Re: PETG print problem

Have you tried slowing down? With a 0.4mm nozzle I can't print PETG faster than 50mm/s or the extruder backs up. Maybe you just have too much back pressure and aren't extruding consistently.

Re: PETG print problem

Have you tried adding some EXTRA RESTART on the Extruder tab? Depending on setup and nozzle size I've added as much as 1.5mm of restart on a PETG print - don't think you'll need that much with a .4mm nozzle, but that's the first knob I'd turn.

Re: Issues Printing With TPU

When I was printing TPU, I found the tension of just unrolling the spool caused enough drag in the feed tube to cause underextrusion. While the print was running I would periodically unspool a small pile of filament and just keep it like that so the filament wasn't pulling the spool. Thinking about ...

Re: Drying filament under vacuum

I'm still using the vacuum pump for drying. i haven't tried adding heat as JohnSays suggested. As I mention early on, it isn't as quick as I as hoped, but it works. I recently made a drybox to use during printing with a Rubbermaid 21 cup container. https://www.amazon.com/Rubbermaid-071691428855-21-C...

Re: [SOLVED] concentric infill not following shell

A shell on a hollow cylinder is one layer inside and one layer outside. If the number of thicknesses is an odd number, the middle one will be gap fill. If the wall thickness is an even number of extrusions they will all be considered perimeters shells.

Re: Ooze from Hot End

fwiw - I bought a bag of these PEEK washers. https://www.mcmaster.com/93785A110 - I tried a couple different sizes and materials - this is what worked the best for me. They work well as a gasket between the throat tube and nozzle. A fresh one might need to be opened up with a #47 drill through the t...

Re: Pro2 Plus worth it?

While the printer hardware certainly plays a role in dimensional accuracy, there are a lot of variables in the slicing software that also come into play, so you have to know how to balance your hardware and software to get the results you need. https://forum.raise3d.com/viewtopic.php?f=8&t=5111&...

Gantry sag as seen by a BLTouch

I recently swapped out the control board in my N2 for a Duet 2 Wifi. In the process I added a BLTouch probe to the print head. One of the weaknesses of the Raise design is the 8mm rods supporting the print head. They deflect slightly with the weight of the head. This isn't usually a significant issu...

Re: The bump on the outside when printing a cup or bucket

Do the edges of the part lift from the build plate as the top layers of the base lay down? That would cause material to bunch up like that.

Re: Rough surface after first layer issue

The nozzle is pretty new, maybe a month old. I've had things print quite well with the exception of the crappy lower layers. I'm surprised the cube turned out that bad. The first layer sticks perfectly, nice and clean. Wonder if it's because of the flowrate change- first layer is 100%, then it goes...

OK - I've had issues when printing legs that joined at some point - could have applied if printing open side down.

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.

Re: The bump on the outside when printing a cup or bucket

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

Re: New issues I am getting

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.

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.

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...
