Zero Pierce delay After pierce Only was created by grijalvap

Zero Pierce delay After pierce Only

Category: Plasmac

Hi, yesterday I used the Pierce only funtion in  1 inch plate, it worked very well, I saw the inconvenient of having to edit the file to change pierce delay to 0.0 after pierce only. 
I wonder if we can have a control to override the pierce delay vaule and make it zero, maybe the same button that changes from Normal Cut to Pierce Only can has the funtions Normal Cut - Pierce Only - After Pierce.

Any idea why such a long delay between pressing a button and the actual move?

Yes i have, but not a default config, it is for NV something or another.
Do you get the dropped connection?
Do you get joint errors?

In your ini file, you have limited max_output to 8, should usually be 10.
Here is a detailed tuning guide:

Do read it fully first so you know what parts to pay more attention, no skipping steps.
And do let me know if something there can be explained better.

Is there a bug in the carousel component or am I doing it wrong ATC Denford

Category: Advanced Configuration

Hello, I'm starting to restore a lathe from scrap.


My problem is ATC (we'll get to the original ATC when I start the model)
Test model:
Step PIN8 dir PIN9 LPT stepper motor
Microstep 1600
4 pockets
1 gome sensor (pocket 1)
Head lock by left rotation (example video from the web)

Component linuxcnc.org/docs/html/man/man9/carousel.9.html
Basic lathe configuration

Symptoms:

T1M6 after starting linuxcnc looks for HOME and rewinds (strangely but it does rewind)
Each successive tool, e.g. T3M6, no longer rewinds
When I start from T2 M6 it passes HOME (activating it) but no longer rewinds while in position

My observations:
Dir changes but there is no movement. which means that there are no pulses flowing to PIN 8.
M66 waits for READY signal even though nothing is happening. Only after time has elapsed does the DIR state change and then it is READY

I seem to of been wrong about converting the ST-link to DAP. I just went back and watched the video again and there were originally 2 steps in doing the conversion, but there is the post below that video - forum.linuxcnc.org/18-computer/44828-rem...rd?start=2050#321860 - that says to just use that one file?

I am now very confused and the computer says the converted ST link is an unrecognized device and it does not show up. I can not communicate with the link plugged into the USB

At this point I truly do not know what to do.

Yes, excellent tool , but I can't create a spindle configuration with a servo motor drive (step-dir chinese servo T3D) using CT2 - I was hoping that pnconfig knew that.

I'm afraid I don't have enough knowledge to manually insert component lines into an already created configuration file (CT2).

Basic homing and CW/CW rotation indexing working fine now!
Altough it responds with a small delay (due to the stepgen PCB)

Some vids:






Next step is mapping and wiring the other sensors!

No, not yet.
Now is that point where you upload your configuration files here so we can have a look, joint errors are usually miss configuration on stepper systems.
What board are you using?

Hi tommylight, have you seen my configuration? is a default conf.

How to change jog speed using joystick buttons (QtDragon + HAL)?

Category: HAL

Hi everyone,I'm using QtDragon and a joystick (via
hal_input
) to jog my machine. Jogging works fine with a costant speed, but I’d like to adjust the jog speed using two buttons — one to increase and one to decrease the speed. (like the slider in the Qtdragon gui)

Sorry so slow but massive interruptions and a few train wrecks to clean up...

I have the 7i95t working completly now and would like to share what I've learned about getting this board to work with linuxcnc 2.10pre. MesaCT tool 2.1.7 doesn't currently support the 7i95t
 

I just ran MesaCT 2.1.7 and pressed two buttons and created a working configuration for a 7i95T.

Pcw,

Thanks again for your effort.

What do you advise at this moment?
You can tune the planner with scurve jerk value in the hal section. This changes the accelation profile.
This jerk value is not integrated to the .ini file so far.

I assume you could tune your ini config to run without following error? Or is this not the case?

Indeed if you set acceleration to 200, the scurve max acceleration will be 400 at inflection point.
Exceeding your max acc off 240.

AC Servo tuning - Joint 0 following error at high velocities

Category: Basic Configuration

Thanks for your quick reply.

I haven't changed any drive parameters.

Since i am new to Servo tuning, its quite confusing to conclude, whatever i am doing is correct or not. Now i have a fundamental question,

With the above setup is it possible to achieve 15,000 mm/min feedrate within 20 micron positional accuracy and +- 20 micron repeatability? I doubt whether the control loop is fast enough to reach this speed and accuracy ?
