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