Reprap Frustrations

19 01 2009

I’m having a tough time getting the Gcode firmware to work on either the Arduino or the Sanguino. The PDE files compile and upload properly, but when I issue a Gcode command through the serial connection, such as “G1 X10”:  it does not work, and I get this crazy response:

Another Iteration

17 01 2009

I still need another iteration in the design, but getting close:

Now we have a lighter nema 17 motor, and better balanced on the x carriage:img_3079





More Hercules Extruder activity.

Zach is doing R&D on the Hercules Extruder





Danger Laser

15 01 2009

I just received a Coherent 808nm Laser Diode 3.5V 60-90Amp 50-60W:

Freaking awesome. High power cutting laser. I’ve always wanted one of these.  This is powerful enough to cut just about anything except metal. 

I’m going to turn this into a cutting head for the reprap.

You can see the electrical power connects, and the water cooling connectors.

 

This laser is dangerous:

THERE ARE NO “OOPS THAT WAS BRIGHT” SECOND CHANCES WITH THIS LASER! A single careless glance into the beam or it’s reflection WILL PERMANENTLY BLIND YOU FOREVER! To the eye the scattered output looks as bright as a red laser pointer, but that same “weak looking” beam will light a piece of cardboard on fire in about 1/4 of a second!

Protective eyewear is mandatory. I’ll provide a full safety rundown prior to firing it for the first time. 




Hercules Extruder Redesign

15 01 2009

I did a from scratch redesign of the hercules extruder  now using the nema17, mounted above the x carriage for best balance. Looks like this:

Hercules Extruder for real

Very happy to have this hercules extruder  sitting on my desk.  Shout out to Max Steiner for time on his machine.

Nothing fit correctly! I had to file down just about every surface, but it’s very close. I need to add wiggle room for all of the holes.

Here it is installed.

It’s quite heavy, and puts significant torque on the x-carriage.
