[LinuxCNC/linuxcnc Issue#180] python interface About GRBL HAL

Issue #180 | 状态: 已关闭 | 作者: MZot | 创建时间: 2016-10-16

1. When in MDI mode, linuxcnc.stat.settings[1] (Feed value) returns wrong value if in G95 mode after spindle is started:

-Issue G95 in MDI
-set feed with F word
–go to jog mode and back to MDI
-turn on spindle with M3 S

This is what I expected to happen:

1. linuxcnc.stat.settings[1] should return the value that was set with F word

This is what happened instead:

1. linuxcnc.stat.settings[1] returns value, that is 60 times greater than value that was set with F.

It worked properly before this:

I can replicate this problem with LinuxCNC 2.7.7.

I started sim/axis/axis, F1 F2 Ctrl-Home, switch to the MDI tab, G21, G95,
F10 (10 mm/rev).

Then in another window I ran python, imported the linuxcnc module, instantiated linuxcnc.stat, polled, and got settings = (0.0, 10.0, 0.0). Back in Axis I switched to the Manual tab, jogged around a little, switched back to MDI and ran ‘S1000 M3’. Back in python i polled linuxcnc.stat again and got settings = (0.0, 600.0, 1000.0). In Axis MDI tab, the ‘Active G-Codes’ also shows F600.

Another data point: same version of linuxcnc, same (imperial) config, F1 F2 Ctrl-Home, no G21, G95, F10, jog around, then S100 makes the Active G-Codes F-word and linuxcnc.stat.settings[1] jump to an unexpected value.

There are two bugs here. One is that the F-word changes surprisingly, and the other is that you have to issue an MDI command (after Aborting, or switching into and back out of Manual) before the wonky F-word is revealed.
