I’ve seen a number of threads on this issue but I have been unsuccessful in fixing my problem.
The problem is, the BLTouch auto-leveling reads that the left side is about 0.4 mm higher than the center and ~0.2mm too low on the right side. Predictably, a test print reveals that nothing sticks on the left but is really squished close on the right.
I read this topic The left side is too close, the right side is too high (or the contrary) which makes me believe that my printer is not square. Unfortunately it doesn’t mention any method to actually square it so I have no idea if it’s done right. I used a speed square to ensure the towers are square with my table (along the x axis), and then I used it to ensure they’re 90 degrees in respect to the frame (along the y axis).
I do have the Gulfcoast Robotics Z-brace (https://www.amazon.com/Gulfcoast-Robotics-Z-Brace-Duplicator-Printers/dp/B07B3X1XH8) and I used it to square the towers perfectly along the y axis.
Also, I used these bars to ensure the x-axis is level (https://www.thingiverse.com/thing:1138928).
Any help would be greatly appreciated. I’m running out of hairs to pull out
