M3 screws follow the socks.

On a serious note I'm going to delve into the abyss that is BSPI, and see if I can do something to read a SPI ADC. Hopefully something that one can get readily from Aliexpress. Though that kind of shenanigans with require at least 4 pins.

Rpi Images are up now.

Once again thanks to Andy for making it all happen.

Wow Pete, are you Soloman ?

Yes (this appllies to most step motor drives with opto-coupler inputs)

Yes.

Yes, you can make a little loop at the drive.
(if you are good with a wire-stripper you can do this with a single piece of wire)
 

Thank you for your times and your kindness PCW. Best regards.

What kernel and Ethernet hardware do you have?

uname -a

will give the kernel version

and lspci | grep -i eth

will usually find the Ethernet hardware

What is the Host PC?

Have you run a latency test?
 

Hello
Im new to this forum maybe someone can tell me theirs actually works after waiting weeks for my new 7i96s all it has given me is grief from ethernet driver errors to update errors. tried the newest release didnt work. tried older ones they are poopoo. Do the makers of this software test it doesnt seem like it. Is there any software that works with this board without being a genius at linux. I know im complaining a bit Ive spent days to no avail.Im bald from pulling my hair out.You would think Mesa would test it with linuxcnc.I know linuxcnc used to work now everything is horse menure.
     I was told it started with implementing ipv6. who cares change it back.no matter what i do i cant get any pulses.

OK, moving it back for now, let us know if and when we need to move it.
Thank you.

The only reason I put it there instead of here was for a broader audience. I figured maybe someone might know about sources for LeadShine products who might not read the EtherCAT forum. Here is fine, though! No big deal.

cheers,

LM331 Is cheap and easy to find, amazingly i can find it here, although i can not find M3 screws!

Moved to "EtherCAT" section.
Or, was there a reason why it was on "general LinuxCNC questions" ?

Estos son mis archivos con 4 ejes y funcionan bien. El 5to eje B debería ir a los ports 14 y 1 del DB25 1205.
Mi objetivo final sería con 6 ejes, siendo el sexto el C y debería ir a los ports 17 y 16 pero no se usar el PNcConf

Slds y gracias.

   

I want to add a couple of physical pots to control Jog and feed speeds.

I'm using a 7i96s, and I don't believe that particular card has analog input capability.

I'm sure there are many ways to accomplish this. On my mill I used Arduino Connector and it works well, so that's an option, however fair bit of carry on for just a couple of analog inputs.

Thinking out loud... I could read the pot values with a dime store 8 pin uC and do a voltage to frequency conversion, and then apply those variable frequency signals to two digital inputs on the 7i96s if there an easy way (in HAL) to then measure that frequency and apply the result to:

halui.axis.jog-speed

and

halui.feed-override.scale

Or, perhaps there are other better ways, any suggestions?

 

Hi,
I'm tweaking HAL files for my new Lathe. I have independent hardware jog buttons for the X & Z axis. Presently setting jog speed with: halui.axis.jog-speed

The jog buttons are working however I would like to set the halui.axis.jog-speed to different values for X & Z.

What would be the easiest way to do that?

Thanks.
