SparkFun announced they are going to have a Raspberry Pi sale for Pi Day (https://www.sparkfun.com/PiDay2015) and $25 for a Model B sounded like a great deal. Then I started to think, that's actually 2 generations old now. So maybe it's just a reasonable deal.

So I poked around and sure enough you can nab a Model B+ for $30 (with free shipping) that isn't on sale. Assuming you'd pay a couple bucks for shipping from SparkFun and a couple bucks for the USB hub this seems like a good deal to me.

<p>Compared to the Model B, Model B+ has: <ul><li>More GPIO. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model A and B.</li> <li>More USB. We now have 4 USB 2.0 ports, compared to 2 on the Model B,

I ran into Scott at Menards in Beaver Dam and we chatted for a bit about 3D printers and the Maker community. I told him about this group so maybe he'll look it up.

The Facebook groups tend to be more active.
Maker Meetup has a community and a group on FB. Community is for idle chatter and the group is more "official" announcements.

Any locals interested in buying my MakiBox?
It still technically "works" but the hot end and extruder are extremely moody. There is a decent enough community around it of people who have modded the thing to death and are getting good prints.
Make me an offer I can't refuse.

It'll be in my basement awaiting the day somebody is ready for it's bits. Even if that somebody is me.

After weeks of confusion I figured out I needed to increase my hot end temperature to get a worthwhile print again. After printing the first half of the spool without any issues I never guessed it'd be the problem.

Does it seem fairly normal to do this to account for changes in plastic over the length of the spool and atmospheric changes over time or should I assume this is the beginning of the end for my hot end as it succumbs to the impending heat death of the universe?

I was printing Orange MakiBox ABS at 234 (the temp suggested in the configs) and now I'm running it at 240.

Small leaks happened with my longer lasting hotend.. I doubt that's the cause of your problems.

Capturing to a stream¶. Capturing an image to a file-like object (a socket(), a io.BytesIO stream, an existing open file object, etc.) is as simple as specifying that object as the output of whatever capture() method you're using: import io import time import picamera # Create an in-memory ...

Anybody want to buy a used Makibox HT in the US?
It is still stock everything (zen wheel and hotend functioning) but the hotend won't hold a consistent temperature for me.
Make me an offer I can't refuse.

I'd post it in the buy/sell part of the Makibox forum but I can't get any emails from the automated systems to reset my password or create a new account.

If there is enough demand/interest I'll create an eBay auction for it so you can be assured the buyer protection you get from eBay and PayPal.

PID tuning is now enabled in 5D F/W. It might help.

I seem to have a hard time making more than one good print a day. I haven't been able to figure out if there is a pattern yet or if it is just my lot in life. Has anybody else has similar issues?

Maybe I need to let the extruder and bed fully cool down between all prints?

Edit: I have an HT with stock everything.

Before I post a new thread in the communities it looks like increasing the temperature on the hot end may have (knock on wood) solved the problem. Odd since it was working fine previously. I set the temperature to 240 and it seems to be doing much better.

Maybe I was expecting too much from a $300 printer. If I resign myself to knowing it'll never print anything up to spec for engineering standards (square) and instead use it for experimenting, toys, and art it's much more fun.

What's weird about the Makibox +Tim Bertram is that the things that make it fail could be solved (I think) without much extra cost, and are problems that are relatively well known and solved in other printers.  Unfortunately addressing these shortcomings is starting to look like more work than simply building a better printer.  

My plan is to work with it until I have all the parts I need for my Tantillus project complete.  If I haven't made substantial progress on the Makibox by then, I'll be harvesting its motors and electronics for the Tantillus :)
