Raise torch at end of cut program?

General
1

I am trying to learn CNC plasma. We have a Shop Sabre machine at work. When using Enroute to make the .tap file the torch raises at the end of the program. I would like to use sheet cam instead of Enroute. Where to I change the settings to lift the torch to home position when finished cutting in sheet cam?

Check the settings menus. Can’t remember which one. There is a parking position option. I think there might have to be a section in your post processor for it to work, but I’m not positive since I don’t use it.

@Deucer , timely question and you have a few options-

  1. Not knowing what version of sheetcam you are using, I’m attaching the v7.1.40 ‘ShopSabre plasma’ pp, it has a fix unrelated to your request in the installed form, but I also added your request of lifting Z to safeZ at end of job, in OnFinish(). If you are using the same named pp, just import (menu Options-Machine-‘Post Processor’, Import button) the attached copy and you should be good to go.
    safeZ is a pp variable set by menu Options-‘Job options’-Material, field ‘Rapid clearance’.

  2. Regardless of use of this attached pp, you can lift Z at end of job via menu Options-‘Job options’-Parking and setting the Z field. See Help from this window for more info.

  3. Lastly, we are in the process of revising significantly the ShopSabre plasma pp. In collaboration with ShopSabre and their choice controller mfg WinCNC, a new Sheetcam / ShopSabre / WinCNC programming interface is in test mode now. The significant difference to prior versions of the Sheetcam pp is that the WinCNC material list can be disabled in lieu of using all sheetcam tool, operation, and Path Rule definitions. This differs from prior versions of these products in that the WinCNC material selection list controls ALL cut parameters except kerf offset and sometimes feedrate, and as you noticed, there is no Z motion in the current gcode. All of these params and Z motion is handled by WinCNC macros. Going forward with the new pp and interface, you will have a choice to use sheetcam as is conventional with most other controllers, utilizing full sheetcam cut parameters, including new custom parameters for ShopSabre. The main user interface improvement is that duplicate sets of cut parameters will no longer be necessary, that is having a copy in WinCNC and another identical copy (in part or in whole) in sheetcam.

Thank you for the great response. I will try option 2 when I get to work. Option three sounds interesting. Shop Sabre uses Win CNC. The PP WinCNC THC works fine with the machine. Shop Sabre Plasma does not. Our machine has a laser for locating the torch. With the Z axis not lifting the air blowing into the water table blasts up and covers the laser with crud. Lifting at the end will help a lot.

Thank you, I found the park setting after reading the posts. I will try it when I get to work.
