I can finally configure and use my rotary axis independently. I installed 6 steppers in the box to have one in reserve. With this new version the improvements are significant and the Wifi with its new module and external antenna is very efficient. With FluidNC I no longer need to change the sockets and change the original parameters of the machine each time I want to switch my configuration, everything remains configured and usable on demand. Thank you Bart for this wonderful Open Source concept which is very painful for manufacturers. Best regards.
