I forgot a key feature in this overview: preview. It is generated in one place only, and language independent - no 'preview interpreter needed' as we have it now in gcodemodule.cc used in Axis and gremlin. The VPT machine will have two executing modes: 'preview' (does not wiggle HAL pins, motions complete immediately) and 'for real' (wiggles HAL pins which move the machine, motion complete normally). The line, arc, probe etc motion primitves are tapped near queue #2 and fed to the UI; the same interface is used for preview and progress report, resulting in less chance of preview and progress display falling apart optically. So the preview flow could be: - load program: frontend loads file/gets MDI command string - parses it, executes control structs and generates a block list - VPT machine gets the blocks list, runs through it in preview mode, generating the preview command or display list *) - execute program: VPT machine switches to 'for real' mode, feedback from the same interface is now progress report - Michael *) conceptually we set overrides to '1 Mio % or so' ;) ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
