Thread: Use of Torx Bits in Hex Skt Hd Screws
07/05/2020 16:33:31
Posted by Tim Hammond on 06/05/2020 11:22:32:

In several YouTube videos recently, including one by Clickspring this morning, I've noticed the use of Torx bits in cap head screw rather than the usual hexagon bit.



I went to youtube . Clickspring > videos > sort-by-date-latest and the latest listed was 7 months ago.

I link would be helpful.

Interesting analemma of the moon that I've never seen done before on today's APOD

That looks pretty good on a quick peek. I'll follow it up tomorrow.

Thanks, Michael !

Thread: Ideal Extruder Temperature for PLA
07/05/2020 01:59:02

210/60 °C is nominal (according to Cura) yet I have some black that will string badly at 200°C and up. 190 seems good for it. I don't think I've ever printed over 210°C. (Of course, one machine's 210°C isn't necessarily another's).

I've seen and printed some calibration models on Thingiverse but many of them take several hours to print. I was looking to come up with something small that could be printed quickly one after the other at different temperatures to give some basic temperature guidance for specific filament batches. I don't expect it to be totally definitive (even if that's possible) but some starting guidance would be helpful.

I'd also prefer something modelled locally so I have CAD files with a feature-history rather than someone else's STL that I can't modify.

No, but I do think we should work from a Sidereal clock...

Talk to Apple. Maybe they'll make you a digital version.

Thread: Ideal Extruder Temperature for PLA
06/05/2020 22:41:52

There has been a number of comments over the months that ideal printing temperatures for PLA (and other materials probably) vary with supplier, batch, colour part configuration .... and possibly day of the week and whether there's an "R" in the month.

It has me wondering whether it's possible to come up with a small part that could be printed at different extruder temperatures when starting a new reel. Possibly multiple copies of the same part with the different temperatures printed on, to avoid confusion when comparing the resultant parts.

I wonder if that's useful and what such a test part should look like. Ideally, it should be something that could be printed in 5 or 10 minutes.

the first quarter evening moon is reversed in Southern Hemisphere with the light part on the left, and vice versa for the last quarter early morning moon.

Isn't that due to the reversal of the observer - facing North instead of South?

Six of one, half dozen of the other

I can get the same effect by standing on my head!

Hmm .... so are you also one of those people who think, since the year is actually 365.25 (rounded) days long and to correct that we add a day every 4 years, that after 2 years we'll be 1/2-day out and midnight ought to occur at midday?

Mick, now that I re-read it (several times) I think you're probably right and it is referring to the micro-usb.

dont know ... don’t those all have the seam in the metal on the bottom ?



If I knew which side was the bottom* I could answer that wink

This is really all about that micro USB connector thing, isn't it?

 

Actually, I read it as being mostly about the standard USB connector at the other end of the wire ... the one that looks the same on both sides and doesn't go in on the first try; doesn't go in when reversed; then finally goes in when you reverse it again.

My favourite Dilbert was this one from about 20 years ago:

Thread: Tuning up my Versatile Vice
02/05/2020 18:52:20

Mine is simple: a block that is tightened in the vice jaws with a tang that projects through the gap in the base and into a table slot. I then load the whole shebang against one side of the slot while I tighten the mounting screws.

Mounts in seconds, is plenty good enough for anything I do - and I don't have to clock.

.......printed in lilac text on a grey background.

Sounds like the early days of microprocessors when purchased source-code (assembler or machine language) was printed like that to avoid photocopying and passing along.

Is it just me whom this strikes a chord with ?

Ah... just seen your second post!

Wouldn't you know it .... just when you're locked in and can't get out to the opticians.

I'll leave now.

I don't see how it would do this if the x and Y homes are off the build plate. I presume it can be done, since you obviously have.

I’m sure mine comes down on the z axis until it hits the limit switch - the bed is levelled on that pisition, so it should make no odds where the home point is, in reality.


... er .... well .... so does mine now you come to mention it. I had this fixation that the z-axis worked differently to the others.

Put it down to age, addled brain and forced isolation.

Posted by Neil Wyatt on 28/04/2020 15:35:34:

My setup now actually places the home position just off the buildplate, a minor inconvenience when checking the z-height but a bonus as nozzle purges don't make a lump on the buildplate.



I'm curious about this since it was my (possibly quite wrong) belief that printers home the z-axis (after homing x and y using the limit switches) by reaching down and touching the build plate; then withdrawing a few steps and approaching slowly to confirm.

I don't see how it would do this if the x and Y homes are off the build plate. I presume it can be done, since you obviously have.
