David is awesome. I'm maxing out the Duet -- I'm loving the flexibility. He added y axis mapping(for dual Y gantries) in 2 days when I asked for it last year -- that short he described has actually happened to me where the sleeve from the heater cartridge wire pulled up and shorted to the volcano block (old style) which had a short to the thermistor and killed one of my smoothie boards -- a resetable fuse is brilliant, and detecting the fault and having the firmware report it, wow didn't know my board does that! If you excuse me, but I'm just going to take his word for it -- I check my heater blocks for shorts when assembling now, so I'm not risking that.
It's a long video! Here's where to find what: 0:49 RepRap Sells Mendel 1:32 Mini Hangprinter 2:15 Hangprinter interview with Torbjørn Ludvigsen 6:26 E3D Toolchanger interview with Sanjay Mortimer 10:39 Duet v2 and Maestro Interview with David Crocker
Love the DUET boards, they are way ahead of any other competitor. I'm very grateful for all the hard work David has put into the development of the DUET controllers. I have been hoping for a lower cost version and am very excited to see the new version 3 boards. Keep it up David!
David is a great guy. I think maestro is going to be cheaper than duet, ain't it? I am very glad i kicked the bucket and got me a duet board. I am very happy with my decision!
I discovered Duet3D in your MRRF2018 video, since then, I bought one, and installed it on my printrbot simple metal ! Amazing stuff ! It's the first time that I "hear" these new trinamic drivers, and I'm blown away ! And what a joy to use: the web interface is soooo practical ! I'm a fan now :-D
A few seconds per data sample. We used 13 samples. A few minutes to paste sample data into the script. A few seconds to run the script. Copy the M665 output from the script into Pronterface. Send. M500. Send. Done =D Aiming for one click anchor location calibration + optional camera feedback this year.
Sounds awesome. I would like to do some testing with the mechaduino, $49 each is a little steep. I am hoping they will become a little more popular and the prices will come down.
Me too. I'm a bit surprised they have stayed expensive for as long as they have. Waiting for them to get in stock and through customs almost made me a Mechaduino supplier myself. If Mechaduino price remains a threshold to closed-loop adoption we should maybe try to build encoder-only PCBs, and do all the closed-loop computation directly in firmware, using a beefier 32-bit micro-controller...
The vacuum is a very nice addition to the E3D "Medusa"! (There you go, it has a name now.) All that waste filament piled up inside the box at MRRF was messy. Great to see the Duet3D folks in attendance. Their boards are a big favorite among the Marlin geeks.
Dual G-code streams on a CAN bus with unlimited steppers... under full script control... Take My Money!!! Wow, Thanks Tom for the excellent interviews.
Oh God, the Duet segment had me sweating since I basically just shelled out for my first Duet a couple of months ago, but I see that while a lower cost board would have been nice I'm not missing out on anything and even the Duet 3 seems like it won't be aimed at my class of printer so thank goodness.
Those transitions. HP->E3D and E3D->David. Smooth. And then David mentioning the 7 stepper extensions on DuetWifi. They are perfect for connecting Mechaduinos onto. I guess we'll have five soldered TMC2660s left over for all the Hangprinter v4 tool heads then ;)
Not gonna lie, turned in solely for the duet. Man I love my wifi. Mind blown when I learned how to re assign pins to control the servo on the bltouch using simple g code commands. Oh yea, and the lack of click wheel goodness 8 bit boards have is a godsend. Nothing better than controlling my printer fem my phone. No raspberry pi to set up, no fumbling with sd cards or USB cables. Just hit upload and print, watch it on the built in webcam support on the web based interface, and print tons of vases.
Vape Scaped How fast is the wifi file transfer on the Duet? I bought a Smoothieware clone and it takes ages to transfer files over Ethernet. I should have went with the Duet but the price of the board was almost as much as my project printer. That cheaper Duet looks like it's going to be perfect for my cheap machine.
Nice! I will definitely look into getting the cheaper Duet once it's available. The Smoothieware clone disappointed me, even the USB transfers were mediocre and the web interface looks like it belongs in the 90s
5mb gcode in 15 seconds is slower than expected. I test the upload speed regularly and 800kBytes/sec is typical for me, both over WiFi and over Ethernet. Sometimes I get over 1MByte/sec. A weak WiFi signal or a heavily fragmented SD card can reduce it. Using the largest possible cluster size (64Kb) on the SD card helps too.
I seem to be a month late to the party, but: Cool video, very much appreciated! I'm currently deciding on buying a Duet with extension, and hearing how far off the next version still is and that the only thing in the pipeline will be less powerful than I need (or rather: want) at the moment definitely made my decision easier. Cheers!
I'd like to go to a 3d printing expo or event but is there a calendar listing out all these events? If not then it would be an opportunity to post a list and/or map of up coming events
Hey Tom. Any chance you'll do a video on the zesty nimble extruder? Looks interesting. It's a "Remote direct drive" extruder that uses a cable to transfer motion to the extruder. The part the mounts on the printer is like 27g. I'm using a titan direct to an e3d v6. Would love to lower the weight of my hotend and reduce ringing, by switching to this, if it's as good as they say.
Looked at the hangprinter website today. It appears the project is dead. Kind of a bummer. The mechaduino boards are too expensive to make this something I want to mess with.
Thanks for your interesting video. If you supply links to the projects of the people you interview then they would get more traffic to form the people that don't take time to Google.
I wonder how much practice it took Sanjay to say 'vacuum cleaner' rather than 'hoover' when he's talking about his new feature :) In the UK we tend to call all vacuum cleaners hoovers.
They engineer and produce "one of best mainboards" but for some reason they don't send one to Tom for a review... I just don't understand why? Tom's review would have a huge effect on my purchasing decision as well as many others.
Capricorn XS gave me an instant 0.5mm reduction in retraction compared to old 2mm ID PTFE tube. It's really helpful in keeping PETG play and stringing down. Strong recommendation, I wouldn't bother building with 2mm PTFE tube again.
Running Marlin on a Duet would be like putting a Mini engine in a Porsche. Marlin is designed for 8-bit electronics, it doesn't take advantage of the benefits of a 32-bit platform.
what large OEM the Duet guy are talking about? For the Duet Maestro? oh... the video was uploaded like now... so it's not yet out :p haha next week, the 23
pls thomas can you help me get the mini hangprinter builders contact cause in my country nema motors are too expensive able to by 6 of the unipolar motors and 3d printing is too expensive except for companies i want to build a hang printer that uses recycled plastic that is all locally made pls so i need the plans and i want to improve its accuracy so i can build a better version
Hi Thomas I wanted to know how could I get in touch with you about buying a 3D Printer and just get your advice to which one is the best model and the best finished products and quality is very important to me and this is my first time getting involved with 3D printing I am trying to find away for my recovery and this is the only thing I can do I can't lift anything with my injuries I am trying to get the right person to talk to me and give me the right advice on what is the best 3D Printer to get to find the right printer to suit me and get my mind working again Thomas I hope you can make contact with me please kind Regards Teady
No one in their right mind would buy a Duet Maestro for $130 when you can get a better Duet Wifi for $120 :/ If the board costed $85, maybe worth considering but yeah, I agree the duet line is for high end users, rip peasants
You don't want stealthChop, it doesn't work on most 3D printers. The stealthChop2 mode from the 2208/2224 is stronger. Those are my drivers of choice. Panucatt sell good SD2224.
We chose TMC2660 for the Duet WiFi because the TMC2130 can't handle as much stepper motor current as the A4988 and other drivers that were popular at the time. We didn't think it made sense to bring out a board that was less capable (in terms of motor current) than every other board on the market. Whereas the TMC2660 handles more current - around 2.0A without fan cooling and 2.4A with. The TMC2130 is OK if you choose the motors carefully. Prusa has his own branded motors, so I expect he chose the winding parameters to be a good match for the TMC2130.
Bought Duet WiFi + PanelDue, yay right?! Not quite, one week later Duet kit went on eBay and I’ve become Patreon to Marlin dev fella. Hardware is great, no doubts about that. Biggest letdown - firmware. Sorry but Duet seems a bit too overhyped, but again it’s subjective - there’s good reason some people love their Duet boards.
please explain how the firmware was a let down for you -- i actually found setting it up quite easy. being able to do so with nothing but your browser adds to that. and documentation + forum cleared any of my questions...
