It is telling you that it needs "at least" 5 amps to run.

Hi there,
The amperage can be higher than 5 amps, just make sure the voltage is only 12v

Lol,
I suppose I want the norm to be a more robust model. I wish the norm was the RRP style hot-end or similar, but instead popularity made peek-construction hot-ends the norm.
I am hopeful that a new "popular" all-metal hot-end helps others to see the light and accept the grace of an all metal design

PTFE in Steel Part of RRP HOTEND: There is a 5mm PTFE sleeve which is inserterted into the stainless steel tube, which is in the middle of the extruder (not part of the Bowden setup)
RRP Hot end build instructions
It adds complexity, and adds some limitation to max temp.
Popularity Matters in a Niche Hobby Like This: Popularity, while not necessarily a measure of how "good" the hot-end is; it d

eMakers hot-end (I have several of them) is great but... It is 3 pieces, requires the use of a small bit of PTFE in the stainless steel collar, uses heater resistors, is not popularly used, has no wiki page, and no one out side of eMaker(aka RepRapPro) uses it.
The Prusa Nozzel, is two pieces, has no PTFE component at all, uses heater cartridges (it's a plus trust me), will be popular and used

Ease of manufacturing perhaps? Perhaps there are reasons to desire the plastic only come into contact with food grade steel?

Agree and Disagree,
On Heater Cartridges- Heater cartridges are "perfectly" round allowing for easy/easier install in the heater block. Heater resistors are blobby/wobbly pieces of crap, which never perfectly fit into any circle. This design in particular allows easy exchange of heater cartridge via a screw in the heater block, which is nice. I have lost a few heater blocks to dead heater-resi

Any further exploration on the topic? What exactly (part number etc.) is used on the Prusa i3?
Did VDX name a specific viable tube to use?

Well, I might be pointing you in the wrong direction but adding some kind of z-stabilizer to your printer proabbly could not hurt anything (and hopefully help)

So is the Prusa i3 actually out or not? The build instructions are vague and unfinished. I can't tell what kind of coupling is used on the z-axis. Also, the special "Prusa Nozzel" does not exist yet...
Is it still in some kind of beta phase?

Lol, I personally have no real drive to print in peek
The concept of using a next gen hot-end to print the type of hot ends we use now is certainly fun

So if you can print in PEEK... you could print yourself a J-Head hot-end for printing PLA... EPIC

If you have not already, check out the announcement for Josef Prusa's next generation hot-end. It looks to be a nice all-metal construction hot-end. It uses a heater cartridge instead of a heater resistor. It boasts to be a good solution (extra hot) for printing in Nylon, Peek and polycarbonate.
You can catch glimpses of this bad boy in some of Josef's newer YouTu

I give him props for tooling around on the bottom end of the spectrum

Hi All,
I am ready to have my hand at home-made extruder making.
I was wondering what you consider the best/cheap source of raw aluminum bars/rods for making heater blocks etc.
Thanks for your thoughts

@NopHead
I will probably try out the printer "as is" at first, but will probably make tweaks and changes over time.
Right off the bat, are there any changes you would make to the design?

Awesome Cameron,
Thanks so much for your insights on the matter. I would love to check out your custom printed piece. Can I find it online or should I PM you my email address?

Good question. I have been wondering about this too. I have not yet seen anyone smooth a PLA print the way I have seen ABS dunked in acetone.
Perhaps a heat gun could be used??? But that would be more of an art than a science.
I would love to see what people come up with

Personally, I have only ever used the RRP style (6mm hobbed bolt) extruders with 1.7mm filament.
I have never used a carriage mounted extruder to push 1.7mm filament. I have never seen 8mm hobbed bolts that have a groove cut into them for purely for 1.7mm.

I have in my possession on of these bad boys: A 1.75mm E3D All-Metal Hot-End
I am trying to decide how to best implement this in a Prusa-esque build. The E3D Boys apparently drop this into the version of the Wades Extruder that Nophead bundled with the Mendel90. It looks like two m3 bolts are what holds it in place.
I would like to hear your thoughts. What extruder you think would best sui

RepRapPro (Adrian Bowyer and Company) released a video about multi-color printing.
RepRapPro Video
At time 6:43 we get a glimpse of an unknown extruder.
On the RepRapPro GitHub, I was able to find the extruder body parts for this extruder, but not the gears.
Some, but not all of this extruder on github
Can anyone identify this extruder or show where all of its STLs are available?

I imagine you could be right. But then again, perhaps because it uses drive screws instead if belts, the careful acceleration of marlin may not be as important?

A friend just pointed out to me that the 3D Printer upstart "MakiBox" which was crowd funded earlier this year, opened its online store on Christmas Day.
They have their mini-flagship complete printer set for sale at $200... WHAT!?
The printer is tiny but still manages a build area of 110mm x 150mm x 90mm (X,Y,Z). The $200 version does not have a heated bed; there is a $300

I love the ideas that went into MendelMax 2.0
I dig the idea of parts that can be printed or cut from sheets (depending on what is available to you). I bet laser cut plywood would work with this build...
This reminds me that I want to attempt the 3D print the Laser Cut version of the Printrbot I know a few folks were trying.

Fair enough.
I still hoped you would watch the video and come back and tell us something like "gears are so 15th century" or "I can't believe he is powering it with electricity"
