Attempting to Run Autoleveller077.jar in LinuxCNC 2.5.0

[oliverthepig]

Hi Everybody,

I was looking to try the levelling software with LinuxCNC 2.5.0

I'm having some difficulty getting the Jar file to run,

I've installed the Java enviroment, when I run the .jar file nothing happens,

Just seeking some help in getting it running.

Cheers Dave

Hi Dave,

I will check later when I boot into Linux but you need java 1.7 or later installed.

Code: Select all

java --version

at the console will tell you I think.

After that

Code: Select all

java -jar Autoleveller077.jar

should work. As I said I'll check later.

Hi,

I sorted out the Java Problem, with LinuxCNC. I had to uninstall an old version before it would let upgrade.

I've loaded the gcode using the Autolevel software, setup the probe input, which works okay using HAL.

The gcode runs the bit down to the copper and stops at line 23, with an error of P value out of range, with G10 L2 and L20.

Any help would be appreciated.

Cheers Dave

P0 doesn't seem to work in some versions of LinuxCNC. Try changing P to P1. That line should now be:

Code: Select all

G10 L20 P1 Z0

Hi,

Thanks for your responses so far,

I've updated to LinuxCNC 2.5.3 which has cleared the last errors which has stopped the code from running,

I've introduced a new bug however. The Z Axis no longer zero's when I press the home button. It seems to to go some random value. When I start linuxCNC from scratch the z axis does not start from zero which I haven't seen before.

I've done some googling and think it may have something to do with a tool offset,

any thoughts would be appreciated.

Cheers Dave

Im at work at the moment and dont have my linuxcnc to hand. However, off the top of my head, maybe your ini file got changed somehow. Here is an old backup of my_cnc.ini:

Z is [AXIS_2] and HOME should read 0.0. If yours is different then you might need to change the value.
