💡 Hint

Common Mistakes

Using G00 which is a rapid move and does not probe.

Using M30 which ends the program.

Using ZPROBE which is not a standard G-code.

G38.2 is the standard G-code command to start a probing cycle that moves the tool until it touches the surface.

💡 Hint

Common Mistakes

Setting zero on X or Y axis instead of Z after probing.

Using G instead of axis letter.

Omitting the axis letter.

G10 L20 P1 Z0 sets the Z-axis zero position at the current location after probing.

💡 Hint

Common Mistakes

Using X or Y axis which probes horizontally.

Using G which is not an axis.

Omitting the axis letter.

The probe must move along the Z-axis, so the command should be G38.2 Z-10 F100 to probe downwards 10 units at feed rate 100.

💡 Hint

Common Mistakes

Using different axes for probing and zero setting.

Mixing X or Y axis letters.

First line probes down 5 units on Z axis. Second line sets Z zero at current position with G10 L20 P1 Z0.

💡 Hint

Common Mistakes

Using wrong axis letters for probing.

Setting zero on wrong axis.

First line probes X axis 10 units, second probes Y axis 10 units, third sets Z zero at current position.
