Optimizing the SV06 Plus ACE Print Preparation Routine

My SV06 Plus ACE is my first 3D printer, and I don’t regret buying it. The fully open system allows me to adjust and tune almost everything.

I’m still learning, but I find the default print preparation routine too conservative. The full bed leveling also wastes a lot of time. With the help of AI, I tried several times to modify the G-code, and now I’ve found a relatively fast print preparation routine.

The main changes are:

Full bed leveling → Print area leveling

Instead of probing the entire bed, it only probes the area where the print will be located.

Preheating strategy

Heat the bed to printing temperature – 20°C

Heat the nozzle to 150°C

Then home the printer and start Z calibration and nozzle cleaning, which avoids long waiting times for heating and cooling.

During this stage, the bed continues heating to the final temperature.

The nozzle then cools down to 130°C for local calibration.

Finally, the nozzle heats up to the target printing temperature and printing begins.

If you want to be more aggressive, you can even keep the nozzle at 130°C and skip the cooling step entirely.

However, cooling the nozzle from 150 °C to 130 °C only takes a very short time. I’ve printed several times with PETG using this setup and it feels almost perfect so far, though I’ll continue to observe and test it.

Hello,

It might be useful to explain how to replace the default print settings with your own, as well as the new gcode.

This will help those who wish to do the same.

I connect to the printer via Wi-Fi and modify the printer.cfg and macro.cfg files.

If needed, I can provide the specific code, but this is my first printer and I also modified the G-code with the help of AI, so I cannot guarantee it is correct. I recommend following the idea I provided and modifying your own code, which would be safer.

The main time savings come from three parts:

Continuing to heat the bed by an additional 20°C during the nozzle wiping and leveling process.

Reducing the waiting time when the nozzle cools down from the printing temperature (over 200°C) to 130°C.
