- The controlpanel for my DIY CNC epoxy granite mill. It will be running LinuxCNC and use EtherCAT. The machine is an all-servo, 1,7ton of epoxy granite with a 10hp spindle. I've built almost everything from scratch over the last couple of years. Almost everything is wired up and ready to make first chip! After first chip i'll be building an enclosure, stay tuned!
Nice, would love the time to present like this 😊
Thanks :)
Id love to see a detailed video on your machine!!
I'll see what i can do! Was thinking about making a couple of longer videos covering the different parts of the machine. So stay tuned ;-)
@TwinOaksGarage Right on Bro!!! I'm wanting to build one myself and love all the knowledge and advice I can get... Thank you
@@trevordeemie674 You might want to have a look at the buildlog i've made for this project: www.cnczone.com/forums/vertical-mill-lathe-project-log/417268-forum.html
...there is a LOT of information and input from other users on the forum aswell....
@TwinOaksGarage this looks like Stef van Itterzon design... By chance did you download his files and build it?? Looks identical
@@trevordeemie674 No, my machine is quite a bit larger than his. I've designed this from scratch myself, but a lot of inspiration came from his (and others) builds.
Incredible build! Whats thr latency like on the pc? Or does it even matter if its not generating steps?
Thanks! Latency is not important when the computer isn't used for stepgeneration:-)
hey badhabit, didn't quite get that, that's a rasp pi with linuxCNC as controller?
Hi! Mjea, almost :-) Its an "Odroid H2" SBC that runs LinuxCNC... the current model is the H3, i think, and there is also an H3+... neat little x86 boards with dual LAN, perfect for EtherCAT setups...
@@TwinOaksGarage ah so x86, I was thinking of putting linuxCNC on my old laptop just to test the drives and sensors. Do you still need a mesa card for your setup?
@@jonjon3829 Hi! I'm running EtherCAT between all devices. So from the extra LAN port on the Odroid H2 i'm running a cable to a series of Beckhoff modules(the ones mounted in the back of the controlpanel). These provide input from buttons, outputs to lights and so on. From that block of IO modules a ethernet cable are running to a similar block of Beckhoff modules in the electronical cabinet on the side of the machine. Again these are IO modules for relays, contactors, sensors and so on. After that the cable continues to each servo-drive. It is just a daisy-chained setup. The cables are plain ethernet cables, but instead of a regular ethernet protocol it runs EtherCAT which is purpose-built for this sort of stuff...
When running everything on EtherCAT modules i don't have the need for MESA cards. There is nothing wrong with MESA cards and it would likely be cheaper than doing a "pure EtherCAT"-build like this...i just thought it could be interesting to try to use EtherCAT for everything 🙂
@@TwinOaksGarage it's great that you can skip the mesa card, they are always out of stock. Similar with beckhoff modules. I think you waited like what 6 months to get them from the order date? I'm going with delta for the drives and also because they make their own ethercat modules. They mentioned lead times of up to 4 weeks but not longer. Hope that's true...
ethercat may be more expensive but you can't ignore how much easier it is to wire things up.
