Hopefully this paints a timeline for you which is helpful?
Also I know that sled was centered then to my center support piece of frame on groundcontrol, 99% sure of that.
Ok, so you performed a calibration and set up using ground control but never really used it. But at hte time, your sled was centered to your workspace.
Yeah I can confirm has to be, as those test cuts from groundontrol calibration, they are within a 1/4 inch of one another from the edge each respective side. Which me measuring and input, should of then dialed in the machine. No way off that much like center is now in Webcontrol. Hope this helps as well 
When you transitioned to webcontrol, you had to set up webcontrol on a raspberry PI. Did you use the pre-built image available on the webcontrol github page?
Yes Jon, you got it. My test cuts are still on the boardā¦the left is exactly 10 inches from the edge of workpiece, the right is 10 1/4 exactly. probably best you could do at the time for first calibrationā¦they put those numbers into ground control, it should of adjusted everything as center looked perfect then.
So with the piā¦I used the prebuilt image firstā¦it worked as in you could connect and computer moved the maslow when connected IP addresses. The issue was it was only a service, you only saw the code on the screen. This is when dlang or Orob told me āhey, you need to build the image yourself on Raspbian basically, and they thought it was a lite version on the prebuiltā Not exacly in those words, but that was the message
I already had raspbian on a card (I think), it was newer, so downloaded Webcontrol and off to the races. I did make sure Raspbian was the latest, I checked for update and upgrade of course prior to the Webcontrol download.
ok, so you first tried the prebuilt PI image but then ended up building it manualy? Which meant you installed webcontrol manualy as well. Correct?
let me clarify, Orob or dlang also said the drivers for the display were not in the life version, so if want to do what you are trying to do, you need that full version of raspbian, load the Webcontrol yourself. Why I went that routeā¦
yes!! you got it 
I manually got Webcontrol on the version using in the Pi
ok, so far so good.
After getting WebControl to start, what was the next thing you did?
My son then went (with help from Orob I believe and others) to add code to start Webcontrol as a serviceā¦then added code to run Chromium on startup, set to the IP address to log into ground controlā¦then put it in Kiosk mode so the screen above the frame would always go to Webcontrol when the pi was booted.
changed post to belowā¦
wait wait backup!!! sorry
Hold on. we need to pasue here
deleting last post for nowā¦one sec
Hold on a sec, this is where i think things went bad
After you installed webcontrol and your son set it up as a service, auto launch chromium and enabled kiosk mode. You would of had to configure webcontrol with settings. Youeither need to enter them manualy (from scratch as a new set-up) or you needed to import your old configuration file from ground control. What did you do?
ok sorry, Next step after getting the monitor to display Webcontrol and Pi to run as a service. I wanted to calibrate again, so I knew about Holey. My mom was here to help me read the measurments (they were far apart, and I could not see if holding the tape on the mark and read the tape at same time). I update the firmware, then got holeyā¦it loaded and the button was ungrayed. We did the holey test, but did NOT know the marks were off center. Only today I noticed those center test plunges were off to the left. once done, I stopped for that night assuming all was calibrated. I went to make a square, it was good for a put then got destroyed. The cuts way too deep. Ran another one, same thingā¦cuts to deep and part destroyed.
Thats when realized the Z has to be wrong. Orob dlang and all you helped me realize the settings were off for encoder, and for the pitch as I entered the meticulous X pitch of 24. i fixed that, you all explained pitch so I now know the screw itself was the sameā¦only what did have to change was the encoder Z info. I used 600ā¦David agreed with the calculation.
