Help with error 9 and basic Z issues - tripping limit switch

Hi CAM experts.
After a year not using my school's WorkBee 1010 with xPRO, plus having the computer go down, I'm trying to restore all of the settings. I'm currently getting the error: 9 - G-code locked out during alarm or jog state (X19.05 Y19.05 Z29.11475). I thought all of my settings were how I had them last year. However, right before plunging down, Z instead goes up instead, tripping the limit switch. Any help on troubleshooting this would be GREATLY appreciated.

Note: I am using the older post processor from this site: swarfer/GRBL-Post-Processor.

Here are my Grbl settings:
$0 - 10
$1 - 255
$3 - invert x and y and z
$4 - enable
$5 - disable
$6 - disable
$10 - 1
$11 - 0.02
$12 - 0.002
$13 - disable
$20 - disable
$21 - enable
$22 - enable
$23 - 3
$24 - 100
$25 - 1000
$26 - 250
$27 - 3
$30 - 1000
$31 - 0
$32 - disable
$100 - 199.1
$101 - 199.1
$102 - 199.1
$110 - 2500
$111 - 2500
$112 - 2500
$120 - 150
$121 - 150
$122 - 150
$130 - 824
$131 - 780

THANK YOU!

 

Thanks for replying Giarc,
Good question - yes, when I home the machine and set the work coords, everything is fine according to my setup. I'm using the OpenBuilds Control software.

 

Thanks David the swarfer,
Yes, I downloaded the Virtual COM port drivers last week, and I had even seen your newer post processor. I couldn't tell if this was the problem or not, so I tried going back to what was working before (switching back to the older version). I didn't try milling a different file yet; that's a good idea. I'll try to do this tonight.
Thanks for the tips.

So I finally had a little time to play with it more. I just printed the default example and that worked. So, the problem lies in my CAM setup from Fusion 360, I think. It's been awhile since I messed with that too. They've changed the way some of that looks in the past year. Thanks again for your help.
