Sensor IR / BED
-
Hello, I know that surely this issue has been addressed, I cannot find the solution. I have an IR sensor, first calibrate the machine to make the 4 points where the threaded rods are, then it senses the bed, and this is the result. I need help., Thanks! I leave the configuration files and a couple of images[alt text](config.g bed.g image url)

Can you give us some more details about the printer?
Firmware version? Can you post the results of sending M122 and M98 P"config.g" in the gcode console?G31 P500 X0 Y0 Z-1.913
Your trigger height for the probe is set to nearly -2mm which means the probe is triggering when the nozzle is 2mm below the surface of the bed. That doesn't make any sense. You're also missing the X Y offset for the probe measured from the nozzle.Have you gone through this yet?

2.43mm sounds more reasonable. Did it have any effect?

What do you have in homeall.g?

Your homeall isn't using the IR probe to home Z. This is part of your problem.

So what do you have in homez? (which would get called next after homeall since Z axis wasn't homed)

hi this is my homez, i am using G30 here.

So in your slicer start gcode you're homing with G28, which probes Z at x150 y150 (correct? Or is it taking the X Y position you have specified in homez X38 Y0?) and then it calls bed.g (G32) which homes again. Then does 4 point leveling. And then calls G30 again. But where is that G30 in XY space? Same location as the last leveling probe point?
You should tidy things up a bit so that it's always setting Z0 with G30 at the same location, ideally in the center of the bed.
G31 P500 X0 Y0 Z2.43
Did you measure the X Y offset for the probe yet? Without that it will be applying Z correction at the wrong location for the actual nozzle position.

@phaedrux I personally prefer to probe Z on a point that's coinciding with one of the grid points. If I can't easily probe the center with the grid (for example due to probe offsets and probe point setup), I prefer to probe Z at the location of the first probe point since that's easily derived from the mesh definition.
