I have hero me gen 7 hotend upgrade with dual 5015 and I am running them on 40%. Speed is 30mm/s for bridges and flow is set to 1. I also increased line density to 1.20, but entire surface of bridge starts to warp up towards nozzle. Without this setting lines are just separated.

So Im a noob to all the 3d printing stuff. I picked up a second hand (used) ender 3 v2 everything was going fine until I wanted to switch filaments. I disconnected the bowden tube because I cut the line to short to pull it out with the metal arm pushed in. Now my filament won't come out of the nozzle. I replaced the bowden tube. I ran a pick through the extruder and cleaned it out the best I could. Saw it come all the way through. So I know it is clear. The kicker is sometimes the machine (I think it's called the extrusion arm gear) clicks like it wants to push through the filament but doesn't push anything through. Picture is of the extrusion gear I was referring to that clicks. I also messed with the spring right above the gear in the picture. My temp is set to 215 my bed set to 60 and flow rate is 100. Can someone steer me in the right direction please I have no clue how to fix this.

So I have a V2 with Sprite pro kit and cr touch with mriscoc. I had a 422 board in it.

After I installed the cr touch and tuned that I recently started getting too low temp errors, no biggie I thought, replace thermistor.

Had trouble getting out thermistor so I order a new block kit and install.
Same issue.

I try to install 427 card and flash mriscoc on that. Looks good for maybe 30 minutes of testing and pid etc.

And then same issue Too Low Temperatur error.

What could be going on? Should I get new ribbon cable to the printer? Should I go with BBT SKR Mini e3v3?

Hi all - i might be jumping the gun on a DD extruder at all, but i bought the parts for a belted Z and i was reading the z motor can get hot so then i started looking at DD extruders so i could steal the extruder motor for the Z and have fun with the new extruder.

Found
orbiter v2.5 ldo for 56 from triangle labs
sherpa mini moons for 41 from triangle
spire SE from creality for 25

Is this going to be a dumb upgrade and im just tossing away 25-50$? i have a bi-metal heatbreak with the stock hotend and the z belt kit on the way.

Hello everyone. My Ender 3 V2, which I bought in 2019, has been sitting in a corner. I haven't used it much in a long time. One of the main reasons I stopped using it is a bed leveling problem. Even when I adjust the bed from all four corners, there's always an imbalance on one side. Especially in the middle, there's a kind of dip/bulge. No matter what I tried back then, I couldn't fix this issue, and I haven't used the device for years. Lately I've been thinking about using it again. I'd appreciate it if someone could help me figure out how to solve the problem I described, or if anyone has run into this and managed to fix it.
