I was recently swapping my nozzle from 0.5 to 0.4. But it was very difficult. So hopefully Lulzbot could partner with E3D and create a Revo hotend that works with 3mm filament and works on the newer printers Taz workhorse, Taz Sidekick, etc.
Would you recommend the Hemera XS Revo 1.75mm or the M175 v2 Tool Head 1.75 mm? Also can they both do probing the bed (the shiny washers at the corners of the bed)?
(Opinion for Revo)
Pros I like the Revo because it can do easy nozzle swaps.
Cons I’m not sure if I can get a warranty for it or if it might damage my printer it wouldn’t cover my printer because it’s not a Lulzbot.
(Opinion for M175)
Pros looks like it has completely removed heat creep. I can do nozzle swaps easier than a standard Lulzbot tool head right?
Cons it still needs a wrench and heating up in order to do a nozzle change.
Hm yeah Aerostruder = E3D Titan Aero, should be straightforward to change those nozzles. You heated it up to your material print temp before trying to remove?
Whenever doing this, I like to take the head off the cleat on the X-axis carriage, obviously leaving wires connected, and lay it horizontal on a little cardboard box or something so it’s easy to see what you’re doing. You need to hold the heater block with an adjustable wrench or something while you take the nozzle off with a socket or nut driver. Be careful with the heater and thermistor wires.
I wouldn’t expect e3d to ever release a 3mm version of the Revo. By design, it’s essentially one piece from feed tube to nozzle, and the exterior diameter of the top of the feed tube (highlighted here) is 3mm.
So, leaving a mere .15mm for two walls and clearance between the filament and those walls just isn’t going to happen.
e3d would have to do an entirely new setup, except for the heatercore, and the 3mm hobbyist market just isn’t big enough for it. They never made a 2.85mm Hemera, so a 2.85mm Revo is also likely to never happen.
Now, if you keep a close watch on aliexpress, there may be some 2.85mm rapid change nozzle systems that get made, but as usual for those sort of things, quality control is completely random.
I’ll keep a 2.85mm aerostruder around for when 2.85mm is super cheap or for some flexible filaments, but for everything else? Go 1.75mm.
