Techno Isel Davinci

[Anonymous]

I'm trying to get Fusion 360 to work with a Techno Isel Davinci CNC Router that we have in our classroom.  I've tried using the rs274.cps processor to output the .nc file that I then change to a .ncd extension.  However, everytime I attempt to run the machine, it starts, moves a few inches and then gives a limit switch error (it isn't near any limit switches). 

I'm not sure the problem is with the post processor, but there is a stock .ncd file that is preloaded in the Techno GCODE Interface that will run fine.

Any ideas/direction?

Thank you!

Here is an Isel post made for one of out German customers.

I'll try it and get back to you asap.

Thank you

Works fine on the first test - I really appreciate it.

We are new to CNC - We also have an Isel Davinci and we are struggling to get through the post process. The file it seems to output is a .ncp, we don't know what to do from there. We do have the driver downloaded from Isel automation's website, but it won't read a .ncp file at all. It's looking for .ncd - we don't know how to create that type of file and then what to do from there. Any help you could provide would be very much appreciated.

Also what does the .cps file do that you posted here?

As I'm working through the same issue, I think that the .cps link is a Post Processor. You will need to load this Post Processor to your A360 Cloud Account after enabling it in your Preferences in Fusion 360. I found, and followed this https://inventables.desk.com/customer/en/portal/articles/2332499-installing-a-fusion-360-post-proces.... Although it states that is for MAC, I followed the instructions and successfully added the .cps Post Processor option to my A360 storage. To access it, when your CAM is complete, click the Post Process Tab, under the Configuration Folder, click Setup, then choose Use Cloud Posts. Your Post Process will now use the isel.cps Processor that you uploaded and produce a .nc file. This is where I'm at. Now off to barn chores and hope to run the cut later.

Full dislosure, I'm very new to Fusion 360. I'm a self taught 2d CNC cutter guy. We use a large 2 axis cutter in our canvas manufacturing business. I'm also pushing 60 years old. I took a 4 day crash course in AutoCadd LT and the format software for my Gerber cutter 20 years ago. I'm a wiz at what works in 2d CADD using AutoCADD LT 95 and AutoCADD LT97. I recently bought a Tecno Davinci mill from the local Vocational School and have been fooling with 2d CADD to machining using Meshcam. I tried Fusion 360 about a year ago when I purchased the Davinci,  but was too ingrained in the CADD that I knew. Old dog and new tricks scenario. 2 weeks ago, this tenacious old dog decided to give it another go. I'm still fumbling with the CADD portion, but the CAM is great. google and youtube tutorials have been my guide. My best epiphanies come when I'm trying to sleep. The .cps question was such an epiphany. Hopefully it works as I suspect. This morning, after enabling the A360 access, I was able to generate a Post Process .nc file. So far, so good. We'll see later what the Davinci makes of it.

As a follow up, the Techno Isel Davinci requires a post processor that generates an .ncd file. I have followed other's suggestions of renaming the .nc file to change the extension to .ncd. The Davinci seems to recognize that there is an .ncd file to open, it shows the formatting to a .cfg file, but in the preview pane, there is nothing present beyond the origin axes indicator. Then the program locks up.

No joy yet. It's looking like Meshcam, which has a specific Davinci post processor, is the only thing that works for me. I really like the CAM in Fusion 360, but without a workaround to the Techno Isel Davinci issue (which seems to be a common problem discussed here and on the CNC Zone site), the backwards step to Meshcam may be the only solution. Fusion developers, are you listening?

Do you have any sample programs that came with the machine? That way it could give us a better idea of what is needed.

 Matthew,

Earlier today I found this file 7437_rs274.cps-RS-274D. This post generates a .ncd file that I can open and preview in the Techno Isel Davinci software. The problem now is that the isometric view and tool path are several inches from my chosen origin. In trying to execute the cut, the x axis gantry moves to the extreme right and jams the machine.

I've uploaded a few .ncd files. After attempting to send these, I got an error message that .ncd wasn't an acceptable file extension. I had to rename them as .nc files. Not sure if they will behave correctly.

2boxes is a file included in the Techno Isel Davinci software. It executes correctly.

jeepgrill is a drawing I did in AutoCADD LT 97, exported as a .dxf into Meshcam, extruded, tool pathed and successfully executed several months ago.

pocket455 is another Meshcam file that I created and executed several months ago.

Thank you for your insights

Another follow up Matthew,

I was being bothered last night by the large offset in the Preview pane of the Techno Isel Davinci mill. I do my best thinking while trying to get to sleep. It seemed to me that the coordinates I was picking with the cursor, and doing some simple math, seemed like an appropriate conversion relationship of mm to inches. With that in mind, and knowing that the Davinci's default is mm, which I have changed to inches, and that the model I'm using is in mm; I have changed the model to inches in Fusion 360, and tried the 7437_rs274.cps-RS-274D post again. The Davinci preview window now seems to display correctly, within the bounds of the work area. The measurements are also matching the model. Could the solution be this simple? Please, before you simply answer yes, give a look over my submissions, and give it some technical educated thought.

dpizz (or anyone),

Is this working now?  

And where did you find the file 7437_rs274.cps-RS-274D, or is it the same as the 7437_rs274 ?

I'm just getting into cnc with a DaVinci, and at age 70 it's a bit challenging.  Worked my way thru Fusion CAD & CAM, ready to try cutting, but totally confused about this post processor business.  Hope your solution works!

Richard,

Yes, all is working now. Make sure your units of measure in your CAM match what your Davinci is set to. Ultimately, that was my only problem. I've attached the post processor. I found it on one of the many discussions on the Fusion CAM Forums. It took quite a bit of searching and luck to find it. So much so, that I can't find it again, but I have it saved on my computer. I seem to think it is different from the one in the CAM Post drop down menu. You'll need to follow the instructions in one of my prior posts  to upload this to the A360 Cloud and run your Post Processor through there. As I followed so many different search leads to work this out, I frankly don't remember if the 7437-rs274.cps in the dropdown menu finally worked or not. As I recall, it yielded an .ncp file. There is no reason that the file name extension  can't be changed to .ncd. In thinking back, my Davinci may have recognized the changed extension, but I had not yet figured out the conflict with units of measure. By all means try that first as there is a lot less drama involved.

Another helpful bit of info I figured out, as I was moving files from my laptop to the computer that runs the Davinci, I had to go through several steps (literally) to try to run the simulation in the Davinci software window to know if it actually would recognize it and work. In the Davinci software files is a file named VNCD. This is the Davinci Viewer. I copied this file and put it on my laptop. I can now check my post processed work both in the Fusion 360 CAM Simulator and in the Davinci Viewer without leaving my recliner.

[rsnewmanRFVUW]

Thank you so much!  Can't wait to get to the shop and give it a try.

And thanks for the tip on the DaVinci viewer, but I'm doing my CAD/CAM on a macbook, so I don't think that will work for now.  Have an old Dell laptop in mothballs, maybe I'll try that.

Next big issue is to deal with the runout in the Kress spindle on my machine, it's a whopping .004" TIR.  I making banjos and will be cutting pearl inlays and inlay pockets with tiny end mills, need to get it down to less than .0004".  Should be able to cobble something together on the lathe using a die grinder or pencil grinder.  I'm much more comfortable with this sort of thing than the software stuff!

edit:  I just compared your file and the downloaded one from Autodesk and they appear to be identical  (opened them in text edit)  But now yours is forever preserved here in this thread.

[rsnewmanRFVUW]

 I just looked more closely and they are definitely NOT the same!!   My mistake!

Your 7437_rs274.cps ‏30 KB above outputs .ncd files, while the Autodesk site download outputs .nc files.  And there are many other differences as well...

Duplicate post, please delete

I can verify that this file works.  Do a search for .cps and you will find where to put the file.  In Windows 7 it is found here.

C:\Users\name_of_current_user\AppData\Local\Autodesk\webdeploy\production\84f1b51e7d7e35aa10511b736710ea444a791fd0\Applications\CAM360\Data\Posts

Put the file in this folder and it will show up.  I still need to sort out the units.  I usually work in inches not mm.  It was also recommended to me to change the property allowHelicalMove from Yes to No.

[Anonymous]

Do you know why allow helical should be disabled, and how to go about doing so?

Thanks,

[dillonpapa]

It is because the Davinci is only 2.5 D. It can not move x y and z at the
same time.

[wwisdomKXEX9]

Thats not true. I've done a lot of 3D cutting on my Davinci.
