VB and the development of wizards / Re: Set Machine Absolute zero in vb ?

« on: December 18, 2008, 12:18:10 AM »

I don't had physical home swich, and no limit swich, at startup I make my machine home with the coded index of my linear scale, I setup the machine position with this encoder, and after startup, In my macropump, I check the difference between linear scale and machine position..... that hold the program if the difference was too big.....

i am interested by your plugin for scan input...

For now My homing with reference work good.... but not like in my dream
I am able to Home with only .25-.75 inch of move, anywhere on my table stroke, I need to scan 2 index on my linear encoder

I use G31 to find my reference mark on my scale,  but g31 use the machine 'software position' , for calcul the position with index, I need perfect encoder position,

after find my position with G31, I return back very slowly ( 0.5 ipm) to be able to find my index with loop in VB, I am able to GetOEMDRO(29) and set variable to calcul, I need to scan 2 index like this,

but I don't catch Index pulse every times, the VB was too slow......

--->I need function similar to G31, but when the Index pulse, save zero of my encoder...

the OEM code 706  turn off mach3 without saving readout, 

Do you know how can I saving my Zeros  before  DOOEMBUTTON (706)

On my milling, I had installed linear scale to verify if my position was ok,  i setup max permissible error(.010) ,   In my macropump, small program verify the difference between machine position and encoder position, if the error is too big, the program was feed hold,  and send message error on error windows... but the position of encoder was not use by mach3, it only verify if the difference was OK....

For My Home, I do not want Use limit swich, I want use the Index pulse in my linear encoder...

my linear encoder had coded Index pulse, It was index pluse at each 10mm, but with little different distance at each index, I am able to calcul the position with only 2 index pulse....

I will like home my machine with this index pulse, with this, I do not need to go at the end of my axis, I can home machine at any position....   (See  http://wwwpdb.heidenhain.com/ansicht/Heidenhain/media/img/571_470-23.pdf  page9)

I am just not able to set Machine Zero with this value, If I Use encoder to DRO, The soft limit does'nt work,

VB and the development of wizards / Set Machine Absolute zero in vb ?

        I want homing my machine with the calculated position of my
 linear encoder, with my linear encoder ( Acurite ), I am able to find my position with
only 20mm mouvement(coded reference mark ), I am able with vb script to know table position ,
but I don't know how write this position in Machine Absolute Position, I want preset value in OEMDRO (83)

-I can set machine Absolute to Zero with SetABSZero(X)   but I need to Set
 numerical value
-I can set this position with G92, but the soft limit work with Absolute....
-Call SetOEMDRO(83,T)  can be good but it does'nt work


 I search function similar to SetABSZero(X) but to enter numeric value of my actual position

Hi
I use mach 3 with touch screen and
I want add Buttons for quit mach 3, like if I push the X on the upper right corner
