Thanks, Davo.

I added a section about "Maximum number of Nozzles" and extended the speed section now. Is this better?

I checked th Hyrel printers. They are not active because the links all return error pages:

http://www.hyrel3d.com/E3/
http://www.hyrel3d.com/E4/
http://www.hyrel3d.com/E5/

If you like, shoot me an email to hello at productchart dot com and let me know what the correct urls are now. We also research more paramters now, so it might be best if I send you the form to enter the data again.
