All set up and printing! Quick Question on XYZ Drive maximums



  • Rostock Max V2 with DuetWifi 1.21RC4. Loving Duet3d over the Rambo board so far. Way easier to setup than I thought. Printing just fine even with manual bed calibration till I get my FSR's (manual calibration was also excellent vs Repetier's), but just wondering what these drive maximums refer to exactly and where are these limits set?

    I have a 365mm build Z height and am wondering if 200mm~ limits like these will stop each tower at 200mm instead??

    I'm glad you like the Duet. The axis limits and endstop positions for most printer types are set by the M208 commands in config.g. For deltas it's a little different. The minimum Z is still set by M208, but the printable radius is set by the B parameter in M665.



  • Ah right, so thats printable radius.. makes more sense (I was thinking z height). Any reason they would be those figure though? I dont see them referenced by my M665 in config.g:

    M665 R144.839 L291.6 B140 H365.699
    M666 X-0.71 Y0.07 Z0.64 A0.24 B0.54

    I'm guessing that those figures reported by DWC are the M208 defaults, in which case they are not relevant to delta printers except for Z min. I've made a note to look into this.
