I am running the 1F Elite Foreman with PWNcnc 80mm ATC spindle and the 1F braking z motor. Not sure if anyone else experiences this, but I thought I would post along with my ‘fix’ to prevent it causing issues in a carve.
I often hit the E-stop button if I know the machine is going to be inactive for a period of time while I’m in the shop… but not for so long that I want to shut it all down. I do this mainly because I don’t want to listen to the ‘whining’ noises that come from the steppers. They’re like a dog whistle to me… LOL.
However, when I do so, the Z axis drops about 1/4" before braking. Not a big deal, except I learned the hard way that if you reset the E-stop and just continue carving, your zeroing is now off by that 1/4". The way to correct it is simply to re-home the machine after resetting the e-stop. This is easy to remember when turning the machine on, because it makes you do it. But it is VERY easy to forget if you are resetting the E-stop after having activated it while the machine remained on the whole time.
My solution was to go into the homing screen on the F1 setup tab, and there is a box you can tick for ‘request home after E-stop press’. Check that and it will tell you to rehome just like when you first turn on the machine.
Hope this helps someone.
