Regarads this package: I have asked the seller for a manual explaining how to dowload the g-code! In general buying this CNC stuff is a nightmare. Quality UK (or .EU) stuff is VERY expensive (like over £100 for a 300 Ncm stepper and its driver board - Multiply by 3 and WTF?) 500 mm C7 ballscrew? [adopt Monty Python Accent] "Ballscrews Sir, You should see ours, They are the absolute best, Wink, Wink, Nudge Nudge . Buy these and its as good as a nod to dead donkey! 500 mm ball screaws and nuts for £100 plus?? For the real link: https://www.youtube.com/watch?v=AGrvQ1c5khU&list=RDAGrvQ1c5khU#t=16 |

I can't speak as to the quality of the product, since I've never actually purchased anything from him, but a German member of a local forum is very highly regarded for the quality of his controllers. Among those who know, he is considered on par with Gecko. Benezan-Electronics.de |

The Chinese have had closed look steppers out for months now and even their Servo motor / driver combinations are very, very competitive. You can get a 1.8Kw servo motor and driver which would make an ace spindle motor on something like a X3 or WM16 for £280 |

Sorry if this is a rather stupid question. Is the loop closed between the servo motor and driver or does it pass through the machine controller? Can a closed loop servo system be used as a spindle motor on a lathe to enable basic thread cutting function with a controller that does not accept encoder feedback? |
