Ich habe so etwas nicht. Und bei mir funktionieren zwei Browser nicht. Handy und Tablet gehen auch nicht.  

 

I am using a milling maschine, i am New to linuxcnc and the editing of files , ist that possibly the problem that i User the default files ?

I got it work with a own component to make 1 move from position to position forwaes with lock backward and reduce pwm.

But the turret can only travel to next position in forward.

If i am on tool 5 and i want tool 1.. i need 2 times the move.
Is it possible to do this in the component with a abs function?

what i mean... i must handle the rollover=

presenttoolslots 6
currenttool is 6
calledtool is 1
Turretmoves = calledtool - currenttool = -5
Commandedmoves= presenttoolslots - (abs) turretmoves

next step is the to count every move.
moved = i++
if moved == commandedmoves
toolchange done

Sounds ok?!

I do the coordination of the forward and backward stuff with 2 time delays. On the end i set the pwm value lower to lock agoinst the pawl with lower current to not blow the dc motor.




Thanks

Based on the data provided, if the motor is a permanent magnet type, it is likely in the range of approximately 7.5 kW (or max 11 kW)

From the peak data shared, I estimate that the motor’s rated current at stall torque would be around 50A. Accordingly, you may need to consider a universal drive rated at approximately 50A.. This will be around 22kw

Can you verify whether the motor nameplate specifies a rated voltage 400V, or is this value being assumed based on the drive input power?

Got my first cuts made with it today, took a while to get the gcode to work correctly with qt plasma c
We also added a image to dxf function, still needs some work but its a start. 
I added a kerf width calculation wizard... cut out a test piece input the actual cut size vs the wanted cut size and it calculates what your kerf width is spoused to be. I did a install on a friends computer and some of the install seems broken, need to make it more shareable if anyone else wants to easily use it. Not to shabby tho for only being 2 weeks into the project part time.

i have here a l298n modul and a mesa 7i92 with bitfile adjusted to have pwm and 2 gpios for setting direction.

You could start by having a look at the "etch a sketch" config included with LinuxCNC, it is for parallel port so needs changing pin names to Mesa, and it is for L298.
Probably doing some timing stuff in hal using timedelay and/or oneshot and maybe flip-flop ....

Reading something today. Maybe try using smp affinity to lock the USB interrupt to  Core1 (away from core 0 housekeeping) and assuming > 2 cores. You can find the interrupt by
cat /proc/interrupts | grep -i usb

Then follow one of the many posts about cpu affinity for networking. Just remember you need to reset this on every boot.

I use "dark reader" and since 3 days ago it does not allow me to reply to anything here without disabling it.

Yes and no, sorry my bad, i thought i uploaded the new config there, so thank you for reminding me.
I did upload the new config there and added some more info at the top, so have a look at your own leisure.
These are also new machines i have built and use the same configs for PWM and here i did upload the new configs.
forum.linuxcnc.org/show-your-stuff/46752...ver-etcher-scratcher

Latest config with provisions for disabling PWM on program pause or stop and enabling on resume.
Edit:
Attached the latest config to the first post, also.

Tommy are you talking about the engravertest.zip?

Ich habe keine Add-ons installiert und das Design nicht verändert. 

Firefox und Microsoft Edge haben beide den gleichen Fehler. 

Was meinst du? 

Sorry but i do not have any file you need, i would have attached them on my first reply if i did.

In the ini file
HOME_OFFSET = -3
for each joint/axis
That is for metric machine, adjust accordingly for imperial.
