changes) would increase the bottleneck.
I know what you mean about supports adhering to the build plate, I struggled with this until I found the settings governing support speed, especially with the first layer. I hated Cura supports until I tried it in CuraLE.

the supports do not have the ability to have retractions

What do you mean by that? It does retract after completing the support portion of a layer before going back to the part and while moving between support sections from my experience. Otherwise it would have drag-overs across outer walls.

logan added a comment to T4729: Change amount of hd-ms0060 m5 insert long and add hd-ms0158.

I think having them all the same would be beneficial. If we get the hole sizes to the previously determined best fit we should be good.
The bed mount chassis currently use an M-5 long insert installed from the bottom of the part, if going to a short one we may want to make a larger bore on the bottom so the insert doesn't have to be pushed through as much plastic before it gets close to the top.
I don't forsee any issues with using the short M-5 with the Y-Corners after the hole size is corrected.

logan added a comment to T4723: M5 insert hole in Y-Corners too large.

@west I know, the Olive ones are bad too. The response received when this was brought to attention (years ago) was that its fine if the insert pulls out and becomes flush with the metal plate, because it will still keep the Y-corner from rotating. While that is true, I don't think it should be standard practice to expect an insert to pull forward from its installed position.

logan added a comment to T4718: Remove built in supports from printed parts.

I am tossing my vote in the hat for removing the built in supports. I trust @EricNugent's level of experience, as he does ALL the slicing for our printed parts and has for some time. If he says its better not to have built in supports, he's probably right.
From personal experience, Cura supports are better. This may not have been true with legacy cura, but CuraLE has many more capabilities.

Wed, Nov 28, 8:14 AM · Quiver
logan added a comment to T4718: Remove built in supports from printed parts.

@Steven Based on the feedback from Eric, no. In order for the built in supports to be effective he has to use a layer height which allows them to break away cleanly which isn't always the best layer height for that part. @EricNugent may be able to explain a little better.
My thought was if the CuraLE supports work well we could avoid having to make multiple adjustments to those parts before we find spacing that works. As of the moment I believe it would be too time consuming to accomplish that based on the current state of the Slicing Queue and the urgency needed to get the Alpha builds complete. It seems to me would be a more efficient workflow for everyone involved if we just remove them.

logan added a comment to T4712: TAZ7 Alpha Build Critical Dimension Tracking.

I noticed we have one spot for measuring rod spacing. Wouldn't it be more helpful to know top/bottom spacing?

Y Corner Left Spacing to Extrusion (front and back):
Y Corner Right Spacing to Extrusion (front and back):

What is this referring to?

Repeatability of the Z-Axis:

Do you have a process for determining this measurement and how it should be stated? Just the repeatability of the Z-axis axis or of the actuators/z-axis combined?

E-Steps:
Z Probe (Each Corner):
Z Offset:

E-Steps on aeros are always 420 until a reasons exists to examine otherwise.
Z probe: are you requesting the output of a bed leveling matrix? Why? It is not repeatable. We could compile averages and see if we see our beds tilting one way or the other but that sounds time consuming and unnecessary.

@oliver I might be able to work that one so it is reversible, but historically I think assemblers doing inserts have preferred a simple trough style. They're also quite a bit easier to print and more versatile, sometimes can be used for more than one part.
We can try a couple different methods when we get to it and see what they like.

While holding the rods in against the jig, and pushing down on the Y-End plate, yes.
I can add material to hold the spacing between the extrusions more similar to the current jig if that would suffice. That is the only difference.
At that rate I might just redraw the current jig in new part design and modify any needed dimensions.

logan added a comment to T3608: Y-axis assembly jig.

@west

Why are we positioning the motor mount relative to the Y end plate based on one hole? The part could be up to 1.5mm off if we locate it on that hole. And aligning it with that hole wont position the belt to be straight since the belt mount holes have a +- 0.75 alone +- the tolerance stack. It seems like we are adding an extra step and complexity for not much result

@kent suggested that we should make a fixture for placing the Y-Motor Mount on the Y-End Plate. I just couldn't think of another way to constrain the part as requested. How do you figure we could be off by 1.5mm? The example pictured was to illustrate the concept. The idea was to have the hole tapered and sized to a dowel pin that would fit through the threaded hole in the end plate.

With the Y assembly jig, I see where you are going with it but I think it would be better to position the extrusions and base everything off of that, the extrusions should set the position of everything

Is there a good reason to do it any differently than TAZ 6? The goal of this jig was to accomplish the same task as the similar jig currently in use for TAZ 6.
Are you thinking just a spacer jig between the two extrusions? Then the issue of locating the end plates would require yet another part to that.

Is ~/Projects/taz-quiver/Production_parts/TAZ7_assembly/Assemblies/Final_mechanical_assembly.fcstd that was removed in the above referenced commit sufficient to measure from regarding those dimensions?

That would look off though because the sheet metal hangs over, probably not kosher

@west I was referring to eliminating the M5x10s securing the printed part to the extrusions, do you think the 4 M3x10s are sufficient?

Correction, I did specify the orientation of the bed fingers on both OHAIs
so edit to https://ohai.lulzbot.com/project/lulzbot-taz-5-aerostruder-tool-head-installation/accessories/
is actually:

6A
Remove the four original 3D printed bed corner fingers using a 2.5 mm hex key.

6B
Using a 2.5 mm hex driver and the screws removed in step 6A, replace the bed corner fingers with the 3D printed lower profile bed corner fingers.

The recessed side of the bed fingers should be facing up.

Chop it off?
Do those fasteners contribute to the rigidity of the frame?
I think there's enough securing the printed part to the top plate that we could eliminate these four fasteners without losing anything
