          ok, i had to reread your message again to understand what I should do 🙂

          new printing job with added M122 after the echo 10

          G10 P0 S180 ; sets the temperature

                @timschneider thanks, looks like this issue may be specific to SBC mode. I'll ask @chrishamm to take a look.

                    @timschneider Thanks, I've got a bug fix ready for v3.4 and v3.5. I suggest you use conditional G-code only in macro files until a new version is available.

                      Hi @chrishamm , thank you for fixing my issue lightning fast - but unfortunately the problem from @niocio01 must be something else, cause as far as I know, the daemon.g is running in the macro branch and is not related to the job processor. I thought it is related due to the message and the G4 in the daemon.g.

                      Maybe he is hitting some special value?
                      For example

                      var testVar1 = 99E9999999999999999999999

                      will crash the duet RRF. Is there a value which is able to reset, unset a variable?

                        @timschneider thanks for pointing out the bug in RRF when you try to set a variable to that very large value. I will fix it in the 3.5 source code.

                        I suggest you use

                        var testVar1 = null

                        instead.
