I am having an issue with my router which is only 2 years old with part-time use. I now realize this issue was there from day one.
I would often being cutting too deep or too high by up to .040", and thought it was not Z zeroing after restart.
Then I discovered but checking my tool measurement values that I got skewed values if I re-measured after the machine had been turned off.
If I re-measure during operation the values repeat accurately within a few ten thousands and often exactly the same 5 times over.
If I shut down or E-stop the values will be off by up to .040" in either direction, all tools not just one specific one.
Tech support said it might be,
#1 bad surface on tool measure-it's perfect.
#2 dirty power coming in-checked in diagnostics not that either
#3 Not shutting down programs before turning PC off- I always do,even E-stop the machine before shut-down.
Any insights appreciated. I will follow up with ShopSabre but they were moving when I contacted them so they were a busy bunch no doubt.
