It’s online and ready for testing.  I would appreciate the help of any beta testers.  Here’s what you need to play:

• A Thing-O-Matic with a MK6 Stepstruder
• Ideally you have filament in 1.75mm and 3mm diameters and in both ABS and PLA
• A fair amount of patience, a willingness to print off some test objects with a variety of profiles, and the ability to summarize your findings for me

To entice you, here’s what v3.0 can do right now:

• Provide good settings for your Thing-O-Matic MK6 Stepstruder for ABS or PLA in 1.75mm or 3mm diameters running a Heated Build Platform or Automated Build Platform
• Allow you to specify the gear diameter, gear swell, and feed rate
• Allow you to generate a full profile based on any stock Thing-O-Matic profile – along with the solidity/fill ratio
• E-mail you the finished profile as a zip file

I’m still struggling with the math required for a DC motor extruder.  However, as soon as I get that sorted out, I look forward to updating this web app to provide Cupcake and Thing-O-Matic MK5 DC motor calculations and profiles as well.

So!  Do you have what it takes?
