What should I pay attention to after taking a 3d printer from extended storage

So I have a self build Mendel Reprap style 3d printer. I've not used it in sometime after moving house but I'm looking to use it again. What should I pay attention to before calibrating and running it again?

Is there a slicer that can set the print speed for each layer as a function of the layer area?

Is there a slicer that can set the print speed for each layer as a function of the layer area? Larger areas give the layer a longer time to cool off before the next print layer. When the layer areas start to get small (usually at toward the end of…

How to resume an unfinished project?

I was printing a lid for a box in my Ender 3 pro printer. But I don't know why it stopped printing and moved aside when it does in finished printings. This happened at midnight and I didn't see it until I woke up. In the hope for a resume I didn't…

What is the biggest size of an object that iBox Nano can print?

Since iBox Nano is the smallest public-production-available 3d Resin printer (and the cheapest so far), I assume it has a huge size limitation. So far I've only seen pictures of its outputs that are miniature things. I've never tried it nor have I…

Ender 3 pro extruder skipping steps, tried multiple things

I've already asked this question somewhere else but unfortunately I had little luck. So... my Ender 3 Pro extruder just started skipping steps, as in the gears (and the gear pinion) will rotate but the filament won't flow. It all started when I…

How to line up (x,y) print area between hardware and software?

I'm trying to line up the physical print bed of my printer (Printrbot Simple Metal) to the virtual print area of the slicer (Cura). So far, they've never been properly aligned. It was never that big a problem because, worst case scenario, my print…

Heated bed thermistor placement

I just recently upgraded my Printrbot Simple Metal with a heated bed (and longer x-axis). I looked up some tutorials, and all of them placed the thermistor as in the picture on the left below, so I did too. However, the design of the heat plate…

Where to define grid for bilinear levelling in Marlin

I'm using firmware Marlin 2.0.3 on an Anet A8 printer. I'm using a Roko SN04-N NPN bed leveller. I've managed to set up 3 points bed levelling but I wanted to try the bilinear levelling. Issue is, the sensor goes out of the aluminum bed ever so…

Methylated spirits or turpentine to clean resin printer?

I'm new to 3D printing and have bought a resin printer. Cleaning with Isopropol Alcohol seems to be the rage, however I think this is unaware of cost savings. It appears methylated spirits is ok and is 25% the cost of Isopropol Alcohol. I'm now…

In analogy to: What glues for bonding printed PLA to injection-molded plastic?, what are the best glues to use for PETG? I mostly print in PETG and have occasional failed prints which I usually reprint. But what if I'd like to repair a print e.g. a…

Is there an engineering/physics foundation for application of airbrush nozzles?

Lately I noticed that there is a new type of nozzles (called airbrush nozzles?!?) available; typically found on those online overseas vendor sites. The nozzles are advertised for usage in E3D hardware, but are not found amongst the E3D genuine…

Linear advance calibration technique

Marlin has a Linear Advance calibration pattern generator, but I find it's hard to use because: It only prints the initial layer on the bed, where bed irregularities interfere with accurate reading of it. It doesn't do proper retraction and…

Is inconsistent vertex density a bad thing?

Will an inconsistent vertex density likely introduce artifacts in a print? Or is it OK as long as it's a smooth surface?
