PoKeys / mpg and pokeys plugin

« on: December 27, 2009, 04:57:04 PM »

i have the latest pokeys plugin installed. have upgraded the firmware to the latest from poscope.i have fast encoders enabled. when checking raw encoder output in the pokeys software , i get good fast encoder response. when mach3 is started, checking io of the pokeys, sometimes shows output , sometimes not. i have the mpg enabled in ports and pins, port 10 pin 1 for a, port 10 pin2 for b.
in the pokeys plugin config, encoder1 is set as mpg4.am i supposed to have a brain running for this to work? is the modio brain need to be enabled?

General Mach Discussion / lathe index led intermittant .

« on: December 02, 2009, 02:34:53 PM »

is the index led supposed to blink on off all the time when the spindle is turning? i have it flashing on about 5-6 times , then going off, then randomly lighting. i have rpm readings from 100-3000 rpm. my spindle motor is driven by ab impact vfd, takes step pulse for speed. i can enter into the spindle speed 1345 and the spindle rpm is being read by the spindle sensor as 1345 +- 1rpm so i know that the spindle sensor is working properly. this is by 2 parralel ports, cnc4pc bboards, and cnc4pc index pulse board.

i have tried reinstalling the latest version , still the same. tried using smoothstepper, still the same. reason i am concerned the index is not working properly in mach, and have been having problems threading.

PoKeys / setting up input for oemcode

« on: November 25, 2009, 02:06:30 PM »

i am trying to set up the pokeys to do the following.i have two momentary buttons along side of an mpg. one button i wish to select the x axis, the other select the z axis.
i have set up oemtrigger 1 to be oemcode 59 for the x axis. oemtrigger2 is oemcode61 for the z axis. i have in ports and pins, oemtrigger1 port 10  pin1. oemtrigger2 port 10
pin2. how is the pokeys setup for this? i see in the pokeys software to set pin 1 as an input, pin2 as an input, but what after that? as a macro? keyboard shortcut? i am confused.

General Mach Discussion / dro at startup

« on: October 08, 2009, 07:43:48 AM »

i am setting up mach3 for use as a back gauge for a pressbrake. when starting up, the x axis dro does not display the last position that it  was at closing of mach. is there  something in configuration settings that needs to be checked, or must i save as a tool offset, and being up in the initialization string?

VB and the development of wizards / turret tool macro

« on: June 24, 2009, 09:22:06 AM »

hi all. i am having difficulty getting a toolchanger macro to work. here is how it has to function.jog the x and z axis to a safe position,activate output19 which switches on an air solenoid, jog a axis to a set position 45,deactivate output 19, activate output 20, deacivate output 20.
here is my macro.

DeActivateSignal(Output20)  " make sure solenoid is realeased.


code"z1x3"                          " jog to safe place for toolchange
While IsMoving ()
Wend
ActivateSignal(Output19)    " turn on solenoid to raise turret
code"g4p1"                        " wait 1 second
code"g0a45"                      " rotate turret
While Ismoving ()
Wend

DeActivateSignal(Output19)   "release solenoid
code"g4p1"

ActivateSignal(Output20)      " turn on solenoid to retract turret

code"g4p1"



 
DeactivateSignal(Output20)    " release solenoid


code"g4p1"                          " wait 1 second

the code skips over the deactivate signal. if i run the outputs individually in mdi, they work . pushing reset deacivates.

the machine is a hardinge chnc3. the turret is driven by stepper motor.

General Mach Discussion / variable frequency spindle drive step and direction

« on: February 21, 2009, 04:19:44 PM »

hi all. i have an allan bradley 1336 impact variable frequency drive for the spindle on a hardinge chnc4 retrofit. the vfd has the ability to be driven with a step pulse. i have it connected with mach pin 8 outputting to the drive.index pulse is thru slotted disc on motor pulley.
the drive has  feedback from the existing heindehain 1024 encoder  . all i can say is wow! ask for 1589 rpm, get 1589 rpm. enter 472,
get 472.
after reading about others and there trials of getting the analogue set up, i was looking to that part of the retrofit with trepidation.up and running in 1/2 hour.

anyone else using step pulse with a vfd?

General Mach Discussion / optical switch for lathe index

« on: November 29, 2008, 03:33:29 PM »

i am in the middle of a retrofit of a hardinge chnc4 lathe.moving right along,x and z axis have e6d us digital encoders installed with gecko 320s.ab 1336 impact vfd  with 7.5 hp motor.reading of others and their trials and tribulations with the tool turret, controlled it  by geared head stepper motor with gecko 201  and a 5way solenoid air valve.   can anyone recommend an optical switch for the lathe index pulse? i cant mount a slotted disc so it has to be reflective.  thanks

VB and the development of wizards / jog z manually during macro

« on: August 25, 2008, 09:50:47 AM »

hi all.
i am trying to create a macro  for jogging the z during a macro. i want the z to be able to jog manually first, then from input 4 , resume the macro.

i have tried this,

code" g0z1"     'jogs the z to a safe height
while ismoving()
wend
 
'this is when i want to jog the z manually
code "g92z0" ' zero the z axis


SystemWaitFor(INPUT4) 'wait for a push button input

ActivateSignal(OUTPUT1) ' turn on relay 1
code"g4p1" 'pause for 1 second

the macro does not pause.

what am i doing wrong?
thanks
