Large horizontal mills with a quill will drive you crazy. The only way that I know of for correction is to use a laser scanner and develop a point cloud of X Y and Z. Starting with X0 Y0 Z0 to max travel in a grid. Then develop an error table based on measured and commanded. Remember that lights shining on the machine and room temp will cause drift. The weight of the tool will cause error. After you develop an error comp table, you can then correct the errors in the program in advance. Each axis has pitch yaw and roll, so a simple comp on Y to Z probably will not fix your problem. This is why we don't have horizontal Jig Bores.

Okay, a quick look through the code and a look at the ESI file for the EasyIO doesn't show anything *glaringly* wrong. On the other hand, I don't know if anyone has actually tried using this driver before, so 3 of 4 isn't too bad...

One quick question: did you set aout-1-enable?

What are the various aout-1-* pins set to?

Leadshine has an amazing ability to put out products with multiple names and not document them clearly (at least in English) for months after they start slipping into the channel. So I'm not sure exactly what a EM32DX-E4 is. I can find pictures, and a manual in Chinese (oss.leisai.com/uploadfiles/EM32DX-E4%20%...%8B%E5%86%8CV3_1.pdf) that I *think* says that it's a 16-port in, 16-port out digital I/O board with something somewhat odd about the first 8 digital inputs and 4 digital outputs

Ignoring the "something somewhat odd" part, it looks pretty straightforward, 16 ins packed together at 0x6000 and 16 outs at 0x7000. It'd be pretty straightforward to modify one of the other packed digital I/O board drivers to support this hardware.

Hey guys,

So most of my machine is running and I'm in the testing phases (Just have a sharpie in the spindle drawing stuff on carboard) before actually cutting anything and I've noticed what when I post my G code from Fusion360 and move the NC code into linuxcnc I get (Unknown G code used).

Now I figured there was un-supported G codes so I checked the list of un-supported G codes and editing them out of the NC and it made no change. But If I delete the entire Top few lines of the NC it then works fine (For simple line sketches haven't tried anything more complicated) 

Example below;
________________________________________________________________

(This gives the error)

(But this works fine)

________________________________________________________________

So my question is really, why is this happening? When I was running mach3 I could just drop my NC program in like this and it worked fine, and two is there a way to set up Fusion to post on NC code that WILL run on linuxCNC or will i have to edit each program like this to get it to run? 

Thanks guys  

Rick,

You'll find that there are many ways to accomplish the same thing in LCNC, but what I suggested was a combination of boards that would easily drive 9 separate axis motors, plus an analog 0-10v output for typical spindle control, plus a fair amount of inputs & outputs, plus has 5 high-speed encoder inputs since you mentioned 'closed loop.'

The 7i84 vs 7i84D - boards have the same I/O quantity, but one is for sourcing outputs and the other (D) is for sinking outputs.

The above recommendation is just that - a suggestion of an easy way to get 9 axes.  It was not a cost or space optimized solution, and I strongly discourage you from buying anything at this point.  You need to be in research mode right now.

If you want more specific recommendations, pics of the lathe, plus a detailed description of what additional 'stuff' you want to add would help us help you.  Pics of the existing control electronics (stepper drives, spindle drive, power supplies, etc.) and anything else (control panel) would help.

Make a list of all the inputs, outputs, axes, spindle, whatever.  Identify the voltages, amps, what components you have and will need in the future.

As for loading... are you talking about stock or part blank loading?  Does this hardware currently exist, or are you planning to fabricate some sort of automation mechanism?

W5500 seems to be ok so far, had it run through 2 goes of the example gcdoe, no issues.I'll just let it be for now.

Wasn't playing nicely when I had an intel NIC installed (this was just pruely for access to the local network). Even the UDP bridge was getting latency errors. Anyway removed the Intel NIC, all ok.

But yeah this is a hug improvement.

Many thanks ollie, and the clog2 issue appears to be fixed.

How do you like that keyboard and track ball?

Ok that work is pushed to master now.
I have not updated the docs yet, but stylesheets can change the options.
The menu items in the DRO or axis selection buttons can be made the same or any combination of those options.
Also now you can recover from pressing the zero button by selecting 'set to last' in the dro widget menu options.

let me know what you think.

Chrs

A while back i wanted to link this topic for someone who asked on the forum, i could not find it, so i pinned every topic regarding these projects i could find back then... seems i have missed quite a few so pinned this and all the rest.
Thank you.

read the comments on the downloads page. menu-config should do it for you.

In my case, it would be ethernet, I need the configuration area for the IP/Gateway address, that way, I can study the connection with ethernet cards.

IN the gmocappy source there is a screen handler written in Python. There is also a glade screen definition, You probably just need to modify the handler for the exit button or even better move it to the already password protected area. Sorry its been 7 or 8 years since I modified gmocappy

Could anyone help, I made the image for the pi4 following the image on the official page, but it doesn't have the area for ethernet configuration, how can I solve this problem?

The current 2.9.2 image  needs updating to 2.9.3 but we no longer install Ethercat repositories for the Raspberry pi.
I am not sure if the pi is supported in their repos for Debian 12 at all
Also I doubt that a linuxcnc-ethercat driver is built for the pi either
Right now your option is to build from source
I have raised an issue with Ethercat to explore a solution for this.

 

Spumco,

Hi...thanks for reply!...it will be wood lathe and I am wanting to do the equivalent of straighten,rough shape, then skew cut any geometry that may come...not easy by hand and involves much simultaneous movements as well as loading etc.
So I understand correctly...you list 3 boards with one having two options correct?

Thanks again,

Rick
