configurator and escher3d generate different bed.g files



  • Something I noticed last night whilst setting up my delta:

    Escher3d and the reprapconfigurator generate different bed.g files when the same parameters are being used. For example: 150mm probing radius, 10 peripheral points, 6 halfway points, 6 factor calibration give these results:

    ; bed.g
    ; called to perform automatic delta calibration via G32

    M561 ; clear any bed transform
    G28  ; home all towers
    ; Probe the bed at 10 peripheral and 6 halfway points, and perform 6-factor auto compensation
    ; Before running this, you should have set up your Z-probe trigger height to suit your build, in the G31 command in config.g.

    ; Use S-1 for measurements only, without calculations. Use S4 for endstop heights and Z-height only. Use S6 for full 6 factors
    ; If your Z probe has significantly different trigger heights depending on XY position, adjust the H parameters in the G30 commands accordingly. The value of each H parameter should be (trigger height at that XY position) - (trigger height at centre of bed)

    Most obvious difference is the extra probe point from the configurator. Probably doesn't really matter much, but I thought I'd share.
