Hi there,
I truly understand your pain. I bought my 3D printer about two years ago and it took me a while to get the printer up and running smoothly (although I still have to troubleshoot here and there still). Having worked through all of the issues with my 3D printer I have become somewhat of an expert with it, and I can help you and your son out. I am a mechanical engineering student from The University of Texas at Dallas, specializing in robotics and automation. I actually am working on a STEM educational startup, that I started with a few of my engineering friends, where our mission is to empower kids to become creators of technology rather than just become passive consumers of technology. I could tell you more about it and would love for your kids to try out some of our projects since we are currently testing our projects out with kids to see how we can improve. Thank you, I look forward to working with you soon.
Best regards,
Phyo P. Sone
