Hi, I got the hemera last year but because of time and problems unrelated to the hemera I never got it working. The problem I had at that point is now fixed, but now my motor doenst turn when doing so from the menu. It just shakes and it seems to block The nozzle is up to temp (200 c) Esteps are set to 409 Ive tried various cable configurations Mah is set to 0,94 mah in settings and saved to eeprom Really don't know what to do now
I went through this. You probably have it wired wrong... try using your factory wiring and see if the motor turns (you don't even need to have it all hooked up).
Hey guys, was there any update to this? I've been having the same issue. Wiring seems to be correct, unless the part that goes into the board needs to be re-pinned. Updating the driver current seems to have made it "attempt" to turn more, which leads me to believe that the wiring is correct. For myself, I've only got the stepper motor connected to the Hemera, no heater block / heat break - as originally I thought something was stuck inside the extruder. I've also taken off the heatsink to check the inside, and nothing seems stuck - I'm able to spin the gear on the back with my thumb with a little pressue.
So! Turns out that the I had to re-pin two of the wires in the connector that goes into the board. Asked around on the Discord and here's a little diagram someone sent over: For me, I had to swap over the blue and red wires. Hope this helps!
Unfortunately I have the same issue, tried the combo in the diagram as well as the swap you suggested, but it does nothing just click click and that's it then doesn't react anymore. Got an Ender 5 too. Anyone else have bright ideas?
This is driving me nuts. I've got an Ender 3 pro with an SKR e3 mini v2 and a Hemera. One day, the Hemera extrudes fine. The next, it vibrates. The current in firmware is 846, but I've adjusted up to 910. I've rewired the connector as shown above, as well as with the swapped middle wires as suggested on the official E3D hemera troubleshooting steps. But it... just... keeps... happening. I'm about ready to toss the Hemera and go for a bondtech mix.
Hi! Same here - I've got an Ender 3 pro with an SKR e3 mini v2 and a Hemera also set it up on 846 and vibrates only. Is there any solution?
That image doesn't appear to be a v2 e3 mini, but a v1 or a v1.2? In a sort of terrible way, that's not a terrible thing for the v2 as apparently the pinouts pdf is WRONG for the v2 and the EM pinouts should be as for the v1 and v1.2. But, according to E3D's datasheet on the Hemera connector to the motor found here (https://e3d-online.dozuki.com/Document/GdYIUZMlaEoWbQhU/Hemera-Datasheet-(Edition-2).pdf), it says that: blue = A/1A red = A'/2A green = B/1B black = B'/2B And that's the order, from right to left, that you have above. blue, red, green, black = 1A 2A 1B 2B BUT... The pinout pdf for the v1.2 would suggest it should be, right to left: black, red, blue, green = 2B 2A 1A 1B While the pinout for the (supposedly incorrect) v2.0 should be, right to left: black, green, blue, red = 2B 1B 1A 2A On the E3D Hemera wiring guide at https://e3d-online.dozuki.com/Guide/Motor+cable+wiring/145, it says to swap the "middle", blue and green wires, if things aren't working. That results in, right to left: red, green, blue, black = 2A 1B 1A 2B This is insane. The available info on this is ALL contradictory. I've been wrestling with this with an e3 mini v2 for days now. Some of the combos above kinda work for a while, like yours, but then the Hemera motor just goes into vibro mode and stays there. It doesn't seem to overheat, it just goes nope, nope, nope. I've adjusted the vref from 840 up to 940. No apparent difference. Nothing seems mechanically flawed on the Hemera. Maybe I have to face the fact that it's a dud? Or that the e3 is whacked?
