What’s a controller board?
The controller board (or motherboard) is the mind of the printer. It takes the instructions given to it by your pc (within the type of G-Code) and orchestrates their execution. The motherboard incorporates a microcontroller (basically a tiny, self-contained pc) and all of the circuitry wanted for operating the motors, studying the sensors, and speaking to your pc.
Why get a Smoothie board?
The Azteeg X5 Mini isn’t like most 3D printer controllers. Most boards (primarily based on the Arduino) have an 8 bit 16 Mhz Atmel AVR processor. That is roughly equal to a pc from the late 70s. The Azteeg X5 is supplied with a 32 bit 120 Mhz ARM processor. That is principally a slimmed down model of the chip that powers your mobile phone.
The X5 additionally runs a distinct firmware referred to as Smoothie. Smoothie is a brand new firmware that’s designed to make the most of trendy processors. It prides itself in it’s superior movement management, thus the Smoothie identify. The code is way cleaner than Marlin, and significantly better documented. You’ll be able to be taught extra about Smoothie at smoothieware.org.
Straightforward to make use of
Anybody who has tried to add firmware via Arduino can let you know how a lot of a trouble it’s. Arduino is a software that was made for improvement and prototyping, not for normal individuals who simply wish to get their printer working. Smoothie is totally different.
The Smoothieboard seems to your pc as a daily outdated flash drive. To replace the firmware, merely drag and drop the firmware.bin file to the drive.
Need to make a configuration change? No must recompile and reupload the firmware. There’s a file on the drive referred to as config.txt that incorporates all of your settings. You’ll be able to edit it as you’d another textual content file. The adjustments take impact when you restart your printer. Easy.
Price
Regardless of what chances are you’ll assume, the Azteeg X5 Mini truly prices lower than an equal Arduino primarily based board. The X5 is $113 whereas the Mini RAMBo is $128.
Options
Listed below are the opposite issues that make the Azteeg X5 our favourite controller board.
Networking
The X5 Mini now has an Ethernet (RJ45) jack, similar to the official Smoothieboard. Now you now not should have your printer tied to your pc with USB. You’ll be able to join it to your community and management it from anyplace in your home, and even the world. You can even test on the standing of your printer via your net browser. See the Smoothie documentation for extra on how this works.
You’ll be able to connect with your printer utilizing MatterControl’s community printing characteristic.
Tremendous Microstepping
The X5 now makes use of modular Pololu model stepper drivers, similar to the Azteeg X3 and X3 Professional. The board comes with a set of SD5984 drivers, however you should use no matter different drivers you need with it as properly. Bear in mind to solder on the additional 3 pin header for digital present management.
The place the X5 actually shines is along with the SD6128 stepper drivers. These drivers are able to 1/128th microstepping, which is 4 instances greater than the the inventory SD5984 drivers the board comes with (1/32) and possibly 8 instances greater than what you might be used to (1/16).
What’s microstepping?
The usual stepper motors utilized in most printers have 200 steps per rotation. Nonetheless, by balancing the facility fed to the motor coils, these steps could be divided up. This permits the motor to maneuver in smaller increments, and makes the general movement much less jerky and quieter.
Most different boards will not be able to using such excessive ranges of microstepping on account of processing energy limitations. The upper the extent of microstepping, the much less time there’s between steps for the processor to make calculations. The AVR boards, with a 16 Mhz processor, can not deal with greater than 1/32 microstepping at a print velocity of 150 mm/s. The Azteeg X5’s ARM chip, with a 120 Mhz processor, can deal with 1/128 stepping on the identical velocity.
Different Options
- In-built micro SD card slot.
- The Azteeg X5 is the best board to hook as much as the attractive VIKI 2.0 graphic LCD show.
- Digital present management (utilizing supported stepper drivers) lets you regulate the facility delivered to your stepper motors via software program. No want to regulate trim screws on the board.
Panucatt Azteeg X5 GT 32bit Movement Controller
Along with the Azteeg X5 Mini, Panucatt now presents the Azteeg X5 GT. The GT is a bigger board that has further stepper drivers and heaters, permitting you to run twin extruders. It has just a few different further options as properly.
- Help for Panucatt’s excessive energy Bigfoot stepper drivers.
- Magnetically remoted USB circuitry which prevents you from frying your pc in case your printer shorts out.
- Onboard 12V energy provide lets you use 12V followers and equipment with a 24V printer.
- Addon board for ethernet (not in-built).
