Homing Issues

Hal

It is all good I caught it before it even touched the bed. So I do not believe that I am Not Not inverted.

goodness I am not sure what this is.

Here is my homeall.g:

G28 X ;home x
G28 Y ;home y
G90
G1 X150 Y150 F4000
G30 ; Do a single probe to home our Z axis

Phaedrux

What happens if you manually issue a G30 command?

Hal

Probe deploys, bed moves up, hits probe, the probe retracts, then the z axis moves down a few mm for clearance. I believe this is the correct process.

I did have to home x and y before I could issue the G30 command

Phaedrux

But you still get a homing failed error along with the servo error?

Funny enough I did not, and i only get the servo error if i try to print.

Phaedrux

Are you manually calling M401 and M402 anywhere?

Phaedrux

Actually, now that you mention it, I was getting some servo error messages yesterday when I was testing stall detection as a z probe. I had commented out all of the M280 servo commands but I was still getting an error message occasionally. I didn't really think much of it. I looked for other M280 commands I might have forgotten but there were none.

Yes in my bed.g file

Hal

Well I figured out the M280 command error, it seems like I set my S3D to use P0 instead of P3, so made the change and boom no more M280 error.

I am still getting the homing errors and the M29 error.

maybe those errors are also causing my other errors, so here is my s3d start and stop process.

start gcode from s3d

M280 P3 S160 ; BLTouch alarm release
G4 P100 ; delay for BLTouch
G28 ; home
G29 ; auto bed leveling
G1 X0 Y5 Z0.2 F3000 ; get ready to prime
G92 E0 ; reset extrusion distance
G1 X250 E20 F600 ; prime nozzl

end gcode from s3d

M104 S0 ; turn off extruder
M140 S0 ; turn off bed
G28 X Y ; home x and y axes
M84 ; disable motors

thanks for any help.

Phaedrux

The M29 error is probably from having too many points in the grid. Try a higher s value and see if it will let you run it.

Phaedrux

Actually it looks like you haven't defined a mesh grid in your config.

Hal

should I even have that much in here as the Bed.g file should be called, or is that invoked from S3d?

Hal

alright down to 1 error homing error is still happening but auto bed leveling is running as expected.

I invoked the Bed.g file using M32 command.

maybe my issue is in the bed.g file now.

Thanks

You may not even need to use bed.g if you're using mesh grid compensation. With beg.g you're limited in points. It ends up being the same as just using a sparce grid.

Hal

now it seems like for what ever reason the bed moves down a bit (~.05 to 1mm) after the purge happens....why do my issues keep growing. ehhhhhhhhhh.

Phaedrux

Can you post the first 50 or so lines of your sliced gcode file?

Hal

figured it out, it was also a strange setting that was in simplify3d. printing well so far, the true test will start tonight.
