      @lahn92 If you are able to edit config files on the Pi, please try to change SpiPollDelay from 25 to 1 in /opt/dsf/conf/config.json and then restart DCS via sudo systemctl restart duetcontrolserver. This should reduce the response time before the BLTouch pin is deployed/retracted, but it will increase the CPU load on the Pi a bit. Please let me know if that fixes your problem.

        made the changes you suggested, and it is getting it to a working state. there still seem to be a noticeable delay that changes from probe to probe. but none of them are long enough to error out the BLtouch.

        so its working, but not sure if it behaving as intended. but maybe as good as it gonna get on a pretty unusual config.
