1. Faster processor speed (300Mhz vs 120MHz)
2. Higher current onboard drivers for NEMA23/34 motors
3. More GPIO
   etc, etc...

Why settle for less?

The Wifi 2 is such a popular board, the natural progression would be a Wifi 3. I see the direction going towards being a general CNC controller, but honestly there are much better existing controllers for that already that are well sorted (IE - Centroid Acorn) - I just feel like this is the best 3DP controller on the market...why is it being abandoned/going backwards? Of course, that's my opinion as a customer...with no offense given.

A word to the wise having built several Clearpath retrofits for CNC machines...Buy the Clearpath official power supply (or two if you need them) - to correctly power your motors. Cheesing out on the power supply with these motors will result in chasing your tail, pointing fingers in the wrong direction and a host of other problems that will cost you more than just buying the right kit to begin with. (I say this from 1st hand experience). They're not 'cheap' but they're what you need to do it right.

I just completed (mostly) my custom CR10S5 using a Duet Wifi 2. I really like the RepRap firmware and how easy it is to tweak things. I really don't miss recompiling Marlin...

Since I've been bitten by the proverbial bug...I now want to upgrade some of my other printers to Duet - but aside from the Duet 3 Mini - I didn't see another Duet 3 board with onboard wifi. What's up with that?

Why would I want to add another piece of hardware (RPi) to the board just to get wifi? Is there a wifi module in the works for the flagship board or am I stuck with using the older wifi 2 board? I was so close to pulling the trigger on 2 new Duet 3 boards yesterday and stopped because it doesn't have wifi - only via RPi & I suDon't know enough to be comfortable in Linux...It's painful.

As a side note...I get the part about wifi not being a robust means of COMs in an industrial environment - probably more than most. Are there plans for a Wifi3 variant? Wifi Daughter board? Inquiring minds want to know...

Yeah...'high end' is fine with me. I want the flagship model and don't mind paying for it.

I guess my point is, take any device/appliance that has/had wifi, then 'upgrade' it with better components, like the processor, drivers and IO, but then arbitrarily remove the wifi from it?...I don't get it.

I mean, why would I want to buy another Wifi 2 (which is 5yrs old now) ? No doubt, it's still a great piece of hardware...but I'd prefer the latest and greatest in Wifi form.

Imagine if they came out with a laptop that didn't support wifi - RJ45 only...BUT if you plug in a RPi to it, you can get wifi again. Right?

I'm disappointed nobody chimed in on the first post or two saying something to the effect of, "Oh yeah, the Wifi 3 is coming 2nd Q 21 - It's gonna be great!" But alas...no. 'Budget" aka 'Diet coke' mini 5 or Duet 3 with RPi are the choices.

As a customer I'm thinking to myself, "Wow this Wifi 2 is great! ~ I can hardly wait to buy a Wifi 3!" But it's not the same thing...there's not even a provision on the Duet 3 for a NRF24L01 Wireless Module to plug in ... It just seems awfully backwards to me.

I was wondering how many posts before we'd be comparing processing power of the Pi to the lunar module...

How much longer will the WiFi 2 will be produced before the end of life announcement is made? There are many printer manufacturers out there that use it currently.

@fcwilt I'm sure there are...BUT how many controllers you are likely to see sold on a commercial or industrial CNC machine use a RPi? The answer is zero.

On a 'hobby' machine, anything goes and that's where you see RPi's and Arduino based hardware. Why? The answer ALWAYS is because they are cheap to buy & no other reason.

Buhu Its too expensive.

There is a cheaper option.

But I want the expensive one

... lol + facepalm + thumb down ...

The Duet3 mini (aka 5LC) is the next version of the Duet 2 Maestro, the low end, (relatively) low cost offering. So complaining about it not being as fully featured as the Duet 3 6HC or Duet 2 Wifi/Ethernet makes about as much sense as the rest of of the nonsense you're complaining about as it has a completely different customer base.

I guess I'll leave this thread by dropping the bomb that the CAN bus (currently) in use on both the Duet 3 6HC and mini is CAN-FD, so odds are it won't work with servos (but you'd know that if you bothered to search the forum)

Please - Facepalm yourself a few more times. In fact, keep doing it until I tell you to stop. You didn't comprehend the 'issue'. Go read it again as you seem to have only read the parts that suit you. If you had read my post up-thread, you would get it:

2. Higher current onboard drivers for NEMA23/34 motors
3. More GPIO
   etc, etc...

I'm fully aware that the Mini 5 is wireless and has less I/O and processor speed than the Duet 3. I don't want it. It doesn't have enough I/O and the onboard drivers don't have enough amps for the motors I want to run. I have already stated this up-thread.

Furthermore - to get what I want in the latest form - it's twice the cost. Somehow me pointing that out is now whining? What do you think that the price is going to come down because I pointed out a simple observation? The price is what it is - doesn't mean I have to like it - AND it doesn't give you carte blanche to be a douche. Take it down a notch.

@oliof said in Where's the Duet Wifi 3?:

if you don't waste the RAM chips, you can still get an RPi4 for 35$.

Thanks for that. Looks like a 2GB Pi4 is $35ish - I'd get the 8GB one because more is "more better" as they say

@Veti said in Where's the Duet Wifi 3?:

you are complaining that the duet 3 with features that not everyone needs is to expensive, yet for you the mini 5 wifi does not have enought features for you.

take your pick really.

My pick would be a Wifi 3...which would be the natural progression from the Wifi 2. To use the analogy again: If you bought an XYZ brand laptop in 2020 for $400 - and then wanted to get another one in 2021 that was supposed to be 'updated' - EXCEPT it doesn't come with wifi anymore - you have to buy a 3rd party add on to get it - oh and it's total cost is now $800 - would you buy it? Chances are the answer would be no.

@deckingman said in Where's the Duet Wifi 3?:

@BDubs I'll just add that the faster processor on gen 3 is actually just a number. It doesn't gain you anything. Until very recently, the maximum step pulse frequency was actually a LOT slower using RRF 3 firmware which is what you have to use with Gen 3, than it is on the older gen 2. I'm still waiting for a stable version of RRF3 to verify if the step pulse frequency is now as good as the older gen 2 product.

I assume that you've also checked out the list of firmware limitations which apply to gen 3 products but which do not apply to gen 2?

Unless you need the higher current driver's or want to run more than 12 steppers, then gen 2 remains the better choice by far (and it gives you the WiFi option without the need to add another layer of complexity and cost in the form of an SBC).

That's just my opinion of course, but I've had every version of Duet products from the earliest 06 boards to the "latest and greatest".

Thanks for that - processor, or rather pulse rate, was the original yard stick when choosing the Duet. Not the same logic as most who are in dreamworld about speed...more like being able to run say 10:1 mechanical reduction and set the driver to full stepping to mitigate the hysteresis associated with microstepping (and torque loss on top of it) - but that's crazy talk because few can ever fathom what I just wrote and the reason behind it.

I'd be interested to know if RRF3 is on par with RRF2 in terms of max pulse rate, too. I'm config'd with RRF3 right now...but may go back to RRF2 after reading what you wrote.

@hackinistrator said in Where's the Duet Wifi 3?:

imho again , the main advantage of the 3rd gen board is not the drivers or the cpu . its the CAN bus .
i hope in the future there will be a possibility to connect the duet3 to industrial servo drivers , maybe device net servos also .

Yes...CANBus connectivity is nice. We'll finally be able to use those servos we hoarded off of Ebay that we swore took S&D years ago (or was that just me?)

@Phaedrux Wow dude...You rock! That was it!

I thought I uploaded them to the System folder...not sure where they got loaded to. The Macro folder?

HUGE THANK YOU!

That's a negative on all 3 counts.

However, If I click on my deployprobe macro, it deploys. Clicking on retractprobe macro, it retracts.

Do I need another M307 command for the BLT?

FYI - M98 P"config.g" does nothing when I enter it in & execute

Basically, If tell it to HomeZ (after homing X & Y individually) - it runs the nozzle into the bed.

However...If I deploy the probe pin and then run homeZ, it works as you'd expect. It touches off twice and raises the Z up. It does not retract the pin though...I have to do that manually.

Not running home all until homeZ is good - for obvious reasons.

(More on the other stuff you asked in a few min...)

For some reason, I can't seem to get my BLT working as expected. I followed the online example for wiring, Config.g et al, but I have something either transposed or wrong. Can someone take a look and see if anything sticks out?

FYI - It seems to be wired up correctly. The probe will not automatically deploy when functioning as a Z end stop/Zzero switch. However - If I manually deploy the probe via my 'deployprobe' macro, it does in fact deploy & if I command the Z to home, it does in fact work as expected. Just not sure where my code is messed up.

Yes...there's cleanup to be done deleting extra comments in the code. Thank you in advance for looking...

Just to pour some more fuel onto the angry fire...

Here's a nice little low cost device that can add wifi to an ethernet only device.

https://www.amazon.com/gp/product/B00TQEX8BO/

Where is this 'angry fire' you speak of ? Thanks for the link on the extender. (You don't think a Duet is all THAT important to me in the grand scheme of life do you? I sure hope not!)

There was a point in time where we could have a civilized discussion (on a discussion forum of all places) and listen/respect differing opinions...Only now did I notice the ability to anonymously downvote posts that don't agree with the herd mentality. That seems like a great way for cowards too inept to, agree to disagree, to bully others. It's sad really.

Anyway...I'd still love to have a Wifi 3, but until then I'll roll with the existing offerings.

Since nobody answered it - @dc42 What's the forecast look like for the Wifi 2 in terms of availability, End of life announcement etc ? Or do you see the Wifi 2 as a staple in the Duet product line for the next several (<5?) years?
