The 7I96S isolated outputs can be sinking or sourcing on a per output basis
The 7I96S isolated inputs can be all sinking or all sourcing (depending on how the
input common is connected)

7I84 outputs are sourcing and 7I84 inputs are sinking

The 7I96S can have up to 4 MPGs on its isolated inputs

Below is a sample chart of common Mesa cards, reasonably accurate as of the thread posting date.  Double check the values in the chart and use it to narrow down your selection(s).

 

 
 

I am a complete beginner and still in the process of deciding which board(s) to buy so this thread has been amazing. Thanks!

Small thing that I may or may not have caught, though. In the list the 7i96s shows a 0 at MPG. But while not having designated MPG pins per say, it can supposedly convert some other pins to run an MPG. Maybe one of the axis banks or something like that?
So, say, for a 4 axis machine with one stepper/servo on each axis (like what I am aiming for) the 7i96s still has one axis not being used and hence, if I am correct, can still work with an MPG.
Maybe worth making a note of as I would think a lot of people buying that board will only use 3-4 axis:)

If you used a 7I96S, you may need to add a daughtercard to get enough I/O
The 7I95T probably has enough I/O but lacks the 0-10V. The lack of 0-10V
may not matter if the spindle drive can use an alternate speed control method
(also 0-10V can be added to the 7I95T with a  SPINX1 adapter)

I am def ok with a daughterboard, but not sure which one to get? Anything off of the top of your mind? 7i84? 
I still haven't gotten a grasp on the sourcing/sinking and I don't think the 7i84 is agnostic in this sense as the 7i96s seems to be. Any way can you take a stab at what would work for me given the list above? I can easily buy new prox switches if need be, if that somehow helps swing it to one side or the other. I do have a used Metrol tool setter. Should I try to find a manual to see if there's any mentioning of sourcing/sinking? That is the most expensive peripheral I have, I think. And then I think I will start with a cheap 3D probe from China, but not sure what signal that needs, either. 

Oh, which leads to another question (sorry), but can I mix sinking and sourcing on the 7i96s or do you pick one or the other for the whole board? 

Hello everyone:

for the industrial touchscreen monitor when I enable SETTINGS -> USE VIRTUAL KEYBOARD , I got an error like this:

I just start a sim config

Thanks

Thanks Lcvette, I actually had already hacked my way around by searching and replacing the original .ui with the modified .ui and now I have a working (albiet not the prettiest) vertical Probe Basic. I will try the correct way to do it on a dev machine.

Thankyou, I have expanded out to 3x drives and all working well.

I am accessing my LCNC via RDP and noticed that response to the gui slowed considerably while LCNC is running.

My fix was to set coalesce on the interfaces, here is my /etc/networks/interfaces where enp2s0 is my user interface / general network access and the eno1 is my ethercat interface.

cnc@cnc02:/etc/network$ cat interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

auto enp2s0
iface enp2s0 inet static
        address 10.1.1.14
        hardware-irq-coalesce-rx-usecs 0

auto eno1
iface eno1 inet manual
    hardware-irq-coalesce-rx-usecs 0


 

So if I were to use a different brand of analog servo, what value should the Drive scale be set to?

Any luck finding a solution?

Hi, I have been looking at this and cannot replicate the issue. Please share your config file as all the combinations I have tried work ok for me.

Hi,

I've got M6 remap running well from pure Python remap on my Biesse Rover 322 and now want to extend the script with manual tool changes for some tools.

Is it possible to call a default manual tool change from the python script, or do I need to build my own within the script? I foresee some possible hassles with cuebusting if building my own, that could be avoided if using the default one.

If building my own, would the attached script be a good place to start stealing from?

I'm retrofitting a Sodick 450MC, got most of the stuff working and running up to automatic tool change part, the tool changing arm is driven by the stepper motor,
​the stepper will rotate some fix turns to change tool
So how can I config stepggen for the stepper ? btw I'm using mesa 7i95 board

Sorry to be the barer of bad news, but there are several topics here discussing the DMM servos inability to run in analog mode due to very high latency of encoder feedback.
Use them in Position mode (step/dir) as this seems to work a bit better from what i read, although i never used them and after seeing how they handled the issue, i never will.

Looking at the above post, I don't recall installing headers separately. Maybe that is it.

These are also needed to install anything with dkms like the Realtek r8168-dkms network driver.

Not to mention network manager seems to be missing on the pi image, or at least there is no straightforward way of launching the gui for it from any menu I’ve looked in. So currently no internet connection on the pi, will work on that tomorrow.

Please read the notes on the download page to set up your wifi. Network manager adds latency.
Please follow the instructions  in man hm2_eth to set an IP address for your connection to your mesa card

How was this resolved? I'm using MesaCT v 2.1.4 to configure 7i97T+7i76 and I also have a spindle tab with all option grayed out. I'm planning to use the TB4 spindle output output on 7i76.
