Add Heidenhain 145 post

[fonsecr]

Add post to support Heidenhain TNC 145.

@Anonymous please give feedback here on the IdeaStation.

Requires careful testing.

1. Check output for drilling cycles.

2. Check RL, RR, R0 output.

3. And everything else 🙂

You can also compare output for the 155 post available here:

Yesterday I was trying this post to realy late night... I found two problems so far.

1. sometimes missing coordinate (probably if it's value = 0).

Example:

----------------------------------------------------------------------------------------

1 TOOL DEF 1 L+0,000 R+5,000

2 L Z+0,000 R0 F9999 M

3 STOP M00

4 TOOL CALL 1 Z S1000

5 L X+8,481 Y+17,434 R0 F9999 M13

6 L Z+15,000 R0 F9999 M

7 L Z+5,000 R0 F9999 M

8 L Z+1,000 R0 F1000 M

9 L Z-5,000 R0 F1000 M

10 CC X+10,000 Y+0,000

11 C X+24,658 Y+9,560 DR- R0 F1000 M

12 CC X+10,000 Y+0,000

13 C X+27,500 Y+0,000 DR- R0 F1000 M

14 CC X+10,000 Y+0,000

15 C X+0,000 Y-14,361 DR- R0 F1000 M

16 CC X-10,000 Y+0,000

17 C Y+14,361 DR- R0 F1000 M Here, there should be X+0,00 before Y, otherwise TNC will not accept program.

18 CC X+10,000 Y+0,000

19 C X+8,481 Y+17,434 DR- R0 F1000 M

20 L Z+15,000 R0 F9999 M

21 L Z+0,000 R0 F9999 M

22 STOP M00

----------------------------------------------------------------------------------------

Without " X+0,000" TNC gives error. It needs 2 coordinates, even if X = 0.

Adding it manually - makes program works perfect.

2. milling full circle gives wrong command:

10 CC X+0,000 Y+0,000

11 CP PR+55,000 IPA-360 DR- F1000 M

According to the instruction from Heidenhain it schould look like this:

10 CC X+0,000 Y+0,000

11 C X+... Y+... DR+ RR F1000 M

Making for example 3/4 of the circle works fine. Maybe not how instruction says - but works:)

Thanks for your feedback.

We have updated the post regarding the arc issues, so please download and test it again.

Hi all this is great and mostly working so far but i have a problem with Linear interpolation... 

4 TOOL CALL 2 Z S2500
5 L X-58,349 Y+81,957 R0 F9999 M13 - This is fine 
6 L Z+15,000 R0 F9999 M
7 L Z+5,000 R0 F9999 M
8 L Z-4,920 R0 F800 M
9 L X-58,345 Y+81,950 Z-5,050 R0 F800 M - Its giving three coordinates (Controller only allows two)
10 L X-58,332 Y+81,930 Z-5,178 R0 F800 M
11 L X-58,312 Y+81,897 Z-5,303 R0 F800 M
12 L X-58,283 Y+81,852 Z-5,422 R0 F800 M
13 L X-58,247 Y+81,795 Z-5,534 R0 F800 M
14 L X-58,203 Y+81,727 Z-5,636 R0 F800 M
15 L X-58,154 Y+81,650 Z-5,728 R0 F800 M
16 L X-58,099 Y+81,563 Z-5,809 R0 F800 M
17 L X-58,039 Y+81,469 Z-5,876 R0 F800 M
18 L X-57,975 Y+81,369 Z-5,930 R0 F800 M
19 L X-57,908 Y+81,264 Z-5,969 R0 F800 M
20 L X-57,839 Y+81,155 Z-5,992 R0 F800 M
21 L X-57,769 Y+81,046 Z-6,000 R0 F800 M

Im no expert is there something i could be doing wrong?

The post could be modified to discard the Z coordinate. But this is really not what you want when the toolpath actually has 3D motion like in your case.

So first thing to check is that you actually generate toolpath that only moves in XY and not XYZ at the same time. You should be able to adjust the linking and ramping settings normally. I assume you use 2D Contour and 2D Pocket. E.g. if your CNC cannot do helical ramps then you need to use a different approach.

Hi i've been using the TNC145 post processor , i have an issue with 2D pockets ....

So i'm not using Helix i'm Plunging and command lines don't seem right.

For example i plunged down as i would expect to but i still get this in the command lines with 3 coordinates.

The TNC145 controller only accepts 2 coordinates (L) see red below

let me know what you think ? 

[zebb.guy]

Hi fonsecr, thanks for the reply

I would like to modify the post as i don't see the 3D motion in those command lines. 

Z is already in this position so even with the lines left in we would still only have movement on  X/Y axis.
