#1 yes it's a nozzle prime. #2 Yes, there are half a dozen topics and ways to fix his discussed near weekly. 2 schools of basic thought: Adjust your limit switch and bed location arrangement such that the nozzle purges over the edge and thus just drops- and that same thought combined with always usi...

Re: IM Weirdness...

FWIW, this setting bit me the other day at the local makerspace. I was wondering why all the insane retractions and found the answer defaulted in profiles enabled.

Re: Change in print surface

Using Pro2 and eSun PLA+ filament. I made two changes to a template which had previously produced acceptable horizontal surfaces trying to stop overextrusion of support material. I changed the Support Flowrate from 100% to 95%, and the Support Speed from 50 mm/s to 60 mm/s. The print went extremely...

Re: Change in print surface

My model is 'hanging in the air' because I am trying to find settings which allow: 1. easier removal of the model from the support material; 2. better surface finish where building on support. It's an experimental issue. There are 2 major factors that affect layer bonds. This is what matters when y...

Re: Adaptive Layer Height Causing Longer Print Times

To be fair, agreed, the example in what raised showed is a poor example. A sphere is not the object to expect huge gains or savings of time on by adaptive layer height. Yes, you get some gain vs printing it all at 0.1mm layer height, but the variable layer height is just not the best gain scenario o...

Re: Adaptive Layer Height Causing Longer Print Times

Also- catch 22, remember that slicing time is an estimate. Take that seriously, it cannot and does not account for firmware based on reading the gcode, executing it, applying speed limits and acceleration/deceleration meaning actual prints nearly always take longer than any estimate. Sometimes, the ...

Re: Adaptive Layer Height Causing Longer Print Times

Keep in mind, dual extrusion is a double penatly on every layer time wise. Dual extrusion can be greater than 2X layer time penalty (say 2.5 to even 3) when switching nozzles, doing the purge wall, maybe additional support structure if that's the reason for dual extrusion- not to mention slower spee...

Re: Adaptive Layer Height Causing Longer Print Times

Think about this for a second, how on earth would adaptive layer height not take longer- compared to a typical given fixed layer height (0.2mm) print? It's as simple as this math- a layer takes X time regardless of layer height. By very definition and intention of adaptive layer height, you are inte...

Re: What is this and how do I turn it off?

It's called a wipe wall because you chose dual extrusion. It indicates you probably are making a mistake in settings for a given non dual extrusion print invoking dual extrusion for less than good reasons. In other words, you are asking the wrong question. You "want" a wipe wall anytime yo...

Again, this could be a preview error, the but the final proof is always preview gcode, zoom in and actually look in detail in these suspect areas, actually play it segment by segment on a suspected error layer and this is where while Ideamaker is OK and better than nothing, you should be using somet...

Re: Inner Shell Showing through outer, in preview - insights appreciated

My bet is repaired isn't repaired, the issue is in the STL still. I could be wrong, but just don't trust a repaired STL on certain complex textured models. I would use something like Nefabb or other tools to examine the STL (re-export the "fixed" version you are looking at), then definitel...

Was thinking of something like these. https://www.nbk1560.com/en-US/products/coupling/couplicon/jaw_type/ The problem with those is, for the Y axis, it will require clearancing the frame because they are larger outer diameter and hit the frame specially in the Y axis.

Again, the faults here of the original N series V2 hotends. The heater block is large and long making radiated heat a problem. Insulation helps, but a huge part of the problem is just the size of the block being hot. The M4 threads of thermal barrier tube are simply not strong enough under prolonged...

The special 5 axis CNC machined melt path in these nozzles mixes and flows the filament other cheaper machined nozzles that can't match.

More importantly why are these things failing left and right? Simple, motor to shaft alignment. The motor is mounted using a Z shaped bracket with plenty of room for variable alignment and only held with friction from the screws.
