Thanks Peter. I am sorry, I maint PMD, not PID in my statements above. I tried to calibrate running HAL, but the analogue output is being clipped at 1 V. There is probably a setting such as MAX_OUTPUT that I have not set yet. The OUTPUT_SCALE and OUTPUT_OFFSET settings in the .ini file is

I have managed pretty well converting 3 machines to EMC2 - two using the parallel port and one using Mesa 5i20 and 7i29 cards. However, now I am looking at using a 5i20+7i33 setup to drive analogue servo drivers that need two inputs, AN+ and AN- 10V (and GND?). It is not clear to me how this is to
