Strange first layer problem with E2. one side of models

Postby FOGD.NO » Sat Jun 13, 2020 10:03 pm

Tried to print some hips and got a problem getting it to stick properly and adjusted offset up and down, flow, line width, magigoo and so on.
The strange thing was that I only had issue on one side. I thought it might be to hot and adjusted temp, but nothing helped. Brim came loose on one side, while other was fine. Almost like the line did not fuse together properly with a tiny gap between the lines. Only on one side, and I tried to turn the model and place it on different spots on the bed.
Then I gave up and used Pla with a different model to print. Noticed that my offset needed s small adjustment and when I checked the first layer it got the same issue. One side and bottom layers are good, but just after the seam and half the model only the shell/perimeter was not sticking together.
I now tried to change the Idesmaker slicer from latest Beta over to latest stable version instead since I thought it might be a slicer issue. I got the same problem with the stable version.

So what should I check next? I wonder if anyone else got an issue with it and perhaps many don't even notice since it is som tiny detail.
Could anyone else check? I got the same problem even with two different profiles, so I don't think it is something in my slicer settings.

Also it only happen if I have more then one perimeter on first layer. So if you set in slicer 1 perimeter/shell for the first layer it print perfectly.

I have the same problem with my E2.

Running Ideamaker 3.6.0 Beta
E2 Motion FW - 0.2.506

I don't know the E2 machine, but in my experience asymmetry usually indicates a cooling issue - where one side is getting more cooling than the other.

No. This is totally different. First layer only and only if you got more then one shell/perimeter. This is slicer/machine fault. Perhaps firmware

Could also be impacted by extruder calibration and z-offset.

On only one side of the perimeter only and in any orientation and any model and template? I tried different flow, Z offset, template, and different material. Also tried a new plate for my machine. Also two different machines in two totally different places got the excact same problem?

You should be able to get the perimeters to fuse by increasing the flow - going too far could create other problems, but turning that 'knob' should make a difference.

Not one side of the outer perimeteres. If I set single shell for first layer everything is perfect.

The bed is level and no problem if I fill the volume. But if I set more then one perimeter the outer perimeters are not closed just after the seam.

I hadn't noticed it was after the seam - try some extra restart. Since you don't have a gap you shouldn't need much to boost your output. If you're running a .4mm nozzle, .1mm or .2mm should be enough to notice a difference.

It is not the seam itself. Watch the youtube links. I know how to calibrate for print. I run 0.4 nozzle and I calibrated M572 for both type of filament. If it is 1 perimeter only it do not happen, but 2 or more it happen.

I understand. Do you know what extra restart is? Have you tried it to see if it makes a difference?

Sorry, but you are just wasting my time. If you don`t have an E2 to check if you also have the issue, then any of your "trying to help" don`t matter.
I have already checked with another E2 user and he got the same issue that rule out any slicer tuning.

If you're using M572 you could try stepping that up a bit to increase the initial nozzle pressure.
