Hi I am a relative newcomer to the world of CNC Mills and am in the process of building my first machine. I have searched high and low and have seen a few other posts with this problems and have tried their solutions all to no avail. I have everything running with the exception of full spindle control. I have a Huanyang 2.2KW spindle with the Gecko 540 running to Mach3. I have set up a relay to short the FOR and COM circuit to start and stop the spindle and that works perfectly, however the speed control is not functioning. I have taken the 10v, Vi, and ACM pins and run them to the 7, 8 and 9 pins on the Gecko respectively. My Mach setup is shown in the photos attached. Sorry for the lack of cable color, i was running low XD.
I have set the Pd001 and Pd002 each to a value of 1 as well. With this setup the spindle will turn on but will only go full speed or no speed, indicating none or all signal going to the Vi pin. I have also set the Pd070 value to 0 indicating a 0-10v range and Pd073 to 400.00 for the full range. I have also tried ranging the output PWM frequency from 0-400 in the spindle options in Mach3. I am at a loss at this point, any help would be greatly appreciated, thank you!
