For anyone who is interested, replacing the 2209 drivers with 2240 drivers had no effect on the ghosting. After seeing no improvement, I decided to disassemble the entire printer and rebuild it with all of my obsessive attention to detail on high alert. I spent a few hours meticulously...

Unfortunately no. I never tried NoGuru's suggestion of using different TMC drivers, so that could be it. I've come to an uneasy peace that my machine, despite my best efforts, cannot print PIF quality parts. Every once in a while I start caring again, but my obsession is in remission right now.

This is what I think is happening...

So the ghosting is not from the x-axis, even though it only appears on y moves. I verified this by printing a 35x35x0.4 "cube" so print moves would only be along a single axis. I ran the print four times: one that only had X moves, one that only had Y moves, one that only had A moves, and one...

I have Gates idlers and pulleys, though I don't think they made any difference relative to what came in the original Formbot kit :/ Thinking through the list of things I've tried, I think drivers and extrusions/bolts are the only thing that have not been swapped for something different on my...

Yeah I use tmc autotune currently. I'll try 2240s to see if they make any difference. Do you happen to know if there is a way to run a Voron with ancient DRV8825 drivers? I have those lying around and would rather try something I have before throwing more money at my problem...I'm certainly...

Here's 3 hump.

I have not tried 3hump, but I can (printing now). MZV is what I've used for most of the printer's life, but I switched to ei to try to solve this issue. I have tried tweaking the polar angle, but nothing makes a difference. Swapping the A motor to the B spot and vice versa has no effect on the...

I have a 350 V2 with a seemingly impossible-to-solve bit of ghosting. It is immune to input shaping, doesn't seem to be related to the toolhead, and only appears on y-movements (meaning, I assume, the X axis is its origin). It is more pronounced when the toolhead is moving backwards toward...

Sorry I missed your message Dave. My thermistor is set correctly. I've verified (and tried swapping with a known Generic 3950) with no noticeable changes. My X1C hotend also behaves the same way though it heats up MUCH faster than my Dragon. Temps are PID tuned etc. For filament types, I could...

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...
