Hello,
got to work on spindle control of CNC 3040. It runs on MESA 7i92, controller board is JP-382A. Yesterday I made a PWM signal functional by LinuxCNC on the MESA card and displayed it through pin 17 on oscilloscope. Now am thinking about how to connect that to control the spindle. Any ideas ? Most of the threads here had a spindle board JP-1482, which am missing.
Thx, Krokrs
