SheetCAM Path Rules

SheetCAM path rules can be setup for things like turning off THC control on small parts and slowing down on corners.

 

Rules to prevent diving (Turn THC Off):

Under the options menu is job options. In there select the path rules tab and you can edit those rules parameters for your liking.  The idea is they turn the torch height control off at certain points to prevent it from diving.

If no rules in place, see if the THC Enable/On and THC Disable/Off Start Codes exist when trying to add a new rule set. If not you will need to create the code first so close out of this window and follow directions for creating code snippets. If they do exist you can adjust the settings as needed, but a starting point is shown below.

NOTE: the start and end code name is whatever name the code snippet was give and may be different than indicated below.
