Hi Folks,
Sorry to bother people again, but I'm after some advice with this printer. I've recently got the Photon S, and after two weeks of printing, I still don't have what I would call a satisfactory print. I've followed guidance from these Photon Groups on Facebook (being careful to distil the info between those posting about the Photon and the Photon S), and i'm still finding relatively dissapointing prints, where I cannot get clear detail, as reducing the exposure is increasing warp, and increasing exposure is causing the parts to be oversize. Its literally down to a window of a second or two, and at either end of the window I seem to be getting extremes of the effects.
Specs,
Anycubic Photon S
Elegoo Mars ABS-like Grey Resin.
Slicer- Chitubox (medium supports, using the auto function, with some removed/replaced with better cantilvers
Layer height 0.02mm
Bottom layer count 10mm
Exposure time 8.25s (m/c rounds to 8.3)
Bottom Exposure 50s
Light-off delay 6.5s
Bottom light-off delay 0s
I've run a photon S exposure test, and although rather subjective, it indicated an exposure time of around 6s. Firmware is v5.02
The last two prints were as follows. The diesel shunter (see attached pics), 6.5s exposure printed at an angle (nose end up) at 30 degrees, the surfaces and detail were pretty good, but it was parallelogram-ed, leaning back towards the cab. The following print, I put two of the shunters on, one flat in its "normal" orientation, and the other with it stood up on the back of the cab, 8.25s exposure, the engines have ended up very different dimension-ally, and were from identical cad. Each loco is out in a variety of directions/dimensions, but anywhere from 1 to 2mm, in either length, width or height.
So I'm just wondering if anyone has any guidance, as to where I'm going wrong, as these prints and the printer itself aren't of any use to me if they can't print anywhere near remotely accurately. They’re supposed to be able to achieve better than +\-2mm surely.
