PNCconf 7i92H and 7i76

He posted the hal/ini files a few posts ago

Does the Z axis physically move towards the home switch when you start homing?

Is the Z axis home switch detected?

 HOME_SEARCH_VEL = -10
 i.e. change the sign in the ini file to -ve or+ve

Yes ok, but theseŝ are direct interventions in the INI file.

As PCW mentioned and I agree, I would like to make as many settings as possible with PncConf.

I would first check that your X,Y,Z directions are correct
(by jogging and watching the movement and position display)

- yes, that makes sense

Then change the sign of the speed for homing if
is wrong


- yes, and this has to do with the settings on the PncConf windows of the X, Y and Z axes. Perhaps a screenshot, please?

Notice where the mouse pointer is, that should be as in picture if the home switch is at maximum Z travel.

Does the Z axis physically move towards the home switch when you start homing?

- since Z axis is referenced as the first axis, it references in the direction of Z- to the PNP contact (steel)
- if errors would not appear in the reference run itself, the Z axis would stop at the end contact Z-

Is the Z axis home switch recognised?
- Yes, I can confirm this, but I have to jog manually to Z-, then the Z axis also stops there at the end contact

- if no errors appear on the reference run, the Z axis stops at the contact (as a reminder it references in Z-)
- then it is the turn of the X axis
- if the X axis has also been referenced without errors, the Y axis would start referencing, but I interrupt this because servo 1 and 2 are not Cartesian tuned. I mean that the machine starts referencing without the display changing from 0, 1, 2 and 3 to Cartesian.
I assume that this must happen first, otherwise the two Y servos do not run in parallel or only one!?

Does Z home properly if you start homing when close to the home switch?

Have you verified that the Z scaling is correct?
 

Positive = 0
Negative = -200

the Z-axis still moves in the Z- direction for referencing, but only moves about 30 mm at snail's pace.
