Peter, The firmware file is SVTP6_7I39.BIT.
The excerpt from the ini file is: [HOSTMOT2] DRIVER=hm2_pci BOARD=5i20 CONFIG="firmware=hm2/5i20/SVTP6_7I39.BIT num_encoders=3 num_pwmgens=1 num_3pwmgens=2 num_stepgens=1" [EMC] Right now, if I comment out all the lines in the hal file that touch any of the stepgen or pwmgen pins, the axis gui will start but there are no pins created for the pwmgen or the stepgen. While the correct number of encoders are created, the third (spindle through the 7i33TA) isn't showing any movement when the spindle is turned by hand. >From what I can tell from reading the 5i20/7i39/7i33TA manuals, hal file, and looking at the wiring: P2 on the 5i20 goes to the 7i39 and uses the pinout in the 7i39 manual. This runs the X and Y BLDC servos and uses two of the encoders and the 2 3-phase pwmgens from the config line in the ini. P3 on the 5i20 goes to the 7i33TA and uses the pinout in the 7i33TA manual. This is used for the analog signal to the spindle drive and the spindle encoder and uses the third encoder and the one regular pwmgen from the config line in the ini. If the 5i20 doesn't have enough firmware space for the other 3 pwms and encoders on the 7i33, no worries, I wasn't really planning on using them anyway. P3 on the 5i20 goes to a OPTO22 board. GPIO pins 48 and 49 are used for step and direction from the stepgen. In the HAL file, they get set to open drain and inverted but no other connections are made. Physically those two pins go to the setp/dir pins on the Gecko drive that runs the Z-axis. The remaining GPIO pins, 50 -71, are just used for regular field I/O (limit switches, relays, solenoids, etc.). -Chris On Sat, Jan 30, 2016 at 10:04 AM, Peter C.
