This is the definitive repository for config files for this printer. Firmware is not stored here!
Vulcanus Max is an open source CoreXY, large-capacity printer:
- 2020 extrusion frame
- NEMA 17 stepper motors
- Kysan 1124090: 1.5A, 4.2V, 1.8 deg
- Bondtech Extruder
- BigTree Tech SKR v1.4 (LPC1768-based)
- BigTree Tech TFT35 V3.0 Graphic Smart Display Controller https://smile.amazon.com/gp/product/B07VWF4W3J/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
- TMC2209 Drivers
- Sensorless homing (X&Y)
- BuildTak flexible build plate
- Dual E3D V6 hot ends
- Type 1 thermistor: HT-NTC100K 3950
- Use VSCode.
- Download latest Marlin, if you so choose.
- Copy latest config from source/Marlin in this repo.
- Note: often best to transfer values to new config so as to be up to date on Marlin parameters.
Connect to Z-MIN. Note: Vulcanus is wired to the Probe and Sensor, which is entirely unnecessary and should be changed to Z-MIN (2/28/21) bl red green black +---+ . | ----- +5V ----- Black -------- Brown | . | ----- SIG ----- Red -------- Black . | ----- GND ----- Green -------- Blue +---+
- W - not used (temperature sensor on Prusa printers)
- Black - SIG
- Blue - GND
- Brown - +5V
If connecting for the first time, stop looking all over the internet and worrying with that silly BTT Writer. Look at available WiFi SIDs.
- Connect to ESP3D.
- Go to 192.168.0.1
- Upload index.html.gz
- Reboot the printer
- Go to 192.168.0.1
- Follow the setup instructions
After initial configuration you'll need to reboot the printer to get the DHCP address from the display. Navigate to that IP and continue setup.
- Change Station IP Mode to Static
- Set an IP address (use OctoPi + 1)
- Set gateway IP
- Reboot the printer when done and verify static IP address is set
First time you will need to upload index.html.gz. Get it from https://github.com/luc-github/ESP3D-WEBUI. Use the default UI to upload it, then reboot.
Extruder: Do not exceed 30mm/s extraction speed. It's a geared extruder and it does not like it.
- Build with PlatformIO. Easiest to output to SD Card
- Put the MicroSD card from Build in the printer and power off/on.
- Reset the EEPROM stored settings: M502, M500, M501
Flex Plate: UBL works very well with the BuildTak flexible build plate system. A script has been configured on Octopi for this purpose.
Note on Sensorless Probing: I read that it's not that accurate enough on the Z-axis. TMC2209 on the E0, E1, and Z axis have Stallguard diagnostic pins removed.

;------------------------------------------
;--- Setup and initial probing commands ---
;------------------------------------------
;M502 ; Reset settings to configuration defaults...
;M500 ; ...and Save to EEPROM. Use this on a new install.
;M501 ; Read back in the saved EEPROM.
M117 UBL Bed Leveling...
M140 S{{ parameters.bedtemp }} ; Not required, but having the printer at temperature helps accuracy
M109 S{{ parameters.extrudertemp }} ; Not required, but having the printer at temperature helps accuracy
M190 S{{ parameters.bedtemp }} ; Wait for the bed (if not already at temperature)
G28 ; Home XYZ.
M155 S30 ; reduce temperature reporting rate
G29 P1 T ; Do automated probing of the bed.
;G29 P2 B T ; Manual probing of locations USUALLY NOT NEEDED!!!!
G29 P3 T ; Repeat until all mesh points are filled in.
#G29 T ; View the Z compensation values.
G29 S{{ parameters.slot }} ; Save UBL mesh points to EEPROM.
G29 F{{ parameters.fade }}; Set Fade Height for correction at 10.0 mm.
G29 A ; Activate the UBL System.
@BEDLEVELVISUALIZER ; tell plugin to watch for reported mesh
M420 S1 V
M500 ; Save current setup. WARNING: UBL will be active at power up, before any `G28`.
;---------------------------------------------
;--- Fine Tuning of the mesh happens below ---
;---------------------------------------------
;G26 C P5.0 F3.0 ; Produce mesh validation pattern with primed nozzle (5mm) and filament diameter 3mm
; PLA temperatures are assumed unless you specify, e.g., B 105 H 225 for ABS Plastic
;G29 P4 T ; Move nozzle to 'bad' areas and fine tune the values if needed
; Repeat G26 and G29 P4 T commands as needed.
;G29 S1 ; Save UBL mesh values to EEPROM.
;M500 ; Resave UBL's state information.
;----------------------------------------------------
;--- Use 3-point probe to transform a stored mesh ---
;----------------------------------------------------
;G29 L1 ; Load the mesh stored in slot 1 (from G29 S1)
;G29 J ; No size specified on the J option tells G29 to probe the specified 3 points
; and tilt the mesh according to what it finds.
M104 S0
M140 S0
M155 S30 ; reset temperature keepalive
Do this any time a change is made to the build surface that could change its contour. Run the script above manually, or use the custom command in Octopi.
Manually adjust every point on the mesh with a feeler gauge. From the clickwheel, find the menu item to adjust every mesh point. Adjust each to consistent clearance.
Optional: Get the mesh, load it into Excel, and create a 3D graph of the surface.
- Copy/paste the mesh data from G29 T
- Paste into Excel (see file in this repo)
- Data->Text to columns. Take defaults
- Delete columns 1 and 3
- Select data cells and sort by column A (gets rid of blanks and orients graph to match front right view of the bed)
- Create a 3D Line Chart of the bed measurements
- Preheat for PLA. Heaters (bed and hot end) should remain on. Let the bed fully soak in the heat for a few minutes
- Use the menu to execute Bed Leveling (I think this is G29)
- Make sure Bed Leveling is ON
- Adjust it before you print
- ...or double-click the knob during print and adjust (head adjusts as you turn the knob)
Contains Marlin configs.
- download a zip of the latest Marlin firmware
- Copy the file platformio.ini to the root (same level as Marlin, docs, data, lib, etc)
- Copy the latest configs to the Marlin folder within the downloaded repo
- Build using VSCode
Note: It's better to transcribe your config, editing the latest Marlin version to match. Often config directives change between releases. Same for platformio.
Latest build is in Documents/Marlin/Marlin-bugfix-2.0.x, built 4/23/2020. I was attempting to make UBL work properly. It didn't. See open issue on GitHub. Working currently on adding WiFi support.
WiFi is enabled on Serial 1

- Remote printing
Use OctoPrint to print over WiFi. The built-in camera lets you monitor your print. OctoPrint allows you to remotely control the printer.
- Heated Bed
The build surface can use the Monoprice 300x300 flexible build plate or borosilicate glass plate. Autoleveling makes print setup easier.
- Zoned Heated Bed
The 300x300mm heated bed has 3 zones, small, medium, or large, to reduce power consumption by only heating the portion of the bed that is needed based on the footprint of the model.
- Controller
32 bit processor running at 120MHz with 2209 stepper motor drivers and Marlin 2.0 firmware.
- Extruders
Dual Bowden tube extruders minimize print head mass for less vibration and faster print head movement.
- Vibration-free Frame
Dampers are used on all moving parts to reduce vibration.
- Ambient Temperature Management
Insulated side panels and an exhaust fan allow control of the ambient temperature inside the printer. A heater brings the enclosure quickly up to temperature before your print starts.
- Safety
High amperage power is isolated and protected so that an electrical fault will not cause a fire or damage to the controller.
