My delta forgot how to delta - 4th axis
-
I trying to change my delta configuration to add a flying extruder 4th axis located at (0, 0). After changing what I believe is necessary, with the wiki as a guide, I get console messages notifying that "Homing file homeu.g not found". I understand homing the U=axis should be included in homedelta.g. Futhermore, the U-axis never does not follow the head as expected (remain homed).
What am I doing wrong?

AFAIK homeu.g would (normally) only be called if homeall.g didn't either sucessfully hit an endstop with G1 S1 Unn (or S3?) or a G92 Unn command was encountered.

homeu.g
Tried creating an empty homeu.g?
That eliminated the error, but not it's cause I believe. AFAIK the firmware should not even be looking for a homeu.g

In delta config's, there is no homeall.g, only a homedelta.g. During home the U-endstop is correctly triggered.

Adding G92 U0 (or U what-ever-the-correct-value-is) after the G1 might be worth a try to see if it still wants to call homeu.g

I cannot manually set the position with G92 as the position changes after each auto-calibration run and is thus not known 'at compile time' for the home file.

Even 0 or an approximate value will allow you to test if the problem is the firmware not thinking the U axis is homed by the end of homeall.g/homedelta.g. Sounds like there is either a config issue or a firmware bug.

Is there anything odd in your config-override.g?

Which firmware version are you running? You need 2.03 or 3.0 beta to support additional delta axes.

I feel embarrassed now, I forgot there's an M665 in there, doh. Stuff works as expected now.
