I agree with the support. I sent several emails asking questions before buying. They were prompt to answer all questions, sending the manual via email for me to review, etc. Even got direct email from them instead of going through eBay for communication (since they could not send the pdf via eBay).

Keep the updates coming as you progress using it. I downloaded ReplicatorG... First project for me will be this: http://www.thingiverse.com/thing:585501

Thank you!!
