I believe the Z axis motor (NEMA17- 42-48mm) have a compression spring in them that can cause Z offset issues due to the compression and decompression tolerances. I saw someone mention recently that those type of motors are not really designed for mounting in that Z plane, the fix being the motor re-mounted next to the Z thread and it being coupled with a belt. Alternatively could mount the motor horizontally, and run the belt in the current path of the lead screw ("single belted Z config") Another issue could be the entire bed being supported by only 2 linear rods at the rear, this will mean a lot of deflection of the front of the bed, dependant on how rigid that bed frame is
I think it is as you said the bed being supported only at two points. I have an ender 5 Plus that is rock solid and pretty much the same gear but the bed is supported at all four corners. A design fault in the CR5 for sure.
We have one in the office, and yeah, pretty much having a hard time printing with PLA, but this thing prints ABS and Nylon with no problems at all. Though i need to open the top cover and keep the temperature low for pla (190-50), any higher than that, clog.
Hi, please don't you have a link to the replacement heatbreak you used instead of the nonsense they put there. I can't find a replacement that will fit the holes in the cart. Thank you very much for your answer

Hello, can you send the links to where you purchased the upgrades please? Thanks!
