You then can refer to the Hemera documentation ( alternate link if down)įor me with TMC2208, it will tell you to use Irms (which is basically max current divided by square root of 2 with some formula) For me on the Creality Silent Board 1.1.5, Rsense=150 Most of the time, it should be '100' which is a 0.100 Ohm resistance. You can look this up online or directly on your board (the resistance close to where you plug the E stepper motor should have a number on it).

Know the 'Rsense' value installed on your board.

Know the motor drivers you have on your board (for me with a Creality Silent Board 1.1.5, that was TMC2208).Vref calibration is actually pretty simple and you don't have to be very precise! It basically just set the upper limit on what current you can send to your stepper motor without blowing it.

I couldn't find easily the documentation online about what is Vref, Irms (sometimes just called RMS) so I'm doing a full section on it so it's clear for you. 2x M4x22mm screws (if you want to be safe and not do back&forth to the store, also get some M4x20mm & M4x25mm, you can always reuse in the future).You need to add a support enforcer when printing as show here BLTouchMount.stl STL (completely changed from original to not bumps into the Y axis motor without triggering the end switch).HemeraMount.stl STL ( remix to make the BLTouch mount nut slots a bit bigger so it's easy to use even with shrinking (at the end of the day, you don't need something snug)).You'll find bellow (quick links to the stl folder) some remixed versions.

I actually used the part from E3D hemera Mount and cooler for Cr-10 and Ender 3 by Tragical which are much better and do not make you loose any build volume. (Better) Parts to print + additional hardwareĬontrary to the video, I feel like the two part build is pretty heavy and make you loose a lot of space for no reason. This is not meant to be a complete guide but a diff to the video above so you should go watch it first and then come back here.Īs a headsup, you can definitely do the installation in three steps: first the Hemera, second adding the part-cooling fan (I still had great success without a part cooling fan at first), third the BLTouch. I mostly created this because I was following Hemera to Ender 3 - Complete guide but some information was outdated hopefully this will help one or two people in the future. Hello! This repo should (hopefully) help you put an Hemera onto an Ender 3 Pro in the year 2021 in a breeze.
