Here are the reasons NOT to purchase the Twotrees SK1 printer:

Extruder with built in filament detector, when it detects a filament break it tries to unload what is left jamming the extruder gears resulting is disassembly of the print head to get to the extruder gears. Or with firmware update it lets you insert new filament then tries to grab the filament as it feeds the rest of the old filament, sometimes it works.

Nozzle + Heat sink are clones of another printer with a modification to the heatsink body, at this time you cannot buy one, over a month waiting on a replacement due to filament plug.

Z axes motors internally support the Z axes bed weight, lack of bearing load carriers shortens the motors life considerably.

Heat bed is a DC (24 volt) model that takes 4 minutes to heat up with a top temperature of 105°C, it is unique, there are no 'third party' AC (110 volt) heat pads to fix this.

At this time there is no documentation so it is impossible to determine if there is a thermistor for the chamber, without a thermistor there is no means to regulate the chamber temperature, printing ABS or other high temperature filaments becomes a joke.

Dealing with Twotrees Customer Support: Two weeks of emails, images, videos and still waiting on a tracking number for a $10 nozzle, meanwhile the printer is collecting dust.

Noise: I lost some hearing in Vietnam so load printers generally don't bother me, this printer with three always on high RPM fans is insane, to Twotrees credit they used a power supply with a 60mm fan that only comes on with heat but the other three fans are insane whine level!

The Display, what can I say about a Nexton serial display besides it sucks, the machines controller lacks a HDMI port so you can't add a cheap Klipper Screen, you have to purchase a stand-alone computer with a HDMI display to add a decent display that doesn't lockup interminably .

On the subject of the machine’s controller, the 'disk' is a 8GB emmc device with 953.5MB of memory, 35% used at idle. The Klipper Load hits 113% during bed mesh. A 32GB emmc module is $4~$12 AliExpress. The OS is Debian Buster which was replace with Bullseye in 2021 and currently at Bookworm in 2023, there is no upgrade for the OS or Klipper as shipped, all update managers are disabled.

Customer Support would not give out the root password, I found it at MakerBase as their default User/Password for any controller they sell. They (Customer Support) did threaten me for posting the user/password then they apologized, said I miss-understood what they said.

If you need to burn $500~$650 but this printer!
