Studies show that when our brain is constantly switching gears to bounce back and forth between tasks – especially when those tasks are complex and require our active attention – we become less efficient and more likely to make a mistake.
For the rest of us, our attempts to do multiple activities at once aren’t actually that. One study found that just 2.5% of people are able to multitask effectively. “When we think we’re multitasking, most often we aren’t really doing two things at once, but instead, we’re doing individual actions in rapid succession, or task-switching,” she says. We’re really wired to be monotaskers, meaning that our brains can only focus on one task at a time, says neuropsychologist Cynthia Kubu, PhD.

I'll report back when they do.Cleveland Clinic is a non-profit academic medical center. They have confirmed receiving my message, but haven't responded about the issue yet. (I actually did that just moments after creating the post above). I've already contacted BigTreeTech about this. I only intended the previous comment to be a warning to those who have this modification on their printers. It is obviously such a thing can't be supported here. Even Creality can't support such a modification. This is after all a third party printer with yet another party board in it installed by the end user. It seems to me that the problem rests with BigTreeTech. I don't understand how or why Ultimaker should be responsible for, or try to support, a third party statement, hardware, firmware, or software. There appears to be evidence (from this forum and from other forums) that the BigTreeTech compatibility statement is not true. I have not come across anything that purports the reverse - that Cura is compatible with SKR Mini E3. The BigTreeTech site and the SKR Mini E3 documentation state that the SKR Mini E3 is compatible with Cura. The SKR Mini E3 uses a 32bit ARM Cortex-M3 processor with (it appears) a proprietary bootloader. The standard Creality board uses an 8 bit Arduino clone processor with the stk500v2 bootloader. !!!THIS WILL CAUSE THE PRINTER TO CATCH FIRE IF LEFT IN THIS STATE!!! It didn't take long for the bed or the nozzle to go way out of the safe range. Heaters that are on when this hang triggers, will remain permanently on until something gives or burns. The board hard-hangs so badly, all watchdogs and runaway protections are disabled. I just tested triggering this bug during a print. It *will* destroy the mainboard if left in that state for a long period. My warning to all BTT SKR board owners: Do *not* use Cura with USB hooked up. This is with the BigTreeTech SKR mini e3 v2.0 board. It is only Cura that causes this destructive hard-hang. Other programs can use the USB connection just fine. If Cura isn't loaded, the USB connection works as intended. After some investigation I found the culprit being Cura.Įvery time the USB is hooked up to the computer while Cura is loaded, the board hard-hangs and the stepper motors start emitting that weird siren-noise. I had to buy a new mainboard for the printer. Long story short: The board was destroyed as it was extremely hot to the touch. I turned the printer off and back on again. Went in to check it and found the Ender 3 in a hanged state, emitting that noise from the stepper motor. Gave up at that moment.Ĭoming back home after a few hours, I noticed a weird siren-like noise from my hobby-room. But I saw that the printer wasn't responding any longer. While remote-controlling my computer from elsewhere, I started up Cura and did what I usually do when starting up a print by remote. I left my Ender 3 powered on with the USB attached and didn't think much of it. With the latest Cura (4.6.2 at the time of writing this), this is still a problem.
