Thanks for the advice! I managed to install RTAI using it

My latency numbers improved, but not as much as I hoped for. I need to look into new motherboard.

Done, it works!!!!!!!

Now I have to manage to make it permanent somehow....Any clue?

Thanks again!!

Use what you are used to. I have nver used CL and just write a comoponent.
Here is one to select from rapid/slow jogging  when an extra button is pressed. Hal just got too convoluted
github.com/rodw-au/showstopper/blob/master/jogpendant.comp

I have a physical pot that is driving halui.axis.jog-speed.

Implementation in postgui.hal is as follows:

# Jog Speed
loadrt scale count=1
addf scale.0 servo-thread
setp scale.0.offset 0.0
setp scale.0.gain 0.12
net jog-pot-in scale.0.in <= arduino.ain.0
net jog-speed halui.axis.jog-speed <= scale.0.out

This works in the sense that I can change the jog speed and then the next jog will use that speed. however if while jogging I tweak the jog speed value with the pot, halui.axis.jog-speed changes however the actual speed does not change (until the next jog). Is there a way to make the jog speed follow the pot/halui.axis.jog-speed value while jogging?

Am I using RETAIN_G43 correctly?
 

At the moment I answer: NO

I readed definition of RETAIN_G43 again:
linuxcnc.org/docs/stable/html/config/ini...sub:ini:sec:rs274ngc

RETAIN_G43 = 0 (Default: 0)
When set, you can turn on G43 after loading the first tool, and then not worry about it through the PROGRAM. When you finally unload the last tool, G43 mode is CANCELED.

I think the RETAIN_G43 function is for *.ngc file read only. After the *.ngc program ends, it is deactivated.

Therefore, RETAIN_G43 cannot be tested in MDI or MANUAL code.

I need to get around to doing this sort of thing myself. I usually use Classic ladder when I do things like that but
Classic Ladder feels like overkill when doing 1 or 2 simple things.

Our government thought we needed a level playing field so tarrifs are typically 5%. But we have FTA's (Free trade agreements) with a lot of countries including USA, UK, China and India where the tarrifs are waived. Typically though these need a certificate of origin (COO) stating  its made in our partner country. Generally, these are issued by the government for a fee. Sometimes its just as easy to pay the tarrif instead of pay the fee which also saves time.

Oh and we still have a luxury car tax to protect our local car industry which shut down totally a few years ago.

Thanks for that.
The visual (block diagram) explanation works much better for me than the plain text explanation that I initially found.
excerpt from my postgui for anyone trying to figure this out in the future.... this works for me:
#  Analog Inputs - Jog Speed
loadrt scale count=1
addf scale.0 servo-thread
setp scale.0.offset 0.0
setp scale.0.gain 0.12
net jog-pot-in scale.0.in <= arduino.ain.0
net jog-speed halui.axis.jog-speed <= scale.0.out

Cant do this anymore bye all wrote:

Enough sarcasm.
The latest official ISO from the Linuxcnc home page is the way to go, it should “just work”.
Regarding your error, please relay the exact error you are getting, then we can move on.
 

I hope so.Took me months to build.... even Cornholio helped!

Linuxcnc is generally very good at reporting errors but you need to start it from the command prompt by typing linuxcnc to get the best reporting.
But typing "linuxcnc -l" where -l is "L for last", loads the last config you opened and I use it all the time as its a great shortcut

I am curious if they ( Government ) use the same rhetoric of they need to get away from imports, add tariffs for said imports while simultaneously
importing more products. At least that is how it seems here in the states.

Start with Axis always... move to another GUI once you have a good moving machine.

As an alternative view point, a stepper driven torch lifter with float switch and breakaway costs about $500. I just shipped a 72 kg QTplasmac controller package today, and we are replacing a motor driven torch lifter. He is also getting a 433 mhz wireless pendant. The client is really excited about the addidtional safety features he will get like breakaway, probe pausing motion if triggered by cutting and moving from DM542 drivers on 24 volts to Lam Technologies DS1076 drivers with 60 volt AC power, high quality Moon's motors with custom made 5:1 planetary gearboxes will lift this old slug into orbit!
Here is the lifter (200mm travel)
 

 

Strange, the parts I ordered on Sunday night from Element 14 arrived on Thursday with DHL ex UK. No wonder they don't hold stock here anymore.

Yes, its sad, We used to manufacture everything but sucumbed to China. But we are barely 10% of your size. Parts I used to manufacture I get made in China or India because I could not reliably source raw  material. One part I needed 50mm lengths of Silicone hose and when I asked if the manufacturer could cut to length they said no, my choice was 1 metre or six inches (they imported ex USA), Consequently the cost was about $17 a piece. But the cost in China when I went to a trade show there was $2.60 and nothing was a problem. In fact the same supplier is currently making a sample batch of 50 custom intercooler hoses with OEM fittings each end...

Thanks for the link! The mistake was that I did not save the session

No double posting, one thread per issue.
