Playing with CNCjs and can’t seem to get zeroing out to work…anyone else have this? I get the pen (don’t have a router yet) to the location and they try to zero out and I see this in the console.

echo:Unknown command: “G10 L20 P1 Y0”


I’m using a rambo 1.3 with the latest firmware from V1

Looks like I just need to use the console and use the G92 command to do what I need.

Hi someone wants to help me install cncjs on a pi 3b. At the moment I have tried it 6 times but I get error messages all the time.

It has since become a mix of different forms. I reinstall pi and hope to get help from you.
Thank you

I install pi light and can go to my mac via the terminal. the wifi connection works well.
here it goes wrong somewhere
