I am carving a deer head on a piece of rough cherry. I want to pocket the background- so the deer head is raised and remains with a rough surface.
I contoured the deer head with a V-bit (60). Looks really good so far.
I used a 1 1/4” surfacing bit to pocket out the background. Since the board is not even, I wanted to be cautious- I did a “skim” toolpath where I went down to .5 mm going down only .1 mm per pass.
After this I did a pocket (start at 0) down to 4 mm. All that worked and the big surfacing bit didn’t get grounded on any uneven sections.
I then did a pocket REST operation with the #201 bit. Starting at 0 and also going to 4mm. The 201 hit the spots the larger surfacing bit could not reach.
My issue is the 201 carved everything about .25mm lower than the original pocket.
In my mind 4mm depth is 4mm - the uneven surface should not impact depth (I didn’t reset zero in between passes). Why would the REST operation go deeper?
Some surfacing bits are not compatible with the BitSetter. I have a Whiteside 6210 and that bit has a hole in the center big enough that it goes over the BitSetter. So when using my Whiteside I do not use the BitSetter and turn it off in CM.
Take a look at your bit to see if it will hit the BitSetter Button and if when hitting the BitSetter button it is not hitting something else when plunging.
It must’ve been due to the surfacing bit, not registering correctly. I did not have a picture of the issue and I’ve already corrected it.
On the same board in some unused space, I tried to re-create a problem and the problem did not reoccur. The only logical explanation is that the servicing bid did not register properly with Bit setter
I will keep a close eye on this bit in the future.
