General Mach Discussion / Laser position sensor and mach 3
« on: February 28, 2014, 12:44:25 PM »
All, I have an interesting problem.    I have a machine that needs to take an input from a as yet unspecified laser position sensor and use that value as feedback to control other motions in the machine.  I can see immediately how to implement all of that into mach except the laser position sensor.   

Has anyone coupled mach with a laser or other non-contact position sensor?  I had thought about the touch probe option but the part I need to read is so flexible that the touch probe could easily deform it.

thanks
Greg

General Mach Discussion / Analog inputs to mach 3
« on: June 17, 2013, 12:00:21 PM »
So I have a need to get a couple of analog sensors talking with mach 3.   I do not see a direct way to interface an analog sensor with mach 3 (appears to be all digital on the inputs).  Can anyone suggest a good method for interfacing?

thanks

Alright, I need some help here.   I have created a custom button in the screen with a hotkey of ctrl+g.  I have set the hotkey of input #1 to ctrl+g    input 1 does not, however, activate the custom button,  ctrl+g on the keyboard does work to actuate the button.

Now if I reconfigure input 1 as an oem input and link it to an oem code the input works

the diagnostic screen shows that the input does change when the eternal switch is activated.

can someone please help me figure out how to get an external input to activate a custom button in mach?

thanks

General Mach Discussion / Code execution and input signals question
« on: August 30, 2012, 05:56:47 PM »
Alright folks, let me detail below what I want to do.  I have part of it figured out but I have not been able to figure out how to do all of the moves without loading a new file manually and how to count and display.

Here is what I want to do.  I have three input switches:   

I want the first switch to execute a section of gcode each time the button is pressed.  I would also like to count the number of times this switch is pressed and display that count.

I want the second switch to execute a different section of gcode and reset the counter for the first switch.

I want the third switch to execute yet another different section of code.


what I am working on is a tool for punching a material and inserting the punched portions into a set of tubes.   the three motions mentioned before control some critical parameters of the process.  I have not figured out how to do all of the above without manually loading different code at certain times, and I would preferr to automate the process more.

any help is appreciated,
thanks
Greg

General Mach Discussion / Mach 3, wierd infinite feed rate problem
« on: June 27, 2010, 03:55:57 PM »
Something goes horribly wrong in mach 3 mill when I run this code:    At the bold line, it tries to make the Z move instantaneously.  you can hear the stepper motor stall and watch the z value change instantly (even when setting the feed override to 10%) on the readout.    I suspect something is wrong with the code that is confusing mach, but I also consider it a safety issue if mach can suddenly decide to ignore the motor tuning settings due to some quirk of gcode.

the mach version is: 3.039.  If it has been fixed in a later version, then it will be worth the trouble to upgrade.  Any ideas folks?
