I'm still pondering over replacing my ELS project with a Beaglebone running MachineKit so it can run G-Code but use the keypad and display from my original ELS and duplicate the manual style of operation when needed. The LCD display might well be replaced with a larger HDMI type Cell Phone size di

Quick question. For a mill to move the tool bit from Point A to Point B the software parsing the G Code Xn.nnnYm.mmm determines how fast to accelerate and move each axis so a straight line is drawn between the starting and new end points. Similarly, if an arc is programed the X,Y motion is includ

Also , cui says setting alignment will always align with u , so I presume the logic is standard, a,b,c is to u,v,w so I'm presuming that the a should be + and the b - for this alignment , it's a 4 pole motor so it has 2 mechanical lock points 180 degrees apart , should it matter which one of these

Then it is not a "hexapod" The word means literally "six legs" What he has is a "Steward Platform". These are used as shown for mills but also for airplanes simulators and now at amusement parts for those simulated rides Steward Platforms have six motors and are 6DOF. Hexapods hav 6 legs and e

I am pretty sure Dave's hexapod is a six axis milling setup. Not a walking spider robot. Like this one: https://www.youtube.com/watch?v=G_UmhUjZhNo https://www.youtube.com/watch?v=nebJ59TcYlQ On Sat, Jul 28, 2018 at 4:54 AM Chris Albertson wrote: > What kind of hexapod are you building? I've ha
