A-350T Print Speed Suggestions

I searched the forum, but I have not found a conclusive answer to the question of speed for the new A-350T. There’s an thread here, but it seems very focused on theoretical speeds and the physics behind stepper motors, but it’s not really providing any simple answers. It’s supposed to be faster, so I assume this means we can increase speeds in either Cura or Luban? Or am I misunderstanding what faster means here?

Since in Cura I can easily filter the features, I’ll just refer to the settings with “speed” in the title. However, these settings could also apply equally to Luban. Basically, I’m wondering if the default “High” or high quality settings are maximized, or can any of these be increased?

High - 0.08mm

  • Print Speed (what is the Luban equivalent to Print Speed?): 40mm/s
  • Infill Speed: 40mm/s
  • Wall Speed: 30mm/s
  • Outer Wall Speed: 10mm/s
  • Inner Wall Speed: 15mm/s
  • Top/Bottom Speed: 20mm/s
  • Travel Speed: 60mm/s
  • Initial Layer Speed: 20mm/s
  • Initial Layer Print Speed: 18mm/s
  • Initial Layer Travel Speed: 24mm/s
  • Start/Brim Speed: 18mm/s
  • Z Hop Speed: 10mm/s
  • Retraction Speed: 60mm/s
  • Retraction Retract Speed: 60mm/s
  • Retraction Prime Speed: 60mm/s
  • Overhanging Wall Speed: 100%
  • Small Feature Speed: 50%
  • Small Feature Initial Layer Speed: 50%

Keep in mind, faster == less quality (as a general rule, there’s a LOT of factors and sometimes slower can be worse). The high quality settings you put seem to be close to what the 0.05 Ultradetail settings are for my MK3S+ (a touch slower, but not noticeably). Your biggest gains will be in a more general or draft setup.

For example, even on my old A350, I’ve been running 0.2mm layer height at 80mm/s for perimeters, and 120mm/s infill (all the other speeds are derived from these values). On my new F350 with these settings? Accuracy is actually quite good. A calibration cube was X/Y 20mm spot on, Z was 20.3, which I haven’t done an extrusion calibration so it has a little bit of ridging on the top.

Maybe grab the settings for a Prusa Mini, apply those speeds, and see what it do! :slight_smile:

If I remember correctly, the term “faster” has been removed from the web site. I was easily printing 80mm/s with the original Linear Modules and 3D Print Module, and have not had any issues with that speed using the new modules, at no loss of quality. I am using SuperSlicer, and mostly print with my Ender 5 Plus or Elegoo Saturn (ChituBox), but I do use the Snapmaker from time to time, especially when I need a dimensionally accurate print.

If you want to use speeds beyond those that are above those that Snapmaker defines, or are publicly available, you will need to do your own experimentation and tune the settings to work with your device.

Best of luck!

The new print head can print faster because of better cooling from a new fan and ducting design. It also helps bridging. A lot of people with the original head found doing a fan mod helped, but this no longer seems necessary.

The original linear modules could already move faster for laser and cnc than is necessary for printing. My assumption is that the main reason they decided to up the lead (and by doing so the speed) of the rails was because they found that the old ones didn’t move fast enough to take advantage of the increased power of the 10w laser. Notice no change to the z-rails which don’t move during laser anyway.

I haven’t seen anything to indicate any changes have been made that would help smooth out the motion. Nothing that would affect backlash, jerk control, acceleration etc.
