DFX kenne ich auswenig, da der Inventor dies ausgeben kann.


OK, dann schaue ich mir die Programm mal bei gelegenhit an. oder kann ich mir der DFX schon was angfanegn? für LinuxCNC?

Example of HAL configuration for plasma torch height control with THCAD2 7i96s

Category: HAL Examples

3rd The big problem is that LinuxCNC does not understand that only a frequency signal from 100 to 1000Kz determines the feedback of the Z axis position.

I think this was already discussed  in another thread. I think the best way to do this is
step by step

The first step is to scale the encoder velocity into the desired units (mm?)
This can be done with the encoder scale parameter, but it's likely you will need
an offset, in which case you can feed the encoder velocity through the offset
component. When this is all done you should have a direct scaled position signal.

To calculate the scaling you will need to move the Z axis to 0 position, read the
encoder velocity, then move Z a known distance (preferably near full range of motion)
and then read the encoder velocity again,


The second step is to feed this signal into the feedback input of a PID component.
this PID component will force the Z axis to follow the Z axis position command from
LinuxCNC.

If you setup a normal analog + encoder feedback LinuxCNC configuration
with pncconf for 7I77 hardware, all of setup/connections/components will have been created
for you and the main change that needs to be done is substitution of the scaled/offset
encoder velocity for the encoder position that pncconf setup.

Here is the manual for the plasma source I am using. I have someone to help me with the wiring of the voltage divider to the plasma machine but nobody for the Mesa board pinout. Someone will help me with the Linuxcnc setup of the mesa board and QtplasmaC.

I just need the examples to move forward
A while ago I was having another difficulty, with the automatic tool change, the LinuxCNC help files are in English and very confusing, only with a video showing step by step I was able to get what I wanted, below is the example video:



Below is the result of this example applied to my machine

I'm not as lay as you think, but I need a little push from some example code in a video to show the control of the plasma torch?

you mix "Z" and"z" than "z      0.4" and "z0.2" ... try to adjust these spaces from z to number on ngc code .... after maybe you have not enought z spaces on negative limit (for some offset for example)  ..... you check these?

Category: EtherCAT

if you share some terminal output maybe all more clear .... any how if you have update maybe need update ethercat masteer or maybe you have changed pc so need to change mac adress ata least. Try to write on terminal: ethercat master or sudo ethercat master .... so you can see if it is problematic.

Good news. I screwed off the BOB and found axis labels on the underside of the board. through a YouTube video, I stumbled upon, I deduced that the drivers were wired wrong, so after switching wires on the Z axis I could jog it. Now to connect the limit switches. And get the DC spindle moving on command.
Thank you for your help

Add setting to toggle display of one or two file managers in Probe Basic

Category: QtPyVCP

Thanks for this tip.
My machine is 2.3m x 1.3m.
For example, last week I had a very complex session prototyping a panel with about 200 holes in different shapes and depths. 
After a while you can't see much unless you clear the screen.

So, thanks a lot for your tip.
I will try it, if I`m able to..

hi all ... Hi Grotius ...

project complete with modification

.... after these  ..... problem was solved in few step with new c++ code for char and so (from GCC7 to GCC13) ... all other depends because not insert hal_connection(); call on mainwindows ..... any how these help me to remember what learn in the past ... Too many things to do... this way, you forget what you've learned.

@Grotius .... Yesterday you send me in right directions .... but not see it

Example of HAL configuration for plasma torch height control with THCAD2 7i96s

Category: HAL Examples

Good afternoon

I will try to be as precise as possible about what I am looking for, although the language barrier does not help.

1st The 7i96s electronic board was designed with an encoder input ENCA+ ENCA-, ENCB+ and ENCB+. This would be the basics to connect an encoder with output A and B and for everything to work perfectly.

2nd I need to connect only and exclusively to ENCA+ and ENCA- a single frequency signal from the THCAD2 board that resets to 100kHz in the low position and resets to 1Mhz in the high position. This has already been done successfully.

3rd The big problem is that LinuxCNC does not understand that only a frequency signal from 100 to 1000Kz determines the feedback of the Z axis position.

I can't believe you don't understand this, given your extraordinary skill. Some people want to tell me that I ask questions that are too obvious to be answered by the masters. So I challenge the creators of this technology to prove that they can do this simple application by showing me examples.

Unfortunately, I really believed in the technology from the manufacturer MESA, and I received a lot of help from Mr. Peter and this forum. But it seems that now I have reached a limit where no one can help me with this. To make matters worse, I have not yet found anyone willing to provide the service, even if I pay. This is sad, because MESA has everything it needs to be widely used to replace major brands. All that is missing is more examples and support from professionals like me.

Since you asked what I want to achieve, it is simply to control a hydraulic cylinder that repeatedly hits a metal plate, but this hit has to be at the right height down to the millimeter. The actuation output is controlled by the 7i77 electronic board and it plays from 0 to 10 V positive to go up and from 0 to -10 V negative to go down. Next to this cylinder there is a linear inductive sensor that has a 0 to 10 V positive output that at 8 V is with the cylinder high and 0 the cylinder low, this height return with millimeter precision goes to the THCA2 board that sends this information to the 7i96s board, MY GOAL IS that in the G code I can control z000001.000 or z000001.50000 to drill deeper or less deeply. Did I understand the objective? Is there any better idea, or is it very easy and obvious?
