GCODE opening sequence getting mad

[dd3d]

Does anyone knows why this common setup sequence gets my E180 mad?
The printer beeps and stops without printing when it receive this:
...

Code: Select all

G28
G21
G90
G92 E0

...
... then comes the printing code...

Thanks!

Hi,G28 refers to Auto-home one or more axes;
G21 refers to Set units to millimeters;
G90 refers to Absolute Positioning;
G92 refers to Set Position.
Can you provide specific action videos or code?
So that we can solve the problem better.

Thanks William,
Here you can find the first part of the crashing code, I have a small video but I can't post it here (extention type...)
Removing lines from 3 to 6 makes everything work.

Code: Select all

Hi, The M109 you provide for gcode refers to the time to wait for the hot end to heat up;
Have you tried printing other models?

Got it!

G21 is to blame.

I'll rewrite my startup sequence.
