Vulcanus MAX - CoreXY Aluminum Frame 3D Printer Scale UP





Introduction: Vulcanus MAX - CoreXY Aluminum Frame 3D Printer Scale UP

About: Do not follow the ideas of others, but learn to listen to the voice within yourself. Aldric Negrier aldricnegrier

On May 11, 2015 vulcaman published the Vulcanus V1 3D printer on his instructables channel. Coincidentally reprapalgarve was working on a coreXY project and when we saw Vulcanus V1 we immediately jumped on to the wagon.

With the experience we had scaling up the Prusa i3 (called Mega Prusa i3) we redesigned the Vulcanus V1 parts in order to allow 32x32x32, 42x42x42 and 52x52x52 (this last version still untested).

The Vulcanus Max 30 has a 32x32x32 build volume, E3D V6 lite extruder, auto bed leveling and MK8 Direct Drive system.

The Vulcanus Max 40 has a 42x42x42 build volume, E3D V6 lite extruder, auto bed leveling and MK8 Direct Drive system.

In summary, Vulcanus Max is a scaled up version of Vulcanus V1 with structural upgrades, all metal direct drive, auto-bed leveling, LM10UU bearings and LMK12L Z bearings and colorful lava like acrylic panels.

Have a look at the video of the V MAX in action at the Maker Faire Lisbon 2015:

Step 1: Open Design - Vulcanus Max 30 and Vulcanus Max 40

A RepRap 3D printer is always open design so please feel free to download the sketchup file. All dimensions are in 1 to 1 scale.

There are 2 versions we have tested, and are working 100%. Vulcanus MAX 30 and Vulcanus MAX 40, we are still working on the Vulcanus MEGA MAX (52x52x150) so keep tuned in.

Use the sketchup for dimensions, and the Vulcanus V1 instructions to guide your way through the build process.

Step 2: How to Build the Vulcanus MAX 30 Anbd MAX 40

In order to avoid repetition, this instructable will not contain a copy of the V1 instructions, so please visit the Vulcanus V1 for all instructions.

Start off by , opening the 3D sketchup in the previous step. There you can find all dimensions from smooth rods, aluminum profiles, and acrylic panels. Use the sketch as much as possible to obtain all relevant information.

The build process is the same as V1, using materials and parts from V MAX.

Step 3: List of Diferent Parts From Vulcanus V1

Due to many requests Here is BOM made by user weissman258:

Vulcanus Max 30 and 40 are upscale from Vulcanus V1 3D printer, so most of the parts are different:

- Z smooth rods are 12mm instead of 8mm (for rigidity).

- XY smooth rods are 10mm instead of 8mm (for rigidity).

- XY bearings are LM10UU instead of LM8UU.

- Z bearings are LMK12L instead of LM8UU.

- Extruder is MK8 Direct Drive instead of original Vulcanus V1 extruder.

- All parts where redesigned to allow bigger bearings and bigger rods, with the exception of the corners and the Z motor holders.

- The aluminum print plate is 5mm thick.

- Red acrylic panels instead of metal ones.

- LED strip on top and in the bottom of the second base.

- The V MAX's use inductive sensors for autobed leveling.

- Using repetier firmware instead of Marlin firmware (because i am more used to repetier).

Step 4: Download All Files From Thingiverse

All files are available on thingiverse:

All parts fit both Vulcanus MAX 30 and 40.

Step 5: Silicone Heat Bed

The VMAX's have a 40x40cm 800W silicone heat bed. The bed is attached to the aluminum plate using height temperature silicone. After ataching the silicone to the aluminium, you need to wire the cables to the Solid State Relay.

Step 6: Solid State Relay

The solid state relay function on the printer is to turn the silicone Heat bed on and off.

Step 7: Double Extruder

Still testing this.

Step 8: COREXY Bearing Updates

Vulcanus 1 uses 2 bearings on the XY system, this solution allows the belts to move freely on the bearings, but because of this freedom, the belts touch each other while the XY is working. To solve this problem, we have discovered that only one bearing work perfectly and allows the system to avoid the belts touching.

Step 9: Some 3d Printed Parts

Here are some photos of the first prints. More to come soon.

Step 10: More Photos of the Machines

Step 11: Repetier Firmware for Arduino Mega

Please download the firmware for the VMAX 30 or VMAX 40 according to your machine. The firmware is Repetier firmware.

NOTE: USE Arduino IDE 1.0.5 r2

Step 12: Vulcanus Max 30 and MAX40 at the Lisbon Maker Faire 2015

The Vulanus Max 30 and 40 where at the Lisbon Maker Faire 2015, the feedback was very positive, at the evening the LED's where a jaw dropper.

We finish off this instructable thanking all reprap community and a special thanks to vulcaman for publishing the Vulcanus V1.

Question 2 months ago

I'm putting one of these together (VMAX 40) and have almost everything now, but need to get acrylic and aluminium cut. Are there any files for that? Has anyone used a service to get these done? How are you guys getting these made?


Really wanted to make the MAX 40, priced my BOM, not to bad then got quotes on the printed parts, WOW at least 3 times the cost of a Folger Tech FT-5 large scale 3D printer kits with postage, that's just for the printed parts.

Does anyone have a cheaper solution for the printed parts?

I finally got around to posting on my vulcanus printer, I finished mine about two weeks ago and its running perfect on marlin firmware. The bed size works out to 350mm square along with a 500watt 240volt silicone heater it did take awhile to get it setup right for the auto bed level but now I wouldn't use it without it. Thanks for a great design.

Hi can you send marlin firmware pls?

Can you upload the Marlin Firmware you use Please ?

I have sent you the firmware via your email, Hope it works for you.

Thanks you , It's much better than repetier , work like a charm :)

I'm pleased the marlin firmware is working for you, my vulcanus prints far better than my ctc /flashforge in terms of layer height and the quality of the prints.

can i get marlin firmware i got build this printer thx

sory i forgot type my email thx

is that any change you still have the firmware can you send it to me?

can you send me the firmware too

can you send me too the marlin firmware

Can you upload the marlin firmware you send plase

Hey there! I am working on building a Vulcanus Max as well. Can you email me the firmware? I know it's been awhile since you commented, but it would be greatly appreciated. Thank you!

Email is

Very nice, congratulations :) thanks for sharing the photos.

Yeah I'm pleased with the outcome, still lots to finish yet like making the top to seal it all up for ABS prints and adding bifold doors to the front/sides. here's one more pic that gives an idea of the parts for the vulcanus. I did the printed parts on my CTC/Flashforge clone In Luminous blue Abs at 50% infill.
