I have started using my k8200 today, and im running into some minor issues.
The PLA filament sticks very poorly to the default printing bed, even though I thoroughly degreased it using warm ammonium. I have learned that that distance between extruder and heating bed must near be perfect or else the extruder will pull off the poor sticking filament or when it is to high the filament wont stick at all. A corner is a littlebit curling upward, but it is minor. Despite my current attempt is going very well ATM (im at layer 2 or 3), the extruder still pulled some filament and I had to remove it. But attempt #8 or #9 looks well so far. I think I will finally get a decent product out of it.
When I first started a week ago with my first trial, the extruder wasn’t strong enough to pull the 3mm fat PLA through. I was helping the main sprocket with hand when I suddenly figured… I am not doing this for 3:40 hour… So I figured I could tune up the protentio
Sometimes the printer loses were it is, and starts printing on the wrong spots. I tweaked the potentiometer of the stepper drivers a bit up, it seems I have fixed this issue. One time I accidently moved the 3D object in repetier and the printer didnt hesitate 1 second and did the same -_-"
I have one question. My printer didn’t came with a glass plate. I have read a review which said that I should get one, and spray it with taft extra strong hair spray. Now my filament sticks quite poorly this seems very plausible.
So will that hairspray covered glass solve the poor sticking filament issue? (can I spray the hairspray on my current printbed as well).
And another question. What is easier to print ABS or PLA. I bought 1kg PLA so I will use this before I buy new filament. I’m down for the easiest
and last. If I would want to print a piramid, upside down. What is the steepest angle that I can print?
And now, while typing this, at layer 4 my entire print came lose -_-* FML…
Set all of the voltages to 0.55 this works best.
Do not go over 0.6 the drivers will over heat and do some weird stuff.
PLA is easier to print with Just my thought.
I use hairspray on my bed first layer 50C all others 60C
You could use a piece of printer paper fold it over so you have 2 layers.
Find the high spot of the bed (none of them are perfect) and calibrate the Z axis.
I set the hot end to 190C.
This should be a good starting point.
You can tweak it from there.

I know use double folded printer paper, I attached it with scotch tape on my printerbed. It seems to work well. I guess it will be payne to separate the object from the paper I didn’t even calibrated the Z axis, didn’t had to. I am now printing the clips to mount the glassplate which I will get on Friday. After this I will print the cover the for the PCB which I tried about 10 times now XD. Tnx for the advice
I only dont understand this sentence: “I use hairspray on my bed first layer 50C all others 60C” what do you mean with all others 60C, do I have to increase the bed temperature to 60C after the first layer has been printed?? Can I do this during a task?
I think you did not understand.
Use the folded paper to calibrate the Z axis.
You fold it and set the Z end stop do not leave it on the bed.
In the slicer software press the configure button click on the Filament and settings tab.
In there you will see Temperature for the extruder and bed.
I have the bed set 50C first layer and 60C for all others.
Clean you bed with alcohol then spray a light coat of hair spray on it.
This will help your project stick to the bed.
If you didn’t calibrate the Z axis then that would be the reason nothing is sticking to the bed.
I use a bit of PVA (wood glue) mixed with water on glass plate.
It works everytime with PLA for me. And it’s easy to remove the object when the bed is cool.
Maybe it works without glass plate I have not tried that.
