[grbl Issue#1264] GRBL 1.1e for Atmega2560 Probe ERROR About GRBL HAL

Issue #1264 | 状态: 已关闭 | 作者: zygimantasmikulis | 创建时间: 2017-07-20

Hello,
so I am having this issue I use grbl 1.1e with arduino mega 2560. For cnc milling I use Candle_1.1.7 and it has hightmap function for pcb milling. The problem is that when the probe touches plate machine stops and I get ERROR:9
When doing just probe function I get in to allarm:3 state and get this message.
G21G91G38.2Z-30F100 < ALARM:3 ok G0Z1 G38.2Z-2F10 Grbl 1.1e ['$' for help] [MSG:'$H'|'$X' to unlock] This is example video how it should work https://youtu.be/tK5Amg-Ye58

And this is how it looks for me when the probe touches plate.

I do homing cycle but still the same error.
I disable homing still the same error.

Grbl is getting placed into an ALARM state for some reason. According to the wiki and other documentation, ALARM:3 is caused by a ‘Reset while in motion’. Meaning your system is being reset for some reason. Maybe you have a reset button and its poorly isolated. error:9 is just the standard Grbl response for trying to command something in an ALARM state. It blocks all gcode.

Somehow I only get this reset error when I am probing. The probe touches plate, it stops and the system shows error:3 and resets.
Probe setting is
$6=0
Probe circuit is
!511568b7ce395f613f000004
Also I have noticed that when I do not engage Z in a movement but just touche probe contacts system just resets and no error:3.

Please provide your $$ settings and your $I build info string. Also which pin is your probe connected to?

I apologize for my stupidity. I have just noticed that probe pin is MEGA2560 Analog Pin 15 and I have connected my probe pin to Analog Pin 11. It is because I use my made and traced controller and connected to wrong actual pin of proc. and all the time I was shorting pin to GND and resting processor
