Andy, I am using a 7i43 with 7i33 encoder daughter board and 7i37 IO daughter board. I am using a slightly modified version of the stock 7i43-big.ini configuration for check out purposes. I just add signals to individually test the IO before trying to run the real configuration.
For some reason, I was not able to get the amplifier enable to work off of the 7i33 board, even though it is wired identically (AFAIK) to the machine next to it. For the time being I am using an output off the 7i37, which is working. At any rate, in hm2-servo.hal, under Z [2] Axis the enable reads: net emcmot.02.enable => hm2_[HOSTMOT2](BOARD).0.pwmgen.02.enable I then added a line: net emcmot.02.enable => hm2_7i43.0.gpio.046.out If this line is commented out, I get no error. With it in, I get the TRAM error as soon as I try to do a machine on. Regards, Eric On August 23, 2017 8:11:10 AM EDT, andy pugh <bodge...@gmail.com> wrote: >On 23 August 2017 at 06:43, Eric H.
