Can someone show me the 2 connectors wired to work with an ezboard/ender 3? Everything seemed to be working, then the extruder was acting weird, moving back and forth instead of one direction, i plugged into my orig motor to test and same thing, so took a closer look at the wiring, and the one that comes with the hemera is very different then the one on the ender 3. why did it work for a bunch of prints? anyway, i spent a good hour making sure i got the pins right, did a 30 min test print with PETG at 240c and everything got hotter then i am comfortable with. so i want to make sure i got the wiring right. also bringing home a temp prob to see what it gets up to.
Hey. i dont have an ender 3..... but my motor is also acting weird. worked fine for a while. then acting back and forth like its jammed. i can print 5 minutes to hours before this happens... here is a youtube video look around 9-10 sec in the video think this must be the same problem you have. i can retract the filament 15 without any problem. and then extrude 15mm filament. but when i try to extrude more it stopps. i have to retract like 400mm og filament bore the jam goes away or take out my gears, then i works fines for several minutes or hours, depends how lucky i am. Still waiting for an answer from E3D about this, and i have found several users online with the same problem. have checked my gears, wireing and everything looks okey. BUT i dont know what happens in the bearings or in the motor, so im thinking the problem is in there somewhere. If you find a solution please update me. becase i tried to print the same part for 1 week now and none of the tries is successfull
Do you have the extruder cable that came with your printer? try that and see if it works, i am at work right now and can't remember what colours i put where, but the orig cable defiantly worked, i just did not want to take apart the bundle of wires again, so repinnd the one that came with the hemera, i am just looking for confirmation about what colours go where.
well my printer is homemade, and i used a Titan Aero. and used that cable, also tried to switch to the cable that came with the hemera. still same problem. so im also looking if im wireing correct since the motor stopps after a while
In terms of the motor not rotating freely, the first thing to do is switch the middle two wires for the stepper motor on the board connection side. If this doesn't resolve the issue it may be that you have a cracked gear, in this case, could you take some images of the gears and send them over to support@e3d-online.com
It works fine, i am looking for a pin wire diagram so i can make sure i wired it right. its not a cracked gear, it spins freely, not even sure where in my post would lead down that road. does e3d have a wiring schematic for its hemera extruder?
I'm looking for the hemera wiring pin out as well. No documentation was included. I just tried Daiel Rock's link: https://e3d-online.dozuki.com/Document/H4JSEgZEtxEsa5oE/Hemera-Datasheet-(Edition-1).pdf and its no longer available. Can anyone take a look at their cable, and confirm it's straight through with the 2 middle twisted? Not sure why this seems to be so secret.
Forgive me, I should clarify, I'm installing the hemera head, on my ender 3 pro, which has the original 1.1.4 board. All other axis cables are straight through with the center two twisted..
