The all-new AMS lite is elegant and reliable, making multi-color 3D printing accessible to everyone. The A1 mini comes to you pre-assembled, pre-squared, and pre-tuned with precision. It only takes about 20 minutes to set up for your first print. A1 mini handles various calibrations all by itself. It meticulously calibrates the Z-offset, bed-level, vibration resonance and nozzle pressure for EVERY print job, automatically. A1 mini probes the bed with the nozzle to measure the absolute z-offset. No need to stick a paper as reference. A1 mini has sensors in toolhead and heatbed. One of the very first bed-slinger printers to run auto resonance calibration on both X & Y axes. First of its kind, A1 mini runs the nozzle pressure based flow dynamics calibration algorithm. No need to draw any pattern or get any manual pick & match involved, A1 mini handles Pressure Advanced calibration automatically. A1 mini can check the belt tension automatically through the vibration frequency calibration. If the belt is loose, the HMS system will notify you to use the auto belt tensioner to set the belt to the right tension. No manual setting involved, A1 mini fully automated the filament load/unload process.
