DANGER
The laser can heat objects when it is in a focused state, so objects like paper or wood can be burned.
Do not focus the laser on people or animals.
Do not let children play with it alone. The process needs to be monitored when it is running. After the process is completed, please turn off the laser promptly.
Step 5 Click the 
icon of Motor on the Operation Panel to make Dobot M1 in the open-loop state.
