Just looking to turn off Z-Grid, but before I do, What are the benefits of having z-grid over a the regular calibration. Using a delta bot.
You want calibration if your arm length and tower radius is not 100% the exact value, Smoothie uses it to find the right value.
You want delta-grid if your bed is not 100% flat, Smoothie will probe and compensate for that.
Does the delta - grid compensation remain active for all layers of the print?
If you had a bed that isn't perfectly flat.. Say it had a high spot somewhere.. The grid compensation would be great for getting the first few layers to stick. But would the printer then be adding that high spot to the print at the top of your part?
Yes it's active for all layers. Progressive fading of the levelling is a planned feature, it's just not been implemented yet, I don't believe it's too hard to do.
Regarding using delta grid compensation on a Cartesian printer -
I have a rectangular bed and I am unable to get the probing points in anything other than a square.
If I reduce the absolute maximum travel option for one axis it ignores this value and only goes off of the levelling strategy delta grid radius.
I have tried disabling the grid radius value and then the printer only probes around a 50 mm window
I have tried with the delta grid is square both true and false
Any help would be great
