Some commands you can try are "M+500" (start with speed 500), "H0" (set origin [0] to current pos), "R1000" (index to 1000), "@" (software reset)
You can ask Kaidan for more info on the available commands or even on the serial protocol used (will try to put a PDF of them with all the commands here, have to ask for some permit from Kaidan first)
