How much probe points is too much?



  • My current HEVO has a 500 x 500 mm bed. Right now I'm using a 6 x 6 grid for 36 points, but due to using smooth rods (12mm for all axis) it still has a slight shift. 6 x 6 works but there are small areas where it gets a little too close to the bed that it curls a little, still sticks but doesn't make a pretty first layer. I'm thinking of 7 x 7 but would that be overkill? Using precision piezo Orion so would that much probing shorten the lifespan of the nozzle (I do plan on buying e3d's new nozzle X or tungsten carbie nozzles which are much harder and tougher)? Thanks.

    Hi,

    I used the max possible. It was slow but produced very good results. My probe uses a micro-switch so no issue with problems with the nozzle.

    Try it yourself and compare the results against what you do now - nothing to lose but time.

  • measure the repeatability of your probe and increase the speed of probing to see when it becomes inaccurate
    see https://forum.duet3d.com/topic/6962/m48-measure-z-probe-repeatability-and-print-to-serial-output/4

    currently the max probe points are 441

    also you can save the probed map and load it instead of probing each time.



  • I use the max probe points as well since the bed is quite stable I only have to do it very rarely, which is good because it takes about 45 minutes to probe the 300x300 bed.
