![]() You'll need to print out a BLTouch mount from Thingverse and will need some M3 bolts and nuts for the mount you choose. I haven't tried it but its cheap and easier than building your own cable so I'm putting a link here if someone wants to try it. UPDATE: I found someone selling pin 27 adapter board for the Duplicator i3 and unlike all the other pin 27 boards that only work for the Creator Ender 3, this one looks like it might be specific to i3. ![]() I'd also recommend a new 10 pin cable because I found it using a new 10 pin cable easier than to try to reuse the one already in the system. A 10 pin male cable header will be needed to wire in the sensor to the motherboard. One of the most popular choices is the BLTouch with 2M extension cable. To use sensor based leveling you'll need a sensor. After an initial procedure you won't need the Arduino any more. If you don't have one you can either buy one for around $20 or borrow one from a friend. An Arduino Uno works well for this purpose and many people already have one. To do this you will need an Arduino and some wires. Hardware NeededĪdding any of the bed leveling methods to the i3 will require you to replace the firmware on your printer. Hardwareīefore getting to far into this tutorial it should be mentioned that in addition to the i3 printer you'll also need additional hardware. ![]() The monetary cost is not excessive (around $50 more than manual probing) but the wiring and mounting of the probe does require some effort. This method uses a sensor to measure the distance between the bed and the nozzle and can optionally be added to the start of every print so that you get a great first layer every time even if your bed shifts. Sensor probing it what you want if you can afford it. For example, many people upgrade the Y carriage plate to a thicker one because plate included in with the printer is known to warp causing the bed to be difficult to level. If your bed doesn't move often but isn't perfectly flat then this can be used to improve the quality of your prints. You won't want to automatically level the bed with manual probing before each print but manual probing can still be beneficial. It is not as good as having a sensor because it is time consuming. You can use the paper test to gauge the height of multiple points on the bed to perform automatic bed leveling. This means you can get great first layer prints without a perfectly level bed. Using this information, the printer will dynamically adjust the height of the Z axis while printing. Instead a probe is used to obtain the bed height at a sampling of points. With this form of leveling the bed does not have to be level. Automatic Bed LevelingĪn even better type of leveling is automatic bed leveling. You still have to raise and lower the bed manually but the process is a lot less difficult. Leveling assist is an interactive menu that will automatically move the nozzle from one bed corner to the next at the push of a button. Some 3D printer have a software feature that is sometimes called leveling assist. Making the process more difficult, you have to manually move the nozzle to each corner of the bed by adjusting the X and Y position and you often have to do it multiple times. Typically your goal is to get a piece of paper to barely fit between the nozzle and the bed at each corner of the bed. ![]() The i3 has 4 thumbscrews that you must turn to raise or lower the bed while also moving the nozzle. For the rest of this tutorial I'll refer to the printer as an i3. In Australia the printer is sold as a Cocoon Create. The Maker Select v2.1 is a rebranded version of the Wanhao Duplicator i3 and any parts or tutorials should be interchangeable between those two printer. The Maker Select v2.1 is a different printer than the MonoPrice Maker Select Plus or Mini and should not be confused with them. This tutorial will explain how you can improve your bed leveling experience with either assisted bed leveling or fully automatic bed leveling with the addition of a BLTouch sensor. Given its 4-point bed leveling, it can be a challenge to level. The MonoPrice Maker Select v2.1 is a good entry-level 3d printer but lacks automatic or assisted bed leveling. TL DR - Add BLTouch automatic bed leveling to the Maker Select v2.1 using the stock mainboard and LCD and keeping SD card support.
