A1 Build Plate Aligner

1/26/2026 update: u/Flyrockets informed me of an error that is occurring on Firmware 01.01.50.24 (beta tester firmware) that the nozzle will hit the build plate aligner after the third layer and cause an error, causing the print to stop. I have updated this design to lower the aligner to be 0.5mm above the Textured PEI build plate vs the 3mm it was previously. This shouldn't cause any errors as the third layer should be over 0.5mm in most cases, but I do not have the 01.01.50.24 firmware to confirm. Please let me know if you experience any errors while using this updated design and I will update it again. To easily remove your build plate aligner and update to the new one, remove the old build plate aligner starting with the lober side and simply push it down and off the heat bed.
