EasyThreed X1 All my Mods guide

thingiverse

Hello, this is part of an entire project to turn my cheap Easythreed X1 into a good printer. (This guide might work for other models such as X2, X3 ,X4 ,K1 ,K2 ,K3 ,K4 ,K7) [WIP Album](https://imgur.com/a/YO0nund) It includes custom pieces, remixes from other parts, and the NEMA Brackets from [THIS](https://www.thingiverse.com/thing:4877136/files) thing. The project started by changing the Hotend and Extruder for a Clone V6 Hotend and a Titan Extruder with a 34H motor but turned into a more in depth project that changed practically everything but the frame of the printer. The Easythreed X1 has some major flaws in its design: - Terrible motors with plastic gearboxes and tons of backlash - A direct drive extruder with practically no cooling that tends to overheat - A custom hotend that doesn't allow for any repairs or changes In order to fix some of this issues i started with the Hotend, I found out the easiest upgrade was the V6 Hotend that already had some people making mounts for it so i deceided to try them. They worked but as the project continued i had to customize them a little bit. You can find the original design [HERE](https://www.thingiverse.com/thing:4294577/files) Here's the listing for the V6 i got from [Aliexpress ](https://www.aliexpress.com/item/32837069683.html) make sure you get the 12v version. Then i started looking for a reliable extruder, the Titan extruder is light, cheap and works great. I modeled a way to fix it to the top of the Z Axis. It is the Z_Axis_Titan.3mf file included here. If you get it make sure it includes the motor. [Aliexpress ](https://www.aliexpress.com/item/32969075084.html) The motors were a pain, i tried out a few kinds of them but at the end there is nothing better than the NEMA Motors, at least not for cheap. I got myself a couple of 17hs4023 and one 17hs4401 for the Z axis since it will have to lift more weight. I printed the following parts from [HERE](https://www.thingiverse.com/thing:4877136/files) - x_bracket_nema17_x4.stl - z_bracket_nema17_x4.stl - y_bracket_nema17_x4.stl You'll need to make a couple of holes to fix the Y bracket into the stock base. For all of this to work you'll need more power than the Stock printer has so you'll have to get a new PSU, i got a 12V 5A (60 W) power supply and seems to be working really well, it doesn't draw more than 3.5 amps while heating and no more than 2.7 while printing at 220°C [Aliexpress ](https://www.aliexpress.com/item/32616864643.html) Now for the star of the project i took a model created by Joseph Clarke of the X Carriage and changed it a little bit. There are two versions of this, one for the stock bronze bushings and one for LM6UU linear bearings [Aliexpress ](https://www.aliexpress.com/item/33002162471.html) If you wish to reuse the bronze bushings you'll need to print the BUSHING version (this might not be compatible with NEMA motors) otherwise make sure you print the BEARINGS one. The V6_Mount_Front.stl works for both versions. This new X Carriage uses M3 Allen bolts and nuts of different sizes so....you might need to try a few of them. If your hotend doesn't line up with the corner of the printing bed you can unscrew the Z axis and move it so it homes in the right place (there is an image with the red arrows) **Both versions will need you to change the rotation of the X Axis motor. There are a couple of ways to do it, you could invert a couple of wires in the harness or my recomendation do it via Firmware changing [THIS](https://github.com/josephclarke333/Marlin-EasythreedX1/blob/4da4cb0f58a5176e47e1457d8de5c7f60f84d557/Marlin/Configuration.h#L1333) line to false** Speaking of firmware Joseph Clarke he uploaded a new version of the Marlin firmware for the X1 printer (WATCH OUT only for the X1!!) that also helps with a bunch of the issues i mentioned before. you can find it [HERE](https://github.com/josephclarke333/Marlin-EasythreedX1) along with the guide to upload it to the printer. Other mods i've done to my X1 include: - [Easythreed X Series Thumb Nut Grip Cap](https://www.thingiverse.com/thing:4441034) - [Easythreed X1 X-axis belt tensioner (PLA)](https://www.thingiverse.com/thing:4296030) Thats about it, I'll keep updating this "guide" You can find me and other insterested in this topic on Discord [Invite Link](https://discord.com/invite/jXUXc9jgRM)
