G-Code Emulator

I'm looking for a G-Code emulator.
I need to analyze and modify the script in Simpify3D.

I'm trying to install my PrintZ and need to avoid the binder clamps suggested by PrintZ manufacturer
I had installed them but the nozzles run into the right clamp.

Attachment 7265.

Thanks

use thin strips of kapton or pet tape at the corners to hold the bed in place. Bulldog clips just don't really work.

I've had an aluminium bed attached to my original non-flat bed with the same tape for 8 months or so.
Definitely the best way to do it.
