Hi all,

Was just hoping someone had a post for tnc 145, im using inventor hsm 2.5D. Downloaded a few tnc 151 & 155 posts but they all seem to be a mile off and i haven't done any editing before:culpability:.

Thanks in advance!

Jack

I moved from Fusion 360 as sorting post processors for my TNC355 was a BIG headache. I wanted to do 4th axis work but the way the CAM side was written was a nightmare

I bought CAMBAM - a far simpler product with nothing like the Fusion sophistication, but it worked and altering Post P's was much easier !!!

Don't forget that post processors are specific to the CAM package you are using

I've looked into cambam before, but as far as im aware it only converts to G-code? The TNC 145 can only read "heidenhain language".

Cheers,

Ade Vickers modified a post for his TNC151 using conversational code - it's on the CamBam forum - just search for Heidenhain

Finally got it working! used Ade's 151 post processor took quite a lot of modifying to work for the 145 hey ho i now have a cam bam'd name-plate!

Chuffed to bits.

The circle was a mistake but it still looks neat. :)

Thanks for all the help.

Cheers,

Jack

Thanks! I can post it on the cambam forum. :)

You find the file i in the "Tools" meny, and then "view program directory" or something like that. I'm at work now, got no access to cambam. It is on the right of the top menu bar anyway, you'll find it! Then it's located in the "post" directory. Had a hard time to get the TNC 151 post running before i found that directory. :)

Maybe you can change it to ".txt" ? :)

Did you use the .vbs file that was supplied with the 151 conventional post? Upload that too. It`s located directly at c:\

Sorted. This PP is not 100% by any means, but its a good start.

Couple of issues -

After a CC line the Post outputs I value for an incremental move in X and J value for Inc move in Y... i didnt know how to change this so i just open programme in notepad and use "replace all" to change all I's to "IX" and all J's to "IY".

Also anywhere that the programme has a "stop" or "begin programme" or "end programme" the TNC will not read, i simple replaced all of these with a tool call or tool definition (also did this in notepad).

Then your ready to go! i didnt bother much trying to fix the post processor because it didnt take that long to fix in notepad. If anyone can improve the post i'd appreciate it if you put it on here!
