Hi
I have a Anet A8, with Bowden E3D v6.
I´m printing at 225c and with 30mm/s.
Using PLA - Transparent
I have a consistent problem with my prints.
My problem is that I get errors in my prints on layers that starts around 130 mm and above.
I hope I can post some pictures below.
Appriciate all the help I can get
That’s a difficult print to do at the best of times and will test your printer and knowledge to the max.
It looks like a problem with your slicer. Have you tried vase mode?
225 seems a little hot for pla first of all. if pla doesn’t extrude right at 190-200 there probably is a problem with your nozzle getting clogged. try lowering your temps.
about the machine lag though… this can be caused by a number of things. I suspect the sd card that comes with the printer is cheap and low quality, I suspect it for ruining a couple of my early prints. if you use the sd card to print, try printing over usb using your computer. if you have been printing over usb, the problem could be a faulty usb cable. I notice the print stops and jumps when my pc is lagging but doesn’t skip instructions which indicates you may have a communication problem.
somewhere there is a communication error, try swapping your printing method (USB <–> SD). if you have been printing over usb, try enabling TCP steaming mode. If usb printing is unavailable to you, I suspect a higher quality sd card may be a solution for you.
Looks like the shell thickness is thinner than your extrusion width. Different slicers will handle this differently (like extruding dots instead of a line) but getting it right usually means manual adjustments. I use slic3r because it gives me the most freedom and control. I would need to see the design or gcode to give any more advice.
I think you need lower temperature ~ 210-215. try it.

Hi and thanks.
No I have not, I´m still a newbie to this
I will give it a try.
Do you have the stamina to explain to me what vase mode is good for?
Or can you point me to a good explaining site so i can brush up on my knowledge?
Thanks again // Christer

yeah, I agree 225 is high.
I did a test this morning and increased the temp to 230 and the error started just after a couple of layers.
So tomorrow i will lower the temp and give it another go.
I usual print at 195-200 with other models but since this is a thin airplane fuselage and the instructions (recommendations) from the guys at 3dLabPrint said 230 I insisted on trying at 225.
Let´s just hope that the layer will adhere properly at around 200.
Usually I print through USB, and actually now that you mention it, I have not had a problem with that. Started to try out SD-card recently, and I do use a better quality card.
I will go back and try with USB again, thanks for the tips!

yep! As a answered in an earlier reply I tried to increase the temp as a experiment and it got worse. i will try to lower it tomorrow, I´m just afraid that the layers won´t bond properly at around 210.
Thanks for your input! // Christer
There could be multiple reasons.
Your cables might be strechted at this height. Make sure all your connectors are tight.
Extrusion motor could be overheated after a certain time resulting in it shutting down for small periods to cool itself.
Your Z axes might have problems. Make sure they are clean. There can’t be left over burrs or dust in the thread of the Z axes.
Make sure both your Z axes are parallel. Make sure both your Z axes are straight (no bends!).
These are just some possible causes from the top of my head. There could be many more. It looks very unusual to me though. I would try making a print with a similar height.
