AHHHHG!

Calibrated in... Followed setup (as far as I can tell) Ran test cube job.
now the head crashes into to bed.

Even my scripts do now.

Only thing that I can see that is different is my XY translation I had to set to zero so that it is in the middle of the bed. (gene's pic shows 280)

Which, I am sure that once I resolve this, I will have to recalibrate then?

By Pushing G0 z50 F3500 that puts it about 1mm above the glass.

What the heck did I do?

XYZ Max Length 357.381

Just had a thought... Steps per mm?

steps per mm was the first thing that came to mind.

If the travel across X and Y is "level" and parallel to the bed, you should only need to make sure steps per is correct and set the X, Y and Z length in the firmware or EEPROM.

That is all I can think of too... Thanks for confirming it.

but, strange that I had it working all throughout the Calibration. I think I only changed the extruder steps/mm.

mmmm SOoooooo Close! I am not at my machine at the moment. 12 hours to go... tick tock tick tock tick tock....

Ok, I did set the wrong Steps per mm wrong.

the new firmware has a one that is not explicit to the extruder.
a setting that I do not see in some of the settings posted by other users. (( I am unaware of their build number, so this may have been around for a while))

Any Idea what it is supposed to be set at?
