Hi Scott.

Firstly I would like to thank you for all the effort you've put into this. It is people like you that allows the idea of a "maker community" to work.

Some questions:

  1. I am struggling to use your Excel Spreadsheet which drives your Inventor parameters. Whenever I try to adjust the build size, I am met with a bunch of broken constraints and sketches. I have also tried to modify the Excel Sheet to reflect what is calculated in the Excel Configurator Sheet, but this also does not update the parts correctly. Could you perhaps upload a commented version as you did with the Configurator Sheet?
  2. I have previously played around with Tech2C's design and was wondering about something. Would it not be possible to move the motors to the outside of the frame and have the belts run on either side of the uprights? This would free up a bit of space on the inside. I have attached an image of what I meant.
