G30 Insufficient Axes Homed For Bed Probing

@steve-lynch What;s teh error message exactly? And did you put that S2 in the second G1 Z move?

Steve Lynch

G28! (in a little exclaimation Triangle) then below it it says G30 insufficient homing for bed probing

uncommented fthat line, and added S2 to the second Z5...

G1 S1 Y50 ;then move slowly to Y axis endstop

These need to be negative moves again to go back towards the endstop.

And if you're using the BLTouch, just remove these entirely. M401 ;deploy mechanical z probe and M402 ;retract mechanical Z probe. They are not needed. The probe pin will deploy automatically with G30. Deploying it before your other moves risks it either hitting the bed and causing an error, or getting caught on something and breaking.

Steve Lynch

Yeah, That's what I thought.. DC42 Told me to put them back in... I didn't specify what Build I was on... I read that that is handled by Type 9 probe now. Cool!
Thanks!

Steve Lynch

UGH! Still! G30 Insufficient Axes Homed for Bed probing!

we trim more and more off each go-round, but still we do not kill the error!

@steve-lynch can you post your homeall one more time?

@Steve-Lynch That - and also your deploy probe and retract probe macros - there could be a move in there that needs an S2

EDIT. Inore that - you aren't now using them

I posted the deploy and retract above.. they're really short...

deploy just contains M280 P3 S10 I1

retract contains: M280 P3 S90 I1

Steve Lynch

Honestly, the more we cull from the Homeall.g, the more I see just how much unnecessary, redundant, and counter intuitive stuff I had going on there... It's like the file was fighting against itself.. lol

Phaedrux

Can you confirm that when you hit home all the X and Y axis start moving towards the endstops and actually hit them?

You can remove the second Z lift as well. It's already lifted once at the start of the file, so no need to raise it again. This one before the G90. Though it shouldn't be causing the problem.

G1 S2 Z5 F6000 ;lift Z relative to current position
G90 ;absolute positioning

Try again stepping through the file one line at a time by copying and pasting each line exactly as you you have it in the homeall file, into the console. But before you do that, cycle the power so that you start with all axes un - homed. If you look at the "Machine Control" tab, you start with all the axes highlighted in yellow. So switch to the console, enter the first commend, then switch back to the Machine Control tab. Then repeat for the next command in your homeall file. Every time an axis homes successfully, (i.e. an endstop triggers when the move has an S1 command) each one will change from yellow to blue. At the end of the sequence, they should all be blue. If not, where did it go tits up?

Steve Lynch

@phaedrux yes, they physically hit the end stops, at which time they clear the "not homed" status.

X, Y, and Z

Phaedrux

Yes when X and Y hit the endstops they should be marked as homed, that is correct. Are you saying they also mark the Z axis as homed?

Can you post your config.g file so we can see what your endstops are configured as?

Steve Lynch

it looks like the very first G1 Z5 F6000 S2 is the culprit

Steve Lynch

excerpt from my config.g

; Axis Limits
M208 X-8:300 Y0:300 ;Set Axis Limits

; Endstops
M574 X1 Y0 S1 ; Set active low and disabled endstops
M591 D0 P1 C3 S0

; Z-Probe
M574 Z0 S2 ; Set endstops controlled by probe
M307 H3 A-1 C-1 D-1 ; Disable heater on PWM channel for BLTouch
M558 P9 H5 F120 T9000 ; Set Z probe type to bltouch and the dive height + speeds
G31 P500 X-39 R0.2 Y0 A3 Z1.34 ; Set Z probe trigger value, offset and trigger height
M557 X50:230 Y10:270 S50 ; Define mesh grid

Steve Lynch

should the Y axis be negative here as well? Or is the end stop establishing "Hard Zero"?

Steve Lynch

OK, didn't I read that Z cannot make a move without Homing the other exes first? I had the comment to allow moves before homing, but I was told to remove that. S2 denotes a move ignoring limits though, correct?

Why do you think that? What happens? What should happen is that the bed moves 5mm away from the nozzle and nothing else. You shouldn't get an error message. The homing state won't change because of the S2 parameter. If you do get an error message at this point, try deleting that line and re-typing it, just in case there is a hidden character or some such that is screwing things up.

You can move Z if you include the S2 parameter. S2 ignores end stop detection.

M574 X1 Y0 S1 ; Set active low and disabled endstops

This looks odd.

; Axis Limits
M208 X-8:300 Y0:300 ;Set Axis Limits

That would indicate that your X axis is potentially longer than just 300mm. It's 308 actually. so in the rare case that your X axis is all the way to the max end, it won't be able to reach the endstop switch if your homing file only tells it to move 300mm. So your X axis homing move would need to be more than 300.

So your first X and Y moves should be:

G1 S1 X-400 Y-400 F10000 ;move quickly to X or Y endstop and stop there (first pass)
G1 S1 X-400 F10000 ;Now do a fast move just on X and detect end stop
G1 S1 Y-400 F10000 ;Likewise Y

S2 denotes a move ignoring limits though, correct?

The G1 S2 switch will allow that move even if the axis isn't homed. So for the Z axis, it is raising it out of the way a short amount to prevent any collisions.

; Endstops
M574 X1 Y0 S1 ; Set active low and disabled endstops

This is incorrect. Y0 indicates there is no endstop for Y.

https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_Set_endstop_configuration

If the X and Y endstops are on the low end, it should be M574 X1 Y1 Z0 S1
