Early days so cant comment if I am staying with it, but I have just started using this:
Just a usb cable to the computer and then using manufactures software to save the mapped buttons to gSenders keyboard short cuts.
Three dials in the right are used for each axis, large top wheel for z, lower left for x and lower right for y. Set up that counterclockwise turns of the dials moves machine down-left-front and clockwise turn moves up-right-back.
Still figuring out the most used things to have in the six square buttons, but one of them is set up to toggle between two speeds. The speed sets the “interval” of distance so one “click” of the dial moves that one interval of distance, rotating the dial fast does a continuous jog. The dials do have small indents so it is easy to feel the one click when rotating.
The three round buttons at the bottom allow user to switch to the next “page” where all the buttons and dials can have a new function, if wanted.
