package

Hi all, I just dropped a package in the mail containing build kits for two units of the 6 axis load cell prototype:

It should arrive on Thursday. Here's the tracking information:

Short of having a complete prototype to test, @mbaker asked me to send the hardware components so he could demonstrate the potential for a low-cost 6 axis solution. The kits will also allow Chunfei or others to ramp up prototyping on Moog's side. The one thing missing from the kits is the flexure plates, which I haven't yet made (I was redesigning them last time I had cycles). If these are important in the short term, without too much time I could make some flexure plates that don't yet have the correct relative stiffness ratios, but would demonstrate the idea.

@mbaker, please let me know when the package arrives if there is anything else that would be helpful to you.

I also included 8 wireless stepper driver boards that I sent out for. These are built around the DRV8825 and can drive the 3 axis positioning stage that I sent to Moog and Chunfei assembled. See #4 (closed).
