CTC 3D Nozzle calibration

thingiverse

After wrestling with ABS printing for almost a week, I finally decided to seek advice from online forums and discovered that calibrating my nozzle might be the key to ending my frustration with over-extrusion issues. Taking their suggestions into account, I began to follow some step-by-step instructions and, to my delight, achieved incredibly smooth prints instantly. Photos attached clearly show the difference between pre-calibration and post-calibration results. Below are the steps that worked for me: - To start, I apply blue painter's tape with hairspray specifically designed for ABS prints; conversely, I avoid using any type of spray when working with PLA filament. Proftweaks Setup Instructions: 1. First, I adjust my nozzle temperature according to the specific material (ABS or PLA) that I intend to calibrate for printing purposes. 2. Next, in Proftweaks, I ensure that roof and floor thickness are set at zero while keeping infill level at zero. Setting the shell count to one also gives the desired print profile for optimal ABS results. 3. Measuring my filament's diameter with precision is critical; accurately entering this measurement into Proftweaks yields reliable printing performance. 4 Carefully examining the layer width within the printer software shows that it closely matches the size of my nozzle. This is crucial in preventing over-extrusion issues commonly associated with misaligned print heads. 5 Setting a reasonable feedstock multiplier (about 0.9) and keeping speeds low is advisable, as excessively high rates often cause extrusion complications due to heat management inefficiencies. 6 Upon completing these initial adjustments, I simply execute the print command on Proftweaks, letting the nozzle accurately compensate for any misalignments found during previous prints. 7. Finally, taking precise measurements of layer width after calibration enables users to confidently make corresponding changes within the feedstock multiplier section if discrepancies arise during printing phases. Through a series of controlled tests with careful data analysis from each experiment, I achieved perfect alignment between calculated settings within proftweaks versus observed output values after calibrations. With Proftweaks setup in place, enjoying crisp, clean ABS prints has become second nature for me; its versatility ensures accurate extrusion, which results in highly consistent layers throughout every project, guaranteeing top-tier print quality on every single print.
