For the grid point skipping that will happen when the probe can't reach the point you've set it to probe.

You'll need to set the grid size taking into account the offsets of the probe.

For starters though you should verify that you can actually reach the extents of travel you've defined with M208. With the nozzle at 0,0 which should be the center of the bed, can you actually move 115mm in every direction from there?

Have you measured the distance of the probe from the nozzle accurately?

For the heaters, they likely just need to have a tuning cycle.

@adalton5683 Probably best to ask your CNC question in a new thread in the CNC forum for some more visibility.

Where is the nozzle when the endstops are actually hit?

If the nozzle is off the bed edge then you can set the axis minimum to a negative value such that 0,0 is right at the corner of the bed.

But I don't understand how you have negative values at the bottom left corner if your endstops are at min and set the axis to 0.
