Z-axis switch bounces. V0.60 #19
Comments
There was never a debounce code in the firmware. But the speed for the second try of the z-axis has changed. It is now configurable and set to 50% of the homing speed by default. With 0.50 it was the same speed. Check this in configuration.h // For higher precision you can reduce the speed for the second test on the endstop set value to 1 for the old speeding. I guess hitting the switch with a slower speed made the difference. |
At this setting is not the problem. I just tried it. |
I have now flashed the firmware v0.50 - no bounce. |
I think you had an other definition of bounce. You didn't mean the printer bounced at z=0 but at some higher position, right! If i'm right with the assumption, the problem should now be fixed (still version 0.60). I had the number of steps for the x axis used, but the z axis needed more steps for a full distance. Haven't tested such high moves, so it went unnoticed. |
Yes, that's it! |
I've been using version 0.50 with no problems.
In the new version 0.60 of the Z-axis switch bounces at homing.
Have I missed a setting, or is it a fault?
I use a mechanical endswitch and a Sanguinololu version 1.3a.
