Delta printer calibration with V1.0dev

kaskas
in Repetier-Firmware

 Hi Repetier,

Spent two days trying to solve this problem, ...now completely lost  :/

I just upgraded from .92 to 1.0.0dev version and recalibrated my delta printer using
https://www.repetier.com/documentation/repetier-firmware/z-probing/   
 - M321 S2
 - G28
 - G131
 - M99 X0, M99 Y0, M99 Z0
 - G132 S1
 - M320 S2
 - G32 S2

Calibration is OK except the area opposite to A tower
in this zone, the extruder is 0.25mm over the plate


I tested my glass bed (D200mm) and it is not warped, so I shouldn't use G33


Is there a setting to raise/lower a specific region of the bed
Kindly let me know what I am doing wrong
TIA

    Most likely changing b or c angle will help here. But that alo has an effect on the other sectors, so be carefull. Normally only very small changes like 0.1-0.3are needed. G33 would also help here if you do not manage to optimize geometry further.

     Thanks for your for your prompt response

    >> changing b or c angle will help here

    Just to make sure, are you referring to Alpha A, Alpha B and Alpha C parameters ??

    Considering the specific area to trim, which angle should I try to adjust first ??

    You are doing a great job by the way  :)

  • RepetierRepetier
    Yes these angles I mean. Maybe think like having a circle with 3 bars below. If you move the bars one side of the bar goes up and the other down. But in the end it is try and error. Make a height map with repetier-host, store it as table over clipboard, change angles and repeat. You will see what changes in which direction and after a few iterations you hopefully have a better setting.

    That did the trick, thanks  :)

    My new setup:
     Alpha A  210.500
     Alpha B  329.500
     Alpha C   90.500


    This is my Delta printer calibration workflow:
     - M322 S3         Reset auto level matrix permanently
     - G33 R0           Delete distortion map
     - G28                 Home
     - G131               Remove any extruder offset
     - M99 X0,Y0,Z0   Adjust sliders using a stick
     - G132 S1          Measure tower endstop offsets & stores
     - M320 S2         Activate auto level permanently
     - G32 S2            3 mesures, fix rotation of bed & store
     - G33 S2            3 mesures, fix distorsion of bed & store
     - M323 S1 P1    Enable distortion correction permanently

    Is there any missing commands ??
    Is there any useless commands ??


    Finally 'Z-probe speed' EEPROM setting seems to have no effect on G32 & G33 process (was OK with V0.92)

    Thanks again for your help
    Is it possible to make donation using PayPal ??

    For donation suse this link:
    https://www.repetier.com/download-software/

    Note that
     - G131               Remove any extruder offset
     - M99 X0,Y0,Z0   Adjust sliders using a stick
     - G132 S1          Measure tower endstop offsets & stores 
    is normally only done once per printer unless you change endstops. No need to repeat this on recalibrations.

    Done  :)

    I was already on this page and didn't donate at that time because I only saw credit cards logos,
    and didn't want to enter my cards details
    I admit I was too lazy to read the whole text, but I may not have been the only one

    One suggestion: just add a PayPal logo to clear this matter

    I've apparently got something wrong, because when I enter M99 followed by X0, Y0, or Z0, the motors remain locked and Repetier Host (V2.1.3) logs a "Unknown command:N72 M0".  Not sure where the M0 is coming from.  Also, I can run G132, but if I add S1, it ignores the command.  Server 0.90.1 - PAN 56.  Firmware 1.0.2.  I just downloaded a fresh copy after going through the configuration tool.  I set "EPROM set" to 1.  I thought I remembered seeing it was supposed to be set to 0 to allow you to save, but 0 says, "eprom disabled" in the config tool.  

  • RepetierRepetier
    M99 does not contain a comma , just to be clear. It is you only use x0 or y0 or z0. That axis is then disabled for 10 seconds!
  • CulturedropoutCulturedropout
    No - I'm not using a comma.  But if I type, "M99X0" nothing happens - all the motors stay energized.  This used to work, so I'm not sure if there's an issue with the upgraded firmware, or what.  Is there a parameter or a define that needs to be done to enable this feature?
  • RepetierRepetier
    Please separate parameter with a space, not M99X0 but M99 X0.
