Can anyone show an example of a hal and ini file on 3 axis step/dir (XYZ) without feedback, 1 pwm (spindle), 5 inputs (home - 3, probe, e-stop), 1 output (mist). I would like to try to connect the simplest CNC3018. If you tell me or direct me where to look at a similar example, I will be very grateful

Hello!

I posted before relatively recently about this machine I received. it's giving me way more trouble to configure than I would like. The amount of confusion the config itself gives me is painful. So I need some advice. I was advised earlier that the config I originally used (as was a startup with a machine) was off. so I loaded up the earliest config which did have the correct orientation and yet refused to let the machine move by itself in manual control as the previous config did allow. Seems like the spindle is controlled manually via VFD and I have no idea how to link it to the operating software. I have no knowledge about the stepper motors and the speeds and all that jazz and me looking into Google for information leaves way more questions than it answers. Is there a guide I can use that helps with the software side of it ? I would like to at least make some progress cutting things :c.

So.. config is no help tbh. The work area is not set and I didn't see a prompt to set it in the config wizard. so the result is a tiny square in the corner. The machine also does seem to home with no problem but the spindle does not move in any axis and I cannot move it in manual mode. The VFD when powered up does spin the spindle at a set speed. (no idea where that control is).

So I need help or a guide or something before I end up giving up on this thing entirely. It's clear it's previously used Retrofitted the machine but I received no documentation with it so I'm a newbie with a nonstandard machine.

I will link my previous post as it contains pictures of my machine. 
I can always try to splash out and ditch Linux as a software entirely and use Denford's software or something that isn't infinitely confusing.

THANK YOU in advance for any tips and tricks!

Put in hal file setp cia402.1.velo-scale XXXXX. XXXfor velocity mode or setp cia402.1.pos-scale XXXXX. XXX for position mode the servo.

someone have never try it ... some special config on to ethercat config file? .... because never find port number only mac adress and ip adress on that file .... so not sure can work.

regards

thanks but where is this entered? in the encoder but under which category? Homing

It's simple: divide the encoder resolution by the screw pitch.

I just got a GS20 drive yesterday as a replacement for my mill but first I have to learn how to configure it for another project.

Hello, I use an AC servo with an EC interface. With a normal servo you set the steps on the encoder and then enter the steps in the controller.

My question is, is this also done with the Ethercat servo? I don't have any experience with servos like this. Or is it done in the Lcnc settings?

If this is the wrong forum, please move it, thanks

Yes that seems to work.
Note: Running './installer' ends with an error when trying to open a config in the end. But opening a new terminal then running 'source scripts/rip-environment' fixes it.

Okay, I'll do what I can to try to solve the problem until I run into a new one.
thanks.

Thank you so much.

I posted new result ( but I did not apply these options )
I will test later.
I should learn these options and tips.

Thank you.

I set the package power limit in BIOS to 0 for both sustained and burst mode,
But PC worked incredibly slow ..

Anyway, thank you so much. I posted new result, very improved.

Thank you for your advice, everyone.

I got this result so far. (90 μsec jitter) really improved. 

My question is " Is 90 μsec jitter is good enough to run LinuxCNC with MESA(Ethernet FPGA Stepper) ?

 

anyone looking to use the new thing with RPi5, keep in mind, you need to use the new firmware also. Right now Ive added a precompiled firmware for octopus446 and more will be added later but you can compile your own in the meantime
