Expanding Storage on Sovol SV06 ACE?

Sovol SV06 ACE
1

Hi everyone!

I keep running out of disk space on my Sovol SV06 Ace, which means I have to delete old files frequently to free up storage.

I recently found the Chopper Resonance Tuner plugin (GitHub link), which looks really useful for motor calibration. However, it has quite a few dependencies and requires a lot of storage space. The documentation states:

Run the macro to iterate through all the chopper options at the previously selected speed, the command will look like this - CHOPPER_TUNE MIN_SPEED=55 MAX_SPEED=55. Check the availability of free space on the host, possible /tmp folder limit on hosts with 1GB of RAM, about ~700MB is required for data. The data collection time will take approximately two hours (depending on kinematics), after completion we open the graph in the same way as the previous time, we get a graph of the form -

Since the SV06 Ace only has 8GB of eMMC, I can see this becoming a problem pretty quickly.

Has anyone found a good solution to expand storage or manage space more efficiently? Any suggestions would be greatly appreciated!

Thanks!

Is it possible to get CRT to use SDA1 for it’s data collection ?

@sovol3d
Do you have you an answer to these questions ?

Right now I have a small adaptation to be able to expand the /tmp folder, what I basically did is mount a USB with the correct format in the /tmp path I had some problems getting Moonraker to work so I had to reinstall it and reconfigure access permissions.
Right now I’m running the chopper scripts, when I have progress on whether my trick works I’ll update here.
I also think that @sovol3d should provide us with an option to extend the system space.

Hi everyone,

If you’re running out of storage space on your Sovol SV06 Ace, especially when using the Chopper Resonance Tuner plugin (which requires ~700MB in /tmp), here’s a simple solution: mounting an external USB or SD card for temporary storage.

Steps to Expand Storage Using a USB Drive or SD Card

1. Identify the Connected Storage Device

Before proceeding, check which storage devices are connected by running:

lsblk

or

fdisk -l

Look for your USB/SD card, which will be something like /dev/sda1 or /dev/mmcblk0p1 (for SD cards).

2. Unmount the Automatically Mounted USB/SD Card

If your printer automatically mounts the USB/SD card, unmount it first:

umount /dev/sda1

Replace /dev/sda1 with the correct device name found in the previous step.

3. Format the USB/SD Card to ext4

Ensure your USB/SD card is formatted with the ext4 file system:

mkfs.ext4 /dev/sda1

:warning: Warning: This will erase all data on the drive!

4. Get the UUID of Your Formatted USB/SD

Find the UUID of your device using:

blkid

You’ll see an output like this:

/dev/sda1: UUID="e71df4cb-218c-db01-200d-f4cb218cdb01" TYPE="ext4"

Copy the UUID for the next step.

5. Create a New Mount Directory

Create a dedicated folder for the temporary storage:

mkdir /mnt/mytmp

Set the correct ownership so the sovol user can write to it:

chown sovol:sovol /mnt/mytmp

6. Bind the USB/SD Card to /tmp Using fstab

Edit /etc/fstab and add the following lines:

UUID=e71df4cb-218c-db01-200d-f4cb218cdb01 /mnt/mytmp ext4 noatime 0 0  
/mnt/mytmp /tmp none bind 0 0

Replace e71df4cb-218c-db01-200d-f4cb218cdb01 with your actual UUID.

7. Apply the Changes and Mount the Drive

Run the following command to apply the new mount settings:

mount -a

Now, all temporary files will be stored on the USB/SD card instead of the internal eMMC storage.

Conclusion

This method helps free up internal storage and prevents /tmp from filling up when running Chopper Resonance Tuner or other storage-heavy processes.

Hope this helps! Let me know if you have any questions. :blush:
