Almost there. There isn't a gantry.hal file on github that I can find to reference. I set up the Kinematics and added the new switch being careful to not have a name conflict. I copy/pasted the joint for the current Y axis (JOINT_1) creating JOINT_3. I then replaced the 1 in that section with 3 to create the new joint. When I start LinuxCNC I get an exit because ypos-cmd, ypos-fb, ystep and yenable have already been assigned during the JOINT_1 setup. With those lines commented out I can get a startup and 4 joints showing on the screen. The relevant hal section, a copy of JOINT_1 is: setp stepgen.3.position-scale [JOINT_3]SCALE setp stepgen.3.steplen 1 setp stepgen.3.stepspace 0 setp stepgen.3.dirhold 65000 setp stepgen.3.dirsetup 65000 setp stepgen.3.maxaccel [JOINT_3]STEPGEN_MAXACCEL net ypos-cmd joint.3.motor-pos-cmd => stepgen.3.position-cmd net ypos-fb stepgen.3.position-fb => joint.3.motor-pos-fb net ystep <= stepgen.3.step net ydir <= stepgen.3.dir net yenable joint.3.amp-enable-out => stepgen.3.enable net home-y-right => joint.3.home-sw-in I am not finding the place in the docs telling me what to do with these lines. Delete them? Rename the variables? I didn't do this as I couldn't find other references which leads me to think they may be fixed names used by the code.
