Hi Patrick,


Sorry for delays,

1*For the structure of the cabinet, it is preferable in this case to use the double back to create a groove on one side of the upright only (left-hand area).

Even if the panel is set to nil, you use the upright to cut it, thus creating a groove on both sides of the upright.

2* Without having your Post Pro, I can already see that in your sub-methods you have an additional gap of 1mm in thickness.

which already makes a minimum groove in the output of 8.3 panel thickness + 1 mm in sub-method = 9.3mm

– In classic cabinet in laminate I recommend to use  0.5 in thickness and Inner positionion, here is see it is set to centered?
and unless there is a configuration error, an 8 mm cutter would have no problem making a larger groove.

Can you please check PP setup

Lastly, I see that you’ve set all the sloping edges to (Straight Edge +), you can save time by changing the PP chamfer option to Ignore, which will automatically output a chamfer in Straight Edge +.

Good Afternoon Gents

I have a cupboard which has a inset back in one side.  When I split the back in the centre of the panel and then make one side a nil panel, the output gives the 9mm groove cut all the way through.  The vertical divider is overpassing the back and the back is inset 20mm.  How do I stop it cutting all the way through in this scenario?


In addition when I do this the groove is supposed to be 8.8mm, but the output file gives the 12mm routing bit so luckily the CNC gets to that point and just stops as the geometry is incompatible with the bit.  Is there some way I can set this as all other grooves for back panels are fine and use the 8mm bit?
