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.

Solved: Help with Busellato JET 2 spindle retrofit – VFD overload

Category: Driver Boards

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.

orient spindle with ethercat EL5101

Category: EtherCAT

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

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.

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!

LinuxCnc and Industrial Robot?

Category: CNC Machines

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.

Building a 3-axis plasma table with mesa 7i96s, THCad-2 and nema23 steppers

Category: Show Your Stuff

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?

Hi again. I have sorted the power issue (manual was no help at all). Now, I have it set to Linuxcnc using ethercat. It is all communication etc. I want to run the servo as a spindle motor so just have the target-velocity (60FE). How do I create the 'pins' to tell the drive to turn at say 1000rpm with an M3 command is given. I have done the many times using a VFD (much easier but space and weight limits force me to use a servo).

I am soooo out of my depth here, any help is always hugely appreciated. (I have already looked through the various threads and found no help after hours of scrolling)
