How to order the lines to cut in T2?
« on: March 02, 2017, 07:35:34 PM »
How can I order the lines to be cut first in T2?
I would like the contour rectangle to be the last to be cut, to give stability to the inside pieces until finished.
The wood blade has 1mm and a slight change in the angle of cut and focus.

I've been robbed.

There are a few ways to affect the order.

DXF Optimizer will rearrange the sequence to improve speed, but if you select center start it will begin with the shapes closest to the center and work it's way out. It won't always do the perimeter last though as it is just trying to minimize movement.

Another way, and perhaps the easiest in this situation is to use Inkscape and draw the border last. I took your image and converted it to vector in Inkscape, copied the border, deleted it and then pasted it back. So it was the last object. It will now cut it last.

I'm not sure if an FLV or animated GIF will work to show you the result but I will attach the DXF that you can run in the simulation to see the result for yourself. Do not use DXF Optimizer or it will change the sequence and break the "solution".

I'll try it here ...
I forgot to say that I have used Corel X7 and exported my files as .plt, it is the only one that opens in T2 with the exact measure.
How do I run the simulation?

Copied from the manual:

View
  Display a simulation of the G-Code
  Laser power is shown from yellow to blue (max power)
  Press o to show laser off as yellow
  Press b to show laser min as red and laser off as black
  Press r to show laser power using DXF colors (see below)
  Press s to run the g-code
       q changes speed (4 levels)
       Press s again to stop the simulation
  Use the 0, 1 and 2 keys to change the laser width (default is 0)
  Press 'g' to show/hide the origin (start) point
  Press 'f' to show/hide the frame
  Press 'd' to show/hide the dimensions (lower left and upper right positions)

I'm not sure if Corel sequences the PLT output based on creation or something else, perhaps making the border a different layer would solve it.

It does give me some ideas for a future improvement though.
