Mach3 and G-Rex / Re: MACH3 and Grex

« on: June 14, 2014, 07:19:42 AM »

I have this device since new, and only until now i decided to use, paid for it $300, and hate to throw it , feel like chucking money
i think also that Mariss got taken for a ride on this one, on the software side, if we look at this controller its features are on par with the so called new devices
dont get me wrong I spend my working days operating very sophisticated CNC machines like the twin spindle Mori-Seiki nl2500 with live tooling....
maybe one day someone with time and brains will write a plugin that will make the g100 work.

Maybe something like this would do.
Tank you Hood;
I will try it tonight when I come back, now I have to drive a Mori-Seiki, with twin chucks and live tooling .great machine.

 ActivateSignal(OutPut2)

Do you have an input to Mach that shows the turret is not clamped?
Hood

i have set up pin 11 as an input , and fitted a limit switch inside the toolchanger that closes when the toolchanger shaft has bottomed, but, Im lost on the VB bit

Hi Hood;
Can you please suggest a line that can be added to the vb script so the program does not start until the signal is given that the Toolchanger has reached the bottom of the location slot? That way if there is any missing steps in the Toolchanger stepper it will not do anything until corrected
Kind regards
Mariano


After some sleep I see you wouldnt actually have to put the move to toolchange pos in each section, just having Code "G53 G0 X* Z*" after the first block would work fine.

Like this

 If GetSelectedTool() = GetCurrentTool() Then
End
 End If
 
Code "G53 G0 X* Z*"
While IsMoving()
Wend
 
 If GetSelectedTool = 1 Then
 ActivateSignal(OutPut2)
 Sleep 500
 Code "G53 G0 A0"
 While IsMoving()
 Wend
 DeActivateSignal(OutPut2)
 End If
 
 
 If GetSelectedTool = 2 Then
 ActivateSignal(OutPut2)
 Sleep 500
 Code "G53 G0 A45"
 While IsMoving()
 Wend
 DeActivateSignal(OutPut2)
 End If

General Mach Discussion / Re: Z probing not working on lset

« on: May 27, 2013, 06:01:33 AM »

Hood; thanks for the prompt answer, the z axis probing works when i command the movement in mdi ( g33 z - .. ) and the axis stop as soon as the probe is touched,
I have to find out how to extract the macro from the screen button, ill keep you posted on this

General Mach Discussion / Z probing not working on lset

« on: May 21, 2013, 06:08:53 AM »

Hi; im in the process of modifying my micro lathe to cnc, everything works ok , except the automatic tool probing,
it works perfectly in x direction , but it does not work in the z direction, the machine works perfectly manually or automatic
so i think that the tool probing macro is the culprit.
can someone please help?
thank you
Mariano

there is still a lot to do, like installing a limit switch in the piston to let the controller know that the lock is fully engaged,
also im intending to fit live tooling to it,(very hard), you see I program at work a Mori-seiki NL2500 with twin spindles and a turret that
has live tooling , and I get carried away easily.lol

the clamping system  of the rotary tool changing system is a pair of rings with a taper dog clutch that is spring loaded when in normal state, the round part on the back of
the changer is a air piston that has a ball at its end , in the toolchanger shaft is another ball bearing  , when the piston is pushed forward by the air if pushes one ball again the other
eliminating spring friction and pushing une half of the dog clutch away from another, in the pic you can see the dog clutch rotating
