How to decrease Print Start Time
Hello,
We recently added a CORE One to our printers at work, and it has been fantastic so far. However, we've encountered one issue: the increased start times for prints. Currently, we primarily print using ASA, and the only adjustments we've made from the default settings are adding the advanced filtration system from Prusa and implementing an XY shrinkage compensation of 0.52% for Prusament ASA. Nevertheless, it seems to take about 25 minutes for the printer to start a print due to the chamber heating process, with the "absorbing heat" phase consuming most of that time.
Is there a way to reduce this startup time? For longer prints, this isn't a concern, but we often have many 15-20 minute prints where waiting the same (or longer) time as the print itself isn’t practical.
Thanks in advance!
RE: How to decrease Print Start Time
So turn off heat absorption in the printer's gcode startup section. It's easy to do, but you have to figure it out yourself. And once you do, you'll definitely start complaining about your prints curling, not sticking to the bed, and similar complaints!
RE:
As @miroslav.h4 pointed out and unless it's a small print, ASA and PC can be problematic if there is an uneven bed temperature. As for the chamber taking time to heat up, I use an "active heater" otherwise known as a hairdryer. Of course for this to work you need to be physically at the printer.
This is what I do for the specific types of filament not prone to warping.
