Re: [Emc-users] F-Engrave and LinuxCNC scripting
One option would be to generate one big G-code file, with the appropriate M-CODE to break it up, and an operator's comment to let you know which section is coming up next. 1. The operator would get a message like: (Prepare to carve Billy G's name) 2. Put the part in the vise and hit run. 3. The operator get's a message: (Prepare to carve Billy G's nickname) 4. Flip the blank and hit run. 5. The operator get's a message: (Prepare to carve Terry M's name) and so on. It would probably really mess up your back plot, but you could have your program generate each individual section with indexed names, like: Names001.ngc Names002.ngc ETC. So you could preview what F-Engrave did, but also have your program generate: Names-ALL.ngc for the actual cutting once you are satisfied with the g-code.

Re: [Emc-users] F-Engrave and LinuxCNC scripting
If you wanted totally automated, you could use linuxcncrsh. Ngcgui or pyngcgui sound like they might be useful for this too. Otherwise, overwriting the single file (or copying over) doesn't sound like that bad of an idea. -- Ralph From: andy pugh [bodge...@gmail.com] Sent: Wednesday, February 23, 2022 2:33 PM To: Enhanced Machine Controller (EMC) Subject: Re: [Emc-users] F-Engrave and LinuxCNC scripting CAUTION: This email originated from outside the Walla Walla University email system.

Re: [Emc-users] F-Engrave and LinuxCNC scripting
Are you going to engrave one part at a time, or hold them in some array fixture? Either way, I would probably have the python script add preamble and postamble to initialize everything, and in the second case, add indexing logic to step from part to part in the array. G-code variables and looping make this easy enough, or the python can do it all and just generate G0 and G1 moves for the entire array. -- Ralph From: andy pugh [bodge...@gmail.com] Sent: Wednesday, February 23, 2022 8:20 AM To: Enhanced Machine Controller (EMC) Subject: [Emc-users] F-Engrave and LinuxCNC scripting CAUTION: This email originated from outside the Walla Walla University email system.
