Loading different configurations during startup. was created by User_paulvdh_42

Loading different configurations during startup.

Category: Basic Configuration

I'm planning on building a CNC machine (euhm, more then one actually), and one of my goals is to be able to load wildly different configurations for the same machine hardware. Both locations and directions of X, Y, Z and rotation axis may change. How easy is it to do this with LinuxCNC? For hardware, I'm probably going for an Ethernet based MESA card, maybe also into EtherCAT, but that is for later concern. Can a different configuration be loaded when LinuxCNC starts? Can this be done on the fly, or does it require a restart?

I guess it would work to make a custom startup command, that first copies one of the configurations to a default location before LinuxCNC is started, but I'm hoping for a more elegant solution.

This may sound weird. To give a better Idea of the direction I want to go into, I've added a picture of the Hommel UWG2. This is essentially a flat base plate, and depending on how bolt-on accessories  are configured, it can be used as either a horizontal or vertical milling machine, or even as a lathe. One of the accesssories is a rotary table, which can also be bolted on in various positions. Other examples of such universal machines are the Koelsch/Beichle Comined universal, Aldrin universal machine and Meyer & Burger UW1 (Both Hommel and Meyer & Burger were later sold as (bought by?) Astoba.

Rotation around which axis?
I think for a five axis machine you would need Rx Ry Rz.

There is not much difference between E6021 and 6001. I usually use these modules on the codesys platform. If I have more time later, I will try to test linuxcnc, but this means it will take a long time. I will test and release a demo as much as possible.

resolved-- Regarding the data reading offset issue of the ether cat IO module

Category: EtherCAT

Thank you for your kind help. I have already conducted a joint investigation with OFF in the group. At present, there is no good solution for the time being.

Category: EtherCAT

Sorry, due to my personal technical reasons, the detailed explanation of this issue will be very verbose.
In fact, I have made a detailed list of pins. Derived from idx00~31, the test results are the same. Additionally, I also tested other models of modules, and the xml used was almost exactly the same, but the test results were fine. Meanwhile, I received a message in other communities: Someone used the module of the same brand (with a different model), and the test results were fine.
I have recently conducted more module tests made in China and discovered some patterns. I will release the results later.
The current apparent result is that for the module I mentioned above, Linuxcnc can only read 16-bit data originated from ethercat PDO. Even for a data range of 32 bits.
Here are some examples: Please look at the picture
For this kind of problem, I plan to conduct network data packet analysis later. Later, I will provide detailed network data results. Thank you all.

While waiting, you can use 7i84 OR 7i73 with 7i97T for testing or anything, without the 7i74, meaning only one at a time.

I would like to play Doom Eternal, but since i messed up my right index finger, it will have to wait.
Already on the third play through, still sweat a lot while paying on "nightmare"... :)
