Touchscreen stuck in some kind of loop...

kgbengt — Mon, 15 Dec 2025 13:16:17 +0000

Hi,

I just got the SL1S-printer for my workplace and have successfully printed some parts, but now it won't work anymore..

When i try to start a new print, the display start to loop through 3-4 menus and i cant do anything but shut off.

I've done factory reset and start-up calibrations and it seems to work, but as soon as i try to print a file it starts looping again.

Anyone got an idea whats happening?

Dim/shadow area on test screen

Jono — Fri, 14 Nov 2025 04:20:41 +0000

Just bought a used SL1S from someone who runs a maker lab, they're competent and said it had maybe twenty prints on it. I'm expert in filament but new to resin.

While doing a factory reset the screen has a dark area that looks like a shadow. It's strange because the screen is clearly still displaying an image in it, and its sharp but not pixel sharp, and not rectangular.

Before I pull it apart and poke around in bits I don't understand, any ideas what this is? Asking because I didn't see any troubleshooting for the LCD test step having weird results vs not displaying at all.

TIA!

SL1S shows no sign of life.

The printer shows nothing on the screen and no fans turn on. I have 1 red led on the power board. I’ve checked the following:

1) Replaced external power brick with one from prusa

2) measured 24V on the light green connector on the power board and on the other end near main board.

3) I measure no voltage on daughter board for the power button.
4) I pulled the fuse and looks fine but still can read 24 V from light green connector with fuse removed.

What can I do to confirm if this is a main board issue or something else?

Wifi without password

Hello,

can you please someone help me? I would like to connect SL1S to Wifi in our hospital, but this network has no password. I can´t figure out how to cennect that.

Do you have anyone some tips or have same problem?

Thanks

Error #10714 after updating FW to 1.8

Rob Meades — Fri, 05 Sep 2025 08:47:47 +0000

I have just begun getting error #10714, incorrect RPM reading from UV LED fan, on my SL1. It could, of course, be a faulty fan but I am suspicious as I have just updated the SL1 FW from 1.7 to 1.8. Is anyone else using FW 1.8 on an SL1 and printing without warnings? I have ignored the error and nothing seems to have got hot.

Loud banging noise

Nushaer Abrar — Fri, 14 Mar 2025 23:04:09 +0000

Whenever I try printing a model, after 10-15 layers, the printer starts doing a loud hammering noise. After some time, I cancelled the print and I noticed the print bed was unusually hot. For the nature of my research, I require using high temperature resistant resin. I am using the ANYCUBIC RIGID 100 resin for this. I have tried several exposure settings, and none have solved this issue so far. I also tried recalibrating the printer but to no avail. I bought this printer a few months ago and I am positive there is no resin blocking the tilt platform sensor. Any help on this would be appreciated. You can watch this Video for reference.

Printing parameters:
initial layers: 20
Layer height: 0.05 mm
Initial Exposure: 25s
Layer exposure: 2.5s
printing profile: slower

First Start Calibration wont finish, stuck on Bed Tilt Timing Calibration at end of the calibration sequence. (easy solution)

Dexter — Fri, 14 Mar 2025 17:46:53 +0000

Just received my SL1S and had trouble completing the First Start Calibration because, after the last step, it would go into a bed tilt timing calibration cycle that would never complete. When canceling, the message that pops up is that the calibration process will not be completed if the step is skipped.

Solution, just ignore it and update the firmware.

After updating, you will be redirected to recalibrate. At the end, you'll notice the tilt bed timing calibration cycle no longer exists. The process would have been a lot easier, especially time saving, if that was the first step listed in the set up guidelines. Had to post this because I wasted a lot of time just following the set up guide. before downloading the firmware update, and the customer service chat kep asking me to send them pictures and videos without suggesting the update first.

Settings for ABS Like Resin?

Does anyone have a recommendation for using ABS Like resin in the SL1S?

Error code #10120

Anna — Tue, 25 Feb 2025 15:06:22 +0000

I've just replaced the screen and connected everything related to manuals. But after callibration I didn't see the Prusa logo and couldn't find the reasons of this.

Cuold you please help me to fix this problem? I've checked all joints, but the error didn't disappear.

Thank you in advance

Can a bad FEP film cause resin sensor problems when calilbrating

Colin Hamilton — Tue, 14 Jan 2025 18:56:36 +0000

I'm a complete rookie at this. I'm trying to print one of my own models in Orange resin, and basically it won't print. All I'm getting is a shadow of the shape stuck to the FEP film. I decided to calibrate again and got the Resin Sensor warning. I followed the instructions, but still get the same message.

Could it be the FEP film?
