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.

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

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?

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?

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.

But they both take multiple points from the bed to adjust for any misalignment so I guess I can see the difference in the way the do their calibrating based off those points, but in the end both styles (probe or microswitch) should go through the autolevel procedure. It seems you are saying the robo cant do this with the microswitch?

@dc42 thank you.

@dc42 would you mind if you have a moment looking at the config.g and bed.g file i uploaded and let me know why my I am getting a error code for autolevel when i try to print I also have a fan issue but will get to that later. I want to finish with autolevel .

https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors i think i was supposed to do this calibration not the other probe calibration i was doing?

sleepless

not sure where in config.g this goes
M584 X0 Y1 Z2:5:6 ; three Z motors connected to driver outputs 2, 5 and 6
M671 X-15215 Y190:-10:190 S0.5 ; leadscrews at rear left, front middle and rear right

@dc42 Error: Z probe already triggered at start of probing move

That means what it says. The Z probe reading at the start of the probing move, before the probe triggers, should be zero. If it's 1000, change I1 to I0 or vice versa in your M558 command.

Error: G29: No valid grid defined for bed probing

That means you haven't used M557 to define the probing grid. See https://duet3d.dozuki.com/Wiki/Using_mesh_bed_compensation.
