[LinuxCNC/linuxcnc Issue#269] G-Code error when attempting to touchoff. About GRBL HAL

Issue #269 | 状态: 已关闭 | 作者: phillc54 | 创建时间: 2017-05-15

## Here are the steps I follow to reproduce the issue:
1. run axis sim
2. E-Stop off
3. Power on
4. press Home All
5. press Touch Off
6. press OK

## This is what I expected to happen:
Zero X axis in G54 coordinate system

## This is what happened instead:
The following error message:
G-Code error in axis.ngc
Near line 0 of
/home/phill/blah/blah/blah/axis.ngc:
Line with G10 does not have L1, L10, L11, L2, L20

## Information about my hardware and software:
* Debian 7.11 (wheezy) in a VMware Fusion virtual machine:
* 3.4-9-rtai-686-pae #1 SMP PREEMPT Debian 3.4.55-4linuxcnc
* v2.8.0-pre1-3125-gd63aca6 as a rip build
* AXIS gui
* sim configs only – axis, lathe, historical_lathe, gantry, ldelta and rdelta all behave the same

Issue first appears in commit 001eb00, last working commit was 596363b.

I confirm this happens on the tip of master (d63aca6e).

I’m on master too and the “regular offset” button up to “touch off” causes this problem too

@phillc54 thanks for the detailed bug report. based on this, it’s pretty clear I introduced the problem, so I’ll try to resolve it soon. For now you can probably just git revert the offending commit for local use.

The problem stems from how after G10 L2 ..., G10 appears in the list of “active gcodes” (stat.gcodes[2]); then the new code added at 001eb00313d28a872b275acbc29407f5266a0f42 tries to issue a G10 code as a part of preview generation.
