karl_ranseier In my opinion M9999 should be allowed espacially during fatal state. It might make sense to forbid it during printing.edit: and by the way, a category for DEV2 in this forum would be nice.
Repetier Actually I think most of the m codes should be allowed. Why block M105 for example or all the other setting changing m codes. So now I have inverted it and allw nearly all mcodes except a few.Not sure about the dev2 special channel. Will discuss this.
