Why are delta bots so finicky?

I've had my anycubic kossel for a good while now, and whenever I print something, it seems like it falls out of calibration very quickly. The biggest example is that the prints tend to scale up as the print progresses, or maybe the print starts to…

Where did I go wrong by trying to add an extra motor to my board?

I'd like to add an extra motor to my board and I'm not sure where I went wrong. The motor will be used to spin a rotating wheel/carriage of potential hot ends to switch to. Because it's just a motor it doesn't need a heatrod or a temperature sensor.…

Is there any opensource software that controls the RAMPS RepRap board directly from the computer?

I'd like to find an opensource software that communicates directly with the RAMPS board (or any other 3D printer driver) without using the arduino... It doesn't matter if it runs on Windows or linux as long as it's opensource. Also, I'm not worried…

ABS is a very strong material, but it also has some downsides. One of them, which is the necessity of having a printer with enclosure, completely discouraged me from using it, as it would be a waste of money. This is quite sad, because I cannot make…
