It works… Sort of

Finally got around to testing the FlashForge 3D printer after replacing the thermocouples.

Yes, it’s a TARDIS… Yes, I’m a geek…

Results weren’t horrible, but not as good as they should have been.

I’m not sure why but It’s been having issues with prints not sticking to the bed for some reason. It didn’t do that before. I replaced the kaptan tape, double checked the temperatures… nothing seems to help. If you look close at the model above you’ll see that on the far left corner it’s lifted up a bit where it began to release from the bed during the print run.

I also seem to be having extruder problems. I haven’t changed any of the settings. Temperature, feed rates and everything are the same as before. Going to need to do a bit of investigating. I tried two other test prints. One curled so bad I had to abort the print. The other was a rather complex object, a rendering of two people embracing, and the print quality was so bad I aborted that to

I’m not really sure what’s going on with the print temperature settings. I use ReplicatorG to generate the files and the temperatures I set in the program aren’t changing the temps on the printer. Even worse, it doesn’t allow me to change the print bed temperature at all. I’ve even tried changing it on the printer before printing, but no matter what I do it always reverts to the old settings of 220C for the extruder temp and 100C for the bed.

Fix It Day Part II

In part two of Fix It Day, I finally got the FlashForge working again with assistance from eldest son. The thermocouple monitors the heat of the right extruder went bad, and the one n the left side seemed to be intermittent. I’ve had two new ones sitting on the shelf for two or three weeks now and we finally got it back together.

And, of course, we managed to reverse the polarity of the thermocouple wiring so it indicated temperatures were going down instead of up, so we had to re-wire that. Then we reversed them so left was right, etc. Had to re-wire that…

Handy hint! Label stuff! Would have saved us a good half hour of time if we’d bothered to label everything as we took it off when we disassembled it.

I really need to replace the kaptan tape on the plate, too, but I’ve been putting that off because it’s a royal pain in the neck. Everyone tells me it’s no big deal but I’ve tried everything, looked at videos, etc. Nothing works. Always end up getting air bubbles all over the thing.

Anyway, seems to be working, so I’m happy. 

It’s Fix It Day!

Putting the MC-60 back together. Finally got around to tinkering with it. It started having intermittent issues a couple of months ago so I was using the Heil headset, which I prefer anyway so I was in no big rush to get this fixed. How the heck does something that’s been working fine for two and a half years suddenly develop a bad solder connection? You’d think it would have started acting up long before this.

Never know, though. Had to take apart the relay box on the remote control system we use to turn the outside Christmas lights on and off. We had that for two years and had no problems, now a capacitor on the circuit board had somehow worked itself loose enough to just fall off the board entirely… I suppose the solder joints were bad to begin with but just good enough to hang on and thermal stress finally forced them to let go. | Corn futures – will their, relative, resilience last in 2016?

Corn futures have fallen this year – but by less than soy or wheat. Can this outperformance last? Or will it fuel raised output, and price pressure?

Trying to figure out how the commodities markets are going to move is sort of like trying to herd cats. There are so many different factors involved that sooner or later chaos theory gets involved and no matter how good you are at it everything falls apart.

I really thought corn was going to go down the toilet when the numbers from the 2015 harvest began to come in. We’d had an increase in acreage planted, weather had been decent, yields were quite good, the market seemed poised to drop significantly… I wouldn’t have been surprised if the price fell to under $3, in the 2.8 to 3.0 range.

And, of course, I was wrong. Prices remained remarkably stable even as the harvest concluded with near record numbers.

Now everyone is trying to figure out what’s going to happen in 2016. And while there are the usual doom and gloom purveyors out there, along with the usual eternal optimists, if you ignore the extremes everyone else is indicating that corn pretty much isn’t going to move anywhere in the near future. Barring some kind of extreme weather event or something else that causes wide spread issues, the people who should know this stuff like Rabobank believe prices are going to remain fairly stable. Rabobank thinks it could hit 4.20 in the second quarter, but by the third quarter it will be dropping down to around what it is now.

Looking at the predicted acreage figures, long range weather predictions (which are pretty much a joke if you’re honest) and everything else, I’d agree with Rabobank.

There seems to be no drastic increase in demand in the works. Considering how low oil prices have dropped, there certainly isn’t an increased demand for ethanol. The only reason that industry is even around any more is because of government mandates. A lot of people, engine makers especially, would like to see ethanol just go away. (we just bought a chain saw and it’s accompanied with dire warning about running any kind of ethanol blended fuel in it. My new car… it doesn’t come right out and say ethanol blended fuel will kill it, but it comes damned close)

I don’t have a lot of money tied up in commodities so I don’t really have a horse in this race. I watch the markets mostly for the entertainment value (some of these people are, well, loopy to put it politely). So don’t take this as advice or a recommendation. Frankly I think you’re nuts if you invest more than a bit of mad money in the commodities markets.

It’s fun to watch though and try to figure out what’s going on.

If you don’t know what the COOL (Country Of Origin Labeling) was, I don’t blame you. Most of the consumers I’ve talked to didn’t even know the laws existed.

COOL required meat packers to label their products by country of origin. The consumer had to be able to tell if that meat came from the US, Canada, Argentina, Mexico, China or wherever.

This doesn’t sound difficult to do, until you realize that the product in that package could be from two, three or even more places. It’s common practice these days for meat packers to make ground beef from lean meat from one country, mix in fat from another. Or meat from two or more different countries can be included in that stewing beef or chicken pieces package.

It doesn’t sound very controversial, either. Who would possibly object to knowing where their food comes from? I certainly didn’t object to it. I liked the idea. And so do most consumers. We’ve all heard the horror stories about dead pigs floating down rivers in China or the horrific melamine milk contamination that took place a few years ago.

The people who didn’t like it were countries outside the US like Canada and Mexico. They claimed that if they had to label their meat as coming from their country, people in the US might prefer to buy US products instead. And the World Trade Organization that polices such things agreed. So Canada and Mexico were poised to launch a massive increase on tariffs on a variety of US products that would have cost billions of dollars.

So Congress, with some justification, caved in and passed a repeal of COOL on Dec. 18

I have rather strong feelings about this. I rather liked the COOL regulations.

First, consumers seem, to me at least, to have the basic right to know where the products they purchase were made. They also have the right to know what’s in them.

Second, wanting to hide where your product comes from makes me a wee bit suspicious. What exactly is wrong with your product that you feel that if people knew it’s origin they wouldn’t buy it? What are you trying to cover up?

The thing I find most disturbing, though, is that increasingly these treaties are giving outside interests extraordinary power over our internal affairs. In this case, the WTO, Mexico and Canada were able to force a significant change to US law. The Trans Pacific Partnership, which politicians on both sides of the political spectrum have been pushing for hard, makes things even more concerning, giving individual corporations the power to do what Mexico and Canada did here. A corporation could, in theory, sue a country under the TPP, forcing that country to change it’s law.

This seems to be giving an enormous amount of power to not a government which (theoretically at least) is supposed to guard and protect the interests of it’s citizens as a whole, to an entity that cares for nothing but profit, even at the expense of the welfare of the people.

For the paranoid on your Christmas giving list, Just in time for Christmas…

Just in case you’re thinking of rushing out and getting one of these, I should point out that they are all utterly worthless, so save your money. The ballistic armor police and military people wear is, despite the hype you see in these ads, not related to these products in any way. Just look at that photo of the kids cowering under those blankets… Come on, do you think those are going to provide those kids with any protection at all? Even if they did offer some protection, they don’t even cover the kid. They’re totally worthless. As are the ‘bullet proof’ backpacks, ‘bullet proof’ baseball caps and the ever popular bullet proof bible, because of course in a shooting situation that bad guy is only going to aim for that five square inch bible…

So, Grouchy – you had the day off you must have read something exciting, right?

Oh, you bet! Found this fascinating article on the development of the bailer twine knotter. It started back before the civil war, it seems with this guy named Appleby and after the war he moved to Beloit where he developed a knotter that would work with sisal twine instead of wire..

What? Oh damn, I really need to get a life, don’t I?
