Hi there, a sample config with steppers connected to a 7i43 is included with emc2. Look at hm2-stepper/7i43.ini. Poke in your stepper timing parameters and give it a whirl! > My machine has a short write up on wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Pjm - > the 7i43 should enable much better spindle encoder speeds to be read, there > by > improving the closed loop spindle speed control etc. That should work. The hm2-stepper sample config does not include an encoder counter, but it's easy to add, just change the [HOSTMOT2]CONFIG field to include "num_encoders=1". If you're using step&dir to control the spindle, then add another stepgen output by changing the current "num_stepgens=3" to "num_stepgens=4". Look in the dmesg to see which of the 7i43's pins have what signals. There should be plenty of I/O left over for your limit switches and pendant if you want to move that to the 7i43 too. -- Sebastian Kuzminsky ------------------------------------------------------------------------------ Come build with us!
