hi guys
it is my first 3D printing experince …
the problem is first layer of printing is good but then every thing is a mess
any ideas please help
Which filament are you using? PLA or ABS
What is the temperature of the extruder?
What speed have the X and Y slide?
I suppose you use the software from the velleman website?
i am using the default every thing which came with the printer and i installed the velleman k8200 program
and it always start good at the first layer then it print the rest in an wrong position …
if you can help me with a code that i can send to printer to set the eeprom it will be fantastic thanks in advance
If You use the printer for the first time, then move the axis from the manual control in reptier.
And check that the movement of X/Y/Z is indeed the distance of the selected movement.
Check also distance of the zero position of the Z-axis towards the heated bed.
keep also an eye on the straightness of the heatbed.
If the heatbed is not flat enough, then the printed result will fail when printing larger parts.
Small parts may work but larger not cause the distance between nozzle and heatbed will get bigger towards the edges for example.
A glass plate can solve this.
Also, check that the first layers are indeed sticking to the heatbed cause when they get loose from the heatbed, it will ruin the model.
Extruder temperature is … very … important related to the used filament, also heatbed temperature and unfortunately Velleman has made
a flaw with the design, it can not heat up the heatplate enough for ABS, in fact just enough for printing PLA.
So describe you entire setup related to deviations of X/Y/Z movement, Z-axis zero position correct alligned, heatbed flat enough, temperature of the extruder when printing PLA (from 190°C)
and temperature of heatbed.
A 3D printer is not as a inktjet or laser, plug it in and print;
It needs always user intervention, even with 3D FFM printers > 2000 euro.
When you set the reference voltage on the stepper drivers you need to set the to 0.55
Do not go over 0.6 this can make them over heat and really do strange things.
Out of the box they are set to 0.8 if you did not set them this may be the problem.
