I know Gunther has listed a few Motion Control systems which support 'slave mode' does anyone have any experience of additional models which work with the LTRPT ? I'm interested in the Edelkrone system and I have seen in the forum that this did not support slave mode back in 2019. I have e-mailed them too.

The ones Gunther listed are :
Emotimo devices (including Spectrum)
NMX from Dynamic Perception
Pine Controller from Black Forest Motion
