Issues with Homing Delta on RRF3



  • I just upgraded to 3.x and I am having issues homing. Once home begins all axis start to travel towards the endstops as expected. However it seems that 2 of the 3 delta axis reaches the end stop and one does not. All axis then start to jitter significantly around the endstops. If I manually use my figure to depress the endstop on the axis that was not reached the homing completes.

    Hi ,
    Have you checked that it work properly?
    Are they optical? Or mechanical?
    Web Control > Settings > Machine Specific > on the right you should see "Endstop". All are not in triggered status if they are not interrupted (or activated if mechanical).
    Can you manually interrupt (or activate) the endstop (the one problematic) and verify in the WC that the signal is properly passed?
    Do your endstop section in config.g look ike this?

    ; Endstops
    M574 X2 S1 P"xstop" ; Set active high endstops
    M574 Y2 S1 P"ystop"
    M574 Z2 S1 P"zstop"
    

    Did you already checked the conversion guide?

    Yes, they seem to be working properly, they are mechanical switches. I just checked them on the WC and they all trigger and toggle status correctly. The issue is not a single tower but which every tower is first to reach the end stop starts to chatter.

    Here is my old M574 command

    M574 X2 Y2 Z2 S1  ; set endstop configuration (all endstops at high end, active high) 
    

    Here is the new M574 command

    M574 X2 S1 P"xstop"
    M574 Y2 S1 P"ystop"
    M574 Z2 S1 P"zstop"			; set endstop configuration (all endstops at high end, active high)
    

    I have uploaded some videos showing the issue.

  • @aerouta my interpretation of the error message is that M350 has only one E value, but M92 has two E values.


  • Moderator

    Place your M92 E back along with the others and then specify the additional parameters for both extruders.

  • @aerouta I am not used with Delta printers so much, but M350 is missing the microstepping for Z, is this correct or should it be added?



  • @JoergS5 These commands were brought over from a properly functioning RRF2 config. I have tried adding "Z16". There was no improvement in homing..



  • @aerouta what does happen when you only home one axis? Does the stepper stop correctly when reaching end position? (all 3 steppers tested separately)
    E.g. G91 and G1 H1 X550 F5000 only.

    Testing whether every stepper has it's correct endstop assigned. Because the two videos could be explained by steppers trying to move on but not stopped because the endstop belonging to this stepper was not reached yet.

    My interpretation of the first video is: the left stepper is at the endstop, but endstop is not activated, so it tries to move on, the belt slipping over the pulley (so jitter), the vibrations propagate to the middle arm also. But the middle arm is IMHO not at the end position. You could validate by pressing the endstop before it reaches the end position. (lower speed to have more time...)



  • @JoergS5 The videos show that the first axis to reach the endstop begins the jitter. I tested each axis one at a time and confirmed what is seen on the video. Attempting to home one axis begins the jitter on that axis.

    Is there any changes from board V1.01 to V1.04 that could cause this? This was another change that was made. My v1.01 board developed an intermintate failure that resulted in both thermocouples to fault. I then purchased the .04 board and upgraded to RRF3. This is my first attempt to use the new .04 board.



  • @aerouta I have also a 1.04 board.

    The release history is here: https://duet3d.dozuki.com/Wiki/Hardware_Overview#Section_PCB_revision_history
    I cannot see something related to your problem, but check also.

    My last idea is that you have an endstop type which now needs the ! in the syntax, according to https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_RepRapFirmware_Num_3
    M574 X2 S1 P"!xstop"
    etc.
    Do you have your old config, did it use M574 S0? This would be S1 with ! now.

    You can also recheck the RRF3 upgrade checklist in https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview

    @aerouta said in Issues with Homing Delta on RRF3:

    Error: in file macro line 88 column 10: M92: array too long, max length = 1

    Does this error still show up when you send M98 Pconfig.g?

    Can you verify your firmware version by sending M115. It should be 3.1.1

    And please share your newly changed config.g

    Can you test your endstops by hand and watch the DWC machine page for the endstops. When looking at the front of the printer, the X tower is on the left, the Y tower is on the right and the Z tower is at the back. +X movement is to the right and +Y movement is towards the rear. Verify that when you press the X tower endstop the X endstop triggers, etc.

    I wonder if maybe an endstop plug is swapped or not working.



  • @Phaedrux I conducted the test you suggested. Endstop index 0, 1, 2 triggered on towers X, Y, Z respectively.

    I no longer get the M92 error during the M98 command and my firmware version is confirmed to be 3.1.1

    Can you alter your M350 and M92 lines to include the Z and E axis respectively? And lets include an explicit M584 to map the drivers to their respective axis.

    You have:

    M350 X16 Y16 E16 I1    				; Set 16x microstepping with interpolation
    M92 X106.667 Y106.667 Z106.667		; Set axis steps/mm
    

    Change it to:

    M584 X0 Y1 Z2 E3 ; Driver 0 controls the X motor, 1 controls Y, 2 controls Z motor, 3 control E motor
    M350 X16 Y16 Z16 E16 I1    				; Set 16x microstepping with interpolation
    M92 X106.667 Y106.667 Z106.667 E470		; Set axis steps/mm
    

    Then you can remove the M92 E470 that occurs lower down in the config.

    Also, I'm not sure it matters, but when comparing to a fresh delta config from the web tool, the M665 delta commands are placed higher in the config.g file near the top before all the drive commands.

    Here it is for comparison:

    @aerouta config.g looks okay, except there's an extra M92 at line 82, but as it's the same as the earlier one, it shouldn't cause a problem.

    Did you disconnect any motors or endstops, or rewire the machine? Because it really sound like two of the endstops (or motors) have been swapped, so are not related to the correct axis. That's why 2 of the 3 axes reach the endstop; one correctly hits the endstop and stops, one hits the endstop and stops the third, but continues to move, as the third hasn't hit the switch that would stop the second, until you press it with your finger.

    Move each motor individually so you know which tower is which, by sending G1 H2 X10 F100 (which will move just the X axis). Then press the switch on that tower, and check it activates the X endstop (send M119 to check status or check in DWC > Machine-Specific > Endstops). Repeat for the Y and Z towers.

    Ian



  • @droftarts Yes, I did switch from a 1.01 to a 1.04 board. I will recheck all my motor and endstop connections.



  • @droftarts the motor connects were switched! good catch!
