Just wondering if anyone has had any issues with their Fuse1 printers randomly selecting things from the menu? I’ve had it on multiple occasions whilst printers have been idle overnight that things have been selected. I even had one morning where I came into a machine that had tried to run a print w…

To be honest, yes. We have found that if the Fuse is left on the camera screen and not touched for a long time, the button for priming the Fuse is virtually “pressed,” prompting the Fuse to clean the IR sensor in order to start the priming cycle. We therefore always place the Fuse on the screen wi…

Yes its commonly known as ghost touches by the formlabs techs.

Ah this is a really good tip. Thank you.

Hi @AntHope , thanks for letting us know about this phenomenon! You could try reseating the display cable. If it doesn’t help, please do open a support case here and we’ll look into this. Reseat the display cable following the instructions in the applicable guide: Fuse 1 [ EN ] Fuse 1+ 30W [ E…

We’re aware of the phantom “ghost” touches and are working to figure out what is causing them and how to prevent the…

We have two Fuse 1+ printers. One experienced ghost selection problems and one did not. Formlabs tech support asked to do a forced reinstall of the firmware (auto-update would state that it is up-to-date). Seems to have worked, but I cannot say for sure because the problem is intermittent. We keep b…

this is worrying me like crazy right now after reading several posts about this issue. I always start full chamber prints on fridays, and my fear is coming to work on a monday morning and finding a shitshow in the printers. If that happens, im gonna explode on someone for not notifying us about this…
