In the Preference window, in the Machine pane, at the very bottom there is a setting “Machine Radius” it shows 96.7mm. I suppose that is the dimension used for the movement test. The test is successful every time and it is successful even when I set the Radius to 99.7mm.
According to my tests, the platform radius limit of 85mm could be greater but for some reason it is set smaller in Flux Studio. Why is it set smaller than what the machine can do? Could you change the firmware to access a bigger platform surface for 3D printing? Or at least give us an option to bypass the 170mm diameter limit.
While at it, could you also set the nozzle Temperature limit 5 or 10 C higher, since now we have a metal bottom cover in the print heads? If I remember right, I could print at 135C when I first received my Flux in April 2016.
Flux staff, could you please comment on these issues?
