I just broke (another) limit switch by entering a bad command in machine inspector. I also learned that the limit switches aren’t active in MI, and the Z axis went the opposite way I expected.

Just happened to read this and if this is old data and you have solved your issues — just disregard.

These are configuration issues. Your machine can take care of these problems below the Easel level. Grbl has settings to help eliminate these problems. Use homing and soft limits.

For some of your positioning problems, look into the G28 and G28.1 G-code commands.

Take a look here:

Homing/Limit Switches

Looking at things from the grbl perspective, the term “limit switch” only applies for the X-carve if you use hard limits ($21=1) . Looking at things from the grbl perspective, all other cases for the X-carve the switches are “homing switches”. Homing switches allow soft limits ($20=1) to work. For this case the “limits” depend on having done the homing cycle and on the low end the limits are 0,0,0 and the limits on the high end are set by $130, $131, and $132. After the homing sequence the swi…
