Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

look, the square encoder gives us the direction and frequency, you can also calculate the angle and so on, depending on the accuracy of the encoder, the Z channel allows you to refer to the position of something, for the MPG Z is not needed, for stepper motor feedback, I would choose a diver with encoder support, and now I want feedback of the spindle speed, in theory it can be implemented using A encoder channel, or the Z channel theoretically could also give such functionality, I don’t need to cut threads, just feedback of revolutions per minute

The 7I96/7I96S are step/dir controllers. The 7I96S has a one channel 0 to 10V
output for spindle control. I think tommylight suggested the 7I96S as it gives
you some step/dir outputs for added drives.

For an analog  servo system you need multi channel analog outputs and
multiple encoder inputs. You can add these to the 7I96S either by adding a 7I77
or a 7I85 and 7I83.

A 7I84 just adds more digital I/O say if you have a tool changer.

Sourcing means for example an output device that supplies +24V to a load with a negative common
 

Sinking means for example an output device that grounds its outputs to drive loads with a +24V common

so now I'm a little more confused.  I just read about the 7i77, which seems like doing the 7i96s plus 7i77 would get me where I want to be, but then I looked at the much cheaper 7i83, which appears to do the same thing?  

and you said pair the 7i96 with a 7i77 or 7i85 and 7i83, so why would I need the 85 and 83 together?  So is a 7i77 essentially like a 7i85 and 7i83 put together on one board?

I'm sorry for my complete ignorance, but so many of these cards seem to do the same thing, especially to someone like me who has no clue about things...

RPi 4B - LC2.8.4 vs LC2.9.2 - Queue MDI Commands, Run From Here was created by electrosteam

RPi 4B - LC2.8.4 vs LC2.9.2 - Queue MDI Commands, Run From Here

Category: Basic Configuration

My RPi mill is currently LC2.9.2, and very successful.
But I cannot queue MDI commands, and Run From Here starts back at the beginning.

I have assembled a test setup to check operation of my old 7i96 Mesa, and installed LC2.8.4.
The LC2.8.4 allows queuing MDI (checked to 8 in stack), and Run From Here does just what it says.

I am inclined to change the mill back to LC2.8.4 to regain the "features".
What are the pro/con ?
Will LC2.9.3 include the "features" ?

The old Mesa card, originally removed because of perceived ethernet problems, is refusing to connect.
I will see if I can get the card checked locally (Sydney).

gmoccapy z height after hitting start

Category: General LinuxCNC Questions

For some reason the tool is always way above the work. Every axis was zero, it homed Z, came down and its very high up. If i rezero Z again, it works as it should. Ideas?

You can change debug level to 5 i think it will give more details if you run from terminal. ;)

Thanks for help!!...I will give that method a try.....also thought that I may be able to do both cutters off same gcode..only reverse one...the finish cutter may be able to live in the larger cutting point of the rough...working right behind trail edge of rough cut..

Thanks again!!

Get the appimage version, no installation required.
After download right click on it, go to permissions tab, check the "executable", close, double click on the file to run.

IMA quadroform C80/480

Category: Milling Machines

 
  • I have access to a CNC machine for wood processing IMA quadroform C80/480, which is from 1997. The machine works from its control panel and executes commands. The software installed on it runs on Windows 98.My question is:
    • Is it possible to run this machine using LinuxCNC? Is there any point in converting such an old machine to operate with LinuxCNC? Has anyone modified such a machine or a similar one for this purpose?
  • And a second question, kind of related:
    • What would be the best free CAD/CAM software for generating G-code for this machine, given its current system, which reads G-code files in the *.src format?

So I read about the 7i96s and 7i84 last night and some this morning, and I have another question.

It appears to me that the 7i96s has only one set of analog output, which would go to a spindle, and the x,y,z axis pins output step/dir. Are you saying the x,y,z pins can be changed to output +-10v instead? or is that what I need the 7i84 for?
If so, which 7i84 should I get, sourcing or sinking? I have no idea what either of them mean.

Wow, your conversion looks like a lot of work. Very impressive (and a very clean control cabinet!).
Yes, the schematics came with our machine, I am more than willing to share the pdf of the schematics with you.
No, currently I was not able to fix the issue, as I am currently out of country. We have the same e-stop chain and I also thought, maybe it was just the overtemperatur switch, but the manual for the original control also listed the possibility of a malfunction of 3F1 (Druckschaltgeraet), but i am currently not quite sure, how that would keep the machine off...

I guess somewhere I read about installing the RT kernel first to be installed and then switching to that kernel. Thats here I think:7.1. Installing on Debian Bookworm (with Preempt-RT kernel)I think To create a image similiar to the one you pointed This process shall be followed.  That shall ensure that I can have an iso image which I can take to another PC and install directly on my actual machine running LCNC.

But at the moment I am following 2nd build type to create a debian package for me to install on the system I am running:
6.4.2 Building Debian Packages

After configuring and starting build, I get below error.

Ok, still, if you want to run machines with the image you created, you will need the RT-Preempt kernel.
Or if you want to run machines from parallel port use the RTAI kernel.
In any case, after installing said kernel, do boot into it and remove the generic kernel.
