[LinuxCNC/linuxcnc Issue#293] Hit remote-EStop while path loading freezes Axis after load is completed About GRBL HAL

Issue #293 | 状态: 已关闭 | 作者: TurBoss | 创建时间: 2017-06-27

Here are the steps I follow to reproduce the issue:

1. Load a big program
2. Hit the remote EStop while still loading

This is what I expected to happen:

nothing

This is what happened instead:

after the path is fully loaded axis goes to a frezzed state

Information about my hardware and software:

* I am using Debian GNU/Linux 7.11 (wheezy)
* I am using Linux cnc28 3.4-9-rtai-686-pae #1 SMP PREEMPT Debian 3.4.55-4linuxcnc i686 GNU/Linux
* I am running A binary I built myself 2.8.0pre
* I am AXIS GUI

Thanks

Can you give a little more explanation about how you reproduce this problem?

I used sim/axis/axis.ini for testing.

I created a part program that takes several seconds to load:
~~~~
g20 g64 g90
s3400 m3

g0 z1
g0 x2 y0
g1 z-.1 f24

o100 repeat [80000]
g91 g1 @-.0025 ^4.5
o100 endrepeat

g90 g0 z1
m2
~~~~
then I arranged two different sequences in a terminal window to trigger an estop condition:

– via iocontrol
~~~~
sleep .5; halcmd unlinkp iocontrol.0.emc-enable-in; halcmd setp iocontrol.0.emc-enable-in false; sleep .5; halcmd net estop-loop iocontrol.0.emc-enable-in
~~~~

– via halui
~~~~
sleep .5; halcmd setp halui.estop.activate 1; sleep .5; halcmd setp halui.estop.activate 0
~~~~

however, neither sequence left the AXIS process unresponsive once it had finished loading the part program.

will try to reproduce tomorrow

I’m sorry but I’m unable to reproduce this again

so there is no bug

Thanks
