Extended Z-homing spacer for early/preorder versions of Elegoo Saturn

thingiverse

Update: Apparently on newer versions of this printer, there is almost no space between the homing arm and the Z-rail. The solution is to print and mount this little standoff/spacer where the arm attaches to the Z-axis: https://www.thingiverse.com/thing:4797527 ------------------------------------------------------------------------------------------------------------ This thing press-fits onto the end of the stock Z-homing trigger on the Elegoo Saturn, extending it by 2.5 mm. This causes the plate to stop that far above the screen when homing. This enables you to install magnetic flex plates which add thickness to your build surface, without the plate crashing into your screen when it homes. IMPORTANT: The first time you install this, remove the vat and plate entirely. Home the machine. Now check if the build plate (with your flex plate installed) will slide on and clear the screen. If it does, continue and use this part. If not, your flex solution may be too thick, and you'll need an even longer z-trigger than this to avoid crashes into your screen at the beginning of a print. This was developed and tested working with the Wham Resin flex plate solution from Wham Bam Systems, on an early production Elegoo Saturn. I strongly recommend you print this in the provided orientation, with an opaque resin to reduce light bleed into the slot. The slot dimension is critical to providing a good friction fit. I also strongly recommend that after testing and just before final installation, you put a dab of CA glue or other adhesive in the slot to keep the spacer from shifting or falling off. https://whambamsystems.com/fbs-for-resin
