WinCNC postprocessor outputting multiple commands per line - not validating when set to run

[Alobdell89]

Hi folks - hope I can get this cleared up fast. Picked up some much needed freelance design work and now have the opportunity to save the day if I can get these parts cutting tomorrow morning on a shop's Techno Titan running WinCNC. 

When I load the toolpath into WinCNC, it errors out saying 'multiple commands'

I found mention of this error in relation to WinCNC not processing arcs across the Z-plane and followed the directions in this forum post to no avail

What does seem promising and likely are reports that WinCNC requires every G-code command to be on a separate line and the 5th line of Fusion's code combines a G53 and G00 to a single line, unlike the working code posted by the shop's regular tech using Rhinocam (attached both)

Now that I'm home, I found I can remove that specific instance of combined G-commands on my 5th line by configuring the post-processor in the final screen before .tap file output (the menu on the right side for post-properties under 'Safe retracts and home positioning' and configuring the option to retract to Clearance Height rather than G53.

If it was my shop, I wouldn't have left before I figured it out and in the best case scenario now, that one option produces the only instance of multiple G-commands on a single line and everything is solved when I walk in tomorrow. 

However, it seems that if it was that easy to select a standard option for safe CNC operation that results in a critical failure then I would have no assurance that it wouldn't write multiple G-commands to a single line for another reason and I'd have no clue how to diagnose it.

Any advice on recovering from the 'multiple commands' invalidation is welcomed, but I feel like I'm very much looking for an option or modification that forces Fusion to only output a single G-command per line.

Any insight on workarounds or gcode verifiers is also welcomed, so I can check the code at home before showing up tomorrow morning. I keep seeing references to a defunct software called 'VisualCNC' and it looks scarce.

cheers!
