Nozzle is burrying itself in the piece I just printed. Help.

Hello, guys.

 

I am having a little bit of a problem when finishing the printing.

 

It seems that when printing is done, the hot head tries to almost touch the bed (just like when you press the home button in ANET ET4 PRO).

That is causing the hot head trying to go through the piece it just printed.

That problem made clear when I printed a brigde test as the following shows:

The image above shows that the nozzle went through the column .

Other important info:

 

Start G-CODE: 

G92 E0 ; Reset Extruder

G28 ; Home all axes

G1 X0.5 Y20 Z0.3 F5000.0 ; Move to start position

G1 X0.5 Y200.0 Z0.3 F1500.0 E15 ; Draw the first line

G1 X0.8 Y200.0 Z0.3 F5000.0 ; Move to side a little

G1 X0.8 Y20 Z0.3 F1500.0 E30 ; Draw the second line

G92 E0 ; Reset Extruder

G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed

G1 X5 Y20 Z0.3 F5000.0 ; Move over to prevent blob squish

 

END G-CODE:

M140 S0

G92 E10

G1 E-10 F2000

G28 X Z

G1 Z200.0

M106 S0 ;Turn-off fan

M104 S0 ;Turn-off hotend

M140 S0 ;Turn-off bed

M84

 

Can someone help me solve this, please?

Your end gcode has a "G28 X Z". G28 tells the printer to home the specified axis and unless your printer uses the Z axis as something other than up and down movement you probably want to change Z to Y.
