After a couple of weeks apart, my printer is back together

I took my printer apart to try to figure out why the bed isn't level. The Y rods where sitting crooked. I popped them out, rolled them on the counter-top to make sure they where still straight and put them back together. It's better, but still not perfect. I think the Y rod mounts are maybe stretched and the Y carriage is slightly less than perfect so they compound each other maybe.

I don't really know. I put it back together anyhow.

I tried to un-solder one of the power mosfets as I think I blew it, and that didn't go so well. I lifted the tracings off of the circuit board. I really don't like de-soldering braid.

The kitchen counter gets cluttered up with kitchen things. Fancy that! Time to move my printer off the counter!

I really buggered up the tracings when I tried to un-solder this mosfet. They fell right off. No Good.

I think I can top solder the mosfet. Tried it at least. I may need a new board soon.

The printer still works! A good sign. Now to print my backlog.


Huglekulture raised bed

Yesterday I took the day off to spend with my daughter. She'd gotten home from nearly a month in Florida visiting family. She wouldn't let me out of her sight!

So we made a raised bed using some horse manure I picked up with a friend and some firewood. I have great expectations for this bed next year. I expect it will work well enough this year.

I dug a bit of a hole so I had some top soil to cover the wood up with in a later step. I don’t know where my cable wire goes (somewhere in this area) so I didn’t want to go too deep.

We filled the hole with logs and sticks. Leftovers from a fire building demonstration I had done last fall. The tarp has the manure in it.

It’s pretty tall at the moment. It will settle in the next couple of years as the logs decompose.

My assistant was having a blast with this build. She’s inspecting the cart we used to haul the manure tarp from the trailer.

It’s quite hard to tell little helpers that you can play with this dirt and not that dirt. The old manure was a little too green for me to allow for her to eat.

Horse manure goes down over the logs. I am hoping what’s still ‘green’ will work well with the ‘carbon’ of the logs.

Top dressed with the leaves for no other reason than I felt like it.


It's been a while since I've blogged my dinner, but that's because it's…

It's been a while since I've blogged my dinner, but that's because it's not been overly unusual.

This evening I had pulled some carrots that I had planted last spring. They where just pencils last fall, so I didn't mess with them. Look at them now!

So I wanted something carroty for dinner.

So I tried some whiskey glazed carrots. which where very good!

I also made some sort of carrot bread. It's in Danish, and Google Translate made a passable go of it for me. I kinda winged it as I know what bread is supposed to be like.

It actually turned out pretty good. Not to-die-for-great, but good.

I'd make it again. All of it!

Fresh picked carrots that over-wintered in my garden wand where starting to come back up again.

Carrot spinach bread dough. I think… It was pretty wet and the mixer didn’t want to bring it together with the dough hook.

The carrots where awesome!

If it’s on a square plate, it’s a square meal, right? I pan-cooked a bun just to try it and because I was too impatient to wait for the oven.

Anybody know how to delete a photo once it’s in a post?

Dough balls.

Raised buns.

Cooling on the rack.

Hmm. butter. So good!


RepRapped Soda Bottle Cutter

A week or so ago, I designed a Soda Bottle SIP irrigation block to keep all my planters watered automatically. Now all I needed was a bunch of soda bottles cut to make the planters.

I tried a knife resting on a stack of books, and that worked pretty well, but not great. I ended up with an uneven edge on the cut edge.

So I designed and made a cutter!

This was a serious learning project for me. The first one I designed I got my diameter and radius confused, so I had something that was 8 inches across! The 2nd design came together much quicker.

It than took me 3 tries to get it printed!

The first try my filament roll got caught and the printer picked itself right up off of the table! It then stripped the plastic at the extruder gear and let itself back down.

The second try, the part popped off the build bed about 1/4 of the way through the print and made quite a birds nest before I caught this issue and stopped the print.

The 3rd print was a success! But just barely.

I am quite happy with how it cuts bottles. I could have just grabbed a scrap of wood and cut it off at the right height and screwed the blade on and been done in 4 minutes. Instead, I wanted to do the 4 hour print with 4 days of prep.

Print Details:
Designed in Google Sketchup
Printed on a MG Prusa
Slicer 7.1 /Pronterface .7?
.2mm layer height on 3mm natutal ABS with a .35mm nozzle
90 degree Celsius HBP for the successful print.

This is the 2nd try. Getting so much further than the first print.

DOH! The part popped off the bed and kept trying to print a couple of layers before I had checked on it. Upped the bed temp 10 degrees and time to try again.

This is some serious overhang! It nearly wasn’t printable. I had to pause the print and push that edge down and let it cool flat a couple of times.

I was confused as to why netfabb had said 4 meshes when I was only expecting 2. Because some interior geometry was being printed that I wasn’t intending.

The part is looking pretty good, and it’s getting pretty tall…

The cutter cutting a bottle.

It produces a nice, level cut.

The top of the bottle gets shoved back into the bottom like this.
