Cutting 1" Ultraboard CNC router

Morning,

I haven't been trained yet with the router in detail but I've been trying to do some test cuts and I am having issues. I am trying to cut 1" ultra board on enroute Multicam3000. Can anyone recommend the settings to route in offset section and keypad? Not sure what I'm doing wrong but it does multiple cuts on the same letter about 5-6 and it's only set to 2 in enroute.

Bit: 1/4" end mill
Current settings: 1" depth
Surface: 0"
Final Depth: 1"
Passes: 2"
Max per pass: 0.765"
Actual pass 0.50"
Final pass: 0"
Width of cut: 0"
Number of steps: 1
Max step: 0.2250
Feed rate: 150
final pass speed: 0
Plunge rate: 55
Dwell: 0
Spindle: 18000
Conventional

First of all, if this is the ultrafoam with a metal face, I found my results greatly improved if I cut it with a standard aluminum bit first, just through the aluminum, then came back with the foam bit. It can also be done upside down, with the last cut being the metal bit. I suppose first you really need to wrap your head around enroute properly, before worrying about quality of cut.


Bit: 1/4" end mill
Current settings: 1" depth
Surface: 0"
Final Depth: 1" (I don't use enroute, it may be very clever, but my router would consider this -1" and if I told it 1", it would run above the material. Seems like this is correct)
Passes: 2" (Is this an inch unit or a number of passes?)
Max per pass: 0.765"
Actual pass 0.50"
Final pass: 0"
Width of cut: 0"
Number of steps: 1
Max step: 0.2250 (this will make it a 5 pass cut I think)
Feed rate: 150
final pass speed: 0 (this will cause the machine to stop before the end of the program, or throw an error)
Plunge rate: 55 (this seems too fast, I tend to plunge at 10, not at issue though)
Dwell: 0
Spindle: 18000

I also have a Multicam 3000. Here are my settings for cutting brushed metal face on foam


68 speed, 60 plunge, 14000 spindle, climb cut, 2 pass
 
I am looking for settings for 1" foam with PVC face originally in this thread but if you have 1/2" brushed metal face I'll go ahead and try those.
