DOBOT Mooz 2+: "Machine Position"ing is disabled


Hello, my touch pad will be delivered in two weeks. Now I try to change “Machine Position” after connecting via USB using “MOOZ Studio 2.3.2-beta”, but it fails. The green indicator regarding power on of MOOZ is on. As for “MOOZ Studio 2.3.2-beta”, I follow instructions on page 24 of MOOZ-2PLUS_User_Guide_V2.0-EN.pdf Unfortunately, clicking on Z+, Z+, Y0, etc. and clicking on buttons “set Work Origin” or “Go To Work Origin” don’t move axes at all. How should I ensure myself that the motor steering is fine? Thanks in advance
