RequestPause:Homing failed! message and weird coordinator during Bed Height map

danikurnianto

Somehow I got RequestPause:Homing failed! (and then stop any motion) message when I home from the position g1 x55.05 y54.91 z2

which is also from the position g1 x-55.05 y54.91 z2. Which is top right and top left.

But I got not a problem when homing from position g1 x-55.05 y-54.91 z2 and g1 x55.05 y-54.91 z2. Which is 'same distance from the center' but to the bottom right and bottom left.

And I also this issue when homing from g1 x55 y55 z2. I feel like somehow the firmware give up for not seeing the last homing slider.

Any idea why this happen? could I mess up a configuration?

The other question is:

why I got the host (and the LCD) show X55.05 and Y54.91 coordinate while I am doing Bed Height Map for Xmin:-55, Ymin:-55, Xmax:55, Ymax:55. Kind of strange, right?

Homing - what happens during homing? Shoudl only happen if printer height (delta right?) is too low to reach the top in 1.5*zlength.

Height Map: These could be rounding issues (only step precision for calculations) or come from bed rotation and coordinate changes. Z probing always disbales rotation and enables it back afterwards so you get a coordinate transformation added when reporting.

yes this is delta printer.

is that 1.5*zlength could be adjust?

Repetier

In eeprom settings you can set zlength.

But I thought the z max length is automatically generated by the autolevel G32? meaning I should not change manually after the G32 is finish.

Repetier

Yes, that is what G32 does and once it did 1,5*zlength will be outside the printer so homing always works. But if you start with a much too small value homing will not succeed if you start too far away. So you should start with a value that is near the truth, then autolevel and you are done.
