I recently purchased the new SV06 ACE Plus and everything is going swimmingly until I noticed orca could no longer connect to the printers IP address, tried the browser and no luck. the error given is ERR_CONNECTION_REFUSED which isn’t very helpful. Any troubleshooting tips?
How are you connecting, straight to Router, Hub, Raspberry Pi, Sovols Klipper or did you install full Klipper..??
I made no modification to the base printer, connected it to my wifi router and connected it to orca slicer via its ip address. I also connected it to the obico app and that works funny enough still. I even followed these instructions from a similar thread and found that my laptop was still able to communicate with the printer.

In general, this points to a networking problem. The printer might not be on the network, or your machine might not be on the network.
To diagnose, you can try using the “ping” command with the ip address show in the dialog box.
- open a Terminal (Linux, macOS) or a powershell (Windows)
- on the command line, you can enter commands.
- try the command ‘ping 192.168.0.27’ (do not enter the quotes). Ignore the port number.
- if the command is successful, it will tell you that it got a reply (well, it will try more than one time, so it will be several replies.
- if it can NOT connect to the printer, it will say “timed out” or similar.
- if the command keeps on trying, stop it with Ctrl-C (hold down the Ctrl key, then press the ‘C’ key, release both keys."
I feel that a factory reset might work cause it seems just like a random persistent error rather then something actually broken, Ive power cycled my printer, my laptop, my wifi router, and reconnected the printer to the router also.
Check Orca slicer to see if you chose the right ACE printer.
When you add the IP it renames the ACE to ACE Copy unless you name it something else.
I named mine ACE WIFI. The default ACE has no internet connection.
Ive had it set to the right printer, the - Copy version
If Obico connects, I would verify that the Obico IP & Orca’s IP are the same.
On a side note, check the Firewall logs if you run one to make sure Orca is not being blocked.
Also Orca had an update yesterday to 2.3.0, try updating & see if that changes anything.
it was trying to access .187 when it was supposed to be .186 >.>

For what it’s worth, my SV06 Ace appears to change its IP address (last 3 digits) all by itself. I just enter the changed digits in Orca and it then works well. Am connecting via Wi-Fi.
FWIW, the most common way for network device to get an IP address is via DHCP, the device gets a “lease” on an IP address from the DHCP server (normally your router or Wi-Fi access point) for a “lease time”. The DHCP server keeps a list of addresses it has leased out, and the time they have been leased out. When the lease time is only 50 % left, the device will send a query to the DHCP server to say that it will want to renew the lease. Every time you turn on your printer it will ask for an ip address, if the lease time hasn’t run out or if the previously allocated address is available the DHCP server will just give the same address as the previous time. For a network device which is on most of the time this works out, it will seem that it always have the same address. If the “pool” of ip addresses is limited, or if the device is on only very rarely, it will get a new ip address.
Ways to solve:
- increase the number of ip addresses in the DHCP pool
- increase the lease time (if you have fewer pool addresses than network devices in use this will not help)
Another option (the best for me):
- In your router, assign a static IP address at your printer by MAC address.
It will do this sometimes after a power outage.
