Clogging? Installed brand new hotend. Didn’t have this problem until I got about 1/2 roll left. I’m thinking of a bulldog and eliminating the wades. Any thoughts?
filament diameter? it might be oblonging mid roll and having issues with getting into the hotend, just a thought.
A wade is plenty strong, if you switch to a bulldog chances are that on clogging the extruder will damage the hotend. A wade can do that already and a bulldog even more so.
It’s possible that your extruder is missing steps. Check the voltage on the stepper driver.
Maybe I forgot to check
Also have buzzing on y axis. Checked everything so ordered a new stepper
Manually feeding it extrudes fine through the hotend
you’d be surprised how little of a variance will clog a hot end or just prior. Most manufacturers first runs can be more oval than circular and that’ll cause issues with really tight hotend entrances, one operator said he drills out 1/1000s of a in (or was it mm?) of his hot end barrel and never has an issue if the filaments are oblong or vary up to 1.85 1.95. (if using 1.75) I think 3mm machines have less issues with this type of thing.
The only thing I modified was the hole in the e3d mount. Drilled it so I could run a tube inside it.
ah if you can feed it manually without too much force then the diameter is fine, so yah it might be you’re missing steps, new stepper should fix the issue.
A wade has more power than you can provide by hand, it is also faster which can contribute to clogging as well. I had several occasions where i could push filament easily by hand but still got clogging.
What’d you end up doing? I’ve had several good prints
For me it was often that heat crept up in the hotend.
If you are interested there is still a chance to participate in my second Beta run of my Bondtech extruder, see my profile for more information.

@Martin_Bondeus
How much will it be? My e3dv6s are universal
@Zane_Mitchell The beta2 price will be USD122 + shipping for a complete extruder with a geared stepper and SLS printed parts in nylon, I also provide mechanical kits if you have your own stepper and want to print the housing parts yourself, new version is universal so it can be used booth as a bowden and a direct.
Drop me an e-mail at order@bondtech.se if you are interested to participate.
If you’re missing steps you don’t replace the stepper motor. you tweak the voltage on the stepper driver. I have a printer that has steppers that are much smaller than they should be and there is no sign of them failing. (its been going like that for 2 years)
I played with it a lot last night. Ended up being the hobbed bolt. Apparently it would grip then not grip. And sometimes I couldn’t tell for atleast 50mm of filament extruded. That was what had me bedazzled.
Good to see you uncovered the cause. I once had a bolt that was threaded slightly oval, it took me a while to get that one.
You where probably over extruding to compensate. Fixing that will make a big difference.
