Help on updating Gmoccapy 1.5.8 to current release?

I have working versions of Axis 2,7,11 and Gmoccapy 1.5.8 that took me forever to get customized/debugged since I am a Linux newbie . So I want to get current on my Gmoccapy but I am nervous about losing my current functionality and not clear how to even update my existing Gmoccapy. Questions:

1) The automatic updates on my Linux PC seems to keep me current on Axis versions. I assume Gmoccapy isn't automatically updated, correct?
2) Can I install or update the latest Gmoccappy and still have the 1.5.8 version on my machine? I would like to have the option of having my working version of 1.5.8 while trying to debug the latest Gmoccapy.
3) In simplistic layman's terms, how do I update to the current Gmoccapy? I've searched and read the Gmoccapy doc but have not found walk through steps.

I'm running Wheezy. Any help appreciated. Thanks!

Updating / Upgrading LinuxCNC versions should not normally touch anything in your home LinuxCNC directory, which is where all your customisations probably are.

The exception to this is 2.8 / current master which needs to update the HAL and INI files to suit the new system, where joints and axes are not the same thing.

This script _shouldn't_ lose any custom changes, and it makes a complete backup of the original config too.

Good to know but how do I get the current release of Gmoccapy? Or is the 1.5.8 Gmoccapy the current release for the current release of 2.7.11 Linuxcnc?

@Nigel,

You can update with the synaptic package manager. This is in your system menu if you are using linuxcnc from installed from cd.
But be carefull. First copy all your current project file's to be save. Then it's save to update.

If you do step config wizard with the latest linuxcnc version, the system can import your old files (select this option) and will update them with joint value's etc.

Also with step config wizard you can choose for a Gmocapy layout, this is perfect for you.

It works, i did it before.

2) Can I install or update the latest Gmoccappy and still have the 1.5.8 version on my machine?

Yes this is possible to do add a linuxcnc run in place version. This works good.
But takes time to understand how to install.

You can do this with " git clone ...." the proces can take several hours to understand, because you need also several
building dependecies that must be downloaded. After that you can compile Linuxcnc and run it in the script directory.

If you are using LinuxCNC 2.7 the latest gmoccapy release is 1.5.8
if you are on master the latest release is : 2.3.3.2

That is related to the difference in handling Joints and Axis in the new master branch. As that one will be the future "stable" I decided to not update any more the release 1.5.8, only bugfixes are pushed to 2.7 from my part.

If you want to update to gmoccapy 2.3.3.2, the easiest way is to include the buildbot repositories in your sources.list.

Be aware, that some important changes has been done from 2.7 to master branch, so editing hal files might be needed. Normaly everything works out of the box, because there is included a script, what will run on your 2.7 config automatically if you first tsart your config with master.

@Norbert,

The update in the code is working good. But i have my quistion's about several changes in a later stadium.

But if you do the JT tutorials at this moment, you will find out you do this tutorials with old configuration files while
you don't know you do old programming style. How to solve this issue? Contact JT?
