This board will do some cool things in addition to being a noise suppressor: I'm just now getting around to making a board out of his circuit. One of our team members, Nophead solved this all the way back in October 2007. Unfortunately its also a cheap brushed DC motor that generates noise as it runs. The GM3 motor is our dc motor of choice for our extruders: its small, fairly cheap, and fairly powerful. So, today I'd like to announce a new board that we're sending off a new board to the manufacturers: the GM3 Noise Suppressor. One of the things I'd like to improve upon is communicating whats happening in the project and new developments, even if the are not immediately available yet.

Tomorrow, if I have time, I'll see if Zach's upgrade just below cures some of the problems. The pin assignments are in the OpenOffice spreadsheet here. The comms errors are still too bad to make the extruder go properly, though the temperatures are being measured fine.

I suspect we have some stray interrupts from somewhere (like noise on unconnected pins), and also some code in there that switches off interrupts for too long, and so it loses bytes from the input stream. (Incidentally, the Arduino code doesn't do this for all the pins it uses - maybe it should.)

To the initialisation code, then letting the classes set the pins they actually use as they want. With a bit of messing about I got the axes moving, then - when I put the wires on the pins I'd actually defined in the header file - the zero opto-sensors worked too.īut I got a lot of comms errors.

Getting it to start working was pretty simple - I redefined the pins in for the Single Arduino Snap code, and the RepRap Java software started talking to it straight away. I want to do this so I can play with more than one extruder at once, for support material and so on. I stuck my stripboard Sanguino (red S) on my RepRap machine to see if it would fly. Just submitting them for the Final Cut (thank you Pink Floyd).

The corner bracket parts that Ian reported his clients broke a lot are now cut from 8mm acrylic instead of 4.5mm - and I've included a spare.

The X carriage may be removed without disassembling the carefully-aligned frame.

The Y opto flag can be placed on either side of the X carriage so we remain compatible with Ian's design.

X & Y axes can be fitted with NEMA17 steppers.

The larger 4.5mm chain (either of 2 variants) is used for the Z axis, X and Y can use either 3.3 or 3.5mm ball chain.

Ball-chain is used in place of all belts.

The DIY bearing races have been put in.

This can be moved by the head, allowing the carriage to move the Z platform up and down at

There is now a capstan that can be fitted to the top of one of the Z driver rods.I've made the Z motor bracket so it can use opto sensors and a variety of other gear motors too. The Z motor can be replaced by a GM3-type gear motor and rotary encoder.I have put 2 extruder mechanisms on the sheets so you have something to change.The extruder is now swappable and is compatible with the Darwin swap design (if I've got the measurements right on this one too).No hand-tooling of any of the plastic bits, in fact (if I've got it all right). I've taken the best from both in true Open Source manner, so we have: I've built most bits at least twice, and I have tried to remain compatible with Ian Adkins' lasercut RepRap at BitsFromBytes as well as the original Darwin. The Ponoko-inspired lasercut RepRap is now hopefully in its final iteration.
