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

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

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 ?

sleepless

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?

sleepless

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?

sleepless

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

sleepless

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

sleepless

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

sleepless

G28 ; home all axes
G29 ; probe the bed
G1 Z5 F5000 ; lift nozzle
M109 S[extruder0_temperature] ; set the extruder temp and wait
G1 X0 Y0 ; move to begin wipe
G1 X20 Z0 F4800 ; wipe here is my beiginingg script for S3D

sleepless

do i need to change g29 to m557 in my simplify 3d scripts for auto leveling? or rather to define the mesh grid?

Phaedrux

The M557 command to define your grid area may have unreachable areas. This gets complicated because you technically don't have a z probe. So you cant really probe the bed. I would just use g28 to home the printer until you get an actual probe.

sleepless

thanks for the advise. after reading this forum i was under the impression I could keep using the original auto level style of the machine. https://forum.duet3d.com/topic/4737/zprobe-robo3d-r1

Phaedrux

Yes it could auto level the x axis, but that's not the same as probing the bed.

sleepless

@phaedrux hmmm i am confused would you mind clarifying the difference for me. Sorry and thank you

Phaedrux

A probe is normally attached to the print head and is movable to all areas of the bed so it can find the height of the bed across its whole surface. This can be used to get an idea of how the bed lays in relation to the print head.

What you have is two end stops in line with the x axis. This lets you adjust the tilt of the x axis to match the bed. But this is just a straight line between the two z motors. This lets you keep the z axis level on both sides, but that's about it.

Does that make sense?

S20 is the spacing (in mm) between probing points.

Homing speeds are set by the F parameter in the G1 S1 commands in the homing files; except that if you home Z using a Z probe, then you will use a G30 command to home Z and the speed is the same as for all Z probing moves, as defined by the F parameter in the M558 command.
