My diy CNC, over 13 years old and finally decided to add homing and limit switches so I could take full advantage of “ScreenSet 2010” screen software.
My System: Mach3, ESS Smoothstepper, C25 BOB, Gecko 540 drivers. Proximity Sensors NPN NC 4mm 6-36V, and ScreenSet 2010 a very nice screen display utility.
Recently built a perforated PCB containing the necessary resistors and Diodes to set the output voltage. All sensors can be activated on and off and light the apporiate Leds on the BOB and in the Mach3 Config screens. I positioned the Proxi switched so they activated a few mm before the axis hit the hard fast limit, in preparation for homing and such.
I could drive all the axis without any issues. I could start the ScreenSet 2010 (SS) and reset as normal no problem.
BUT, I was touching some of the SS homing axis buttons at the top of the screen and after that I received a “Limit Switch Triggered “ error msg. However there were none of the switches triggered. And since that time I cannot get out of that error msg.
Because I didn’t have homing or limit switches before I could not use any of the SS properties such as homing, auto Z Zero or many of the features of SS that I would like to use.
I tried starting up the system without the Proximity system powered up and I still got the same Triggered msg.
Any suggestions?
