[FIXED] Issues with nozzle scarring the bed prior to first extrusion

Am new to 3D printing and am struggling to produce anything worthwhile.
Just started using simplify 3D, imported an object, selected my settings and exported to a gcode file.
Problem is when I start the print process the nozzle homes then proceeds to grind its way along the x axis..
I have to stop it quick as the nozzle is really scratching the surface..
The bed is level and I have no problems when using Cura with the same gcode..
Any suggestions

Can you share your factory file or G-Code? What printer are you using?

You said your bed is level, did you level by moving the extruder to all four corners?

Hi all..
The bed was leveled using the paper method in all corners.. I don't think this is to do with how level the print bed is.. using other software I have had some small success..
The gcode file generated by Simplify 3D is attached
The starting script is as follows
Code: Select all
G28 ; home all axes
G1 Z15 F4000 ; lift to avoid binder clips
G1 X150 Y20 F7000 ; go to front of bed
G1 Z0.1 ; use the bed to block the nozzle to prevent ooze
G92 E0 ; zero the extruder
G1 E3 F50 ; Make a blob / Prime nozzle
G1 X100 F4000 ; wipe along the edge of the bed
G1 Y5 F4000 ; wipe along the edge of the bed
G1 X200 F4000 ; wipe along the edge of the bed
G1 Z0.5 ; lift before move to center
Thanks for your help..

I am having the same problem. The G28 home command is forcing the ejector to high on the z axis and impacting the pad. I have tried to change this under the General Options/Machine Origin offset but it made not difference. Also, tried to change the Z-Axis Global G0Code Offsets in the FFF Settings which did not help either. Have used Repetier and did not have this problem. So why is Simplify having an issue. Very frustrating. How do we tell Simply3D where the Z home position should be????
Loop.

I’m happy to state that this issue should be resolved now in the latest 4.1.0 release. Our team successfully tested the factory file from
viewtopic.php?f=9&t=9109. Layer changes now feature Z moves prior to X Y moves. This was just one of many improvements to the software. All of which are detailed on our
Release Notes page.
Thank you for your help reporting this issue!
