Position: relative expected

Hi,
I'm trying to run a little test program, and it aborts with the fault message: 'Motor 0 Positionssfehler (sic!) Position: relativ erwartet' ('motor 0 positioning error position: relative expected').
The program is this:

%
(G90: Set to Absolute Positioning)
G90
(G94: Feed Rate Mode Units per Minute)
G94
(G17: Select XY plane for arc moves for G2 G3)
G17
(G21: Set Units to Millimeters)
G21
(G54: Select coordinate system 1)
G54

G1 X0 Y0 F1000
G1 X10 Y0
G1 X10 Y10
G1 X0 Y10
G1 X0 Y0

M30
%

I'm a bit surprised since I'm setting G90. What am I doing wrong?

Thanks!

P.S. little typo: 'Positionssfehler' should be 'Positionsfehler'

Seems that there may actually be two printouts on the same line: which comes from motion which seems to come from the Axis GUI:

You are not giving us much else to go on. Are you getting getting following errors on joint 0 when using other Gcode or is it only with this particular program?

I haven't tried any other program. This was my first test and I made it as basic as possible.
Could there be something in the .hal or .ini that makes it expect relative positions?
What information do you need?

Does axis jogging work?
If you issue an MDI command (eg 'G1 x10 f1000') do you get a ''Motor 0 Positionssfehler'? If so try to lower the feed rate (eg 'G1 x10 f10').

Impossible to troubleshoot further without knowing more about your configuration so post your hal and ini files.

Sorry for the late reply.

Well, I should have respected the wisdom of the ancients: 'have you tried turning it off and on again?'.

I tried the MDI command and it worked. Then I reloaded the program and it worked, too. Nothing changed, just a reboot between the tries.

Thanks for your support!

I'm pretty sure Tommy would disagree with that, personally I've never had any issues with HP gear, even the ancient server I was running 24/7.
I'd say that there are quite a few HP machines running Linuxcnc that never give any issues.

Oh yes, i did disagree with that statement, silently, as he might have experience with "Home" or "Office" types of HP computers and those are frankly cr@p, but "Enterprise" HP computers and workstations are magnificent in every way and some have 700W or 1000W power supplies despite no way of cramming stuff in it to require that kind of power. Same goes for Dell and Lenovo and Fujitsu and older Fujitsu-Siemens, all of those in the "Enterprise" edition work perfectly, no matter how old, and using them 24/7 is a given.
And yes, there are many of us here using HP even on industrial machines, as again, they never fail.

HP 800 G2 SFF and HP 800 G3 SFF with Intel network are perfect with Mesa cards. No issues, except replacing a noisy CPU fan

MaHa, why you up so early?
4:40AM here, going to bed right now.
And whatever the reason you are up so early, i hope it's a good one.

I was completing and testing my new parameter subroutine for helical inside or outside contour ramp, adjustable stepover and x/y/z allowance finishing cut. Took the whole night to iron out some misbehaviour
