So like the title says I’m interested in any pros and cons of setting $1=255. The reason I ask is because a little while back I was being more aggressive with a 1/4" bit and I think it dragged the Z down. If I recall correctly I was doing a 4mm pass depth at 70inch/min or so. All I know for sure was I ruined two pieces of wood in one session because the bit sloped down on a profile cut. After stopping the machine and moving the Z up, the bit seemed to still be tight in the collet.
So here’s what I got for possible pros and cons.
Pros
A bit is less likely to drag the Z down if that’s what happened.
Cons
Possibly reduced lifespan of motor?
If anyone has pros or cons to setting the motors to always energized, or runs their machine with them always energized I would be interested in hearing what you have to say.
@_Michael I’ll be interested in any replies, Michael. FWIW, I question whether your Pro is accurate. It may be, but I doubt it. As for your Con, you are right and I’ve read this somewhere in the forum. The motors will run warmer since they never power off and that could/will lead t reduced lifespan.
@_Michael I can’t comment on your Pro. Your Con has been discussed here before and you are right.
Another pro comes when using the laser. I found that leaving the motors energized resulted in more accurate burns, particularly in corners when the Mill is changing direction. The advice that I received from the LAHobby guy was that the laser was turning off prematurely because the motors powered down coming into the corner. I could only prove that by entering $1=255. Sure enough, my issue was solved. I don’t pretend to fully understand it, but worked.
. I will be leaving $1 at it’s default value. Thanks for the response.
