(not really) New machine geometry for plasma

Category: Plasmac

If you have no space you can mount a Kuka robot on the seiling. :-)


But I think plasma makes some mess, so a big feature is the water tray.
I skipped any ideas of laser or plasma. Laser I find too expensive for my hobby. $$$ and a plasma has to compete with the local laser company that cuts things for a small fee.

question of Homing was created by Masa

question of Homing

Category: EtherCAT

I am using LinuxCNC+EtherCAT to retrofit an old NC controller in Japan. I am not good at English, so I am posting on the forum using Google Translate.

I apologize if it is difficult to read.

I am currently using an old torque-controlled servo amplifier controlled by Beckhoff's EL5101+EL4132.

The problem is that in Homing, Index-enable is connected to jioint, PID, and Encoder, but when it is moving at the HOME_LATCH_VEL speed, when it seems to detect the C phase of the Encoder, it goes into a runaway state for a moment and immediately goes to the HOME_FINAL_VEL speed.

After Homing ends, the same phenomenon does not occur when Homing is performed again. It only occurs during Homing immediately after powering on.

When I made it with EM7004 before, I was told that I did not connect Index-enable to PID, but this time I am having trouble resolving the problem.

I cannot increase the PID gain because it goes out of control.

I am attaching the INI and HAL. Please let me know if there are any mistakes.

I am using LinuxCNC 2.9.4. The EM7004 system was created with 2.3.2 and has not been upgraded.

I have asked a question on "General LinuxCNC Questions" about whether there is a problem with the PID, but I was unable to find a solution.

Thank you in advance.

I really like the look of QTDragon_HD too. I am using it with a ASUS VT229 21.5" touch screen monitor. It works really well.

I think you would need to build from source so you can select the code branch via git checkout

How to Install an Older or Different Version of EtherCAT?

Category: EtherCAT

Dear forum members,
Hello!

I followed the stickied post to install Linuxcnc and EtherCAT, titled "EtherCAT installation from repositories - how to step by step". I simply want to switch to a different version of EtherCAT for some experiments, without altering any other software or configurations. How should I proceed?
 Thank you very much for your valuable time and assistance! I look forward to your replies.
Best regards

(Repeated warnings about unmatched datagrams...)
Based on a cursory review, I speculate that the first system might be using a compatible version of the EtherCAT protocol with the slave devices (drivers), whereas the second system might be utilizing a newer version of the protocol that is not fully compatible with the older version supported by the slave devices.

Additionally, the "UNMATCHED" warnings seem to persist throughout the operation in the second system, indicating potential issues with data packet matching or communication synchronization. Note that I haven't included all the printouts, but the frequent occurrence of these warnings suggests ongoing communication issues.
