Stall detection tweeking from 2.05 to 3.3.0 RC3
-
Hi there Guys,
i just finished it to update my Firmware from 2.05 to 3.3.0RC3 and got a small Problem.
This is how i homed my X Axis:
; This File is just for testing the "stall detection" Feature. ; It might need to be adjusted to get it to work with you're Printer/s ; Sensorless Homing test file for RepRapFirmware on D-Bot ; M915 X S3 F0 R1 ; More about M915 and how to set it up you can find here: ; https://duet3d.com/wiki/G-code#M915:_Configure_motor_stall_detection ; Lift Z relative to current position G91 G1 Z10 F6000 S2 G90 ; Setup Stall Detection on CoreXY for Xmin Xmax M400 ; make sure everything has stopped before we make changes ; M574 X3 Y3 S3 ; set endstops to use motor stall M913 X30 Y30 ; reduce motor current to 50% to prevent belts slipping G91 ; use relative positioning G1 S3 X-500 F4000 ; move the X to max until it detects the min Point G92 X0 ; set X min Point ;G1 S2 X30 ; move X away from min Point M400 ; wait untill X is done G1 S3 X500 F4000 ; move the Y to min until it detects the min Point ;G1 S2 X-30 ; move X away from max Point M208 ; shows the way that has been traveled G90 ; back to absolute positioning M400 ; make sure everything has stopped before we reset the motor currents M913 X100 Y100 Z100 ; motor currents back to normal ; M574 X1 Y2 Z1 S0 ; set endstops back to normal (is maybe different than you're normal) G1 S1 X150 ; Lift Z relative to current position G91 G1 Z-10 F6000 S2 G90And it does nothing and just says:
Warning: Obsolete use of S parameter on G1 command. Use H parameter instead. Error: Homing failedI tryed H1 instead of those S Commands, but it didn't worked for me.
How can i fix that?Best regards

@as-3d-druck have you modified your config for the new endstop settings etc?
-
@jay_s_uk yes
-
@as-3d-druck ok
-
@jay_s_uk no Idea?

G1 S3 X-500 F4000 ; move the X to max until it detects the min Point
well you're telling it to home one way
G1 S3 X500 F4000 ; move the Y to min until it detects the min Point
but then you're going top opposite way
G1 S1 X150
and then that same way again which seems to be confusing things
Also, S3 (which as pointed out should be H3) does this
H3 terminate the move when the endstop switch is triggered and set the axis limit to the current position, overriding the value that was set by M208.
I think that also would fail as theres currently no position to set as the axis limit as the axis isn't homed.So I suggest you check which direction you should be homing in and change to H1
-
S3 is for motor stall, but that only belongs in the M574 command. Homing moves when using stall detection are still H1.
Can you post your config.g as well?

It dosen't want to move Z even.Best regards

M574 X3 Y3 S3
X3 Y3 is not valid. It must be either 1 or 2. 1 is low end of travel, 2 is high end of travel. S3 is correct though for stall detection.

The Z moves are the only place where H2 is correct. H1 means seek the endstop. H2 means move the motor regardless if it's homed or not.

I tryed this for now with no moving Axis.

G1 H2 X5 F12000 ; go back a few mm
Should probably remove the H2 from that one.

Meaning nothing moved?

Okay i got it now kind off.
My Problem was i got in my config before (2.05) steps M92 and after that M350 for interpolation on those steps etc. but in this config as you can see before i got it the other way around.
So i changed that and now i got movment back.The only thing that i try to fix is now why it runs to the set direction is on the End and still tackles it a few times and than sets back to the middle as intended.
I currently try to change the sensitivity but still not great.

Got it now on 4 and it seems to work -

I'm not sure what that means.
But sounds like you got it working now?

Yes, i can provide my new Home X and Y File + Config if someone wants to look at it. (Troubleshooting etc.)
