That's a bit crap! Might be able to get some compensation from the company?

In my experience, the lack of really low end movement (aka too slow for the ESC to detect the sensorless motor's rotation), is compensated for by the combo of extreme power with extreme braking. I may ...

Nick, this shop overhaul is colossal! My envy levels are somewhere in the stratosphere right now. So nice.

ESC getting hot at minimum throttle could be switching losses? If it's so slow that the fets are barely switching on before the pwm pulse is over then you'll get very poor efficiency for 90% of the cy ...

I have found that no-load brushless testing can sometimes result in alarming heat. Normally in low pole inrunners in my experience. I'm not sure why it is, but the same inrunner(s) that would get pret ...

Do you think the small ridges between layers will make ejecting the mould a pain? Every little imperfection will want to grab the rubber a bit. Probably not an issue if it's soft enough but harder com ...

Let me know how you get on with a custom ballscrew (if you go that route) Nick. I'm on the cusp of a CNC build and feedback on one of the many sellers would be useful!

Rolled ballscrews are dirt cheap straight from China. Something like a 1204 ballscrew and nut could make the core of a really nice, efficient actuator. Many of them already have the ends machined, suc ...

I expect the motor in these things is a generic, 5XX (maybe 540), super boring low power specimen. Simply putting in a power tool grade RS-550 is likely to be a huge upgrade and take minimal effort. O ...

Build an electric one! They're the best type for sure. Razz

Did you happen to get any pics of T3? I managed to not take any at all with the top panel off before it got all scratched up.
