configure the "Axis Transforms"

[Saito Ryosuke]

Hello everyone.

I'm working on a machine with a configuration called "Peter's Head".

https://github.com/openpnp/openpnp/wiki/GcodeDriver:-Axis-Mapping#mapping-axes-to-headmountables

I'm trying to configure the "Axis Transforms" in this URL, but the current format of machine.xml 

seems to be very different from the one in the documentation, and when I add the configuration, 

I get an error when starting openpnp (there is a problem in line xx of machine.xml). 

There is a problem in line xx of machine.xml) when starting openpnp.

Has anyone had any success with "Negating Transform" since this format was introduced?

Hi Saito

you have the new OpenPnP 2.0 version. You need the new, much simpler approach. No more machine.xml hacking needed:

https://github.com/openpnp/openpnp/wiki/Mapping-Axes

You can read about the whole Upgrade here:

https://github.com/openpnp/openpnp/wiki/Advanced-Motion-Control

There is a table of contents at the bottom of each of these new pages.

These newer pages will be integrated into the overall Setup Wiki in the next weeks/months...

Hello, mark.

Thanks to your advice I was able to correct the Z2 axis to the desired motion.

Specifically, this is all I had to do and it was very simple. Excellent!

1. Create a "Zneg" using ReferenceMappedAxis

1.1. Change the Map Point B Output of Zneg to -1.

2. Change the "Coordinate System Z-Axis" of Nozzle 2 (Z was moving in the opposite direction) to the newly defined "Zneg".

Thank you!

Saito
