case 1: // Gear E
gear = (high_gear != 0) ? 5 : 10;
break;

Should it not be like this then? Hi gear is 5 and Lo gear is 10 right?

setp gearblocker.0.gear.10.min-speed 80

Sure somebody will correct us ;)

Think you found a bug there.
This is one of those areas where it is soo easy to make a problem. Index starting at 0 or 1.
Uhhm. I think you can replace the whole case-switch block with
Code:
gear = input_1 + 2*input_B + 3*input_C + 4*input_D + 5*input_E + 5*high_gear -1;
This will directly calculate the engaged gear. You promise only one of the input_ABCDE is engaged at any given time?
The -1 is to make the indexing into speed_max, etc zero-based.

You can test in a hal file to see if the syntax is correct.
But there are no pins called what you write above. Didn't it work in the way I wrote it?

On holiday and on the phone, so quoting is difficult.

The gears probably are switched,yes. As i explained I did it at lunchtime in a widows pc at work. It is entirely untested.

There are other ways to do it. I chose the switch block to explicitly reject invalid gear selections.
The single line calculation returns gear 5 if both B and C are selected. And that seems something to reject.

So down in my shop and trying to install linuxcnc-dev but no-go in my Mint installation. Need to get my comp file working.

Any clues what can be wrong?

sudo apt-get install linuxcnc-dev is what I try to use
