EasyProbe + PGFUN 3D probe

Category: General LinuxCNC Questions

As I said this is another story. I am familiar with this kind of stuff. No timing caps, no analogue circuits etc are involved. Just voltage stabilisation functions in this cases. And I just dont want to have tantals on the board as long as I dont have to.

Ah and of course. No charging cap and so on. So low esr isnt a problem here too.

But thank you nevertheless.

Beware of changing cap types!

Multilayer caramics can change capacitance with voltage and stuff.

And ceramic caps are microphonic.

Tantalum caps don't degrade with age, only due to electrical abuse (which they are very suceptible to). (overvoltage, reverse voltage, etc.).

Read this before changing cap types: www.ti.com/lit/an/slva214a/slva214a.pdf

Thank you for your input, but at this time nothing I seem to do works out right. I clearly am missing something but I do not know what that might be. It's wonderful that a new version has a button for using a manual tool gauge, however after trying to follow instructions from this post - www.forum.linuxcnc.org/38-general-linuxc...-do-i-update-to-2-10 - and having the first two things fail with - www.linuxcnc.org bookworm InRelease' doesn't have the component 'master-uspace - I do not dare go any further as I do not want to risk what is working now. It took weeks to get the machine running and I do not want to have to start from scratch again. For now, I can at least set my tool height each time I change a tool by use a shim on the work piece top. A bit of a PTA but better than nothing.

Updating pncconf for 7i95t

Category: Configuration Tools

Can't find anyone who can " translate" the procedure mentioned by the author into " human" language?
is this a script?:
sed -i 's/inm.00/inmux.00/g' ~/linuxcnc/configs/<config name>/<config name>.hal

Where should I put " pncconffor7i95T.txt" ?
what is meant <config name>/<config name>.hal
how do I run the script ?

Getting Started with GladeVCP

Category: AXIS

Because Glade has a gui editor, vs hand coding xml files like PYVCP, I think it is best to just start playing with it. Load some of the demo sim configurations, then open those glade gui files using the Glade Editor program to get a feel for how those files are built and then make modifications of them. Then try to build your own VCP window.

The GladeVCP documentation really gives the impression that you have to build and do a lot with a Python handler file but you can do quite a bit without really needing much if any of one. However there is a lot more that you can do with Glade and a Python handler, that you could never even think of doing with a simple PYVCP gui. To the extent of even building an entire stand alone gui for Linuxcnc.

ethercat-conf.xml pdoentry limits?

Category: EtherCAT

When i created this thread, i didn't know, where this 10 limit comes from.
Later i searched the servo drives docs and even found the limit mentioned there...
Will try to move some settings to SDO.
But its still annoying, because homing alone has more than 10 PDO parameters (eg speed, torque limit, time limits, etc). Many of them are somewhat just "nice to have".
But it seems, if i want to use them, i would need to switch ethercat-conf.xml (multiple times) during a linuxcnc program run. If that is even possible.
However in the near term i will go the simple route and stay within the 10 limit.

Ohmic sensing with IPTM-60

Category: Show Your Stuff

Not really interested to produce and sell.
Would take so much time, time I want to spend to make new things.
And it's not so unique, it's a remix of existing ideas.
Quite convenient though.
I don't mind at all if you sell units, will only help people.

Does axis jogging work?
If you issue an MDI command (eg 'G1 x10 f1000') do you get a ''Motor 0 Positionssfehler'? If so try to lower the feed rate (eg 'G1 x10 f10').

Impossible to troubleshoot further without knowing more about your configuration so post your hal and ini files.

Theese berger lahr drives are known for having faults because of the old caps. So I already have new ones at hand. Tantals for example will be changed to multilayer ceramics, but that is another story.

Yes, suprisingly theese machines were sold as engraving machines. Really beefy engraving lol.

But of cause I will install a spindle with more power. Nothing fancy for this project. Just a er25 4kW spindle and an old vacoon vfd laying around.

ethercat-conf.xml pdoentry limits?

Category: EtherCAT

The PDO entries of the EtherCAT master are 128 in number. Any error will occur if the number exceeds this limit. For the same type of enumerated points, you can use the abbreviated form for writing. For example:<pdoEntry idx="6000" subIdx="01" bitLen="32" halPin="bit-in" halType="bit"/> Here, an input point with a sub-index ranging from 1 to 32 is declared.

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

Category: EtherCAT

Dear friends, hello everyone. Regarding this issue, due to the busy work, it has been a week since then. Currently, we have basically understood the problem. I extracted two different Ethercat master station data from Wireshark and conducted a comparative analysis. From it, we can see that the entries of the PDO have a slight difference in the arrangement order. The main difference is reflected in the two special status words, namely " {0xf200, 0x01, 16}," and  {0xf100, 0x01, 16}. We are currently in contact with the manufacturer to confirm these two PDO entries. These two entries are used for a special design. Additionally, there is a problem with the parsing data of the data sent from IGH to PDO by the IO module!

Servo Oscillation Issue at ±6.6V 5i25 + 7i77, Analog Control

Category: Basic Configuration

After a long break I'm back to the topic. I did some research, tried to swap the wires between the mesa and the servopack, but no changes. It's not a problem with the analog voltage as in the topic because if I set P=0 I can normally drive at high speed without a closed loop.
What should the encoder accuracy be set to?
Maybe I have set the scale too large or too small?
But I tried changing it to less and it didn't have any effect.
I'm still wondering if the analog wire can go parallel to the encoder wire, maybe it creates some interference.

I use analog jog on all three of my machines with 2.9.4. Quite a while ago, I updated the wiki for remote pendant including .hal files you can include.

GUI that somewhat resembles haas or fanuc workflow.

Category: General LinuxCNC Questions

You don't need to make a custom keyboard, a standard keyboard has losts of "useless" keys which you can repurpose for your needs.

 

"Need" has nothing to do with it.  GUI's and physical interfaces are deep in to the realm of personal preference... so there is no right answer for everyone.

If a body wants a user interface - screen and physical - which mimics typical industrial control panels then there is a certain layout, workflow, and feature-set they're likely to prefer.

I suspect that repurposing some keys on a standard keyboard is unlikely to tickle thier fancy.

Of course, everything I've posted above is based on my own preferences regarding CNC interfaces.
