LinuxCNC 2.9.0 configuration problem

Hallo guys

have LinuxCNC version 2.9.0 working properly on XYZ configuration.
However when I try to add the A-axis (configuration XYZA) I get the following problem (see attachment)

The failure window appears after the configuration of the Z axis; I'm not able to enter the A-axis config

Does somebody have any idea ? All float parameters seem to be ok where they are required

Also noticed there is only a general setup for the unit (mm/inch). How to set a rotary unit (deg) for A axis ?
Note: A axis is not a spindle, is needed for a given rotation only, thus it would be nice to have it's reference position in deg (this is not really necessary because with the scaling in the axis definition you can set the corresponding rotation in function of mm value)

Thanks for sharing

Can you post the working xyz you started with?

I meant to add the pncconf file is what I need (ends with .pncconf)

Never mind I can confirm the error...

I have a work around:
in the .pnnconf file of the original XYZ file open in a text editor and look for the line:change it to :Save the file and it will now get past the Z page.

I'll look into a fix and look into the angular/linear problem for the A axis.

Thanks for the report
Chris

I pushed a (hopeful) fix for both problems, if you use a RIP it's available now, if an installed version in a few hours.

Chris

Will give a try...

Thanks Chris

Hi Chris,

the modification of the .Pncconfig works fine, now the A-axis can be configured (general Axis and Motor parameters have the right units).
Great job !
this must be done every time the configuration is modified ?

Have some other suggestions for the config (see attachments):

1) beside the mm/inch choice for the linear movement a deg/rad for the A axis could be foreseen (nice to have)


2) display geometry definition xyz or xyza does not affect the visualisation of all 4 axis defined in the config (= all 4 are displayed)


3) Question: is the "Max Velocity" concerned for the linear movement only ? Otherwise one additional for the angular velocity would be nice

4) the steps of +/- selection for the manual axis movement should contain also the "degs steps" for the A-axis. These are defined at the beginning of the configuration under the "Increments" section. I would make two separate "Increments" resp. +/- selection sections for length and angle




5) the Jog Speed deg/min does not seem to correspond the real value when moving (maybe only a problem with the pulses/rev definition)

6) all the regulation slides (jog speed, max velocity, override) are quite rough in the settings (with mouse pointer drag). A tipping value would be much better or at least an additional fine slide dragging with mouse roll (keeping the mouse pointer for a coarse setting)


That's it, what you think ?

Have a great Friday

You won't have to do the manual fix more then once - it only happens when changing a config from xyz to xyza.
It's fixed in the next uodate.

1) I've actually never heard of anyone wanting rad for the A Axis.
2) Display Geometry affects how the plotter displays the rotational axes; It won't do anything on a XYZ config.
linuxcnc.org/docs/2.7/html/config/ini-co...tml#_display_section

3)Max velocity sets the absolute maximum velocity of any axis - in therory ;
github.com/LinuxCNC/linuxcnc/issues/523

4) AXIS doesn't support separate rates comboboxes for linear/angular axes. You must combine them in the one box.

5) Are you talking about in AXIS or in Pncconf?

6) That's an AXIS limitation and/or a computer userspace lag problem. I don't delve into AXIS, but will look into solutios for Qtvcp's version

i have problem with Pncconf for mesa card 5i25 as pictures.
Pls help to overcome
