It Is Printing! | HevORT E3D Tool Changer | Part 3

It is printing! After a lot of work and 1 year of planning, assembling, and troubleshooting I have it printing.
There still is a lot to do, mainly in the tidying up department. The printer needs to be enclosed too, so there are still some things to consider.

All, there are many links in the description to parts, firmware, and excel sheets. Let me know if you need anything else!

[@MirageC]

This is truly impressive! Love those shiny aluminum parts and all of the engineering that went into creating this amazing machine! Keep up the good work Jordan!

[@JordanMiller1117]

Thank you Oliver, you made it possible in the first place :)

[@doodle4532]

This is giving me flash backs to when I built my heated chamber printer. It sucked but I learned so much.

[@JordanMiller1117]

Yeah I know I have some learning bumps ahead of me haha. It will be interesting.

[@ericlotze7724]

Also on the note of cooling, you've probably already seen all this, but: "247printing " and " Fail Fast!" Have documented some static fan + nozzle setups "Vez3D " Made a system utilizing a CPAP fan + tubing for part cooling as well similar to your tube idea

[@JordanMiller1117]

I have not actually. I like the CPAP idea a lot though, I will definitely check these things out. Thank you for the knowledge!

[@evanroth3235]

This is impressive, pretty hot if you ask me🤷‍♂️

[@ameliabuns4058]

Nice, you're about to have so much fun :)

[@ZoltanHoppar]

One of my concerns of water cooling is weight, and the moving head speed up-slow down cycle over high speed can be an issue. I have seen Japanese tech, where the head is a laser head that melts the metal with the same feeding mechanism to solder down precisely chip legs, but for plastic I think don't necessary to have that much energy. IF it is possible to use laser mechanics to melt plastic we can have an unique head that not only will be able to make home SMT, else the plastic/a.s.o. material chassis/part of the product too.

[@JordanMiller1117]

Yeah that would be cool. My goal with the Mosquito Liquid is not to go fast, PEEK (my goal to print) doesn't like to print fast anyhow. Yes it is heavy, but it has a specialty purpose. Additionally that's why I have a toolchanger so I can grab a very light hotend :)

[@stefanguiton]

Cool stuff! Subbed

[@JordanMiller1117]

Thank you, I appreciate it!

[@Dave-wv9vc]

excellent dude, hopefully your keeping a BOM somewhere for those of us who might want to try adding tool changing to our Hevorts

[@JordanMiller1117]

I do and I will link that tomorrow, good reminder.

[@JordanMiller1117]

Check the video description :)

[@TommiHonkonen]

2:23 now kids, that is what a pull out looks like

[@ericlotze7724]

It may be a bit late to say this, but have you considered the DiamondBack Nozzle instead of the Olsson Ruby?

[@JordanMiller1117]

I just found the diamondback company at the Rapid+TCT show in Detroit and have one in my possession. Going to do a video on side by side comparison. From what I’ve seen of us using them at work I am very impressed.

[@tanatornpravalpadd2835]

Great work! Be careful with your x belt if it not parallel it might cause some tension issue and inaccurrency print

[@JordanMiller1117]

Yes, exactly. I’ve let it go for now but am going to re-design the piece to make them parallel.

[@jeroen9424]

What is that squeek you hear the printer make during the print later into the video? The sound happens during a move, but what part of the printer squeeks?

[@JordanMiller1117]

I am pretty sure it is one of the pulleys just rubbing on the plastic mount a little bit. I haven’t investigated it very much, but plan to do so. Not too worried about it at the moment.

[@madcactusvideos120]

As you add tools how are you going to keep the different tool's waterlines, electrical cables, and filament from tangling?

[@JordanMiller1117]

Cable chains or snake skin, organization I haven't got to yet :)

[@filipimDgaita]

Great work man! I am trying my own tool changer design right now. How do you do the 3 axis autoleveling (talking about firmware level)? Can you share your firmware?

[@JordanMiller1117]

I can upload that tomorrow, I'll let you know where I upload it! You can look at HevORT's website and his config.g file, I just copied that and tweaked my locations a bit.

[@filipimDgaita]

@@JordanMiller1117 thank you! I'll look at hevort too. Looking forward to see yours tho

[@JordanMiller1117]

Check the bottom of the description for the firmware :)

[@filipimDgaita]

@@JordanMiller1117 thank you so much! It Will help me a Lot 😄😄

[@finlandskis2958]

Did you make your tool changer or order from e3d? I will be calling e3d if mine isn't working.

[@JordanMiller1117]

I ordered the tool head and tool plates from them. The X-Axis cross member was custom machined.

[@gold-junge91]

Why not a washer ? For the spring, this how I make it

[@JordanMiller1117]

The "washer" is more of an open bearing, there are a top and bottom with the ball bearing inner race sandwiched between them. Or are you talking about a wave washer?

[@gold-junge91]

@@JordanMiller1117 no you can put a m4 washer with bigger id as the shaft behind the spring with this you increase the force that’s hold your tool

[@thaismoraes1715]

Is there any possibility of purchasing your machine project?

[@JordanMiller1117]

Where do you live?

[@JordanMiller1117]

I am interested

[@thaismoraes1715]

I sent you an email, but you didn't respond! please give me your WhatsApp.
