Like others, I'm a "candidate" some time in the future for cataract surgery but I'm curious:

Do people who have worn glasses for years actually stop wearing them after the surgery "because they can"?

I've worn glasses for nearly 70 years and I would feel naked without. In fact, ageing meant that my original short-sight became more and more far-sight to the point that, a few years ago, I could do without glasses for distance - albeit with some minor astigmatism. Nonetheless I continued to wear glasses because of the injury protection afforded by the (polycarbonate) lenses plus a certain, inherent, amount of UV protection. (Plus the lenses lend themselves to self-darkening treatments).

Since no one has mentioned it, you are going around the chuck tightening all the jaws evenly - not tightening from a single position?

Here's a Canadian Trucker driving in the US. He says he was involved in an accident ("not my fault"  ) and was sent to a hospital to be tested for alcohol/drugs. While he was there he saw several people turned away from CV19 testing because they couldn't afford the test.

I don't know why this was such news to him but it seems to to have incensed him enough to tell the world via a video .... which he apparently made while driving his truck with his phone lying on the dashboard.

Distracting or what? Now, about that accident ....

Thread: Amazon Prime scam?

There is also the "near scam" from Amazon itself ..... where they decide to give you a free trial of Amazon Prime (and lately the Amazon Mastercard) where the default is that you accept and the "Refuse" option is very nearly hidden.

Here's something that I had recently. This was on a generally reliable machine with material (PLA) that has been good. (It's all supposed to be a single column). I hadn't expected trouble so I printed it again without changes. Exactly the same result.

When I investigated, I found that, instead of my normal, ubiquitous, 0.4 mm nozzle, I had installed a 0.3 mm nozzle in error. The slicer (Prusa) was set for a 0.4 mm nozzle.

I fitted a 0.4 mm nozzle, ran it again and the print was fine. (I could kick myself that I didn't leave the 0.3 mm nozzle in place and change the Prusa setting to match it).

Martin, I don't doubt there may be some spreading effect of the plastic but it wouldn't make sense for every nozzle manufacture to apply his own correction to the hole diameter if needed. Much better to drill the nozzle to nominal so that everyone is doing the same thing and have any correcting done in the slicer software. It's always referred to as "nozzle dia/size"

In any event I checked a number of nozzles today and all looked a bit small so I tried running a #79 drill through by hand. It went through quite easily and left me with a nice clean (and round) hole.

CE - this whole thing kicked off because I was dissatisfied with the print quality on one machine .

I do know what it's like to run a .3 mm nozzle (by misteak) with gcode sliced for a 0.4 nozzle and the result ain't pretty.

(The video seems to be the kind Neil's complaining about so it may not last long).

I didn't (difficult to do plus I never thought of it) XD.

However my quick calculation on the back of a tear-off from my Dilbert daily calender came up with 0.0015mm as the expansion of a 0.4mm hole over a 200 ºC temp range.

Not that I'm very good at those calculations any more (another sign) so feel free to correct me.

I don't think that's what I'm seeing. I'll look for a very small drill tomorrow and if I find one I'll run it through a nozzle and see if it resizes it - and if so, see if it make any practical difference to the printing (with Cura set to its current value of 0.4 mm).

Yeah ... you're right Nick. I did think of selecting the but and just sharpening that but I think it would look a bit artificial with this picture.

OOPs! Sorry ladies and gents. What I took to be a #80 drill was actually a #60. Failing eyesight ... symptom of current lack of infinity-breaks.

I can't find a #80 but the optical comparator info would still seem to apply.

Just out of curiosity, I took one of Nick's images and sharpened (the lightness layer only) in old PSP.

Whadaya think. I did use quite a lot of sharpening since I was only doing it to the lightness layer not the total image but I may have overdone it a little.

I recently purchase some 0.4mm nozzles thus.

The ones I was sent were similar to thus.

I have plenty of the latter which I can manage with but are longer and not really ideal in my situation. hence the order for the shorter ones.

When I looked at these, it seemed to me that the bore looked considerably less than 0.4 mm. A check with a B&L Optical Comparator indicated more like 0.3 mm or even a bit less.

A #80 drill .34 mm wouldn't touch it.

However, every other 0.4mm nozzle that I have around (of various types) seems to be the same so it doesn't seem to be a case of mis-marking on this particular batch.

Am I missing something?

Thread: Yipee the F1 is back on
29/06/2020 17:25:19

As usual I think I'm running counter to prevailing opinion but to me what's wrong with F1 is trying to make it "exciting" to the fans by all kinds of artificial stimuli. That, and playing to the mini-teams by limiting the others in terms of costs.

I'd rather see it as in days of yore, when it was considered a sport rather than an "entertainment". Wide open, do as you like (within reasonable constraints); spend what you like; test/develop as you like, when you like; pit activity at teams' discretion. And may the best car/driver win.

I've followed F1 since the 50's but I only watched maybe a quarter of the races last year. I likely would have watched fewer or none this year, CV notwithstanding.

Now they want to use it as a vehicle (sorry) on the current social-change bandwagon.

And can you also post instructions on a subject that too many find impossible, the correct orientation of photos. Gets tiresome turning the screen sideways or upside down.

If you have Meniere's and a fixed monitor, you don't turn anything sideways .... you just move on.

Other than that my personal pet peeves are: misuse of the message quoting system and people who prepare messages/responses separately in an editor, then paste them using tiny fonts. (And yes, I do know how to enlarge print on my screen but why should I do the work if the poster can't be bothered?).

Wonder if any of the massive, wooden tripods that were available from war-surplus dealers in the 50's and 60's are still around.

Ideal for something like this I should think.

The next job is to obtain a couple of handles and I shall try to buy plastic ones with holes already made.

... an ideal project for a 3D printer - trust me, I know.
