Just really started using grbl and LB
Just really started using grbl and LB. I have the LO z axis table which works fine in smoothie. When I try to get the z axis to move, i get the following error and LB completely locks up.
Starting stream
ALARM:2
On or near line 1:
Stream completed in 0:00
[MSG:Reset to continue]
Only wayI found to continue is close LB and start again.
Here is my configuration:
$0=10
$1=255
$2=0
$3=3
$4=0
$5=1
$6=0
$10=0
$11=0.010
$12=0.002
$13=0
$20=1
$21=0
$22=1
$23=1
$24=50.000
$25=6000.000
$26=250
$27=2.000
$30=1000
$31=0
$32=1
$33=5000.000
$34=0.000
$35=0.000
$36=100.000
$100=160.000
$101=160.000
$102=3200.000
$110=24000.000
$111=24000.000
$112=500.000
$120=2500.000
$121=2500.000
$122=2500.000
$130=300.000
$131=200.000
$132=50.000
$140=0.400
$141=0.600
$142=0.000
ok
It did not work with the original value in $102=160.
I believe the stepper is a 42HS03. Any help will be greatly appreciated.
I’m using the version of gbrl download from the cohesion site.

Is this an external stepper driver driving the Z bed, as shown in our Z Table article?

Alarm 2 is machine exceeding travel.
You probably need to change $132 to the z table travel length. Increase the default 50mm to a larger value.

Yes it is with an external driver.

Changing $132 didn’t make a difference. I tried to move the z several times and could occasionally get it to move - not very often but when it did it moved in the wrong direction. Again it works exactly as it always has using smoothie. When it did move using $102=1600 it only moved .5 mm rather than the 1.0mm set.

+Jim Fong any further ideas? Any more info I can add?

Since you say the Z is going the wrong direction, you need to modify $3 setting to change the direction.
Change $102=3200 to double the distance traveled.
