ok great, will have a look. need to see if there is a way to have that set from system preferences maybe. hmmm

the probe basic atc sim has the macros setup in the config files to be used as a template, have a look at toolchange.ngc and M10 thru M26.ngc in the subroutines folder.

great! glad you got it working. always refer to the sim configs if you get stuck, everything has been done there to test functionality.!

Hi all,

Today was a lucky day. We managed to fix acceleration spikes at the 4-clothoid-spline junctions.
The problem was solved by using a new gauss legendre and minor function updates to the clothoid3d lib.
The iteration for gaussian legendre is now set for a 16 for loop.
We can expand to 32 or 64 loops to even increase accuracy.

Now i changed the back color off halscope to plot a white background as this is nicer for websites and documents
to show pictures.

Below are some halscope results, where motion is passing trough 3d-clothoids. The acceleration spikes on
joint 0 & 1 are gone. This tells us the interpolation off the clothoid is now absolute. And without any numerical errors.
So now the clothoid interpolates just as a line or arc.

This was really a bad situation. Wich is now solved.

 
 
 

Git is updated.

I did not realize that was there. I will look into it. Thank you.

Maybe I didn't mention that clearly enough:
I do not have any hardware, yet. I try to figure out which machine to get without having to run a WindowsPC. The mentioned type of machine happens to be a supplier in my country, which perhaps makes communication and delivery etc. a bit easier.
So It might be an option to buy the mechanical parts incl. the stepper motors without the controller.
Maybe I lack some basic knowledge. As I understand it, "information chain" is like this:
PC -> controller card (in this case the recom. mesa cards) -> motor drivers (as in power electronic) -> physical stepper motors).
If that is right, from what I read here: www.cnc-step.com/wp-content/uploads/2021...ero-4-35A_EN_2.1.pdf
(page 26 ff) it seems controller and power circuit seems to be a all-in-one custom setup.

Yeh, I guess so.

Should we delete the other topic, that i already moved?

Thanks for that.

Will test it this weekend.

Before this gets out of hands, open the box, take some pictures, we can figure out a lot from just pictures.
Reason being, in most cases you yank the control card and leave the drive/motors as is, use a parallel port or a Mesa board as control and make chips.
You can always start with a parallel port (or two) and later get a Mesa 7i92T that replaces both those ports, with much, much higher step rates/speed.

First you need the exact info on how the H bridges are controlled, there are several types/modes, then based on that see what the Mesa 7i95T should output.

Moved to "PlasmaC" section.
Thank you.

I want to understand how can i change the acceleration in linux cnc in realtime,  I also want to do some work on linux cnc professionally and  i am ready to pay , can anyone suggest me professional working on linux cnc?

I Initially thought it was due to an incorrect .ini file version but I eliminated that as the fault
 
Is this error message generated by QTplasmac?
It is not documented anywhere I could see. In any case it should not continue to appear.
