Can I home X and Y axes simultaneously?

Category: General LinuxCNC Questions

From the "machine" menu, choose "homing" then the axis you want to home.

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?
 

No the connection is stable( joint error only 3 video Youtube+stresstest+rustdesk remote desktop) but i have bad stepper movement.
Try to put:
[JOINT_1]
DIRSETUP   = 150000
DIRHOLD    = 150000
STEPLEN    = 150000
STEPSPACE  = 150000

 and

[STEPGEN]
#150000
DIRSETUP   = 150000
DIRHOLD    = 150000
STEPLEN    = 150000
STEPSPACE  = 150000

and
[STEPGEN]
#150000
STEPGEN_DIRSETUP   = 150000
STEPGEN_DIRHOLD    = 150000
STEPGEN_STEPLEN    = 150000
STEPGEN_STEPSPACE  = 150000

and 

[STEPGEN]
#150000
STEPGEN_1_DIRSETUP   = 150000
STEPGEN_1_DIRHOLD    = 150000
STEPGEN_1_STEPLEN    = 150000
STEPGEN_1_STEPSPACE  = 150000

my driver is a  TB6560 (only for testing not final hardware)
all conf not change the movement

I think it has to do with the 10 bucks stepgen PCB, it also happened before I removed the physical pushbuttons and soldered wires to it.

It's not a big issue, but would be nice if it responds faster.

I have to double check the stepper driver dip switch settings.
If no luck i think it might be possible to put a relay on the EN+/- wire, between the PCB and the stepper driver and just leave the PCB ON constantly, only changing direction by switching the DIR and activating the stepper driver via the Enabled signal.
That could solve it, will test later on. It would send out pulse signal constantly, but can't think of a reason why that would be an issue.

AC Servo tuning - Joint 0 following error at high velocities

Category: Basic Configuration

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 ?

The main control loop in this case is in the drive, its velocity feedback loop.
The position control loop in LinuxCNC can run more slowly and maintain
high accuracy and repeatability. Note that at 15000 mm/m you move only 250
microns per ms, so it takes only relatively crude velocity commands to keep
within 20 microns. Note that as you increase acceleration, tuning becomes more
difficult as you run into various physical limits.

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?

In your ini file, you have limited max_output to 8, should usually be 10.
Here is a detailed tuning guide:
forum.linuxcnc.org/10-advanced-configura...ning-detailed-how-to
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 was created by Adam Maszynotwór

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.
