Problems with X axis when running tests
-
Hey,
I am a new member of 3d printing world and i am currently setting up my first 3d printer. It is a Caribou Duet 2 WIfi.
I managed to get everything connected and setup, but am currently running is some issues with my extruder running out of position on X axis. If i manually set the extruder in the middle of the bed, i can home all 3 axis and my Pinda 2 Z probe is working ok.
When running one of the tests the extruder is not following the limitations in the config/macro and it goes all the way far left, so my Pinda moves out of the bed. Since the test then tests PINDA aswell, it lowers my extruder on Z axis without ever stopping and crashing into the bed.
Here is my config :
Anyone can help me out with how to limit the extruder to not move all the way to the end, but to stop beforehand?
Thanks in advance!

What tests are you running?

Hey, thanks alot for a reply.
I always thought a Gcommand M574 takes care of the enstops? Ofcourse i might be dead wrong and might be missing something major, but here is the Level-X axis test i have been struggling with:
M913 X100 Y100 Z100 ; set motor currents to 100% G91 ; relative positioning G28 ; home Axes G90 ; absolute positioning G1 X125 Y55 F6000 ; move extruder to the middle of the X axis M564 S0 ; disable minimum and maximum axis limits G1 Z305 F6000 ; Move Z axis just below top M913 Z40 ; reduce Z motor current to 30% of set current G91 ; relative positioning G1 H1 Z15 F300 ; move Z axis 20mm up slowly levling the X gantry M913 Z100 ; return Z motor current to 100% of set current G90 ; absolute positioning M564 S1 ; enable minimum and maximum axis limits M208 X256.9 Y214 Z316.50 S0 ; set axis maxima G1 X11.5 Y4.5 Z10.0 F6000 ; go to first probe point M400 ; wait for current moves to finish G30 ; probe bedI alos have M208 command included in cofig file, where i tried to limit the movement of the axes, but not sure if that works in the way i thought
I downloaded the config and macros of the github, both were made directly for the version i am using - Caribou3d Duet 2 Wifi 320 with SE thermistor and PINDA2.
Any further help on how to get the tests up and running and start printing would be greatly appreciated!
Best regards,

@beyondx said in Problems with X axis when running tests:

It does, but you have m574 for both sensorless and endstops.
M574 X1 S3 ; configure sensorless endstop for low end on X M574 X1 S1 P"xstop" ; X min active high endstop switch M574 Y1 S3 ; configure sensorless endstop for low end on Y M574 Y1 S1 P"ystop" ; Y min active high endstop switch M574 Z1 S2 ; configure Z-probe endstop for low end on Z M574 Z2 S3 ; configure sensorless endstop for high end on Z M591 D0 P2 C"e0_stop" S1 ; configure extruder endstop (filament sensor)So only the second instance will take effect. So first it sets sensorless and then sets endstops. So if you're trying to use sensorless you should remove the endstop m574s.

@phaedrux
Would then removing the endstop and only keep sensorless, cause that extruder would be moving base of the limits set with M208?Additionally, would this kind of removal of endstop switches in M574 successfully run the provided macro as well?
Thanks in advance!
-
Does the printer have actual endstop switches or not?
If you have them, I would suggest just using them.
Either way, if you want to use sensorless homing you need to remove the M574 commands that define the endstop switches and leave the commands that define sensorless homing.

@phaedrux
I do apologize for a late reply!Thanks for the help thus far. I have double checked and indeed tehre is no physical endstops, so i will go with sensorless homing.
That being said, when i tried to do the tests again i am running into the problem with homing X axis. The homing goes through normally, but i still get a G28 X Error: Homing failed.
I am not sure if i am missing a G28 code at all, but Y axis is home normally.
Attached both homex.g and homey.g fileWhat am i missing?
Thanks in advance for the help!
-
What do you have in this macro?
M98 P"current-sense-homing.g"
If Y works but X does not that may mean that X needs a different motor current or sensitivity setting. You'll need to do some tuning to get reliable stalls.
-
@phaedrux Hey, thesae are the two homing files.
For stallguard sensitivity i have these:
; Stallguard Sensitivy
;
M915 X S2 F0 H200 R0 ; Set X axis Sensitivity
M915 Y S1 F0 H200 R0 ; Set Y axis Sensitivity
M915 Z S0 F0 H200 R0 ; Set Z axis SensitivityBest regards,

What kind of a tuning process did you use to arrive at those values?
