Now you can just drag a container into any Flex GUI and name it and magically the 3 point center calculator shows up.

This is the Axis style Flex GUI

I had installed LinuxCNC a few months back, but I didn't use it. I tried two days back to install Arduino, and the date is showing wrong on the taskbar, and I am unable to connect to the internet for browsing.

Let me know what I can do best. I always check the CMOS battery on Windows to see if it is good or not, but this motherboard is under warranty.

hello ,
i live in french, i'm french. I used VS code or Thonny

Actually I'm going to add that to the Flex calculators so all you need to do is drag a container into the GUI and give it the proper name. You can't get much more flexible than that. I'll also add a go to center button.

Hi, I now have a type mismatch between :

net s-drv-target-velo <= cia-s.drv-target-velocity => lcec.0.A6.target-velocity

I am at my wits end now.

I would use Flex GUI because it's super simple to add a Python Module that is connected to the GUI.


Took me about 30 minutes to add the center calculator including debugging the formula from spreadsheet speak to Python speak.

If you're interested I can attach the code.

Right, I think the V/F profile is wrong. You were showing 32 Amps on the Omron display when it overloaded. it needs to have the V/Hz turned down quite a bit.
You need to check the spindle manual to find out the correct V / Hz rating and then program that into the VFD.

I'm trying a new approach by removing the PID for orientation and replacing it with a near component.But it's worse; even the speed control isn't working anymore, nothing's moving...Where are my mistakes?
I started from a version with only one pid speed that works.
With errors like ./EL7-schaublin-28.hal:326: Signal 'spindle-at-speed' of type 'float' cannot add pin 'spindle.0.at-speed' of type 'bit'

 

I tried to merge my speed pid with a spindle orientation example from talla83
talla83.homepage.t-online.de/linuxcnc/20181124_Spindel_5i25.zip

I am not sure. I am attaching my xml file which I created from a thread online. I also did am xml using ethercat, but they are different.

There is another Mesa shop in the US

You will likely need to  either merge some parts from a standard step/dir hal/ini file setup,
or use either pncconf's discovery option or MesaCT to create a working 7I77 + step/dir setup.

Hello again,

While checking availability, I noticed that in terms of cost and stock it might be more convenient to go with the 6i24, since it is currently available directly from Mesa USA. Otherwise, I would need to buy everything from Eurosurplus, which ends up being more expensive overall.

Could someone please confirm the main differences between the 6i25 and the 6i24? From what I see, the 6i24 has no limitations on its connectors, so in the future I could also leave an extra port available to add another servo control board if needed.

Thanks a lot for your help!

It is possible to use LinuxCNC to run cartesian (ie xyz) gcode on an industrial robot. However, since the planner has no information about the kinematics used and 'assumes' a cartesian joint/axes configuration you will not get uniform velocities over the robot's work space.
If accurate path velocities are important for your application then you are going to have a hard time using LinuxCNC with a manipulator.

Are the following components suitable for making a voltage divider? My plasma has a 1:1 arc output.
 

Yes.

I'm using a TH-CAD2 in combination with two resistors in series and a 0.1uF capacitor to absorb the voltage spikes. Am I doing this correctly?
 

Yes, but wire one resistor to each side of the arc voltage, not both on the same wire. That makes it much safer in case the cable is kicked somewhere on the way to electronics and lowers the interference caused by plasma source.
And you can skip the capacitor as it does work without it, but i like to have it as it smooths the voltage readout and subsequently the torch motion up/down while cutting, but it will limit a bit the reaction speed.

What happens if a voltage spike does occur? Will the capacitor fail?
 

Usually nothing, if the polarity is correct.

Can I connect the start arc and arc OK signals directly to the Mesa board, or is it better to use a relay to protect the mesa board?
 

Yes you can, 7i96S has two fully isolated outputs ( 4 and 5 i think, double check that), so no need for relay.

Can I route these signals to the plasma cutter through the same cable as the THC?
 

Yes, if the resistors are mounted inside or outside the plasma source, but close to the plasma source.

The new power supply worked. No more such errors. Thanks!

I would like to add a fuse to the incoming +5v to the 7i96s. What rated fuse should i use for this?
