Best settings for stepper motors ?
-
Looks like quite a bit of over extrusion also, could be catching an edge.

M350 X16 Y16 E16 I1 ; Set 16x microstepping with interpolation
M92 X80 Y80 Z80 ; Set axis steps/mm
M906 X1000 Y1000 Z1000 E800 I60 ; Set motor currents (mA) and increase idle current to 60%
M201 X1000 Y1000 Z1000 E1000 ; Accelerations (mm/s^2)
M203 X20000 Y20000 Z20000 E3600 ; Maximum speeds (mm/min)
M566 X1200 Y1200 Z1200 E1200 ; Maximum instant speed changes mm/minute -
Do you have an E setting for M92 in your config file?
-
Ok I see you do further down. Scrap that!
-
Have you checked your esteps?
-
You don't appear to have set a Microstepping for your Z Axis in the M350 line not sure if this would cause it or not TBH but worth a try?
-
M350 what do i put in this line ? i did make not any changes here .

If you don't have a M350 command then it defaults to 16x microstepping with interpolation to 256x, which is what most people use.
I think it's a combination of over-extrusion as Tim pointed out, causing the nozzle to snag on the print, and insufficient motor current.
You have your extruder steps/mm set to 663, which is about right for the RepRap Mini Geared Extruder (which has a gear ratio of around 5:1) but too high for most other extruders. So I repeat idevelo's question: have you calibrated your extruder steps/mm?
Also I suggest you increase the XYZ motor current to 1300mA (M906 command in config.g).

ok i give a trie to change motors to 1300 and extruder to 663

I am manegd to print the lizard.gcode my tower are on 1000mA extruder 800mA
extruder steps/mm set to 500 . printhead E3D volcano 0,8mm
only issue i have was the temp. setting in the lizard gcode was set too low , i had continues put it back To 210° els it would not stick to my buildtac heatbed .see video :
