Error: Hit a floor during 13 point calibration

[m4ttsmith]

Hi There,

When I am doing a software calibration through matter control, on the second calibration point the nozzle wont move move downward toward the bed. Z height is registered as 4mm on the control page of matter control (I think it was 5 but I tried to move down 1 after the original movement).

When I open up the terminal to see what is happening the printer has run into some errors. I'll type from the movement command.

Error: A hit floor
Warning: Invalid delta coordinate - move ignored x:9728 y:5500 z:400
Warning: in queueDeltaMove to calculateDeltaSubSegments returns error.
Warning: executreGCode / queueDeltaMove returns error
G91

Error:A hit floor
etc...

I think I've run into a software limit but am not sure which one. Any tips for things I should look out for in the eePROM?

I looked at the firmware and the warning is it thinks tower A has been told to go below the bed. I would look at the x, y, and Z tower offsets. One of them may be a very large number. I think the should be set to zero when you start the calibration.

Hi Dale,

I have had a look at the EEPROM is it the Tower X endstop offset you mean? for Y and Z as well? These are all set to 0 in my settings.

All of them being zero is good. So my guess that maybe one of them was a large number and thus canting the bed falsely was wrong. Now I'm out of ideas. Sorry.
