Bug in Box Joint Double round

Post by lagore »

There appears to be a bug in the 'Box Joint Double Round' all "Y" values are offset by +1mm.
As an example the following bit of gcode using a 10mm thickness board with a 5mm router bit and no 'Face offset or Finger backset' and finger = tool dia
G0 X104.7500 Y-11.5000
G0 Z-3.4000
G1 X101.0000 Y-11.5000
G2 X96.0000 Y-6.5000 I0.0000 J5.0000
G1 X96.0000 Y-1.5000
G1 X96.0000 Y-6.5000
With no 'Face Offset' the router would cut right up to the outside face of Board 'A' so with a 5mm bit the maximum 'Y' value would by "Y-2.5000" but as can be seen in the 5th line we have a value of " Y-1.5000" which would over cut the face by 1mm. The same happens with 'Board B'. It requires me to offset my cnc 'Y axis datum by 1mm then everything is cut fine.

Yes, the Y values should be -2.5 and -7.5.

What version of JointCAM are you using? I'm not seeing those results here. If your not using the latest version, try that first.

If a new version doesn't work, can you Save the project, and send me the file?
Also, go to the Configuration Tab, click Settings Files, and send me your Settings.ini file from the Config folder.

My bad!
For some reason when I installed the program it had a 1mm offset in the x and y axis offset, I never realised those settings existed even though I had gone over the settings tab a few times to try and find the problem.
Thanks for getting back to me so quickly.

I'll double check the installation files and make sure the offsets are set to 0 on new installs.
