Hi
I just start to print some basic of Gcode
after I preheat ABS 200 C and run the system to print
as the image I saw some ABS in white-blue color on the Bed.
but after many minute - hour .
I can't see any change form that layer. My question
1. I have something wrong assembly ?
2. How I can check the extruder moter is Ok or not ( like G-code command to rotate it )
I try to click the extruder command in software but I can't see any change after click them

Thank in advance

You should raise the temperature to 235-240 degrees.

Thank sir
I increse temp extruder as your recommend .
it can melt ABS
but I think my feed motor must have something problem
I try to click feed when temperature correct but I can't see anything happen
When I send print command i still nothing forming like old image that i post

Do you have any suggest ?
Thank you

Maybe the distance between the nozzle an hot bed is too low to let the filament come out. Try to adjust it.

I have the same extruder and I had to rotate the trimpot on the driver board for the extruder. About a half turn from where it was by default. Also make sure you loosen off the bolt holding that tightening bracket up a bit for abs printing.

Thank All
After I trial an check again with my assembly
I found
1. I install chip A4988 of Extruder in wrong direction
2. I set Z-axis too low
3. I put the wrong parameter in Repetier
After I fix , Extruder can run and everything look better
Now I can print
^^

Thank you again
