First layer

First layer. I'm attaching a PDF with my problems, solutions, and accessories. Sourced from Reddit https://www.reddit.com/r/AnycubicKobraS1/comments/1m2gizn/sharing_my_experience_after_1000h/ The 3mf file contains modifications to the printer profile. Change the purge line on the front; check if the first layer is not printing correctly; adjust the Z-axis offset. For the first test print, always use the offset at 0. If it sticks too much, increase it gradually, for example, by 0.01. If it doesn't stick, decrease it by -0.01. Profile modification you find: Lower the bed after printing is complete G-Code end {if max_layer_z < 150} G1 Z150 F1200 {endif} G92 E0 G1 E-2 F3000 {if max_layer_z < max_print_height-1}G1 Z{z_offset+min(max_layer_z+2, max_print_height)} F900 ; Move print head further up {endif}  G1 F12000; present print G1 X44; throw_position_x G1 Y270; throw_position_y M140 S0 ; turn off heatbed M104 S0 ; turn off temperature M106 P1 S0 ; turn off fan M106 P2 S0 M106 P3 S0 *{if max_layer_z < 150} *G1 Z150 F1200 *{endif} M84; disable motors           ; disable stepper motors -------------------------------------------------------- change of purge line from rear to front G-Code before the layer change G1 X158.17 Y0 F18000 G1 E-0.8 F2400 {if layer_num==0} ; PURGE LINE M204 P500 SET_VELOCITY_LIMIT SQUARE_CORNER_VELOCITY=9 G1 Z0.50 F900 ; for object exclusion *G1 X158.17 Y0 F18000 G1 Z0.25 F900 G1 E0.8 F2400 G1 E0.6 F2400 G1 F3000 G1 X227.64 Y0 E3.72454 G1 X227.64 Y0.45 E0.0252 G1 X158.17 Y0.45 E3.72454 G1 X158.17 Y0.02 E0.02305 G1 Z0.5 F600 *G1 E-0.8 F2400 {endif}
