MatterHackers’ execs take an in-depth take a look at this fast-processing, 32-bit controller board that may assist produce cleaner 3D printed components.
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 accommodates 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 just isn’t like most 3D printer controllers. Most boards (based mostly 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 cellular phone.
The X5 additionally runs a special firmware referred to as Smoothie. Smoothie is a brand new firmware that’s designed to benefit from trendy processors. It prides itself in it’s superior movement management, thus the Smoothie title. The code is way cleaner than Marlin, and significantly better documented. You possibly can be taught extra about Smoothie at smoothieware.org.
Straightforward to make use of
Anybody who has tried to add firmware by means of Arduino can let you know how a lot of a problem it’s. Arduino is a software that was made for improvement and prototyping, not for normal individuals who simply need 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The Smoothieboard seems to your pc as a daily outdated flash drive.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 accommodates all of your settings. You possibly can edit it as you’ll another textual content file. The adjustments take impact when you restart your printer. Easy.
Value
Regardless of what it’s possible you’ll assume, the Azteeg X5 Mini truly prices lower than an equal Arduino based mostly 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 possibly can join it to your community and management it from anyplace in your own home, and even the world. You too can verify on the standing of your printer by means of your internet browser. See the Smoothie documentation for extra on how this works.
You possibly can 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 need to 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 doubtless 8 instances greater than what you’re used to (1/16).
What’s microstepping?
The usual stepper motors utilized in most printers have 200 steps per rotation. Nevertheless, by balancing the ability fed to the motor coils, these steps might 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 should not 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’t 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 similar velocity.
Different Options
- Inbuilt micro SD card slot.
- The Azteeg X5 is the simplest board to hook as much as the gorgeous VIKI 2.0 graphic LCD show.
- Digital present management (utilizing supported stepper drivers) means that you can alter the ability delivered to your stepper motors by means of 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 affords 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 a couple of 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 means that you can use 12V followers and equipment with a 24V printer.
- Addon board for ethernet (not inbuilt).
