Yeah, the print I was just trying printed the skirt beautifully, but as soon as it tried to start the actual 1st layer of the model, the filament just blobbed up on the nozzle.

My current Retraction settings are:

Distance - 6.5mm
Speed (Retract and Prime): 25mm/s

I can get a decent enough 1st layer sometimes, but then the nozzle (Nozzle X) clogs. I am able to clear the clog, but as soon as I try to print again, it clogs right back up.

Using PLA with a Printing Temperature of 200C and a Print Speed of 45mm/s.

Ran PID calibration as well.

When installing the heat break, I used thermal paste on the threads that went into the heat sink in an effort to help prevent this very problem. I also replaced the little fan that came with the hotend with a larger one. Parts cooling is via 2 blowers.

Not sure what lines of the config.g or config_override.g are applicable (if any).

I know Heat Creep is caused by hot end temps being too high, but if I try to run @ 190C like I did with the stock V5 hotend the printer came with, I can't get a consistent extrusion to stick to the bed.

Does anyone have any ideas of things I can try to fix the issue?

Have no idea what I did, but I reloaded my firmware and now it's working...```

Tried auto calibration again this morning and it's P1 of the bed.g that's not touching the bed. Here's the M122:

Watching the nozzle move, it seems to actually raise as it moves from P0 to P1. There's more visible space between the bed and the nozzle as it goes to P1.

This is getting frustrating as I don't know what to do and Google ain't helping much! LOL

ok. Made the change to the config.g and Point 2 still fails to hit. It's not that the probe fails to trigger, it's the nozzle never goes down far enough. lol

Point 40 of the Mesh Grid Compensation is where it stops when trying to run that.

Seems to just be the Point 2 that's not touching the bed.

Not sure what the M208 commands were for, but I tried them and no change.

Here's a quick clip showing the calibration being ran and the nozzle not touching the plate.

https://www.dropbox.com/s/as5gpwd4cs6ipm8/Delta Calibration Fail.mp4?dl=0

All 3 endstops are the same distance from the bed. That hasn't changed since I initially put the printer together in January.

I did change from a glass build surface to a magnetic sheet though.

I thought setting the the Z=0 via the G92 Z0 command would adjust for that. It seems to have worked just fine, for most of the bed, just not that southern edge.

Anycubic Kossel Linear Plus w/ Duet2 WiFi, Smart Effector, 288.15mm Hayden Magnetic Rods, E3D V6 hotend w/0.4mm Nozzle X.

Got it all put together and things are working.... For the most part...

After installing the hotend to the smart effector, I've tried running auto calibration after doing the PID tuning and setting the Z0 value via these instructions. When the probe gets to the section of the bed furthest away from the Z rail, I get this error message. So, I ran M564 S0 to disable axis limits and then moved the nozzle around to 5 points of the bed and ran G30 S-1. I got the following results:

The printer is physically level. I just can't figure out why, even with trying Mesh Leveling, the Z-Probe still doesn't hit those southern points. Any ideas on what I can try? Been without my printer for a good month or so while waiting on parts to come in and am itching to get back to it.
