Hello , I’m wondering what could be the cause of this first layer rippling I tried recalibration on the extruder and changing the exstruder temperature from 200 to 195 to 190 and I’m still having this issue. Any help with this would be greatly appreciated.
You got the first layer too close to the printbed. With 0.1mm more may be enough
Humidity in filament, bed too hot or printing the first layer too high. I had similar effect. I solved first layer adhesion with elmers glue on cold glass, eva dry to dry up the filamant, and a long feel gauge kit for leveling the bed.
If it was humidity In the filament wouldn’t it affect the rest of the print ? I tried messing with the z offset and had the same results it only seems to be happening on the longer runs.
I have the same problem a few months ago, after some tests , for me the solution was to get the nozzle away from the print bed. Another thing I saw is that the PLA has a greater chance of experiencing this problem.
When printing the first layer, does it stay flat, or does it looks like it wants to curl up ?
Looks like poor adhesion to the bed. Try adjusting parameter related to the first layer like:
- cleaning wax off tape (sand paper, alcohol)
- different tape
- verify Z axis homing
- increase first layer height
- change print bed temp
- ensure fan is off during first layer
Etc.
It curls up like in the picture, I’m going to try turning the fan off for the first layer.
My fan is always off for the first layer. And indeed, it still can be poor adhesion (see my comments about Elmer’s on cold glass) and or bed offset.
If it’s abs capton tape would help, but simple enough to buy styrene liquid and melt abs for first layer adhesion
What about if the first layer height doesn’t match the extrusion rate? Over extruding slightly?
Extruder fan (the one blowing to your extruded part) should be on, since if you used melted abs wouldn’t be much of a problem on 1st layer adhesion (dried out brushed thin layer of melted abs) or perhaps you set your bed level just a little over tightly against your extruder nozzle end
Maybe raise the speed on over extrusion?
I had this problem before as well. Check your Z height first. If it is not that then your filament has absorbed too much water and you need to dry it out. You should store it in a sealed box with some DRY silica gel.
That’s a nice field tile for Catan.
Thanks I made a whole board and hand painted them.
So if it’s a filament moisture issue wouldn’t it effect the rest of the part ?
it has to be you Z height, you head is not “planted” down enough to squish the first layer down. I usually work with .25 mm layer thickness. I do adjust my nozzle at .25 mm from the bed with a feel gauge.
Then, I set the first layer to be 110-120% of the defined layer thickness. This means there will be more plastic extruded and the first layer will be thicker, more firmly planted if you would.
