New Arrivals

30 01 2009

Got a bunch of gear in the mail this week:

laser safety goggles, tuned to the 808nm infrared of the cutting laser. Here is the spec sheet. These are model EP-5, so they have OD3. OD5 is ideal for the power range we are working in, but OD3 is INSUFFICIENT  better than nothing. To be on the safe side, I plan to only operate the power lasers in an opaque enclosure.

Tiny Tiny beam splitter. 

img_3146An finally the new geared motor for the new pinch pulley extruder, with the perfect timing belt pulley on it’s end.

Coming Soon

I took a page from zach’s design, for the latest hercules extruder:



This ended up not working very well. Not enough torque or grip overall. I just purchased this geared motor. Zach mentioned having issues actually getting his hands on the Kysan motor his design uses. I’m impatient, so I’m going to design around another motor, BUT try and follow Zach’s design as closely as possible otherwise.

Another Iteration

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

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.
