Welcome to the SeeMeCNC Community

Hi. I'm running Repetier-Host 1.6.2 under Linux -- supposedly the most recent version. No matter what I do, I cannot see the debug controls that are supposed to be under the manual controls (please see attached photo). I want to use "Dry Run" mode -- but need those controls to do it, or alternately need to know the script/codes to send to manually trigger this mode. Odd though that the buttons are missing. Any ideas? Thanks.

You're not running a SeeMe or Delta configuration, so the readers of this forum are going to be of limited help to you. Many of them aren't using Repetier Host anymore and most of them aren't using Linux.

One possibility that springs to mind is that you may not be using Repetier firmware at all, and Repetier may not have put any effort into supporting other firmware, other than disabling things that don't match up.

As for G/M-code commands, look at FIRMWARE documentation for that, not the Host.

I found it. The controls only appear when Repetier-Host is in direct connection (e.g. serial) mode. They are not present when connected to Repetier-Server. Thanks!
