Repetier firmware skipping first steps

Repetier firmware skipping first steps
December 15, 2014 08:44AM
When I run the attached short gcode program it skips the first approximately 50 steps but then carries on till the end correctly. The file is just to use the 3D printer as a pen plotter and mark out its own heated bed for etching. What is plotted is a Hilbert curve and was produced with a spreadsheet. I think I have included all needed codes but there is something wrong.

Edit: Whoops! the version I attached here did not have the preamble. The one that I ran started with:

G21
G28
G90
M82
and the first G1 line ended with F500 to set the speed.

Thanks for any help you can give,

Mike

The problem has now gone away, leading to one of those "go figure" moments.

All I did was edit the original file with preamble to include 20 G1 movements in X only before it started. All of them executed. I then edited out only what I had put in and everything now works.

Somewhere between creating the file in LibreOffice Calc, saving it as a .csv, editing it with notepad, loading it into Repetier Host and saving it to SD some weird magic occured - but the good witch must have come along and made it better.
