Most of the ThorLabs stages (tip-tilt, rotation, ect.) we have are part of the APT family and use the same communications protocol. An overview of the protocol and commands can be found here (Rev 25, accessed Aug 2021). A package apt_control exists for the control of these stages, unfortunately, we have had to hard-code a number of parameters so each stage has its own dedicated version (this is partly laziness and could be fixed in the future). Switching between commands for DC stages, if applicable, and updating the distance/velocity conversion factors may be all you need to get it working for your stage, getting sensible responses from get_info is a good start. Current working versions:
