Re: Strange first layer problem with E2. one side of models

Could also be impacted by extruder calibration and z-offset.

Re: Strange first layer problem with E2. one side of models

I don't know the E2 machine, but in my experience asymmetry usually indicates a cooling issue - where one side is getting more cooling than the other.

Re: Replacing print head linear bearings ?!?

I ended up making some retainers to hold the bearings from the outside. No play issues in my cast N2+ block. I wasn't happy with the Amazon bearings though. I decided to see how 'name brand' bearings would compare. I bought a pair of THK bearings from Misumi ($53 for the pair w/ shipping). Holy crap...

Re: Under and Over Printed Corners

Looks like you might benefit from some extra restart on the extruder tab. If it's just a little short on laying down the first bit, the error will accumulate on subsequent layers and the gap gets bigger. Once it creates a small gap the next restart doesn't have anything to land on. That can also con...

Re: Feature request: Live Z on first layer

I just swapped the control board in my N2 for a Duet 2 Wifi. The web-based control interface for the Duet has a live micro adjust for the Z - it's real nice. I don't use it much because I also installed a BL Touch probe - but when I don't quite nail the Z offset the microstep is handy.

Re: Catastrophic Printing Failure

] Is the Ally bed a standard part? Did you have it cut? The aluminum bed is not a standard part. Cast aluminum jig plate - it comes machined flat.

Re: Catastrophic Printing Failure

What material are you printing? I printed a 3KG PETG part covering nearly the entire bed a while back. I don't have the Pro - this was on an N2+. My first attempt was using a magnetic spring-steel bed and I had a similar issue. Enough warp in the part that it lifted the bed and caused the print to f...

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.

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: 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.

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...

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

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