Parport Base Address and Launch my mill app (using Virtual Box, no mill, etc)

Hello Seniors,
I am new to the scene of Linuxcnc, I'm having issue with the parport base address is 0 where launching my config produces an error but now it freezes (trying 0x378 freezes my virtual box), the output pinout is Xylotex. The rest of the setup is default excluding the table for x, y where it is from -12 to 12. The max velocity is 10in/s. is there a default address I'm suppose to be using or am I doing something wrong?

virtualö BOX is no Realtime
USE a Realtime Kernal
YOU can RUN Your Mashine on the DVD

for parport adress use
dmesg | grep parpo*
[ 9.087803] parport_pc 00:01: reported by Plug and Play ACPI
[ 9.087875] parport0: PC-style at 0x378, irq 7 [PCSPP,TRISTATE]
[ 9.188196] lp0: using parport0 (interrupt-driven).

It will not work in Virtualbox.
You can run simulations in Virtualbox, but controlling real hardware is not possible.
It is locking up because Virtualbox can't access the non existent address 0x378.

Run the Linuxcnc on bare hardware and it will work.

0x378 is the normal default address for a PC's built in parallel port. If your PC has a built in port that is probably the right address. If you are using an add in PCI or PCIe parallel port card, then the address will be something different that you will need to look up.

The thing is that I only want to run the simulations, but keeping the parport at 0 doesn't run the my-mill app or setting the parport freezes my virtual box.

Actually come to think of it, on my installation of Virutalbox (v5.2.12) running in Windows7 does not freeze when starting a "real" parallel port config in Linuxcnc (v2.7). It does set alarms saying that ports can't be found, but the Axis window opens. After that you can't do much because the non existent machine can't be taken out of e-stop or homed but... Not sure why your system might be freezing.

Can you open and run simulation configs in Virtualbox?

I can run the default configs when opening up linuxcnc, but when using the step-config thats when I have an issue and problems.

@Michael Chan,

If you want only to run simulation's you don't need a parport config at all.
You actually need a simulation configuration to test your machine output.

The axis config's has a simulation version (standard). This ini and hal config's can be used and can modified all over the linux sources.
It works with Gscreen, Gmocappy, etc. It even works with Ethercat (the fastest protocol). Because linuxcnc is written to be compatible.

Are you running a virtual box in windows? So yes, why?

tbh, I'm just rather not deal with linux on my laptop, but should probably get in on my laptop, if this is the case. As for why, well I was planning on just messing around with the simulations, but wanted to try other things out. Then this happen, so my bad. also Oof.

In window's you can do certain things, but not very much things, like command line command's like sudo.
Sudo mean's power. If you type : ping forum.linuxcnc.org
you get :
4 packets transmitted, 4 packets received, 0% packet loss
round-trip min/avg/max/stddev = 99.633/99.945/100.309/0.244 ms

If you type sudo before, you are in the endless loop.
So keep in mind. Once you start with linux, you will stay there if you are curious about linux.
Within 10 year's window's will not be used anymore. Who has a nokia phone today? Nokia and window's lost the battle.

Stepconfig can create simulation configs as well. (on the first Stepconf window there is a check box for create simulation.)
