Ever since the 1.7.2 / 1.7.3 updates my prints, with the v1.1 machine, have been off by .3 - .5mm (smaller); the printer was working fine on v1.7.1 and before. I have currently just been going back to the models and scaling them up to compensate. However, I've now decided to try and fix the printer by tweaking the settings in 1.7.3 to get the prints perfect again. After many tests, and trying just about every setting, I have finally got the v1.1 printer to print almost to scale. It seemed changing the MSM and Slope helped significantly, but still not perfect. I changed the MSM to 1.85 and the Slope to 1.7. This has resulted in anything higher than 1.5mm to print to scale, but anything lower than 1.5mm is still off about .3mm. This would be something I could work around, however in changing these settings it has caused prints that used to take 5-7 hours to now take 18+ hours. I was wondering if someone might be able to help me adjust the settings better to lower the print time? I have a good understanding about what each setting does, but nothing I changed seemed to have an impact until adjusting the MSM and Slope.I am using the 1:1 mix, 50 microns / slice 31.
