I purchased Gulf Coast Robotics Modular 3-Point Y Carriage. it worked great but i bought another ender 3 pro and when i installed it on this one it hits that Y axis stepper motor bracket. Im wondering if anyone has or knows of a bracket that can help me with this or some other solution.
I can't help with a fix. but I can tell you that the late 2021 (July) models of the E3P are different from previous models.
Extruder arm, rail & distance clearances have changed. That's why you're having carriage issues.
Until 3rd party sellers catch up, you might have to wait it out.
I looked at an older E3P side by side with my newer E3P & noticed that the bed bolts/nuts are reversed. This will definitely cause clearance issues.
