Practical Tip: How to organise Postprocessors – In Video format
SYMplus™ provides a list of around 50 Postprocessors. In reality, you will hardly ever need all of them. Mostly you work with one or a few. So selecting the right postprocessor can prove to be a nuisance with such a large list. Here is a tip that can help you organise those Postprocessors efficiently: Create a second folder for postprocessor parameter sets, and copy the postprocessors you currently need into this folder. That’s it.
In this practical tip, you will see how this works:

6 steps to an organised Postprocessor list.
SYMplus™ provides a list of around 50 Postprocessors. In reality, you will hardly ever need all of them. Mostly you work with one or a few. So selecting the right postprocessor can prove to be a nuisance with such a large list. Here is a tip that can help you organise those Postprocessors efficiently: Create a second folder for postprocessor parameter sets, and copy the postprocessors you currently need into this folder. That’s it.
Here it goes:
Step 1: Open the “Work plan” operating mode (alternatively also “PAL simulator” or “Simulator”).
Step 2: Select “F1 File” > “F5 Management” > “F4 Postprocessor Parameter”.
Step 3: Mark the file(s) relevant to you and …

SYMplus™ Update 63 is now available to all customers with plusCARE™ and includes new features as well as great improvements.
Scale the font size in the editor of the simulators to 200% by default (e.g. for the beamer image of the teacher’s computer)
When creating PAL gap-filling tasks, store individual instructions for each gap in the text
Receive the new simulators for the SINUMERIK 808D control system
The exchange of revolver stations and individual allowance presettings for roughing, facing and grooving in turning operation was never so easy
In addition, many detailed improvements in the simulators for PAL2020, SIEMENS 810D/840D and HEIDENHAIN allow for more effective work. The use of mobile licenses and the sources for the creation of individual macro work steps (by customer order) have also been improved. Other sample programs have been revised according to PAL2020 (for new installation as part of the user data).
More information about Update >
Lastly, we want to pause and look back at the past year.
It was great to see that many events and meetings took place this year. It started with the BETT UK education fair in London in March and ended with the BZI Remscheid open day last month.
The fact that face-to-face meetings were more feasible again than in the past two years was also evident at the KELLER.Academy: close to 40 guests came to the Academy courses this year (in comparison: there were less than twenty in 2021). In addition, the KELLER.Academy celebrated its fifth anniversary and held (virtual) training courses in Pakistan and Mexico, both of which are far away. In September, we published the new “SYMplus™ license via the Internet”, with which you now only need one KELLER ID to let several users work with SYMplus™. And in October, a new edition of the workbooks was also published.
Look out for more new improvements next year!

PRACTICAL TIP – How to organise Postprocessors
December 2022
SYMplus™ provides a list of around 50 Postprocessors. In reality, you will hardly ever need all of them. Mostly you work with one or a few. So selecting the right postprocessor can prove to be a nuisance with such a large list. Here is a tip that can help you organise those Postprocessors efficiently: Create a second folder for postprocessor parameter sets, and copy the postprocessors you currently need into this folder. That’s it.
Here it goes:
Step 1:
Open the “Work plan” operating mode (alternatively also “PAL simulator” or “Simulator”).
Step 2:
Select “F1 File” > “F5 Management” > “F4 Postprocessor Parameter”.
Step 3:
Mark the file(s) relevant to you and add them to your personal selection list with “F5 Add”. The selected files are then each marked with a black triangle/arrow.
Step 4:
Then select “F2 Copy” and choose the destination folder from the list. Confirm your selection with “F10”. If you don’t have a folder yet, create one by clicking “F2 Add …” or ‘link’ to an already existing one. In our example, the new folder is called “MY_PPs” and is a subfolder of the default folder “PARAM-SA”.
Step 5:
Finally, enter the name under which the folder should appear in the “SYMplus™ File Management” in the future (for example: “My Post Processors”) and confirm with 2x “F10”.
Now you can select your newly created folder from the folder list. Click on “F10” to open the folder. Subsequently, you can exit the parameter set management with “Esc” or “F10”.

Practical Tip: Rewrite old PAL programs for the PAL2020 – In Video format
With the PAL2020 reform, some of the commands in the PAL coding were changed. The commands were changed so that programs written after PAL2008 or PAL 2012 will no longer run and lead to any error messages in the newer PAL2020 simulators (or PAL2020 C/Y or PAL2020 3+2). This means that you have to rewrite the program blocks almost completely – and that takes time.
A faster way to do this is to use the “Find/Replace” trick:

PRACTICAL TIP – Rewrite old PAL programs for the PAL2020
September 2022
With the PAL2020 reform, some of the commands in the PAL coding were changed. The commands were changed so that programs written after PAL2008 or PAL2012 will no longer run and lead to any error messages in the newer PAL2020 simulators (or PAL2020 C/Y or PAL2020 3+2). This means that you have to rewrite the program blocks almost completely – and that takes time.
A faster way to do this is to use the “Find/Replace” trick:
This trick works when “translating” PAL2008 or PAL2012 commands to PAL2020, because there is a simple mapping between old and new here. Below, we will briefly touch on how you can rewrite the cycles more easily. You need this, for example, for the piercing cycles in turning, which are still called G86 or G88, but have many new or changed cycles.
Step 1
Open the program, which you have already programmed in an older PAL coding, in the “PAL2020” mode. You will then get the following message: “The NC program is faulty!” Delete this message by pressing “F10”. The last block that does not correspond to the PAL2020 coding is now marked in the editor. In the example (exercise program “LAGER3” from the workbook “Plane Swivel”): “N65 G17 CR180 AR90”. Here (and in many other places in the program) G17 must be replaced by G15.
Step 2
Now select the “Search/Replace” function using “F1” and enter “G17” in the “Search for” field and “G15” in the “Replace with” field:
Click on “Replace All” to replace “G17” with “G15” in the entire document. Finally, accept this edit with “F10”.
Step 3
Subsequently, in our example, the line “N45 G48 G40 R10 Z0” is marked as incorrect, because after PAL2020 the commands for tangential approach and departure have also changed. Replace them according to the same principle: “G48 G40 R” becomes “G40 G46 RR”. And then “G41 G45 D” = “G41 G45 DL”.
Step 4
For the training program “LAGER3” all necessary replacements are done with it, and you can use “F7 Editor” to switch back to the “guided mode”. There you can simulate the program using “F9” and finally save the changed program with for example the name extension “2020”.
A complete table with a comparison between “PAL2008/PAL2012” and “PAL2020” (as of summer 2022) can be found at the very bottom of this post.
Rewrite Cycles:
This is not quite as simple as the PAL commands. But with this little trick, you will surely save some effort:
Step 1
Start by commenting out the “old” cycle blocks in the editor. Then program the cycle blocks again in the guided mode (“F7 Editor”). Note that commenting out changes the line numbering (which affects jumps with G23), since pure comment lines have no line numbers. To avoid this, write the previous cycle as a comment after a regular (innocuous) NC block. This will then look for example like this:
N28 M1 ; G86 X60 Z-55 ET54 EB6 RO-0.5
Step 2
After you have changed the cycle set, just delete this comment again.

Practical Tip: Clever Cutting and Reclamping – In Video format
By loading the video you accept YouTube's privacy policy.
Learn more
Cut a turned part to be machined on both sides from the bar and at the same time programme the second machining side. If the length of the blank is defined to such an extent that at the end, there is enough material to “cut” out of the protective zone for the chuck or the clamping jaws. However, if you proceed as described, after the “cutting off” step it would result in the half-finished workpiece falling in the simulation as in reality in the chip tray or a part catcher. Afterwards, the geometry is no longer available in the working plan for further machining.
But what is the solution then? The practical tip gives you the answer to this question.
