Re: Fan connections... variable speed fan not working
There is no way to control a BLDC motor with the PWM found in RepRap-style firmware. Use 100% all the time and be done with it. I've been thinking about hacking together a proper 12V supply + pins to make it possible to use actual PWM controlled fans. 2A DC-DC converter for $15, teeny perf board fo...

PETG is good stuff, but if you don't want to needlessly buy a roll, you might test your glue on some straight PET first. Most soft drink bottles are PETE (#1 in the little recycle triangle), which should be pretty similar to PETG as far as glue is concerned. Polystyrene (PS #6) should be similar to ...

Re: Collaboration Opportunity with MakerGear
So it's a weird first post, but I've been running/upgrading a kit-M2 for a school robotics team for a couple years, and lurking the forum for about that long, so.. Automation engineer with C# skills (mostly for HMIs), plus various experience in machining and electronics necessary to get said machine...
