FLSUN T1 Pro Review & Rating

Redditdiscussion

Print Quality+1 pts
Mine still prints 7-8 hour prints with very good accuracy
Reliability-1 pts
I had 2 in a row (from Amazon) that failed on the first print or first day, the 3rd one worked fine (and still is)
Build Plate & Leveling-1 pts
Bad bed adhesion after doing what's successful for cleaning for a few years.
Value & Support-1 pts
I did notice they got less and less responsive though

Flsun T1 Pro Bed Mesh Always 05 Mm Even With

Print Quality+1 pts
Using FLSun's SIZE_ANALYZE calibration, the 70 mm calibration distances went from roughly 69.0-69.4 mm to about 69.92-70.08 mm, so the dimensional correction worked extremely well.

Hi everyone, I'm trying to understand a persistent bed mesh / first-layer issue on my FLSun T1 Pro, and I'd really like to compare results with other delta owners. The printer can produce very good tall prints, with smooth and consistent layer lines from bottom to top, so mechanically it doesn't look like it has obvious play, major guide issues or serious motion problems. The strange part is the bed mesh. No matter what I do, I keep getting a mesh with roughly 0.47-0.53 mm total variation, usually with a very similar three-lobe shape. What makes it confusing is that I already tested with a glass plate, cold, on both sides, and the mesh shape remained almost the same. That makes me doubt that the mesh is showing the real physical shape of the bed. I also tested printing without bed mesh. The first layer was globally too low, but the spatial error across the bed was much smaller than I would expect from a real ~0.5 mm bed deformation. Another thing I've noticed is that the first-layer sweet spot is extremely narrow. If Z is slightly too low, I get strong surface waves / ridges that look like over-extrusion or excessive squish. But if I raise Z only a little, the extrusion lines start separating and adhesion drops. There seems to be very little usable margin between these two states. The printer uses the stock strain-gauge / load-cell bed probing system. I've already inspected the three sensors and their mounting. Probe repeatability at a fixed point is actually quite good, typically around 0.02-0.04 mm range. I also checked dimensional accuracy in XY. Initially it was clearly off. Using FLSun's SIZE_ANALYZE calibration, the 70 mm calibration distances went from roughly 69.0-69.4 mm to about 69.92-70.08 mm, so the dimensional correction worked extremely well. However, the bed mesh still remains around 0.5 mm. So my main question is: Do other FLSun / Klipper delta owners also see bed meshes with 0.4-0.6 mm variation, even when the printer itself prints well? I'm especially interested in results from T1, S1, V400, Super Racer or other Klipper-based deltas. If anyone has screenshots of their bed mesh, first-layer results, or experience with strain-gauge probing on delta printers, I'd really appreciate seeing them. Thanks! PS My printer has 700 hours of use.
