SUNLU T3 printer Marlin 2 configuration can be downloaded here.
This configuration fixes a bug where the extruder cooling fan would only turn on when the motors were active and not when the extruder was hot. This could lead to heat creep and a clogged hotend if the hotend heater was left on and the motors were off.
OTAs can save money when traveling but sometimes you may not get the reservation you wanted. SuperTravel OTA booked a nonexistent reservation and used the payment info on another OTA without my permission.
If you do take the chance booking travel with an OTA, make sure to pay with a credit card.
Connecting the generic 3 pin filament runout sensor to the Ultimaker Original+/2/2+ controller board or other printer without dedicated filament runout sensor pins is plug and play once the mystery runout sensor pin out is determined.
I created a adapter board for this style of filament runout sensor that minimizes wiring and uses adjacent pins on the Ultimainboard.
What does Fast Print on the SUNLU T3 3D printer actually do?
After looking through the released T3 source code, Fast Print appears to be an acceleration modifier that SUNLU had future development planned.
The SUNLU T3 is a capable 3D printer that is designed similar to the Ender 3 Pro. It’s supposed to work out of the box but the calibration and setup isn’t clearly explained for new users. The T3 prints very well after making the calibration and software tweaks in this post.
