MatterControl 2.0 Z Offset?



  • We just upgraded to the 2.0 Mattercontrol and I cannot find the Z offset window so I can adjust it.
    Can someone please let me know where I can find it on the new version? Thank you.



  • Hey @NCC

    You will find the Z-Offset in the "Printer" tab under General.

  • MatterHackers

    You make the printer tab visible by going to the overflow menu and selecting 'Configure Printer'

  • @michael-petitclerc It is missing in the latest release.



  • Well, I just looked on my Home computer and you are right. It is still on version 2.19.1.10116 But when upgraded to latest stable version 2.19.2.10157 It is NO WHERE TO BE FOUND>

    This setting has been migrated to the extruder Nozzle Offsets. It should have automatically moved your setting there and continued to work. You can use the setting from there, but you should note the sign has been inverted.

    Hope this helps.

    You could also enable print leveling and that will automatically compensate for any z discrepancy (and any leveling issues you may have). This would not require modifying the z offset at all.



  • "The sign has been inverted"????? That would explain why my nozzle went through my glass bed last night. I have done a 3 point leveling at least 4 times and it still does not even come close but pushes the bed down and will not extrude. Is this inverted as well?
    Unfortunately I've used MC ever since I got my A8. This is the first time I've had ANY issue like this. Printing has completely ceased. I'm uninstalling and trying the earlier version. Hopefully my settings will still be there. I look forward to using MC again instead of learning something completely new.
    I'm following this chat so Please let me know when the update has been posted.



  • @hardcoremidget One more note. I did find the nozzle offsets but when I hover over it there is a notation that this is for E1 and dual nozzle offsets. That this may not be applicable to all machine. It determines the offset relative to E0. Not the offset OF E0..
    However Lars is correct. It will offset the nozzle of E0 higher if you use a Negative number.llllll



  • Well, just found this on Wiki.

    Tips for setting up your printer
    Mechanical Changes:
    Automatic Print Leveling works better if your limit switch is on the top (Zmax). We’ve gotten it to work on printers with the z switch on the bottom (Zmin), but it’s a little tricky.

    G-Code Changes:
    If the limit switch is on the bottom (printer homes to the bed). Add the following G-code after homing.

    G1 Z1 ; raise the extruder to be 1 millimeters above the bed.

    This code will help prevent the extruder from bumping into the build plate when it first starts moving.

    As of today, I still cannot get Print leveling to work correctly on my A8.



  • Hey @HardcoreMidget

    So at the moment both Lars and I will not know how to help you, to help you out we are going to need you to provide information to us. I see the issue is that the nozzle is touching the bed but what is the set up of the printer? Do you have a BL touch installed in the printer, if so have you calculated the offset from the probe to the nozzle and applied that value in MatterControl?

    I presume from you linking the Z-Endstop information that the AnetA8 has the home switch at the base of the printer so the nozzle homes to the bed? If you could clarify this for me I can see how we can set you up.



  • @michael-petitclerc Thank you Michael, Generic A8 with 4 corner bed adjustment, No BLTouch. Z stop is at bottom and homes there. I have added the Z= -1.25 to the Extruder offset and that seems to be working. I'm assuming it has to be a negative since It's referring to the Top of the Z position even though 0 is at the bottom.
    I've repeatedly done the 3 point Leveling with Leveling on and turned leveling on after doing Leveling but it makes no change to the Z position as it moves across the bed so I don't think the Leveling is active. I've also Re-Sliced it after Leveling The leveling shows the nozzle touch position + paper at .119, .119 front and .126 back. Am I correct in assuming that the Z position should change by those differences as the nozzle moves across the bed? That does not happen from watching the Z position on the screen and printer.



  • You would be right that our nozzle offset from the bed is calculated from the top because of how our Pulse printer is set up. (Unless I am wrong and Lars drops in to tell me otherwise ;D)

    I believe that if you input values for bed leveling in MatterControl then you should see the Z height adjust mid print to compensate. I am not sure if there is a significant range it needs to meet to actually apply an adjustment but you should see it. An easy way of seeing it is to run a print with raft and the interface layer from part to raft will easily show the compensation on larger parts. Only down side to this test is that you need to enable raft.
