EtherCAT master xml file for Yaskawa Sigma Servo motor?

Category: EtherCAT

Good. EoE has to go.

But you see automata's posts here? Do not be surprised if it still does not work.
Thankfully, automata has kindly posted the solution here.
Please report back how it goes and if there are problems with lcec
I hope automata will guide you to use his solution.

LatheEasyStep – experimental QtVCP macro for step-by-step lathe programming

Category: Qtvcp

Do you already know Andy's lathe macros?
forum.linuxcnc.org/41-guis/26550-lathe-macros
The graphical interface is fantastic.

Rather than reinventing the wheel, have you considered what it is which you are adding with you macros? Maybe you can coordinate with Andy to make them even more awesome.
Cheers,
Mark

Mesa 6i25 not working?

Category: Driver Boards

I just switched to default jumper positions:
W1 DOWN
W2 DOWN
W3 UP
W4 UP
W5 UP
W7 DOWN
W8 UP

Result is still the same:
user@denc:~$ mesaflash --device 6I25
No 6I25 board found
user@denc:~$ mesaflash --device 5I25
No 5I25 board found

dmesg and lspci outputs are provided.

Mesa 6i25 not working?

Category: Driver Boards

That will likely not work, (not meet timing) you must jumper the card for 5I25 mode to use 5I25 firmware (the default)

But it is 6I25, not 5I25. 



Jumpers are:
W1 DOWN
W2 DOWN
W3 DOWN
W4 UP
W5 UP
W7 UP
W8 UP

And it reports 66MHz.

DIY CNC Mill - Random Limit Switch Errors

Category: Milling Machines

I forgot to mention, VFDs radiate interference out of both incoming and outgoing power wires. Outgoing is by far the worst, but incoming side also quite bad. Thanks for the BOB picture. I circled the power wires going past BOB. Those certainly radiate interference when the VFD is running, everything all the way back to the breaker panel and beyond is affected to a certain extent. I prefer to keep all that AC wiring a minimum of 12" from the BOB.

How long is your parallel port cable? Is it shielded? The longer it is, the more interference it can collect. If it is shielded then I would think no worry.

asd-a2-e ... lcec driver?

Category: EtherCAT

Best you make sure that your drive is indeed an Ethercat drive first of all.

If so, I think you can try this small example.
github.com/dbraun1981/hal-cia402/tree/main/example
I wouldn't be surprised if it works.
Some drives need some additional settings, if you are lucky yours will run directly.
Anyway, this little example shows the structure of how to connect an Ethercat servo drive to LinuxCNC.

The encoder position is used internally in the drive for feedback.
The encoder position is feed back to linuxcnc also, see the example hal file.
After you get it going, you should tune the drive's PID parameters,
just like is needed for every servo drive.

CNC Rotary Table with Standalone Controller for Gear Hobbing

Category: Basic Configuration

Just a few thoughts.

If for professional production, take it with a lot of caution. :-) I only toyed around for hobby use.

300 rpm is fairly quick for a rotary axis. :-)
How fast can the hob run during the cut?
The machine can tilt the spindle, can it?
You do not really need the spindle position, under the condition that the spindle is brought up to speed, before you start the cut and not stopped before it is finished.
A simple incremental encoder on the spindle probably works fine. More than 100 counts per rev and it might already work.
I run the rotary open loop, as long as the motor can keep up with torque and speed, encoder on the rotary is "nice to have", but not essential.

You can even get away with a semi electronic gearing :-) for straight gears this will get rid of the computer altogether.


There is (was) an instruction on the Linux Wiki where the gear hobbing was explained.
wiki.linuxcnc.org/cgi-bin/wiki.pl?Hobbing

The spindle syncronisation is independent from x-y-z axis, as long as you do not. a) want to cut helical gears b) want to run hob shifting c) want to try hobbing wormgears with tangential hobbing.

EtherCAT master xml file for Yaskawa Sigma Servo motor?

Category: EtherCAT

Thank you so much, Mr.Hakan.

I installed "go" package and then everything seems to be successful.

I appreciate your kindness.

I will try to connec YASKAWA Servo tomorrow.

I have thought of it but i havent the skills yet to build a new driver ..
the drive is
cdn.delta-emea.com/cs/download/file/4641...2_UM_EN_20201209.pdf

Ok is CSP mode only motor encoder ? i am not sure at all now..

when i started the build i planned to use
6.2.1 Position Command in PT Mode
Becurse of the feedback from the scale :)

Following error due 2³¹ 2 147 483 648 jump to -2 147 483 648

Category: EtherCAT

you have to adjust the resolution over SDOs during start up and then to reduce it over float factor in the SMs ... if you are scaling 1 / something big it will just create you crazy numbers then ... 

share config at first place ... then we can help you well

MonoKrom - QtPyVCP GUI for PlasmaC and Mill

Category: QtPyVCP

Okay it is possible to pre-process the g-code manually like this:

1) Launch an instance of Monokrom (sim)
2) Navigate to the Monokrom Simulation Config Directory. Open terminal there and set environment variables
~/linuxcnc/configs/sim.monokrom/plasmac$ export CONFIG_DIR=$(pwd)
~/linuxcnc/configs/sim.monokrom/plasmac$ export INI_FILE_NAME=$(pwd)/xyz.ini

3) Call preprocessor in terminal with the input.ngc processed by the SheetCam PlasmaC Post
~/linuxcnc/configs/sim.monokrom/plasmac$ python3 plasma_gcode_preprocessor.py input.ngc > processed.ngc

The output is the processed.ngc. The first few lines are below:
Filter name: from-ini func: <function from_ini at 0x7ff0a03176a0>
(--------------------------------------------------)
(            Plasma G-Code Preprocessor            )
(                 00.30                            )
(--------------------------------------------------)
;inputs
#<ucs_x_offset> = [#5221 + [[#5220-1] * 20]]
#<ucs_y_offset> = [#5222 + [[#5220-1] * 20]]
#<ucs_r_offset> = [#5230 + [[#5220-1] * 20]]
#<array_x_offset> = 0.0
#<array_y_offset> = 0.0
#<array_columns> = 1
#<array_rows> = 1
...

This is why I get the error in input.ngc line 1: Unknown word where unary operation could be. The first line contains "Filter name: from-ini func: <function from_ini at 0x7ff0a03176a0>".
