Koike Aronson Plasma Conversion - sanity check on Mesa board selection?

Category: Driver Boards

Hi all, 

Looking to help a friend do the same thing as this thread, but with a 7i97T for the servos and a 7i78 card for the stepper for Z and THCAD2 for Arc Voltage. 
I could use some help reviewing the hal and ini files to see if I'm on the right track.  I built a stepper machine before with a 7i96s and THCAD2, so have some experience with the setup using PNCCONF.  This is my first attempt at editing the ini and hal files directly.  I combined the basic 7i97 file, with the JT's configurator tool, and the plasma specific info from my 7i96s config.    My main question is how to correctly identify the board names in the files.  In the ini file it shows 7i97T as the board and 7i78 as the card, but I don't see how the 7i78 board gets translated to the hal file?  Ignore the scales, drive values, and pin assignments for most of the signals for now. 

Also, the servos are Cleveland Motion Controls p/n MTE3528-508BG, does anyone know how to determine the encoder scale on these?  May just have to measure it once the system is configured.

Best way to get a couple of analog values into HAL?

Category: Basic Configuration

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.

7i96S card arrived what setup is recomended

Category: Driver Boards

1.
Yes (this appllies to most step motor drives with opto-coupler inputs)
2.
Yes.
3.
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.

Mesa 7i96s Is linuxcnc poo poo now,Ive never had to troubleshoot this much.

Category: General LinuxCNC Questions

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?

Mesa 7i96s Is linuxcnc poo poo now,Ive never had to troubleshoot this much.

Category: General LinuxCNC Questions

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.

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,
Steve
