Relief cnc cutting

Here’s a neat relief cutting I did for a client.

Grand rep rap bot

Well the 3rd generation of my 3d printers is now operational. I’m sure there will be some initial growing pains but so far the Wilson is shaping up to be a wonderful machine. The newly acquired smoothie board is fully operational and I even managed to print a calibration pyramid with the arcol v4 all metal hotend I picked up a couple years back. I still have to wire up some end stop switches and tidy the wiring. All the components I received from Voxel Factory were top notch. The power supply barley turns the van on even with the mk2a aluminum heated. Although our miserable weather might have some input.

More finished projects

Here’s a couple other projects I’ve done recently,

Some essential oil display units.

This is how I cut them.

And some posts for a stairway.

CNC Shenanigans

At work in part of the ongoing rebuild of the shop I put together a kit CNC that’s been performing wonderfully but recently one of the g201x Gecko motor controllers stopped working. After verifying it wasn’t either the motor/wiring/or controller channel, if the non-existent green power light wasn’t the dead giveaway, I sent it back to gecko for hopefully warranty. After doing a little more research I discovered the g201x don’t have any protection circuitry and the 20% more expensive ones, the g203v, had not only loads of protection circuitry but an internal fuse too. I ordered up two as they were pin compatible with the g201X, or so it said. After receiving the motors I had a good chuckle that even in the manual they referred to how indestructible the G203V ones were. Saying the V in the name was for vampire.
It turns out though by pin compatible they mean all but one pin which has an opposite select voltage, 0V instead of 5V for the motor disable, or was that the other way, needless to say it
Tripped me up for a bit. After a few helpful emails from Ahren at CNCrouter parts, my kit supplier, I learned that to mix these two “pin compatible” drivers I would need to wire up one of the drivers manually instead of using the nice pre-done wiring. Eventually I got it working and after fiddling with the trim pot on the motor driver all was back to normality, whatever that may be. It was nice to be back cutting again. I think I’m going to change the whole machine to the new drivers as there relatively inexpensive compared to down time and hopefully with the warranty I’ll have two complete sets letting me use the nice wiring board. Plus I think I already have another plan for the other drivers, laser cutter/engraver.

Luxo Lamp

I love this Luxo Jr. Lamp. I printed one up and put a blinkm light in it. I’m hopefully going to get some printed for my nieces for Christmas.

Prusa v2 update

I just finished my third printer, the makerbot is now a grandparent. Behold the prusa v2.

20121209-185700.jpg

I finally got around to putting on the old v1 heatbed and I hooked up the arcol v4 resistor. Sadly the stainless steel thing is far to fragile and blew out, I’m also dissapointed it uses a different thread size then the standard heater barrel, so I can reuse the awesome resistor core and mount, so i’ve thrown in a Maker Gear heatcore with a .25 big head nozzle. So far so good.

This build also has machined pulleys and t2 belts with lm8uu linear bearings. Finally I get flat bottom layers and circles are circles.

I’m also digging slic3rs new concentric fill, still a few bugs in the way it sorts stuff but I’m sure it’ll get fixed soon. Thanks sound for a great utility. I haven’t gone back to skeinforge since it tried it,

Hall effect home switches

Here’s some home switches for a cnc or 3d printer, opensource hall effect switch

update:

I built a bunch of these and have since installed them on the cnc at work and on my new prusa v2 reprap build. There great, I love the versatility of using the magnet as the switch, i’m able to tape or glue or if there’s some metal frame nearby just stick it to it. Plus the little light to let you know its on is nice. Mine are uv LEDs. I almost wonder why people still use the optical endstops, they definitely cost more.

In that picture you can see the y and the z the little magnet for y is on the bottom bolt on the heatbed, I havn’t quite figured out how to mount the z or x one yet, yeah g92 x0y0z0.
