Sampo Solo: free DNC program transfer for home and hobby CNC machines. Free

What it is

Sampo Solo is the standalone little sibling of Sampo: one machine, one folder of programs, no cloud and no account. Run it on the PC beside your control; a local browser page drives send and receive over the RS232 cable, or runs a read-only FTP server the control pulls from. Your programs stay ordinary files in a folder you own — revision history is your filesystem.

Licensing

Free for home and hobby use, forever — nothing is feature-gated. A business using Sampo Solo for commercial work needs a one-time per-shop license: email us.

FAQ

How do I send a G-code program to my CNC machine from a PC?

Run Sampo Solo on the PC beside the control, drop your programs in its programs folder, and open the local page it serves. Pick a program and hit Send; it goes out over the RS232 cable. Receive captures a program off the control into the same folder.

What serial settings does a Fanuc control use for RS232 program transfer?

The classic Fanuc punch settings are 4800 baud, 7 data bits, even parity, 2 stop bits, XON/XOFF flow control. Sampo Solo's setup offers exactly those as its defaults; confirm against your control's parameters before the first transfer.

Is Sampo Solo really free?

Yes — free for home and hobby use, forever, with nothing feature-gated. A business using Sampo Solo for commercial work needs a one-time per-shop license.
