CAN works well, I'm glad they didn't try to roll their own version. And they have done a lot on the RT side to get the peformance as good as they have.

Nothing wrong with that🤷🏻‍♂

The BACnet and Modbus IP implementations are built similarly; they're thin ethernet wrappers around the original protocols, which while easy to implement and understand for people who spent their whole lives working with BACnet or Modbus, does result in some pretty clunky and redundant protocols with duplicated or unnecessary address fields, checksumming, bad port handling and inconsistent implementation of typical ethernet or higher conventions. If you wanted a well-designed clean implementation, you could strip out 80% of what industrial protocols like this do because ethernet/IP handles most of that functionality already. They leave it in though, because it's what they're used to.

@@siberx4 Yeah I did some work on it for a communication library and like 90% of the packet was communication overhead already handled by TCP/IP. The remaining 10% was "Send me variable XYZ". The cool thing about that is that, with an EtherCAT gateway, I could use the same 2020s Python library to communicate with a PLC from the 80s that was designed for a ring network.

Yay excited to see some more spotlight on EtherCat! I got to work with it for a fun robotics project in my lab, driving some high torque and high precision harmonic drive actuators.

“HevORT” , “RatRig” , and “VZBot” are some other good printer designs along this line of thought to look into as well. I could dig for links, but i have tried to subscribe to like *all of the channels making that content*, so look around and ask if you need help! (Most of these Printers have huge Discord/Reddit Presence too) (Edit: Typo) (Edit 2: Added VZBot)

Oh yes please

More EtherCAT Stuff *AND* it’s *Open Source*?!? Sounds amazing! I’ll definitely need to look into your work.

Is people like you we appreciate

Yeah, too bad he didn't convert all axis when he did it. I think he left the Z-axis as is, if memory serves me right.

Yeah, it's a pity that it isn't used more in the Hobbyist-space. Devices which implement EtherCAT are usually made for industrial use cases, that's at least what Beckhoff targets. That makes them way too expensive for hobby side projects.

@@thevayudev The reason you're seeing them here is because these companies are repurposing copycat precision parts that were mass produced into cheaper packages. I suspect in the next couple of years you're going to see people design home based multipurpose CNC tables that can drop any any tools you want. This isn't the first video I've seen like this, these parts are becoming more obtainable and you could connect them to simple router, plasma cutters, or 3D printer heads and do whatever you want with them. People around me are industrious so there are a few small businesses that are already putting them to work in my neighborhood, which is a very stretch from the traditional machine shops they were in.

@@snarkylive Okay, that does make a lot more sense, that's why none of these are original parts from Beckhoff Automation, those aren't really produced in that high volumes. It does sound like a bright(er) future for the low-budget space if other manufactures can mass produce these components while still being able to communicate with TwinCAT & other EtherCAT stuff. Still waiting for price cuts in the XPlanar/XTS space because those things look like a lot fun to play around with. I mean, couldn't you replace the rails of a CNC machine with XTS rails?

@@thevayudev XPlanar and XTS is definitely a newish thing on the market. Even their competitors (B&R, Bosch Rexroth, and many others) just launched these kinds of products in the last 4-5 years. I doubt we'll see price decrease until the next 5-10 years, especially with current chip issues. As for XTS replacing CNC machine rails? Well, I think it can be done, but your material weight will be quite limited, especially if you have to stack another XTS on top of the other for X-Y plane.

Yep I second that, I find everything you do videos on so interesting plus Marko's sense of humour is the best! 😅👏

@@TheZombieSaints Indeed!

Yeah, we're becoming spoiled brats.🤣🤣

currently at 2000mm/s, not the speedboat though.

Disallow? Jeez, why, as if there are many printers with servo drives out there.

@@VEC7ORlt I think its to encourage stepper driver development and prevent things like dropping thousands of dollars on industrial drives...

@@pmcquay1 This is stupid, should be the other way around - encourage development of servo drives, as steppers are boring and mundane and we need more and readily available servos, besides if you are participating in the speedboat challenge you already spent those thousands, coz your prusa or ender can do shit, its the vorons and the like.

@@VEC7ORlt It would be buy your way to victory with servos, which of course every industrial enterprise does. But for a hobbyist the cost is usually a serious barrier.

What model of controller/motor did you get? And do you use linuxcnc as well, or something like grbl? I'm currently running open loop steppers with grbl, very basic setup but affordable at 200€ for all electronics. However, I'd like to upgrade that system to something more reliable.

MirageC and Vez3D have been doing some really good quantitative looks into all this, definitely worth a look if you want some answers to those kinds of questions. But yeah, *for the most part* (not including accelerations, movements etc) the main limit now is how fast you can heat up the filament and push it out. Volcano/Supervolcano Hotends, novel Heatbreaks/Nozzles/Coatings for Things (DLC, PCD Nozzles, etc) are helping, but next generation stuff will be even more interesting, the Goliath Hotend, and to a certain degree more Open Source Pellet Extruders (although iirc those inherently have less precision?!

Most OEMs like that are likely wanting you to go through a VAR. Though that also means higher costs which in turn isn't hobbyist friendly.

Well, the 10-20 bucks per IC/MCU usually doesn't break the bank of most projects so to speak. But it's one of the downsides of ethercat. For hobby use the whole Ethercat eco system including the usual go-to (twinCat) can be rather overwhelming if you don't have experience with PLCs. Also you better try to stay on the full open source side, especially with the master and if you can any further I/O, because getting actual beckhoff stuff will probably cost you an arm and a leg, unless you are a major industrial partner with >>50% discount. You do get a proper RT field bus (thanks to the DC architecture) with it though, so in applications where that matters it's a great system. I also liked what they showed this year with their modular robotics concept that uses EtherCAT, though I have yet to see the prices. But knowing them it will be pretty much impossible to use them in any price concious project, even in a low volume industrial setting.

@@ignispurgatorius5297 There's the Trinamic TMC8462A-BA which is a BGA part It seems to be around only £20 or so it would be interesting if this could be integrated into the Moteus (especially now that ODrive has gone closed source)

Probably EnDat ,it looks like th once yaskawa servos is using, I have been angling to get the data sheet of those encoders with no success, the pinout is not found anywhere.
