>>Some questions for the list (any & all input greatly appreciated - I've never done this before):
1) Z-axis: I'd like to CNC-enable either the quill or the knee. Currently, I'm leaning toward the knee due to greater travel and less cost/complexity.<<<
The knee is never intended for real active use, it is not fast enough, and are you going to put a ballscrew on it? Find some brackets for the quill
>>3) Home/limit switches: Looks like these got pulled from my machine. I have to say, this is the area I know the least about, so any help here is appreciated.
- Does one run home *and* limit switches for each axis (meaning 6 switches)?
- How exactly (or even generally) are they positioned/set up?
- Can anyone recommend a source/part number for such switches?
- Are home/limit switches easily/well supported by the G-Rex? <<<
You only need 2 switches each for the x and y, 3 for the z[assuming quill, would be 2 if the knee]
You mount the switch such that an actuator hits it for overtravel [emo string] in either direction. the other switch is a trip dog only for homing. Hopefully you controller will have software limits for day to day use
>>5) Monitor: If I can't locate a panel PC, I'd still like to use a touchscreen monitor. I've found a good deal on a 15" one ($300), should I splurge the extra $185 for a 17"? <<
You watching videos on it?
