General Mach Discussion / Re: Can Mach 3 do this ????
« on: March 14, 2013, 10:24:26 AM »
Les, I understand what your saying about replaceing screws and an operator being able to take out backlash but on a cnc backlash is a huge no no to get the benefits of cnc.  The difference between the operator and any control driveing the machine is timeing.  I havent seen any manual operators be able to interpet a 3 inch circle with a 1/2 inch cutter at 30 IPM.  Nor have I seen any controller be able to take any amount of backlash out at any speed and still get flawless results.  Maybe acceptable, but never flawless.  The big question is how right does it have to be for you?  Backlash will cause you a lot of grief and should be prioriety one I think.

I'm partial to servos myself but I have a Bridgeport clone running steppers.  It will never miss a step unless I ask it to do something it simply can not.  If I had any intentions of putting an operator (button smasher) in front of the machine I would consider Servos a must.

I had Rockford Ball Screw make my scews.  A Bridgeport kit wouldnt work in my knockoff.  :(  I think McMaaster Carr had a bridgeport ballscrew kit.  Google will find you lots of options most likely.

Advise, drive the quill for the z rather than the knee.  I did my knee and its painfuly slow.  I will keep it for tool height comp. and drive the quill for the z at some point.

Hey Les, welcome to the forum.

Mach is not closed loop.  you can feed positional data back to Mach and have it monitor the desired/actul position with allowance and have mach throw a fault if it gets out too far.  You can run servos with Mach.  Some hardware will allow you to run analog input drives (CS labs), others will only allow step and direction (smoothstepper).  I think most that do what your wanting is let the drives keep track of the position feed back and set the drive to send a fault signal to Mach if it gets out more than their following error will allow.

I'm not sure, been a while since I messed with VB but that use to be a global setting.  It's easy enough to test though.  Put 2500 in a macro and run it, tick the box and run it again and see if it affects the timing.  It's probably documented in the manual.

I'm not sure how they do the blended feed rates.  I'm only guessing if the blended FR is different than the programed FR in a single axis move it is because that move has been adjusted in preperation for another.

You have an option in general config to set the G04 dwell to miliseconds.  If it isnt ticked it will be in seconds.  This is true for the parallel port.  If your useing a Smoothstepper, I think all timeing is in seconds but let someone else confirm this.

Yes, 2500 miliseconds = 2.5 seconds.

Well, you have to make sure it is the right mode to be able to use the MPG.  MPG only works in mpg mode.

Hit the tab key and the mpg flyout will appear.  There you will set which axis and what mode.  I would set it to single step mode and jog mode to mpg.

You can set soft limits without home or limit switches, just better if you have a home switch because that is what the work off of.  Do you have a certain spot you always jog the z to when you refrence the machine?

Do you have a home switch on your Z axis?

I have a motion card in CNC Router

What kind of motion card is in the router?
