The firmware file does exist, I have even used it. But I can't see it in the package downloaded from Mesa or the LinuxCNC firmware package. > the 7i39 board is a good board but is expensive with cost and pin usage > (16 pin used for two motors and 8 pin unused) Arguably the 7i39 is economical on pins. The hostmot2 2-phase PWMgen normally uses 6 pins (one pin for each gate of the inverter bridge). The 7i39 configs only use 3. 3 pins to control the inverter, 3 Hall sensors and 3 encoder lines is the bare minimum required. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Everyone hates slow websites.
