Touch off don`t work "file not open"

Category: AXIS 

[RS274NGC]
PARAMETER_FILE = linuxcnc.var
 
I use clean configuration created by PNCCONF.
My linuxcnc version is 2.10

If I don't enter anything from the keyboard and just press the OK button in the window, the coordinates are reset.
but if I enter any number, the option to confirm with the OK button disappears.

After I click the OK button, I open the linuxcnc.var file and see that the values have been written
5221    37.000000
5222    0.000000
5223    -10.443750
 
But if I enter any number from the keyboard, the option to confirm disappears, and I see the inscription "File not open"

Interfaces & linear scale for LinuxCNC

Category: General LinuxCNC Questions

Hi,
I originally wanted to run a cheap DIY cnc machine using an old Intel Atom dualcore computer which has an LPT connector. But meanwhile I start thinking about higher quality components.

Same specs:
-stepper motors (already exist)
-linear rails for a work area of 1000/600/200mm (already exist)
-spindle Kress FME800 (already exists)
-stepper driver board with 5x Toshiba TB6560 (already exists)
-USB connected hand controller/job wheel LHB04 (already exists)

Now I wonder if I'd better go for an network/USB controlled Mesa card to get rid of that old Intel Atom computer and be able to use any machine (probably a modern notebook).

Also I would like to bux linear scales for my build, but couldn't figure out how they would be connected to LinuxCNC.
Is there a lis with reliable (but not too expensive) supportet linear scales?

And would you rather ust the Toshiba stepper driver board listet above or get some modern alternative?

Since I didn't really start building it, I'm free to change components for the good :)

I'm going to weld the frame for my machine. So I wonder what's the best way to start? At the moment I think I'm going to build z-axis first and depending on it's dimensions I can design the x-axis, then Y-axis.
But for designing the z-axis I need to know which linear scale system I need to mount and what size it is.

Since this CNC machine is intended to build electrical guitars, I don't require the highest precision, but I'd like to have as small tollerances as possilbe for a reliable pricetag.
