Single Plate Frame Kit

I bought my frame from Achatz via eBay. What I got was probably the best packaged kit I've ever seen. Every thing in small ziplock bags, every bag labelled with what's inside and how many. No guessing if you have "M4 Washer Large" or "M4 Washer Small" in your hands.

So in the last two days I've gone from exploded view to a partially built machine.

It's funny to see how many build instructions can be found for the assembly of the frame, but how scarce information is about where to put the end switches (Left-hand side? Right-hand side? Front? Back?) and how to best route the cables. I'll just have to wing it.

And so I added a washer behind the big gear on the Wade Hinged extruder (cold end) to align it better with the small gear on the stepper motor. Wrong. Now the bobbed part of the bolt doesn't align with the filament.
Unfortunately that means I'll have to file a bit of the small gear off to get it closer to the stepper motor.

Mostly assembled. Except the cold end.

Assembled and cold end too

I have a Budaschnozzle, the cavity is for a J-Head hot end, and causes al sort of trouble with a Buda.

The problem when you add another washer to align the gears.
The filament isn't gripped by the hobbed part of the bolt due to misalignment.

Electronics

Right, I'm a bit late with this post. I've already assembled and tested the electronics that I bought from learcnc on eBay. Everything works so far. I didn't receive the cable set, so they're sending that to me. Still waiting for it to arrive.

The glass bed I ordered from them arrived in pieces.
They are sending me a new one, that being their policy. How awesome is that! I'm truly impressed with the service I've gotten from them.

I've tested the electronics, and I'm very happy with it. The Mega 2560 is a Taurino Power version, which should be able to run off 12VDC or 24VDC, but I'm not sure about the polyfuse at 16V. Better not risk it and use 12VDC if possible.

So I've modified a PC power supply. That went rather well. I found this page helpful.

The stepper motors all turn nicely and I've played around with the display. Loading a gcode file to the SD card and starting a print seems to work, although with the hotbed not connected it only waits for the temperature to rise.

I need the cables to finish the hotbed, so I'm back to waiting for parts...

First post

...hello?

Mmmm...

That's funny, thought this was a blog, but it looks like a blank white document...

... oh well, I'll be back later.
