MPX3 board + DMS DP5 printer

Hi, I use MPX3 board and have this issues:
- after using dev version and choosing MPX board, heatbed do not work. When I switch back to 0.9.2.9 it works
- after autoleveling, which works perfect, I cannot print, as head is on new level, cca 3mm above set autolevel (any fw version). Setting slicer or firmware Z correction does not work.

Thanks for any advice.

    Thanks. I found a mistake by copying code from marlin from that board it did not adjust to correct naming scheme, Please try the updated version for heaters.

    Regarding autolevel you z probe height seems to be off 3mm resulting in wrong height calculation.

    Thanks a lot, I will try dev version toady. Please, can you recommend the right height calculation method? I probably misunderstood. Thanks a lot.

    See


    it also explains how to do it with the lcd in dev version.

    Hi,
    I used set it up this way - go manually down to cca 0.1 (thin paper), then trigger the probe and tighten probe screws. Then tune up Z-probe height value until the Z is OK (gap 0.1 mm). It worked with old printer, now prints cca 3mm above bed.

    When I use the repetier described method, the extruder push the bed little down when homing Z. But it prints correctly - unfortunately only first layer, then it "hops" another cca 3mm above 1st layer and print is bad.

    I use slic3r, no Z offset.

    This is my second printer, the first used  MKS Base V1.5 board, the same config.h, no problems. 
    MPX.3 seems to behave different way...

    HW: MPX.3 board, SN04-N probe, Steppers Busheng 17HD40005-22B

    Configuration.h - here

    Thanks for any advice..

    Your calibration is most likely missing correctness or is incomplete. When you are at 0.1mm nozzle distance the probe should already have triggered. You need to do it the other way around. Go down until it triggers and get z position. Then go down till nozzl eis on bed and note z again. The difference is z probe height which you need to use.

    Will try, thanks!

    So this method gives bad results - it is the same as it was - it prints cca 3mm above bed from the beginning... probably I have bad setup somewhere, I am desperate how to find... Do you think I could have bad steppers setup?
    Thanks.

    Do you have ALWAYS_CHECK_ENDSTOPS 0 ? If you have inductive/ir probe it might prevent coming down if using z hop and maybe some other cases.

    Also do you z max homing or have z probe = z min pin?
  • Posts: 34
    yes, ALWAYS_CHECK_ENDSTOPS 0
    have z probe = z min pin

    now I wanna add Z_max, but not homing Z_max

    You should first test G32 and see if after that G1 Z0 is at z=0. Correct z probe height by difference and try again. Make sure bed coating is set to 0. Then if G32 works try homing z. That should then have correct height. Best try with dev version, which has several fixes regarding z probe = zmin.

    Thanks, I use DEV version. I will try.

    It works perfectly, but then, after Z homing, ext0 goes up several milimetres and M114 reports Z = 0 (but it is in fact several milimetres up... thus, it prints in this distance above the bed.

    I start thinking, that the board has some failure, or I am stupid... :-(

    If the firmware is in laser mode, it can control a laser output to cut or engrave materials.
    Please use this feature only if you know about safety and required protection. Lasers are
    dangerous and can hurt or make you blind!!!

    The default laser driver only supports laser on and off. Here you control the intensity with
    your feedrate. For exchangeable diode lasers this is normally enough. If you need more control
    you can set the intensity in a range 0-255 with a custom extension to the driver. See driver.h
    and comments on how to extend the functions non invasive with our event system.

    If you have a laser - powder system you will like your E override. If moves contain a
    increasing extruder position it will laser that move. With this trick you can
    use existing fdm slicers to laser the output. Laser width is extrusion width.

    Other tools may use M3 and M5 to enable/disable laser. Here G1/G2/G3 moves have laser enabled
    and G0 moves have it disables.

    In any case, laser only enables while moving. At the end of a move it gets
    automatically disabled.

    I can´t find any reason, why it prints 1.9 mm above the surface... 

    Thanks for any idea...
  • Posts: 0
    You have the very special case of max and min z endstop. That seems confusing for the firmware as it takes routines meant for z max homing like computing the z length from distance to top, while neglecting the special problems in that case since #define MOVE_Z_WHEN_HOMED 0 is not good for z max homing but required for z min homing.

    Not sure if it comes from this but it is most likely that there is a connection.

    So please try deactivating z max endstop by setting hardware endstop false.

    Alternatively set homing direction 1 for z and #define MOVE_Z_WHEN_HOMED 2 and z min hardware endstop false.

    See if any of these combinations would work correctly, then we can start finding the firmware code adding the error. Thes eboth cases are used by many users so known to be working and if they work we know settings are correct and any error coming after enabling second endstop is in firmware code.

    So I set and will test:

    #define ENDSTOP_Z_BACK_ON_HOME 1
    #define MOVE_Z_WHEN_HOMED 2

    #define ENDSTOP_PULLUP_Z_MAX false
    #define ENDSTOP_Z_MAX_INVERTING false
    #define MAX_HARDWARE_ENDSTOP_Z false
    #define max_software_endstop_r true

    #define min_software_endstop_x false
    #define min_software_endstop_y false
    #define min_software_endstop_z false
    #define max_software_endstop_x true
    #define max_software_endstop_y true
    #define max_software_endstop_z true
    OK?
    Thanks, Ota

    No, you mixed the 2 cases.

    Case 1:

    #define ENDSTOP_Z_BACK_ON_HOME 1
    #define MOVE_Z_WHEN_HOMED 2

    #define ENDSTOP_PULLUP_Z_MAX false
    #define ENDSTOP_Z_MAX_INVERTING false

    #define min_software_endstop_z true
    #define max_software_endstop_x true
    #define max_software_endstop_y true
    #define max_software_endstop_z false

    Case 2:

    #define ENDSTOP_Z_BACK_ON_HOME 1
    #define MOVE_Z_WHEN_HOMED 0

    #define ENDSTOP_PULLUP_Z_MAX false
    #define ENDSTOP_Z_MAX_INVERTING false
    #define MIN_HARDWARE_ENDSTOP_Z false

    #define min_software_endstop_x false
    #define min_software_endstop_y false
    #define min_software_endstop_z false
    #define max_software_endstop_x true
    #define max_software_endstop_y true
    #define max_software_endstop_z true

    Thanks,  so  both cases are equal for autoleveling probe as Z-Min without Z-Max endstop? I am little confused, I cant understand the basic principle...
  • Posts: 0
    No one is max homing and z probing and case 2 is min homing with z probe and z probing without z max endstop.

    The problem as said might appear from having min and max endstops the same time with min endstop being a z probe in reality.

    OK, thanks!

    Now endstops m119: x_min:L y_min:L Z-probe state:H but probe is off... (using case 2)

  • Posts: 34
    I changed Z_PROBE_ON_HIGH 0 (was 1), G32 OK, but prints still high - its lower, but not on Z :-(
  • Posts: 0
    If you say G32 ok includes that z height after probing? If not z probe height is wrong and that will always lead to wrong z when homing.

    Which case did you use?
  • Posts: 34
    I used case 2. I do not understand "includes that z height after probing?"

    it seems to give different data.
  • Posts: 0
    Data needs context to understand as I do not see what you have in reality.

    1. G32 is it at bottom after G1 Z0?
    2. G32 after print is useless as it removes old z. Better etst is test the important part
    G28
    G1 Z0
    what distance do you have then? That is the only important part.

    Also make sure ALWAYS_CHECK_ENDSTOPS 0 so z probe can hot prevent G1 from moving down.
  • Posts: 34
    G32, G1 Z0 is Z0 = m114 - 0.00

    Print - + cca 2.3 mm, but m114 says z 0.00

    #define ALWAYS_CHECK_ENDSTOPS 0

    Printer heats, but when heat is OK, go downs to "Z0" which is not real Z0... (+ 2,...mm).






  • edited April 24 Posts: 34
    Interesting is, that in the past, with using the recommended Z calibration, once the first layer was OK - but the other were +2.3 mm... then all the time the Z0 is Z0 + 2.3 mm
  • Posts: 0
    G32, G1 Z0 is Z0 = m114 - 0.00

    that is clear. Question is more if the real Z is also 0.

    Also you missed answer to 2. 

    We are starting at the basics not printing. I do not know what you all do in your printer code. If you have a G92 Z-2.3 it will shift 2.3mm up for example, so first check if manual commands do what they are supposed to do.
  • Posts: 34
    After print:
    G28
    G1 Z0
    it does nothing - it think it has z at 0
    G1 Z2 goes 2 up
    G1 Z-2 does nothing
    homing Z stops on 2.3 without probe trigger



  • edited April 24 Posts: 34
    g92 does nothing... (any parameter x, y, z)


  • Posts: 0
    G92 only influences commands issued later on.

    homing Z stops on 2.3 without probe trigger

    is a problem. It is configured so z min endstop is identical with with z probe, meaning if it triggers M119 shows z min AND z probe high (please verify). Homing has to go down until z probe triggers. There is no reason to stop before except cross talk but that would not happen every time same height. Is there any error message in log? sometimes it just stops because enabling probe is not possible at current position and you need to use homign order with preheat so you can set probing position. Then you should see xy move z probe activation, z home, up second z home, disable z probe go to xyz home position defined (which can also be > 0). How far do you come?
  • Posts: 34
    Stop before trigger: there is no message in the log. It just stops, no info in the log.

    Homing with preheat: I have never used this - how to activate? 
    I have found M109 S[temperature] ; set the extruder temp and wait - is that OK?

    M119 will test when back home. 
    Thanks!
  • Posts: 0
    In config tool you set homing order and 2 options are with preheat (which you set to 0°c) - these allow setting the homing position. 

    DO you have proper z length set? z homing only stops mid way if z length is too short so it never reaches then endstop. Here multiple 
    G28 Z0
    would at some point succeed or of course correct z length.

    RESUME: 
    now home Z gives real triggered Z0. 
    G28 Z0 works
    But still adds some height when printing.
    Do not know, what else to do. I also tried G92 after succesful home to Z0... :-(

    17:41:39.501 : endstops hit: x_min:L y_min:L Z-probe state:H

    Where is z_min ? 

    My printer with z min = z endstop returns

    endstops hit: x_min:L y_max:L z_min:L Z-probe state:L

    So I guess you have no z min endstop defined, so it is not following the right routine.

    Also G29 is not autoleveling. G32 S2 is!

    So now that you know G28 is at Z=0  what does G1 Z0 does? Does it move 2mm up? If not you should have a look into your gcode what command is causing the 2mm up then.

    now playing with g30 on different x/y. When almost on the odge opposite x/y home, G30 causes moving UP with error "could not activate z-probe offset due to coordinate constrains... why? almost all bed G30 is OK... because it could be over config set leveling x/y limits?

    "So now that you know G28 is at Z=0  what does G1 Z0 does?": G1 Z0 does nothing...

    I will check gcode now. Thanks.

    It seems that Z sometimes stops on 2mm level without triggering, but after G32 S2 it "recover" again and G1 Z0 functions correctly - it stops on trigger. This behavior is present in print everytime. 

    I tested Z-offset -1.5 mm on slicer, but then Z was 50 mm... really strange behavior.

    I changed firmware to 0.9.2.9, probe leveling function better, than Dev (same config.h). 

    Printing:
    Prusa Slicer - best result, but when printing, it goes into bed, probably - 2 mm :-) // dev goes + 2mm
    Slicer - good, goes + 2 mm
    Cura - bad, goes + 2 mm

    Frustrated... is it possible that MPX.3 board has failed?

    thnks

    Nothing sounds like it is a board issue.

     "could not activate z-probe offset due to coordinate constrains...

    yes you have a z probe offset and if that plus position goes outside official area you get this error since it is not possible. 0.92.9 just measures at wrong position insted - if that is better...

    Start gcode looks good and executing only this code whuld leave you on .2 mm above bed.

    Have you checked the missing z_min in M119 response whcih indicates that you do not have z min endstop officially configured?
  • Posts: 34
    Missing Z_min is peculiar, as I use the same config.h for dev and stable versions. Stable has z_min, dev not. I will double check again - I think sometimes the configuration tool alters some parameters if I switch dev and stable, so I rather edit config.h manually. Or tool alters the config, so I should have two separate configs?
    Thanks.

    Reinstalled DEV, setup new config with config tool, download complete new code.

    M119: endstops hit: x_min:L y_min:L z_min:L Z-probe state:L
    G32 S2 autoleveling
    G1 Z0 - test Z0 (OK)

    Print

    Print level: approx. +22 mm (!) G1 Z0 is on the same level... :-(

    But after emergency stop homing Z goes to Z0...
    Reset g92 Z0, then print again (now Z_min is still OK)
    In fact, after bed heating G1 Z5 F5000 - lift nozzle - waits for heating, then prints in the lift nozzle height - does not go down to the Z0.

    G-code:
    M190 S60 ; set bed temperature and wait for it to be reached
    M104 S200 ; set temperature
    G28 ; home all axes
    G1 Z5 F5000 ; lift nozzle

    M109 S200 ; set temperature and wait for it to be reached
    G21 ; set units to millimeters
    G90 ; use absolute coordinates
    M82 ; use absolute distances for extrusion
    G92 E0
    G1 Z-1.300 F7800.000 (why it should go to Z-1.3, but do nothing?) ***
    G1 E-5.00000 F2400.00000

    I experimented with changing board from MPX3 to RAMPS 1.4, but x/y movements didnt function well.
    Compiled completely new dev version, chcecked endstops, did G32 S2 autoleveling

    Old Z+2 printing level is still there. Homing Z sets the correct Z0...  The Z-1.3 was my mistake, was set in the slicer.

    So after all experimenting there is exact the same Z+2 print level as in the beginning, so I would gess it is something connected with the MPX board in the firmware setting... What do you think?

    See what you wrote:
    M119: endstops hit: x_min:L y_min:L z_min:L Z-probe state:L
    G32 S2 autoleveling
    G1 Z0 - test Z0 (OK)
    M119: endstops hit: x_min:L y_min:L z_min:L Z-probe state:H

    Do you see the error? Z probe changes here and z_min is now present but differs. That tells me that they are not using the same pin as required for your problem. You need both and most must always be in sync or config is wrong. It must be same pin and inversion, only then the special handling including z probe height while homing takes place.

    What I wonder is that homing and autoleveling work as you said and printing not. I mean printing is just homing and then it prints on that Z=0 level if you do not modify it with G92 or with slicers z correction.

    I see, the error (L/H) was caused by position of the probe - on the bed edge, so it did not triggered. I set up small y offset, and it is OK.

    You are right, I do not modify Z, it is 0 in slicer (checked all slicers in Repetier Host V2.0.0) but it still moves before print +2mm.

    Then I home x/y/z, everything works... G1 Z0 goes to Z0... peculiar.

    What I noticed, that SOMETIMES homing X also moves z a little up - maybe that 2mm... this is why I thought that the board is not working properly.

    What else to do?
