10.5 x 25 cnc plasma table retrofit

Category: Computers and Hardware

120watt is too low i think.
I plan to build a machine like this and am thinking to put 2 x 750w for y axis 1x750w x axis 1x600w z axis.
With servobelt transmission system with std s5m belts.

I use this calculator to calculate the parameters for the THC.

Can you check to see if it is accurate please?

The message about 'undefined symbol: kinematicsSwitch' is actually a spurious error that will pop up whenever the kinematic fails to load.
I believe the actual problem is:

rtapi_app: caught signal 11 - dumping core

which unfortunately is a bit cryptic.

I would start out with an unmodified 'xyzcb_tdr_kins.comp' and do the modifications in small steps while frequently 'halcompiling' the file to find out when it breaks.

lost frames issue

Category: EtherCAT

i keep losing frames while operating the machine which affects the smoothness of the motion i dont know what should i do or look for to fix this issue i thought it might have been the cables so i got new ones but the issue still remains any help would be appreciated

Plausiblty check on feedrates

Category: General LinuxCNC Questions

This weekend I again trashed a tool (luckily only a drill), but using an F50 (Expecting G94 50 mm/min) while in G95 mode. (at about 38:45...)

I have heard the some other controllers allow setting an error trigger if the feedrate exceeds a set threshold. I went searching if LinuxCNC offers an option to set a max feedrate it will error out on in G95 (would also make sense to have a min feedrate error message in G94, as I have also had F0.01, and then wondered why the machine didn't seem to move). I didnt find these options. Am I missing something or they really dont exist?
Cheer,
Mark

Hi Tommy,

i think i never used the lower case "s". I used the millturn.comp for this function. Here is the part from my comp file:

EXPORT_SYMBOL(kinematicsType);
EXPORT_SYMBOL(kinematicsSwitchable);
EXPORT_SYMBOL(kinematicsSwitch);
EXPORT_SYMBOL(kinematicsInverse);
EXPORT_SYMBOL(kinematicsForward);

static hal_u32_t switchkins_type;

int kinematicsSwitchable() {return 1;}

int kinematicsSwitch(int new_switchkins_type)
{
switchkins_type = new_switchkins_type;
rtapi_print("kinematicsSwitch(): type=%d\n",switchkins_type);
// create case structure for switchable kinematics
switch (switchkins_type)
{
case 0: rtapi_print_msg(RTAPI_MSG_INFO,
"kinematicsSwitch:TYPE0\n");
*haldata->kinstype_is_0 = 1;
*haldata->kinstype_is_1 = 0;
break;
case 1: rtapi_print_msg(RTAPI_MSG_INFO,
"kinematicsSwitch:TYPE1\n");
*haldata->kinstype_is_0 = 0;
*haldata->kinstype_is_1 = 1;
break;
default: rtapi_print_msg(RTAPI_MSG_ERR,
"kinematicsSwitch:BAD VALUE <%d>\n",
switchkins_type);
*haldata->kinstype_is_1 = 0;
*haldata->kinstype_is_0 = 0;
return -1; // FAIL
}
return 0; // ok
}

You need to plot the voltage or encoder with halscope. I think that is way too low. I would expect around 130 volts. I suspect the THCAD is not properly calibrated. The plot will tell you how long to delay. I would check the input voltage at the thcad with a multimeter.

I did have a machine once that needed about 2 seconds to be stable...

motmod: dlopen: /usr/lib/linuxcnc/modules/motmod.so: undefined symbol: kinematicsSwitch

Linux is case sensitive, so kinematicsswitch is not the same as kinematicsSwitch, notice the upper case S.

This will not work for the Pi because the buildbot does not build Debs for it.
Your only option is to compile from source.

It is a new machine. The divider is set to 1/32. I am not sure what voltage is given by the source as this is also a new configuration Hypertherm that does stuff automatically. It reads the consumable and does it's own adjustments. Although I disabled that feature on the plasma source. It might still be doing something that I am not aware off.
The voltage seems very stable . The thing that bothers me is that the torch starts moving up as soon as it starts cutting. It does not delay the 5 seconds that I set the THC_delay to.

Additionally i created another bare bone config with step conf and just replaced the KINEMATICS Name in the .ini file with my kinematic file. (It starts up with a 5 axis demo kinematics file, just not with mine) I assume there is something wrong in my kinematics ?

Problem with THC

Category: Plasmac

Use halscope to do a plot of encoder.0.velocity pin during a pierce, might be interference, although as you are getting 55 and 75V readings it also seems not right, and this might be due to scaling and/or due to interference.
What divider ratio is Mesa THCAD set to? Usually 1/32.
If this is a new machine, disable auto volts, disable void lock and velocity lock, well disable everything automated until you get the machine working correctly, only then enable the automation.
