You invert the Z probe trigger using the I1 parameter in the M558 command. Example:
M558 P5 I1
Note, that's uppercase-letter-i (not the vertical bar character) followed by digit 1.

I'll give it a shot ty

ok were moving along here... I raised the z 100 then homed x then y then sent g30 command and used my hand to lift the x axis and test trigger the z probe/endstop. that worked. when I homed x and y then ran g30 again to allow it this time to reach the bed it didnt get to the bed and sent an error message that the z probe couldnt trigger
-
Was the Z probe over the bed when you ran G30 again? Typically in homez.g and homeall.g you would use a G1 command to move the head to a suitable XY position (e.g. the centre of the bed) before the G30. See https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_Z_using_a_Z_probe.

it was not over the center the x and y were homed and then i sent the g30 command. I did try something while I was waiting for a response and it seems to have worked. I added G28 to the bed.g and m574 to the zprobe area in the config.g I will post copies

got Z-0.85 and i put that in the config.g

How do i run a auto level test to make sure its working properly?

That doesn't sound right, because it means that the Z probe triggered when the nozzle was 0.85mm below the bed surface. If it triggered when the nozzle is 0.85mm above the bed surface, then use Z0.85 in the G31 command in config.g.
-
it actually triggered -1.38 but that was too close to the bed so i raised it until the paper had a little friction going under. i loaded a test gcode and it seems the auto level is way off. it is probibing 11 points across the x axis and i lost count on the y axis. it is also only going about 60% of the way on the x axis when running the auto level.It started around the center of the bed instead of the front corner of the bed. (Side question how do i increase the movement speed for homing)
-
It sounds to me that your Z=0 level was off when you started. before you measured the trigger height, did you lower the nozzle until it was just touching the bed and then send G92 Z0, as described at https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe#Section_Calibrate_the_Z_probe_trigger_height ?
-
no i misunderstood the directions. I raised the z axis 10 each time before running G31
-
M557 X15:215 Y15:239 S20 I was curioius if the S20 in this code from the Zprobe area in the config.g file was the number of probing points? Also how do i increase my homing speed?
-
I am trying to run the test and calibrate again as your recommended. But I am running into an issue. I centered the nozzle over the bed using the jog controls, i lowered the z until the nozzle gripped a piece of paper, then sent command G92 Z0. Then tried G30 S-1 and i would receive error message insufficient axises homed. What am I doing wrong?
-
I think my steps are wrong. When i am homed on the x it is 230 but when i move the x with the jog 100 or so it zeros out the x and im only at the center of the bed, its the same for the y

// default settings
#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,800,723.38} // default steps per unit for RoBo 3D R1
I used the above when creating the config in the reprap website. I believe i chose 32steps

ok i doubled my e steps and now it looks appropriate. I will go ahead and run the test and calibration again now

when i try to configure and claibrate the z probe. I center the x and y after homing them.then lower the z until it grips paper and send the g92 z0 command. zeros out the z.
then i raise the nozzle by 5 and run g30 s-1 and the nozzle is too close to the bed. the values are still negative.
What am I doing wrong here. I cant seem to get it to probe and leave the nozzle at the correct height for it to grip the paper -
tried a test print
and got Error: Z probe already triggered at start of probing move
Error: G29: No valid grid defined for bed probing
