Tune Racoon

I’ve always wanted a groove box, but I wanted one done my way. So, here’s my attempt:

tuneracoon

Across the top is a multi-oscillator – currently three generators, sine, saw and square. I think I’m going to drop the sine and have two saws and a square. There’s a standard envelope generator and a filter one, plus an echo effect. I got the filter from here: http://martin-finke.de/blog/articles/audio-plugins-013-filter/. The echo effect I created myself.

I use a seven note system with scale and mode configured – so any notes are in tune. Also the chord sequence at the bottom adjusts the notes accordingly.

Getting back into raytracing again. Had a look at my scene editor – did I write it 17 years ago! o_O

Ran out of filament finally

So I’m on some red filament. Here’s a Portal style thing:

Now it’s getting MUCH better!

…and the Netduino fits… almost!

I think the USB slot needs a little enlarging!

It took about two hours to print. I wasn’t sure how well it would work, but it’s pretty good.

Getting better…

Learning to set Z0 correctly!

Had a go at printing some Y belt clamps. Almost works but one side is too tight to fit the belt.

more test prints

Worked out I hadn’t put a final jumper on the Duet board, so it was drawing power from USB. Once that was done, I plugged in a network cable and can see the printer on my home network.

Getting better at printing. I adjusted the Z height to 1mm above what I measured and things are much better. I also switched on the bed levelling compensation. Now my 20x20x20 cube is correct. My next problem is the print lifting off the bed, it doesn’t seem to stick too well.

Here are some hollow test cubes:

cube prints

The left hand one had too low Z height and no bed compensation – hence the squashed look! The second from the left had the Z height raised by 1mm, but no bed compensation. The last two had the Z height raised and bed compensation, and they do come out as 20x20x20 cubes.

Here are some more test prints:

The flange on the left started lifting off the front left edge, as did both of the other objects. The ring in the center is worst affected.
