Just to be honest ,
i did a lot of tests and even tried to add menu points for spindle and laser what ended up in unusability.
Why?
most , not to say all parameters you want to change for spindle and laser have to be changed on the fly,
so you don´t have the time to scroll in menus.
As i don´t know what type of machine you use as mill just imagine what happens when you have powerful
components (i use a 2.2kW Spindle on my mill and believe me it´s not funny standing next to it when a 12mm flute breaks apart because of not reacting fast enough)
Thats why i use a simple potentiometer for controlling speed and switching on / off respectively direction is controlled
by g-code and buttons.
similar situation for Lasers .
But that´s only my personal point of view.
nevertheless for shure I´m interested in new features , may be they change my mind ;-)
