3.0mm hot end replacement

Hi guys,

Is it possible for me to change the hot end from 1.75mm to 3mm?

If possible, how troublesome would it be?

Thanks

 

The team was originally using 3mm I believe, So the extruder may be able to work with it. Is there a particular reason why you want 3mm? Most people are moving away from it 3mm now that 1.75mm filament is cheaper/same price.

 

The extruder body itself will except 3mm filament so that is not a problem, the hot end however will probably not.

You would need to change to 3mm hotend. Which is easy, just remove two screws that hold the 1.75 hot end, and install 3mm hot end.

 

Oh really? I can't seem to find a cheap place to purchase 1.75mm filaments.. The cheapest I found for 3.0mm filament including worldwide shipping is from here :

Does any 3.0mm hot end would just fit into the robo3dprinter? Sorry I'm quite new to the 3d printing scene

 

you could always buy the 3mm and run it through a filastruder if you had one

 

That's $15 with shipping? Wow, I'm not sure if I would even trust that filament :/

 

Not really though.. I got it $52 for 2kg including shipping..

 

Cheap filament just gives headaches, at least from my experience. As to a 3mm hot end, I would like to be able to run that size filament as well, since my current printer has a 3mm, and I have about 10 pounds of filament I would like to use up before buying more.

 

Figure it isn’t a bad idea to put a pseudo legal disclaimer in my posts in case I steer someone wrong.

 

Is it because of the inconsistency in the diameter across the filament? Do you think an extruder might fix it?

which 3.0mm hot end would you get for the robo 3d printer?

 

I'm not sure, on my prusa right now I have a J-head http://www.makerfarm.com/index.php/hot-end-parts/j-head-mk-iv-b-hot-end-for-3mm-filament.html I'm not sure if it will work on the robo3d. When I get mine I'm going to give it a try before I buy a different hot end. To be honest I haven't done any research into if it will work or not with the robos extruder

 

www.hotends.com, these are the original jheads not clones.

 

Is that site safe to go to at work…. Sure doesn’t sound like it

 

Since I’m being lazy and don’t want to search. What extruder design is the printer coming with? For some reason the Gregs design pops into my head, but I’m not sure. I was thinking that it might be possible that the Jhead I have right now will work on the Robo, and if it does then I can save on filament for a while or buy a second hot end to have 2 printers running.

 

if its the standard jhead it will fit.
