Machine plasma torch IPTM-80 and ohmic sensor

Category: Plasmac

You have to compare with the data sheet of the recom www.tme.eu/Document/cd1b5f2ae4e38e422d024220d341ab42/RS3KZ.pdf
It looks like Ctrl is reversed? Apply voltage to switch off? Or am I wrong. One want the module to be off and actively switch on.

[SOLVED] "syntax error in VERSION script" compiling kins with Halcompile.

Category: Advanced Configuration

I have found a solution to the problem often seen when trying to compile Kinematics (or occasionally other) modules  from C-code with halcompile.

Solution:

Make sure that the .c file contains the following code and the problem should be solved.
#include "rtapi_app.h"

This requires the file to supply an app_main and exit:
int comp_id;
int rtapi_app_main(void) {
    comp_id = hal_init("bipodkins");
    hal_ready(comp_id);
    return comp_id;
}

void rtapi_app_exit(void)
{
  hal_exit(comp_id);
}

Explanation

Halcompile creates a Makefile to compile the component. This includes Makefile.modinc

Makefile.modinc contains this code:
    $(Q)objdump -w -j .rtapi_export -t $*.tmp \
    | awk 'BEGIN{print "{ global :"} /rtapi_exported_/{printf("%s;\n", substr($$6,16))} END{print "local : * ; };"}' \
    > $*.ver

Which is what creates the modulename.ver file that the complaint is about. Without #include "rtapi_app.h" the .rtapi_export section doesn't exist, so the .ver file is invalid.

Adding the header is enough to complile the module, but it will then fail to load without an rtapi_app_main()

Seeking best practice advices for precision double side machining

Category: CAD CAM

It wouldn't have anything to do with jaw lift when tightening the vice ?
Does the fixture support the stock fully along the side that is contact or have you allowed for a "hollow" in the middle of the design of the part and fixture allows for this.

Proposal RPi Linuxcnc Image Based on Raspi OS All welcome/encoraged to comment

Category: Installing LinuxCNC

I'll need your advice regarding setting up Ethercat repos Rod, and whether a 6.12.34 kernel is supported. As I kept to the RPi rt kernel from their repo. And one kernel supports both the 4 and 5.

Machine plasma torch IPTM-80 and ohmic sensor

Category: Plasmac

I only found this recom dc-dc converter and bought it from tme.eu
www.tme.eu/en/details/rs3k-2424sz_h3/dc-dc-converters/recom/
I see that Mouser, Digikey, Farnell and those big ones have the item.
Can't find it on cheap places ebay, alix etc.

RaspberryPi 4/5 Ethercat Rtelligent ECT60 Synchronization error

Category: EtherCAT

I'm not too sure if this may help
github.com/MichaIng/DietPi/issues/6577

The power saving feature shouldn't be kicking whilst there is traffic, but stranger things do happen. And I know the RPi is on a later kernel.
Actually that reminds me I'll have to talk to Rod about Ethercat repos for the new image.

Machine plasma torch IPTM-80 and ohmic sensor

Category: Plasmac

I'm not good at electronics. i will try implement a hypersensing circuit from plasma-cnc-primer docs with yours schematic. similarly, without surgery in a long cable.

for ohmic sense i only have thcad-10. i have thcad-300 but i used it for THC in this plasma cutter with 1:1 devider.

I found almost all the components (FY0022 + FY0023 connector,24VDC >20A relay ). but i can't find Isolated dc-dc converter with on/off signal.

Try to activate Gladevcp with setp gladevcp -> Linuxcnc

Category: GladeVCP

Hello,
i try to activate some glade functions. Therefore i use "gladevcp.table1 1" in my custom_postgui.hal.
In the attached file i deactivated "gladevcp.table1 1". Then you can see the light grey button/leds but you can´t use them. If activated you just see a blank site.

RaspberryPi 4/5 Ethercat Rtelligent ECT60 Synchronization error

Category: EtherCAT

Well, I don't have a pi with linuxcnc and only googled a bit.
forums.raspberrypi.com/viewtopic.php?t=362866#p2229969 worth a try I guess if you haven't done so.

Joint 2 on limit switch error -> Z Axis

There was "A Maximum Limit + Home set" instead of "Z Maximum Limit + Home"

RaspberryPi 4/5 Ethercat Rtelligent ECT60 Synchronization error

Category: EtherCAT

May be I have found least workaround and some glue what's wrong. I tested adding ethernet switch between my Raspberry Pi 5 and ETC60 Ethercat stepper controller. After adding this switch i have not got any synchronization errors or got Raspberry ethernet link up/down causing that error.

Because i have got same error between multiple tested Raspbelly Pi 4 and 5 boards and least three controller boxes having Rtlligent ETC60it cant be just a faulty unit but more common compatibility issue. Least adding switch is workaround fix.

My general experience from Linuxcnc / Ethercat / ECT60 is very positive. First I replaced always failing PC hardware with Raspberry Pi and PIO controlled steppers but I wanted better and Ethercat felt best choice. In beginning i needed to build everything from sources. This joint x motion error / synhcronization error was only unresolved issue and it took long time to find out that it was not caused by other factors like insufficient real time performance.Now when everything works and there is easy installation package i think that it will be my number one option. Next I will try Lichuan Ethercat servo and lets see is do I need switch between Lichuan ethervcat controller or not

Major update 1 Nov 2025

First image I feel is suitable for testing.

Linuxcnc 2.9.7 is pulled from the Linuxcnc repos.


 

Thats pretty cool!
