Hello, in TNC 426/410, how can I view the absolute value after applying a tool offset? There are three or four position values available, such as actual, reference, distance to go, etc. Unlike Fanuc or other controllers, which display a Z value of zero on the top surface of the workpiece after taking the tool offset, the TNC does not show the absolute value after the tool offset is applied. need to advise. I am using a cam generation software to get G-codes in iso format. please look sample program which is run sucessfully.

Since you’re using cam generation software for G-codes, make sure your offsets are correctly set in the program. Sometimes, the software might handle offsets differently than the controller, so double-check that.

I don't know what you want to say..I am talking about tool display value on the machine screen when taking tool offset from work piece surface

Have you tried using Heidenhain coding instead of ISO

ie... "Toolcall" instead of "M6"

Our iTNC530 had issues with a Fanuc type of post processor, until a proper Heidenhain post was purchased.

no don't have Heidenhain coding post-processor can you show me the format of your post-processor output codes?

Probably better to show you from a dedicated site...
We started to make little scripts in MDI, using the control keyboard. Once starting the command, it would prompt you with correct options to complete the line of command.
Hopefully, the site gives you a concept to build further.
