I just installed the SL1 to SL1S upgrade kit on my printer. The original screen got cracked from a print failure and I figured it was now time to install it. I bought the upgrade kit 6 months ago and wanted to get the most out of the old screen so I hadn't really touched it. Well I was being stupid. The damn thing absolutely flies. I am getting prints done in less than an hour that were 3 hour prints. The exposure time went from 7.5 seconds per layer down to 2 seconds. The tilt speed is almost scary fast. All of the printing I have done in the last 6 hours would have taken at least a day and a half with the old screen and LED array. This upgrade will pay for itself in less than a week, completely worth it.
