I am new to the SHO 5, so forgive me and point me the right place if i missed something.
I was able to pick up a new used SHO 5 and been having fun, until…
I was doing some work on acrylic etching some lines for a special ruler and noticed a difference from left to right. So i ran a flat larger piece over the slats and noticed some jumping and grabbing. NO worries, i live in Oregon (west side) and figured that maybe a bit of moisture, it was not leveled, etc. I ran CutRocket’s job using the McFly cutter for the SHO 5 4x4
The issue is that I was able to see banding on the waste board. ( I had to take off .45MM due to a low point in the middle of the surface) - Just looking for verification of the fix. I need to put my dial gauge on the waste board, find the measurements and start shimming.
This usually indicates the router/spindle needs to be trammed. Since it moves across right to left you likely just need to adjust the router mount with shims… You could do that but instead of rerunning the surfacing just take an orbital sander and remove the marks. If the marks from from front to back then the router mount needs to to be adjusted with eccentrics right/left. These marks are caused because the router bit is not not square to the spoilboard. So either the front or back of the bit is higher/lower and makes tiny ridges.
Agree with the need for a quick tram. In my case I used a piece of flat float glass, shimmed it on the spoil board for flatness and then adjusted the spindle mount using the SST mini tramming tool (not required, other approaches work well too). For what it’s worth - my 4x2 trammed out nicely with only very small adjustments needed in both directions.
I will try and make this clear as possible.
Was able to make an adapter for my digital dial gauge to hook up to my router.
Got my shims tonight so i got a piece of glass i had and leveled it.
Black / yellow / Blue spots all reading 0.00.
I then placed my router in the middle and swung it to the grey location and zeroed it - verified it held zero.
Then swung it around to the yellow spot and it read off +.67MM
I then dragged my cnc with my Gauge still on the right side over so the gauge was over the grey spot and it read +.60MM
This (to me) tells me that the glass is not level by .07mm, but the head is not level by .60MM with the bottom being tilted to the right
The issue is, if i am correct in the measurements ( repeated several times to verify numbers), then the grooves on the waster board are showing a different story.
When using the McFly bit i noticed that i had grooves side to side and front to back…
I am just focusing on the front to back grooves right now, and they are showing a high left side with a fall going down to the right, then an abrupt high again on the right, with a difference of .02MM
