Re: [Emc-users] Has anyone tried to use and RC controller with EMC to run a RC brushless

Hello Dave, the RC protocol is very prinitive and thus very flexible. In order to make more channels possible I use a variable time slot which adds up by ten variable pulses (correctly, pulse pauses from 1 to 2 ms) which contain the channel informations plus a 10 ms sync pulse (can be reduced t

Re: [Emc-users] nothing to do with emc

Hello kqt4at5v (what a name!) this kind of collet is the standard tool holder on my Steinel vertical mill, in size ER40 with a Morse taper 3 shank. Very reliable, just once, with very large cutting force in cast iron, the 12 mm bit got pulled out gradually, digging deeper and deeper. I noticed t

Re: [Emc-users] Wiring Standards

Hello Andy, current supply rings are a fine idea, but only at and above 10 to 20 kV-level. In house wiring the copper size plays almost no role as far as gross cost is concerned (labour vs. material). In my company I was responsible - among other things - for the electric power supply of, on t
