Position PCB in preview and cutouts (BUG?)

[mrWheel]

@rosenhauer,

YAPPgenerator_v3.scad [v3.3.7 (2025-04-17)]
OpenSCAD v2025.08.19 [git 6afea6fca]

I have these values:

//-- Defined here so you can define the "Main" PCB using these if wanted
pcbLength           = 100; // front to back (X axis)
pcbWidth            =  98; // side to side (Y axis)
pcbThickness        = 1.6; 
standoffHeight      = 3.0; //<<<<<-- How much the PCB needs to be raised from the base to leave room for solderings and whatnot
standoffDiameter    = 7;
standoffPinDiameter = 2.4;
standoffHoleSlack   = 0.4;

Mark the standoffHeight!

I don't have standoffs defined.

I have this connectors array:

//===================================================================
//  *** Connectors ***
//  Standoffs with hole through base and socket in lid for screw type connections.
//-------------------------------------------------------------------
//  Default origin = yappCoordPCB : pcb[0,0,0]
//  
//  Parameters:
//   Required:
//    p(0) = posx
//    p(1) = posy
//    p(2) = StandHeight : From specified origin 
//    p(3) = screwDiameter
//    p(4) = screwHeadDiameter (don't forget to add extra for the fillet or specify yappNoInternalFillet)
//    p(5) = insertDiameter
//    p(6) = outsideDiameter
//   Optional:
//    p(7) = insert Depth : default to entire connector
//    p(8) = PCB Gap : Default if yappCoordPCB then pcbThickness else 0
//    p(9) = filletRadius : Default = 0/Auto(0 = auto size)
//    n(a) = { yappAllCorners, yappFrontLeft | <yappBackLeft> | yappFrontRight | yappBackRight }
//    n(b) = { <yappCoordPCB> | yappCoordBox | yappCoordBoxInside }
//    n(c) = { yappNoFillet } : Don't add fillets
//    n(d) = { yappCountersink }
//    n(e) = [yappPCBName, "XXX"] : Specify a PCB. Defaults to [yappPCBName, "Main"]
//    n(f) = { yappThroughLid = changes the screwhole to the lid and the socket to the base}
//    n(g) = {yappSelfThreading} : Make the insert self threading specify the Screw Diameter in the insertDiameter
//    n(h) = { yappNoInternalFillet } : Don't add internal fillets (external fillets can still be added)
//-------------------------------------------------------------------
connectors   =
[
// 0, 1, 2, 3,   4,   5,   6,    7, 8, 9, ...
  [5, 5, 3, 3.2, 7.0, 4.3, 8.0,  default, default, yappAllCorners, yappCoordPCB ]
];

This is the result:

If I change standoffHeight = 8.0;

This is the result:

Obviously the PCB is not shown at the right height. And also in preview the connectors on the lid disappear (same goes for button cutout and other cutouts).

Back to standoffHeight = 8.0;

[rosenhauer]

I believe the PCB position is correct. How the connector is defined is the issue.

connectors =
[
// 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, ...
[5, 5, 3, 3.2, 7.0, 4.3, 8.0, default, default, yappAllCorners, yappCoordPCB ]
];

The third parameter is the height of the connector from the specified coordinate system. Since it is 3 and the yappCoordPCB is specified the connector top is 3mm above the PCB.

if you want it to be to the bottom of the PCB then you can specify

[ 5, 5, -pcbThickness, 3.2, 7.0, 4.3, 8.0, default, default, yappAllCorners ] // the , yappCoordPCB is the default so not needed

with and without the PCB shown.

There was a issue if you specify a different pcbGap (I had changed it to force the gap to 0 - don't remember why or what I was testing but I've put that back - and pushed the update out)
