Is G-code read line by line?

I am trying to add the line G4 P4000 G1 F4000 E-50 to pause and retract the print in order for the printed line to dry (printing in mid air vertically). Does the above code work or should i skip lines or does it not matter at all? G4 P4000 G1…

Using heat-set inserts with SLA printed part

I have an SLA printed part I want to put a brass threaded insert in using a soldering iron. The insert is slightly larger than the hole so I would assume the edge will melt and re-freeze around the teeth. Are there any issues with melting SLA or…

Geeetech Prusa i3 Extruder seems to push more filament, gear slips/skips?

I got my first printer, a Geeetech Prusa i3, and for the price I paid (160$) I am so blown away. As I saved so much money, I treated myself to a legit copy of Simplify3D, which I am happy with. I'm using white PLA filament (supposedly 1.75 mm) with…

FreeCAD to design moving parts

I am trying to create a mechanism with moving parts, and would like to see how it works (whether it even works) before printing it. For example, there's a servo with a bracket, and I would like to see how far can the bracket move before colliding…

20x20x20 calibration cube size change after switching filament

I used to print with PLA and everything in my printer was calibrated. But I got a new type of filament called Poly Hybrid from a friend of mine. When I print a 20 mm cube, the x and y axes are fine but z axis in cube is about 18 mm. Should I…

My print is warping: how can I ensure that it cools evenly?

My print is warping and I suspect it is because of uneven cooling. How can ensure my print cools evenly? Should I put a fan on the bed? Will no fan and a tall skirt help? Or are my edges curling up for another reason?

Why does my part-cooling fan cause stringing?

Really strange observation with my MP Select Mini V2 printing PLA. I've printed a dual-fan shroud so I can have a dedicated part-cooling fan. I've noticed that when I turn it on, the extruder starts stringing everywhere. Little tiny spider-web…

Relation between layer height and bond strength

I've seen many references to a FDM print being weakest in the Z axis, due to poor bonding between layers compared to the extruded walls. Thinking about optimising this for a specific material (excluding temperature and geometry), is there an…
