I once had a result similar to the one in the last photo.
For me, the cause was a used nozzle. After subconsciously printing abrasive filament.

A fresh nozzle is always worth trying with weird issues. A partial clog can be hard to diagnose and can cause all kinds of grief.

I assume you're printing this open side up.

Wondering if you're over-extruding enough that when the inner floor finishes up it's pushing out on the outer layers.

Ran test prints all day yesterday to try to home in on settings for the new set up - accel, jerk, pressure advance, and dynamic accel. I was running eSun PETG 0.4 nozzle 0.2 layer at 50mm/s and 255c. Here's where I ended up. M201 X2000 Y2000 Z250 E10000 ; acceleration M566 X400 Y400 Z10 E250 ; jerk ...

Don't know if it was replaced when you replaced the heat block, but a partially clogged nozzle would be another possibility. Can be hard to diagnose, but good prints from the other side could just be from the nozzle being clear.

Wow - amazing work!

The BLTOUCH is mounted dead center on the back of the print head. I have a 5-pin JST connector mounted behind the thermocouple board. I misjudged that location and I ended up having to make a short extender to get the BLTOUCH plugged in. IMG_3654.jpg Sorry about the sideways thumbnails. If you click...

Just got my machine up and running after a Duet install along with some other mods. Duet 2 wifi with external antenna, PT100 board for the bed heater, Thermocouple board for the extruders, & BL Touch. Also added heat/cooling to the enclosure. That is on an independent controller and not associat...

But what i did: I stop the motors with the button on the display and moved the head in xy direction to have more space. That's your mistake. The vast majority of 3D printers are using open-loop position control. The assumption is made that the steppers are not missing steps and so all the moves are...

Where does the filament density come from for this calculation. It would have to be in the gcode. Make sure you have the density set properly in your slicer.

I finally got around to digging into this. My end-goal has changed - going to install a DUET 2 WIFI board, but the requirement on the touch screen is pretty much the same. I downloaded the IMG file you linked to and dumped it on an SD card. Flipped switches accordingly, and a desktop appears. The di...

Stepper motors move in steps. The X and Y motors are moving at different speeds depending on the angle of the segment being printed. STL files have no curves, so curved edges are printed as segments of straight lines. The motors moving at different frequencies will play different 'chords' depending ...

Great job and thanks for sharing :-) Have you ever thought about water cooling? I know the Pro can be short on cooling, but I haven't had any problems with my N2/N2+. I've redesigned my cooling arrangement to (I believe) improve cooling with fans, and added programmable part cooling - a dubious on ...

There are already probes that can map out the surface of the bed. IMHO, a better solution that attempting to "calibrate" in real time while printing. A sensor that can measure your extrusion in real time, that would see all different materials and colors on all different build surfaces at ...

How 'bout if you swap X and Y motor cables on the controller board. It could be a wiring issue. I gave that a try and still got no response from the Y-axis. Can you clarify? You swapped the X and Y motor cables on the controller board. You say no response from the Y axis - do you mean the MOTOR on ...

Thank you.

Interesting arrangement. If fan #5 is cooling the cold end heatsinks, do you still need the two inboard fans? What is the noise level like? I changed my 30mm cold end fans for 40mm Noctua fans to reduce the noise, but I'm guessing your 5up squirrel cage design is loud. Valid questions - I can't say...

My MO is not generally to take an inadequate design and throw more stuff at it to solve the problem, but that's what I'm trying here. There is enough about this concept that I like, plus i have the fans. I think the issue with the hot end cooling is just that I'm drawing in the hot air rising up fro...

Just did a few slices on that one - that one looks like a candidate for a .8mm nozzle - run time might drop below an hour.

I ran one piece with the settings above. I set the extrusion width to .63mm as that eliminated the gap between shells and didn't require any fill. Printed one part in about 1 hour 20 minutes. It isn't the prettiest part I've ever made, but it looks perfectly functional, and the integrity seems great...
