Description
If your printer has Marlin firmware, it has a number of powerful leveling systems built In. The most powerful of these, unified bed leveling or UBL, requires a sensor of some sort. The sensor could be as simple as a limit switch or as complex as a BL Touch. The most common sensor is a capacitive probe because it requires the least wiring, is easy to mount, senses almost any material and is extremely accurate. The problem is that most printers run on 12 or 24 volts, which is used to drive the fans and the motors but only use 5 volts for the sensors and controllers. A capacitive probe, on the other hand, is rated to require 6 to 36 volts. Also, the more voltage within that range that is supplied to the sensor, the more accurate it will be and the longer sensing distance it will have. To reconcile all of these requirements, we designed a voltage regulator module that allows you to supply either 12 or 24 volts to the sensor and return only 5 volts to the sensing pin. It also makes the wiring plug-and-play rather than requiring soldering. The package includes a capacitive sensor, the voltage regulator module and the cabling you’ll need. The sensor is a standard 18 mm cylinder, making it easy to design a mount for your particular printer. All you need to add auto leveling to your printer is this electronics package, a custom-designed mount for it and the proper Marlin configuration.h.

Required some tinkering to get it running, as expected, but E3DP delivered a great setup out of the box, helped with Firmware, and made the install as painless as possible. First layers won’t be perfect without some manual leveling before the auto level, but they’ve gotten much better from where I was, and each time I get a bit closer to perfection. Overall I’d give it 4.5 stars (round up to 5!), only because of some minor firmware difficulties and no instructions/documentation included (though they’re found in the facebook group easily). The product works great and has thus far been very reliable.
