Macpronterface connection to CR-10S issue

[JiangXu123]

Hello, I found a weird problem about the connection between Macpronterface and CR-10S Each time, the connection was succesfuly, but I could only successfully sent the first command to the CR-10S, such as setting the bed temperature to 60 degree centigrade, which would take effect but was followed by an error message. The other command I sent thereafter(such as setting the nozzle to 185 degree centigrade) would bring error messages and would not take effect. below is the log:

Any suggestions?

This could be due to non latin characters send from the printer to pronterface. You can try connecting with pronsole, set the hotend temperature and paste the pronsole session here.

Hi @JiangXu123, were you able to stablish the source for the error? If so, could you please share the community what it was and then, if appropriate, close this issue? It did look, as @volconst suggested, like non UTF-8 characters were being sent.
