<![CDATA[SoliForum - 3D Printing Community — mk5 melting]]> 2014-05-14T02:48:02Z PunBB https://www.soliforum.com/topic/6418/mk5-melting/ <![CDATA[Re: mk5 melting]]> Just to clarify for the OP.  With an E3d you can absolutely use a nozzle fan (g-code controllable preferred) with an MK-5 and a nozzle fan duct of your choice.  This can be done utilizing the leftover bolts from the acrylic assembly.  The E3d cooling fan is always on and usually just tied into the extruder motor cooling fan.  AZERATE is referring to a design  that rearranges things creating a replacement E3d cooling duct and moves it to the side.  To allow for the nozzle fan to be located in front.  It is a great design and I am sure it works great.  Your original question was if you could use a nozzle fan with the E3d if it also has the E3d fan?  The answer is yes but what shape and configuration is totally up to you.  I personally prefer my nozzle fan to be located behind the nozzle under the extruder carriage.  I just like being able to see the nozzle and if you can't find a duct that does what you want you can always design your own.  I hope this clarifies your options.

Sorry Photog....I forgot to add this link in my older post
Whoops!

I didn't have that experience with the bolts.  I'm pretty sure there will be enough left over from the original acrylic assembly to make things work.  I have outfitted 4 SD3's with MK5's and never had to buy new bolts yet.

For the MK5, you can cannibalize the stock 4-40 bolts. But Boz's mashup extruder which keeps the 30mm E3D fan but adds a 40mm fan for the nozzle would require shorter bolts with the stock carriages (fairly certain even with Lawsy's carriages, but would have to verify that claim). Boz designed his extruder body about 10mm(?) too deep....but this is necessary for it's function.

The MK5 is wonderful and simple. Bottom line. But unless you can design a fan mount while utilizing an E3D that does not entail robbing airflow from the cooling needed for the all metal hotend, Boz's design is the way to go for sure....especially useful if you plan on printing PLA.
If you can design said E3D dual fan mount, I would love to print one!

Can I use a nozzle fan with the e3d if it also has the e3d fan?

This is a great design.
But please take note that for this, you will either need to cut down your 4-40 bolts (the ones that go from the back of your carriage to bolt onto your extruder), or buy some from Mcmaster-carr

How so? Will I needed a different mk5¿

Case heater's to blame here then. Air temps above ambient+heat from a PEEK based hotend could get you over Tg for ABS.

Any solutions? Something I can coat the plastic in or wrap around it. The case heater really helps making the prints not warp.
