Problem with ESS Mach4 Spurious Limit hit event
« on: August 21, 2017, 03:53:49 PM »
Hi,

I am facing some problems with Mach4 and ESS,

1st- both Mach4 and ESS are last versions, when i try to open ESS Diagnostics window, it pops up and when i move the mouse it locks Mach4 and give some error related with wxwidget..... (u can see the error below) and force Mach4 to shut down,

2nd- when i select home switches as -limits, in -limit hits Mach4 gives "Spurious Limit Hit Event...." error and locks the interface, other than this home switches works fine machine homes itself using home switches just it does not zero the axis DROs, i had to disable the -limits to be able to operate Mach4, also if i assigned +limits as -limits for test, it does not give that error so i am guessing this problem is not because of noise, ( Andy from ESS could not help me about this problem)

3rd- spindle works fine, it turns as commanded, vfd is Delta brand and it provides Spindle at speed and zero speed signals which i mapped to port1 Pin11 and Pin12 and when spindle reaches the entered frequency by gcode "spindle at speed" led lights up in diagnostics and when it stops "zero speed" led(i put it myself) lights up in diagnostics so vfd sends the signals correctly but when operating a gcode in MDI machine does not wait the spindle to come up to speed. So i guess a M3 macro should be written to implement this feature to Mach4. Can u help me in writing this macro to tell to Mach4 in M3 command it should first wait Pin11 to be activated and make sure the pin12 is not active for going on to the rest of the gcode.

Thanks.

I too am having this issue after updating Mach4 (V4.2.0.3233) & the ESS plugin (V206).
Any thoughts on this would be greatly appreciated.

This problem has been discussed in warp9td forum and already fixed. Upgrade your ESS plugin from 206 to latest version.
