Bob, the VCarve estimated time feature may be your best bet at what you are wanting. It has a correction factor you can use to improve its prediction accuracy, but in all honesty, it may still not be close enough for your needs.

Bob, Carve time estimates are based upon the number of lines of gcode already carved, the time required to carve them, and the total gcode lines in a file.

To manually control your laser click on one of the laser options and set the S value to 5 then click the M03 button. ...

Good Morning Jan, Click on the $I button and let me know what is displayed in the message box. You should also see the grbl version when PicSender connects. PS grbl version.jpg You can also view the version with the "$I" button. PS grbl version2.jpg I will load the same grbl version you ha...

Jan,
What version of grbl are you using? Grbl 9 versions do not support Automatic setting changes and does not have a Laser mode.

Jan,
Here is a screen shot of the Auto Settings in v.2.9.0.2.

Jan,
Yes, PicLaser only imports image files. It will only convert image files, not vector files, to .bmp.
