Well, nothing seemed to help, so I'm throwing more money at it. I have a Bambu X1C hotend on it's way from China. Though I have strong doubts that my hotends are faulty, I have no clue what else could be causing this.

That's an interesting thought, though I'm almost positive that the G2 design is such that there isn't really any way the housing could bind the drive gear unless the screws were so over tightened that the plastic started deforming in a way similar to an elephant foot. Either way, I'll give it a...

Damn... No change. Swapping the PTFE was the first original test I've tried. I was really hoping... Part of me thinks it might be a power issue at this point. I get weird artefacts that cannot be explained with resonance testing, and I get "timer too close" errors from my pi from time to time...

Interestingly enough, it appears to be marginally worse at 0.8A

The PTFE in my toolhead is Capricorn brand. My reverse Bowden is 3mm Chinese stuff. I've tried three different heatbreaks (dragon standard, dragon HF and V6 titanium). The motor is running at the stock G2 0.6A. I can try higher current for the purposes of the test, but other G2 users can push...

It may be worth noting that this issue also happens when I fully swap my hotend for a cloned V6. It has been a while since I've tested other extruders, but in addition to the G2 currently mounted, I have a fully assembled G1 and a CW2 I could swap in.

Extruding with the hotend hanging off to the side results in exactly 100mm extruded. I tested it with the same extrusion rate, and for lols I tested it at 30mm/s. Both extruded 100mm of filament.

Here is the test (Ellis' tape method starting at 120mm) repeated with a never used standard brass nozzle. Plastic was extruded at 240°C and 5mm/s linear, 12mm³/s volumetric.

I'm using the version that Trianglelab sold two years ago. It has a copper heat block plated in something more durable. My nozzle is a Trianglelab diamond tipped nozzle that is also plated copper and has copycat CHT internal geometry. I've used a dragon HF core before, and it also struggles to...

Does anyone know what could be preventing my Dragon hot end from extruding to its potential? Printing with ABS, I get significant die swell and my Galileo2 can only push 93 of the requested 100mm when extruding into open air at 10 mm³/s. Brand new nozzles don't help, and it still cannot push the...

Cura sliced gcode still has the bump (see below). I feel that is evidence enough to say this is definitely mechanical in nature.

Yeah I think that is worth trying. I am using the most recent version of Prusa Slicer at the moment. I think Cura would give the most different results, but do you think something like Orca would be different enough from Prusa?

I appreciate that. I'm hoping I've overlooked something. My AB motors are the BOM OMC motors with TMC 2209's and I notice no differences when using TMC Autotune. In the past few days I've also tried swapping my front idlers for BFI's, swapping my AB mounts for pins mod mounts, swapping my...

It is a Formbot kit that has basically had everything on the gantry replaced with self sourced parts. When I print slower, the resonance goes away, but the overshooting does not. Basically, on cylinders, I get something like the right image instead of the left (arrows indicate printing...

Yes, the machine is fully tuned. I can do every part of Ellis' guide by memory at this point. I've spent maybe 30+ hours trying to tune this issue out of this machine to no avail. I've also replaced every part that I feel could contribute to this issue, but it remains. My machine has some...
