Have you looked at Zesty Nimble? although, sadly, I see they have had to stop shipping due to Covid.by RGN01 - General
Re: Duet Network Sucks - 6 years ago
I've been watching this thread with some amazement and, frankly, disbelief! On this forum is a folder called Electronics. The top folder within that is 'Duet' and the sticky at the top of that is by dc42 and states, simply, "Where to get help for the Duet series of 3D printer electronics" and within that is everything you need to source perhaps the best-informed, most helpful, most responsive anby RGN01 - General
Re: Remote Direct Drive effectors for E3D Chimera / Cyclops (Zesty Nimble et al) - 7 years ago
This last photo shows the filament mount with the large rollers. Also showing is the altered Y-axis motor mount and the Y-axis cable chain. The small size of the Nimbles and the angled mount Lykle and I came up with allows the carriage to have a width of only 48mm. Given how much is crammed onto that carriage, I think that is pretty impressive. Most of these parts are on Thingiverse if anyoneby RGN01 - General

Re: Remote Direct Drive effectors for E3D Chimera / Cyclops (Zesty Nimble et al) - 7 years ago
I've had a few queries about the printer I've fitted the Nimbles to so thought I'd provide a bit of detail. It started as a Prusa i3 Steel clone from a Spanish kit (can't remember the make) but pretty much only the steel frame, the Y rods and spider and the RAMPS / Arduino remain of the original. I have added a 24V PSU which supplied the 2 hot ends and the heated bed (each through an external MOby RGN01 - General
Re: Remote Direct Drive effectors for E3D Chimera / Cyclops (Zesty Nimble et al) - 7 years ago
Right, so this is a horribly rough test but what you have is a very flat H-shaped piece of Hictop TPU black rubber flexible filament printed between two clear-ish ultra cheap ABS sides. The retract settings were wrong so the black bled all over the one end of the ABS - and the ABS leaked everywhere, too! :-) Anyway, it proves that this s potentially a viable way to make hinges in items - and isby RGN01 - General

Re: Remote Direct Drive effectors for E3D Chimera / Cyclops (Zesty Nimble et al) - 7 years ago
How quickly we get spoilt! I've been experimenting with printing flexible filament so designed a captive hinge. I tried to print it and my filament out monitor stopped the print as soon as it went to the second extruder. I cursed and moaned because the Nimble hasn't failed me yet so I wasn't expecting that. Went through the process to reload the filament and tried again. Twice. And then I reaby RGN01 - General
Re: Launching a new build plate - 7 years ago
Very interested in this. It appears from the photo that the price includes adhesive. Is this correct, please? Edited to add: Also, has it been tested with David Crocker's IR sensor? Did it work? Thanks. Richardby RGN01 - General
Re: Remote Direct Drive effectors for E3D Chimera / Cyclops (Zesty Nimble et al) - 7 years ago
No, my explanation is that the roughness was due to there being too much material due to the 103% infill (100% set in the slicer plus the extra from the thicker filament) and the nozzle therefore ended up pushing though that extra causing those bumps. On the upside, though, that part is nice and strong! :-) Richardby RGN01 - General
Re: Remote Direct Drive effectors for E3D Chimera / Cyclops (Zesty Nimble et al) - 7 years ago
Now that I'm back from my holiday I can respond. All these prints were ABS, printed with 100% infill as I was going for strength over looks. Nozzle temp 260°C, 0.3mm layer height and speed of 140mm/S (as reported by CuraEngine in Repetier Host and I know that the actual print speed wasn't that high). I also found out later that the cheap ABS I used was slightly oversize (1.8mm instead of 1.75mmby RGN01 - General
Re: Remote Direct Drive effectors for E3D Chimera / Cyclops (Zesty Nimble et al) - 7 years ago
After all my mention earlier in the thread that the spring would work for the filament monitor, I was wrong! It had too much friction and was causing an oscillation of the filament monitor as the Nimble pulled it down until it overcame stiction and the monitor jumped back the 1mm or so it had been pulled down. Clearly this wasn't going to work long term so I've redesigned it and have managed to gby RGN01 - General

Mutley, your link to that tweet inadvertently explained something to me - I now understand a lot more about the motive for the deleted post that started the most recent direction of this thread. Anyway, I must clarify a few things: 1. yes, you apologised and refunded me.

Take a chill pill, Chris. :-) I have personal experience of support from both - and have used the product from one (as a direct result of a lack of communication and support I never got to try the 'other' one). Have you ever driven a car that needed a service? Well it's kinda like that - it will still get you from A to B, perhaps not quite as economically as it could but it still does the job.by RGN01 - General
Re: Remote Direct Drive effectors for E3D Chimera / Cyclops (Zesty Nimble et al) - 7 years ago
I know that there are those who seem intent on rubbishing the Nimble using this thread and others (nudge, nudge, wink, wink) but perhaps the reason that users are not posting about it is that they are too busy printing using it and enjoying doing so! To be clear, I am simply a customer with no links to either Lykle or Brian and my only interest in the Nimble is as a customer - nothing more, notby RGN01 - General

Great news - I am helping a family member build a printer (well, we are just starting to think about it) and I won't have any hesitation recommending the Nimble. I may also build another printer so we may end up ordering 4 or 5! Richardby RGN01 - General

Re: Remote Direct Drive effectors for E3D Chimera / Cyclops (Zesty Nimble et al) - 7 years ago
I remembered that I had a sample of eSun eLastic filament that I'd been waiting to try so I did. This stuff is more like an elastic band than filament! Despite this, the Nimble printed it just fine first time (once I flushed the ABS in the nozzle out with some PLA. Even better, the filament monitor worked perfectly despite it being a bit lopsided after the damage mentioned above! All very promiby RGN01 - General
Re: Remote Direct Drive effectors for E3D Chimera / Cyclops (Zesty Nimble et al) - 7 years ago
I can report that it works just fine. There is not much friction at all unless the spring is overly tight against the hobbed wheel. It needs very little force to turn it because it is just a short 3mm shaft, hob wheel and a 3D printed magnet wheel turning in 2 3mm bronze bushes. I've used it with ABS and PLA and both work fine. I guess that a rubbery, flexible filament may be more of a challengeby RGN01 - General

My Nimbles arrived today and I'm busy mounting them on the carriage. This one shows the mount for the filament monitor - it still needs the cover and magnet wheels.

One more photo to show the Chimera heatsink in the fan housing - it reminds me of a radiator in a vehicle of some type! Despite the shroud going almost all around the heatsink, there is almost no resistance to air moving past it as proved by the good old 'blow test'! Richardby RGN01 - General

So my Nimble has landed in the UK but as it is a bank holiday weekend and I'm at a conference most of next week I won't see it until Friday at least so I've been doing final prep for it by printing out some pieces to test my mount using the mock up I downloaded.

Re: Filament sensor (Zesty Nimble et al) - 7 years ago
Yes, I use 24 1mm x 2mm magnets in each wheel. These are arranged N-S-N-S facing the Hall effect sensor. My next experiment is going to be a latching Hall effect sensor. This will give a state change for each magnet and not give multiple pulses if the wheel moves backwards and forwards small amounts - for example during retracts. Really looking forward to assembling this all. Richardby RGN01 - General
Re: Filament sensor (Zesty Nimble et al) - 7 years ago
They say that a picture tells a thousand words so...... I forgot to mention earlier that air cannot escape downwards onto the heatblocks - it must exit rearwards. Oh, Lykle, I also forgot to mention that I've given up on putting the filament monitor between the Nimble and the Chimera heatsink - I just couldn't get the PTFE tube to work in a way that I was happy with. It will now go above themby RGN01 - General
Re: Filament sensor (Zesty Nimble et al) - 7 years ago
There is a 4mm gap either side of the heatsink so air is forced through the fins from the front, out the sides, and then ducted back so it remains in contact with the sides of the heatsink to continue cooling until it is finally expelled at the rear. This because the cooling effect is enhanced by keeping the air in contact with the heat source longer. I also use a slow turning, quiet, 40mm fan wby RGN01 - General
