setup for gantry with linuxcnc 2.7.5.

Have a challenge setting up a gantry machine with linuxcnc 2.7.5. with trivkins and gantry.comp
setup is : XXYZ
Have ini setup for 3 axis : axis0 axis1 and axis2 and 4 joints joint_0 till JOINT_3
Challenge: hall file generate and error as i have to connect the analog and encoder outputs of a mesa 7i77 board to both axis_0 and joints_0 as wel as to axis_1 and joint_1 and axis_2 and Joint_2

LinuxCNC Master now handles gantries much better and can home an axis with multiple joints or motors.

Thanks JT this helps and explains a lot

Short on time yesterday...
linuxcnc.org/docs/devel/html/config/ini-...lt_letter_gt_section
and
linuxcnc.org/docs/devel/html/getting-sta..._configuration_files
anyhow in Master (pre2. you configure each joint (motor) and each axis. An axis can have more than one joint. I looked for a good example but came up a bit empty. When you take a valid 2.7 configuration and open it up a converter attempts to convert it and save a copy.

working on 2.8. master branch now, but can't open the window for calibration or Hal configuration, from the Machine dropdown

Are the menu items greyed out? Just checked a machine and the Axis sim and both windows open. Check with the Axis sim.

JT

Hi JT,

Even if i open axis.sim, both calibration, and hal configuration don't show, everything else does run ( like hal-scope )

How did you install master?

JT

followed the: buildbot.linuxcnc.org/ link
and have chosen the:
deb buildbot.linuxcnc.org/ wheezy master-rt
deb-src buildbot.linuxcnc.org/ wheezy master-rt
Then sudo apt-get update
sudo apt-get install linuxcnc

I tried to set up Debian with Master this morning but failed to finish.

Edit your ini file and turn on maximum debug statements by commenting out the DEBUG=0 line and add like this

Open a terminal and clear dmesg
Close that terminal and open a new one and launch linuxcnc
Open Axis and try to open the calibration page and see if you get any errors. I'll try again in the morning to install debian and master.
