I don't have access to a SnapMaker A350, so I cannot help you with the values to use, but I can help you with the what to meassure.

 

The X min value is the horizontal distance between the left side of the printhead and the tip of the nozzle.

The Y min value is the horizontal distance between the front of the printhead and the tip of the nozzle.

The X max value is the horizontal distance between the right side of the printhead and the tip of the nozzle.

The Y max value is the horizontal distance between the rear of the printhead and the tip of the nozzle.

 

The gantry height is the vertical distance between the buildplate and the bottom of the horizontal extrusion the head moves over when the nozzle touches the buildplate.

 

Each of these 5 values is only used when you print in "one at a time" mode. If you don't use that mode, the values you enter here are not critical.

Thanks.  That last one is still somewhat confusing.
I think it means that if the head is all the way down, so the nozzle is just touching the build plate, the distance between the build plate and the Gantry that supports the print head, correct?
hmm, on a SnapMaker, the Gantry is behind the printhead, not above it.
Might that be a problem?

Yeah, I probably won't use the One-At-A-Time mode, but I'd still like to have the values correct.

    And I just figured out why it won't let me change the values.
    On my PC, the "-" char is being displayed as a blank, so I didn't realize you had to enter the values as negative.
    That is a WEIRD bug.

    Yeah, it's a bug that is scheduled for our current sprint, so it should be fixed for the next release (4.5) if all goes well.

    Here is the Snapmaker 1 settings, the printhead would be similar I guess on the Snapmaker 2.

    These are the ones I finally ended up with for the SnapMaker A350.  Though I'm probably going to drop the "G28" from the Start code - as the SnapMaker does a quick calibration on every print and leaves the head in a known location.

    Thanks for sharing, this will be very useful when my printer arrives.

    It appears (at least on Mac), the printhead settings are still stuck at -20 and -10.  Any ideas how to fix it?

    The problem with it not accepting positive numbers (it will accept "0")for printhead settings remains in both Cura 4.5 and the 4.6 beta in Win10.

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
