Pocket toolpath issues

[alt]

Hello everyone,

I had/have a very strange issue today with my AR8 Pro. 

I started with a very simple project and ran a profile toolpath to cut out the shape with tabs. Next toolpath was started using the same bit, this time a pocket toolpath. The pocket toolpath then ran and cut much deeper than I had selected. Thinking it was a mistake I made in Aspire, I went back to the computer and rechecked the toolpaths and went back to the machine to go again. Same results. So here is a list of what I've tried, to no avail:


-Aspire file is set correctly with the Job Size. Material is .125 MDF
- Z Zero position is set to Machine bed

- Profile toolpath was set using a 1/8in EM to a depth of .127 and ran successfully to the correct depth. 
- Pocket toolpath was set using a 1/8in EM to a depth of .015 and it plunged to a depth of .1

- Using the Puck, I zeroed the Z axis. Same issue
- Using a piece of paper, I zeroed the Z axis. Same issue.

- Pocket toolpath was recalculated in Aspire to a depth of .0015, .5, and a few others which all resulted in the same depth of .1


Machine was powered off, turned on, Home'd all axis, re-set the Z axis using the puck and nothing seems to change the results. Any suggestions would be appreciated.

Thanks,

Ryan

Ryan, can you post both of your mmg files? or send them to me so I can do some checking?
Thanks,

One other piece of information. In Aspire, the simulation does change to display my change in depth of the pocket toolpath depth. Thanks for taking a look Michael

Ryan,
A few things,
First, I see that your screen shot, that you posted, shows your cut depth at 0.0015 but you say you want a pocket of 0.015...
Also, in the mmg file, line 4 shows the Z depth to be 0.11. ( 2.794 mm )
Did you recalculate all tool paths ??
The machine will cut to the depth in the G Code.
I would try recalculating or make a new file an see what the Z depth is in the new mmg files.
