How to load G-Code that was saved?

In the G-Code viewer I have a "save" button to save a successful slice.
But, I do not have a "Load" G-Code button.

Can I load old g-Code?

Sure you can. Use the load button in the top toolbar.

Ohh, Nice. Thank you.
Can I load bfb gcode too?

I have no bfb, but after all it is simple ascii code, so why not. The only question is will the preview work ok, which I can't say without knowing the difference.

I made a minimal test that does not give an error - but does not work.
I am not sure that the scale of the gcode objects is the same.

Ok, I see the difference.

Do you really have a bfb-printer or did you want to use KISSlicer only? You can preview bfb code if you enable "Show travel moves". The host doesn't see them es Print moves because the bfb-printer have to extrusion per move, only a constant extrude speed. So in the code the extruder motor is only set to a speed.

Normal RepRap Printer use different firmware and need 5D - absolute E set in KISSlicer to generate usable G-Code. You find this in the GCode tab. In the extruder tab set mm/rev to 1 and Axis to E. With these settings you will get the correct preview in the host if you position it right. Your object was around the origin.

First, thank you - I can see the bfb gcode.
Could I move the gcode in the pring table?

Sure you can move it. After homing redefine position like this

G28 X0 Y0 Z0
G92 X-100 Y-100
