Mercury ZeroG (Ender 5 MOD) Build Info/Klipper/Slicer Profiles

Updated 10/09/23 with new build infomation to suit the 1.1.6 parts we fitted.

The Mercury ZeroG is a Voron inspired core xy modification/upgrade for Creality’s Ender 5 3D Printer. There are two parts to the Zero G project, the Mercury1 core XY system, and the Hydra bed system. Here we aren’t going to document on how to preform the upgrade, but simply list what we used, our Klipper config and slicer profiles to help others doing this mod. We will also list useful links to get you through.

The Mercury1 is completely open source and still a growing project with a large selection of mods to suit you and your needs. Soon they will be releasing a full custom frame build which will make the build area enclosed. Mods we’ve done from the standard build on ours is the E34M1 to change from the eva 2 to eva 3 toolhead. The electronics enclosure by Turtlecrawler. We have also used a custom screen mount to use the TFT 35 SPI by Bigtreetech. Designed mounts for our 5015 cooling fans in the electronic enclosure. And a din mount to suit the CPAP/ws7040 driver board and blower fan.

Special thanks to the ZeroG community discord & Klipper subreddit for their help. I thoroughly enjoyed doing this build!

Mention list:

Parts we can supply list & used:

These are the parts we decided to use. The great thing about open source 3d printers is the choice is yours and what works best for you.

Klipper Config:

Please note, this klipper config is made to use with the BIGTREETECH Manta m8p v1.1 and they other parts listed above. Using a different board will completely change everything. Even with all the exact same parts you will have to pay attention to your end stop locations & the mcu serial. You will still have to tune your esteps and PID tune your heated bed and hotend. Ive tuned this to a reasonably fast speed. Though it could go faster, I found these speeds to be reliable.

MCU serial can be found by following the directions found on the klipper docs.

Our config certain files included, namely for input shaper, the obiter filament sensor and the test speed macro by ellis3dp.

To PID tune your hotend in klipper use the following code pasted into your console via mainsail.

PID_CALIBRATE HEATER=extruder TARGET=215

To PID tune your heated bed in klipper use the following code pasted into your mainsail console.

PID_CALIBRATE HEATER=heater_bed TARGET=60

Guide for tuning your esteps has been listed above. TeachingTeach and Ellis3dp touch on the subject.

The below slicer settings are far from the fastest we can push our Mercury1 but a great starting point.
