Good enough reason Thanks Clive

will be included in 2.7.5


Thank you!

I scratched my head the whole evening yesterday with that -- beyond the speed it now sets the FERROR accordingly.
The 'Imperial FERROR' was generating strange moves in pncconf (axis going backwards after a jog move) and also gave 'Joint 0 following error' while homing in LinuxCNC.

I pulled the latest version this morning and it now works as expected.

Note that there is a typo in the comments , it should be 360, not 380 ;)

Also, as I was wondering why the maximum values in the UI didn't change proportionally, I realized they where hard-coded in screen.glade, and by cranking up the values for the metric folks, we get very big ranges in the imperial system.

Shouldn't we set the range dynamically based on the system chosen? -- something like:

(Also instead of maintaining 2 sets of values imperial/metric, we could just extrapolate the metric ones from imperial)

Be reasonable metric defaults?

1500mm/min is still pretty slow, I would put it at least 5000mm/min, or better yet 15000mm/min.
The value can always be reduced in Pncconf below the max but not above and any manual change will be wiped on next run of Pncconf.

380mm/min is probably a nice slow speed for the default value.

Cheers.

Russell.
