General Mach Discussion / Re: Mach 3, wierd infinite feed rate problem

Contact your solidcam reseller.   they can modify the post processor for you or try a different default one.  Not all machines have supported helical interp.

I did not solve the problem.  I switched the output from the post processor in the gcode generator to disable helical interpolation.    In general, I do one of the two following...  avoid helical moves at all costs, or if necessary, hand code them/post them separately so I can easily test the code before use.

You can't.  If you run into this error, mach will go to an absurdly impossible feed rate, and crash into whatever is in its way or stall

No practical solution I know of.

General Mach Discussion / Re: Laser position sensor and mach 3

Yes, I basically have to control a deformation of a part, so I want to pass an actual measurement back after the machine does some actions that will be used to determine the next set of actions

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

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

General Mach Discussion / Re: Unable to activate custom button with external input

« on: September 30, 2012, 01:25:49 PM »

so I figured out how to do this for my purpose (will upload code when done so others can see).  the activate button was really an attemtp to execute code.  after I realized the need for more robust error handling, I decided to write VB code within the button that will take certain DRO's, do some math, and then waith for a series of external inputs to execute.  so now I have a button that I press, and it stays in its code until the exit chriteria are met.

General Mach Discussion / Unable to activate custom button with external input

« on: September 27, 2012, 02:46:34 PM »

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
Greg

One quick question, how does one actuate the custom button with the external switch?  I see the ability to actuate the OEM codes with a switch but I am not seeing how to configure that for a custom button without an OEM code
