and it works in univerdal gcode sender

Is this a Carvey/ Inventables machine?

its a homemade cnc based off this

Is it possible you left it connected in UGS and thus CP can’t access the port? It looks like the checkbox is checked, but that 99 in your buffer progress bar shows that it’s not processing any commands from CP at all. You sure your board sends back newlines and OKs like all Grbl devices cuz that’s how CP knows a line is processed.

wahst exaxtly is ugs and cp? sorry new to this

You mentioned it works in Universal gcode Sender (that’s what John means with UGS) and he suspects the Port could still be blocked by UGS so your Connection attempt fails…


yea just restarted my computer and just opened chilipepr and this it what i got

and has anyone accually used a cnc v3 with chilipepr?

Ok, so Chilipeppr doesn’t connect, does UGS still do so? If so then maybe it’s retaining the port?

yea i think it is doing that how would i fix that?

To start, it might be a good idea to disconnect in UGS and close that program, then try again in Chili. Restart your computer if you need to, and try again.

This doesn’t really help us with anything.

Formula for polite and efficient interaction with support community:
-Please speak in complete sentences with proper spelling, grammar and punctuation. Fragments and run-ons are not pleasant nor easy to read. We understand that many of our users are not native English speakers, and are more than accommodating, but some effort should be made from everyone please.
-Explain what is happening. A picture tells a thousand words, but we need at least a few words explaining the context: what did you do, what the issue is, what the machine is or is not doing, and so on. Also please include pictures of the full screen, and then use words to tell us where to focus our attention, as described above.

Just 2 steps to make the lives of the people helping easier, and to improve your odds of getting help.
Thank you,
