Part of some of the trouble shooting I did involved changing the jerk and acceleration control. Do these values look correct or should I just uncheck the boxes? Ringing isn't something that bothers me either as most of my prints get sanded and primed anyway. I'm more concerned with being able to glue a couple pieces together more than worrying about a little ringing. I'm currently at 50 mm/sec for everything so I'm guessing that's too fast. Thanks.

Thanks for all the help. A reset of Cura connect seems to have reset the manual level height and that worked. Also changing the initial layer height to .2 has helped a ton. Since you were so helpful with that, I have one more small issue that I haven't been able to solve. I've had the UM3E for about 3 years. When I first got the printer, the corners were tight and sharp. Now, all my prints on the corners have a round bulge. Best way to explain it. It's hard to take a picture, but I've added them. I had a much worse issue, brought my printer in and they said they adjusted one of the larger rods as it was loose and moving and that helped a little bit, but I'm still getting it and it's getting difficult to make items that need to fit together. The first 2 pictures are a recent print and the wood filament one is the last print I got off the printer that didn't have rounded edges and I'm at a total loss of what it can be. I have tried to vary the following to see if it makes a difference and it does not. Layer Height, print speed, retraction, acceleration settings (jerk etc), different temperatures, different filament brands, different filament types, cleaned all rods and re oiled/greased, different print cores to make sure it wasn't wear, different wall thickness, different line width and all have had no effect. The only thing I can think of is that one of my linear rods has a small amount of play in the right hand side of the printer, but doesn't seem like enough to really do anything. I can't find any videos or articles on how to tighten those rods so that they no long have any play so I'm not sure if that's the issue either. Any advice or is this something I'll just have to put up with? I can start a new thread if you prefer to using this one. Thanks again for the huge help.

I have a print going right now but I will try all these when the print is done. Should be able to check all the things and get back to you tomorrow. In regards to the initial layer height, should I download a z addon for cura and change the z height? Printing some large higher detail items that are too large for my resin printer. If it's set as a default for .27 I can certainly adjust but I'd like to keep .1. Thanks again for the quick reply.

Thanks for the quick reply. I have not tried a cura connect reset yet, didn't think that would affect the bed level. When I do a manual level I follow the onscreen instructions. I do not have a z offset plug in. If I try and do a manual bed level, the print is a good 4 to 5 mm off the bed and that's right after I did a new level. When I do an auto bed level I need to adjust all the screws by about a quarter turn to pull the bed away. If I don't, the nozzle is so close that nothing at all comes out of the nozzle, but the prime blob is working so I know the extruder works. I print with a skirt, I rarely use a brim unless I have to for a large print. I don't tend to have issues with adhesion. I don't really know what I'm looking at when I look at the raw GCODE but here is the gcode for one of the most recent prints that I had to manually adjust the bed for. ;START_OF_HEADER ;HEADER_VERSION:0.1 ;FLAVOR:Griffin ;GENERATOR.NAME:Cura_SteamEngine ;GENERATOR.VERSION:4.4.1 ;GENERATOR.BUILD_DATE:2019-12-23 ;TARGET_MACHINE.NAME:Ultimaker 3 Extended ;EXTRUDER_TRAIN.0.INITIAL_TEMPERATURE:220 ;EXTRUDER_TRAIN.0.MATERIAL.VOLUME_USED:25627 ;EXTRUDER_TRAIN.0.MATERIAL.GUID:506c9f0d-e3aa-4bd4-b2d2-23e2425b1aa9 ;EXTRUDER_TRAIN.0.NOZZLE.DIAMETER:0.4 ;EXTRUDER_TRAIN.0.NOZZLE.NAME:AA 0.4 ;BUILD_PLATE.TYPE:glass ;BUILD_PLATE.INITIAL_TEMPERATURE:60 ;PRINT.TIME:38301 ;PRINT.GROUPS:1 ;PRINT.SIZE.MIN.X:9 ;PRINT.SIZE.MIN.Y:6 ;PRINT.SIZE.MIN.Z:0.1 ;PRINT.SIZE.MAX.X:170.206 ;PRINT.SIZE.MAX.Y:161.075 ;PRINT.SIZE.MAX.Z:4.5 ;END_OF_HEADER ;Generated with Cura_SteamEngine 4.4.1 T0 M82 ;absolute extrusion mode G92 E0 M109 S220 G0 F15000 X9 Y6 Z2 G280 G1 F2700 E-5.5 ;LAYER_COUNT:56 ;LAYER:0 M107 M204 S313 M205 X10 Y10 G0 F4333.3 X77.088 Y71.633 Z0.1 ;TYPE:SKIRT G1 F1800 E0 G1 F780 X78.057 Y70.618 E0.01056 G1 X78.152 Y70.523 E0.01157 G1 X79.165 Y69.546 E0.02216 G1 X79.206 Y69.507 E0.02258 G1 X79.657 Y69.087 E0.02722 G1 X79.761 Y68.994 E0.02827 G1 X81.055 Y67.889 E0.04107 G1 X81.067 Y67.879 E0.04119 I have checked all the wires in the back of the print head and the red wire for the bed level is working. When I run a diagnostic on the bed level sensor it says it's working good.

Has there been an update to this issue? I've been having the same issue. If I use auto leveling it will push the nozzle into the print bed and every time it levels I need to manually adjust all the set screws by at least a quarter turn. If I say to never use auto leveling the prints will start 4 or 5 mm above the print bed even after doing a manual level using the card to measure the distance to the build plate. My plate is original and in good condition. Anytime I change a core or at least once a week I have to manually adjust all the screws after it does an auto level. I'm using the most current firmware as of Feb 25 2020. Really need to resolve this issue and I'd like more info. I can send log files if that would help.
