So basically if you select piercing only
1-Make  piercing. 
2- Ask the operator to clean dross.
3 - Ask the operators to change consumables (if the case).
4 - Start cutting with 0 piercing delay.

I use a separate material config for piercing and switch to normal when cutting.
Going a bit further, one could have automatic shift to a piercing-only material config when doing piercing only.
And shift back afterwards.

I'm not good at typical programming languages. I'm best at G-code.

Here, G4 has to be because after reaching the pocket, the READY pin is active so the toolchange procedure runs without moving the engine

Yes, I know that ATC is not a priority, but I'm asking in advance (I'll eventually write ATC on CL .. I think that thanks to the knowledge I've gained from trying to start CAROUSEL, I'll manage, and if not, I'll treat it as an axis and use g-code)

This machine is a challenge because:
I've never used a tool magazine
I've never done anything on servos
I didn't have a Mesa card either
and here it will be all

As you have it it is way to long so it limits the max velocity a lot and can cause joint errors, depending on the scale and velocity set in the ini file.

need this???

DIRHOLD = 150000

same of the conf with:

#DIRHOLD = 150000
#STEPLEN = 5000
#STEPSPACE = 5000

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

I will try this, note that this is a difference from LinuxCNCs standard TP where the
acceleration bound in the ini file is obeyed at all points.
(unless you have backlash compensation enabled)

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

[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_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.

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

please post your ini file.

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.
