If you start missing steps your machine will still crash without limit switches... If you comfortable with that its all good... but don't tell people that they don't need limit switches if they have home switches... the two serve very different purposes
So do you no longer need you home button like you had on the video of touch probe? I just ordered some limit switches so I can have the machine auto home at startup. Then I will use the touch plate.
Correct. The screen options on LinuxCNC change when you set it up for to automatically home the machine. Originally the button said "Home Axis", you would pick X, Y, or Z, and click the button. After adding auto homing, the button just says "Home All" (where it runs through process of finding your switches when clicked). You do not have the choice to manually set the machine's home at that point - only the machine will do it with those settings. After auto homing is set up, you use the button "Touch Off" to set X, Y, Z for the part you are working on (or the touch plate process for Z).
OK I'm working again thank you. So my touch off plate is .124 thick. I changed you code to -.124 and it ends up at the top of the table. I can't re-home since it does all of them again? Do I just let it find the table top and then move to the part and use the touch off for all three axis. I sorry I am so new to this but I do see when it is a set up I can make anything.
You need to home the machine's work area / G53 (what this homing process does), and home the part you are working on (G54). The touch plate sets zero for the part you are working (G54). For the X & Y, I just move the machine to where I want the X/Y zero to be, and then click "touch off" for X and for Y. Also, you will want your screen to show the part coordinates (G54), and not the machine coordinates (G53). In LinuxCNC, click on "View", and then at the bottom make sure you click on "Show Relative Position".
I like the smile face

Nice!
