i have disabled all the options in the above picture . the latency test is still early, but it looks much much better

OOPs   i read a snippet from somewhere that said it would be good to start on a single core and the add the cores if i need them?     

i disabled the C1E, but not the C1,   i did not see C1 as De-selectable,   I will try again 

i can change it back correct?

OK C state support is set to C1.

and multi core is RE-enabled

thanks very much for your help PCW.

i am re running latency test again,   i did not take a pick from a few minutes ago,  but i think the servo thread was under 10000, and the base thread was about 26000

 

yes, you want multicore processing enabled

You should also disable Cstates > C1
 

After a bit of luck i have managed to access a menu that has the hyper threading setting.   In the pic  i have disabled the top 2 options.    How about the rest of the settings in this menu? 

  DO i need multi core processing??

Are these changes permanent or do I have to resett them every time i power cycle?

also i am double spacing these posts when i type, but when i submit the post ;   they get all squashed together.Is there a way to keep my double spacing so the post is easier to read? 

Thanks rodw,

I've added the following to my .ini file:

[LASER]
laser-offset-x = -3.2017
laser-offset-y = -0.2124

I've tried several ways that I could think of to reference these values in the gvcp-panel.ui, as CALL parameters to the EMC_Action_MDI widget without success.  I've also tried to just reference them in the auto-xy-zero.ngc file called by the EMC_Action_MDI widget without success.

A review of the online documentation has not been helpful either.

What is the correct method to pass them to the ngc file for execution?

Kind regards,

Hi, after a couple of months I'm back on my Brother TC201 retrofit, Will post pictures soon. As a newbie with probe basic (and LCNC) I did my best to configure it but without luck, I guess I'm missing a big chunk of knowledge somewhere but cant figure out. here is my config, actually the ATC tab look like in the screenshot. Please point me somewhere

Another thing I noticed is that when looking at the circuit diagram the +24 volt input is not connected to anything, the same on the PCB this pin is not connected either, only -24 volts is connected to the current limiting resistors at the inputs of the optocouplers of the inputs.

The CAT3000 definitely doesn't work with Linuxcnc with the latest version. If I connect it to TwinCAT, there's no problem. I can go to OP state, the inputs and outputs work, the encoder too, but with LNC, nothing works; it doesn't go to OP state. Something very strange is that many Enable pins are generated, 8 in total for each Enable, as seen in the photo. I don't know if the problem could be the ethercat-conf file.

You could run a unipolar analog drive (0 to +10V) with direction control by using the
abs component on the output of the position PID loop in LinuxCNC. The abs component
has a sign output that could be used for direction control.
 

Dear members,

my milling machine has four 12 VDC Tacho-motors for the axes  The direction change is done by a switch and by relais. It is not a CNC control, it is a distance-control managed by a Heidenhain TNC113 for each axis seperately only in sequence - not in parallel. So it is easy to change the motor running direction by a switch or by a relais. The motor amplifier accepts as external signals only 0 to 10 VDC and an "Enable".
 

The question is how to handle the MESA output which ranges from -10VDC to  + 10 VDC to have the motors run-direction changed.

The only other option of aan amplifier which I found is from RS Components, which has a direction switch. But it works also only with a signal voltage of 0 to 10 VDC.
 
I there any helpfull idea how to realise the controls without relais?

Thanks a lot and best regards

Hartwig
