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

Solid core wire is generally more manageable than stranded wire.

Random Joke:
What did one wire say to the other?
"Help! I'm stranded!"

Looks good, but perhaps without some of the original charm.

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



the work is linuxcnc classic engrave test

Nice clean up.

Problem 1: gelöst

Wie hast du das Problem gelöst?
Ich habe den gleichen Fehler.

Eugenius.

I also want to be able to home them independently when I want.

Yes, set the same home sequence for both in the ini file.

please post your ini file.

Don't worry about the toolchanger until the rest of the machine works.

It's not a 100% essential component.

How do the buttons communicate with the PC?

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.

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.

 

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.
 

The X and Y axes each have a home switch that is wired separately.

Both axes can be homed without issue.

However, I can only home one axis at a time.

Why can't I home both the X axis and the Y axis simulataneously?

I'm using the AXIS GUI.

Pressing Ctrl+Home should home all axes, according to the quick reference; but for me it unhomes all axes!

The switches are independent.

I also have a Z axis that currently has no home switch (There are wires so I can add one later on, however).
