Auto Bed Leveling issue
February 13, 2018 01:48PM
I've just built a Tevo printer. It has an auto-levelling probe and I set up the firmware with "FIX_MOUNTED_PROBE" as the probe type. When I clicked on "Z home" on Repetier Host. it went up in Z and would probably have gone through the topof the printer if something had not been in the way. So then I looked at my configuration and changed "#define Z_HOME_DIR -1" to plus 1.
But when I upload, I get this error:
#error "Enable USE_ZMAX_PLUG when homing Z to MAX."

If you want the Z to home to where the nozzle is close to the bed, then you had it correct the other way, with Z_HOME_DIR set to -1. This is USUALLY the way that these printers home.

If you want it to home as far away from the bed as it gets, then you need to have a limit switch attached at that point.

More likely what you want to do is find the

#define INVERT_Z_DIR false

line in your configuration.h and change it, so that the motor turns in the direction that you need in order to move in the expected direction.
