I bought an Ender 3 Pro about 2 years ago as a backup and am finally putting it together. The problem that I’m having is this. I got the Z gantry to be perfectly level with the top bar. But it’s not level with the bed when I have the bed leveling knobs all turned as far as they will go on way. I don’t know if this will pose problems for me, so I don’t want to finish assembling it until I know. I got the gantry level with the top bar by turning the eccentric nuts on it’s guide wheels. But as I said, when I turn all the bed leveling knobs to their stops it’s off level by about 3mm. If anyone could give me some guidance it would be much appreciated. Thanks.
