I have ruined a couple of carves while changing the tool because my wrench slips on the router nut. The motor moves, i.e., my start point moved! Should I be able to move the motor during a tool change?

It is possible.

Make sure $1=255 and that the XController idle reduction switch is set to OFF.  
This ensures that the motors resist any shifting at full force.

I printed this with my 3D printer and it makes changing bits so much easier, and I can do it with less force:

If you having home switches and you ever move your machine manually for whatever reason, just home it again and it’ll find the last home position you used.

If you don’t have homing switches, one trick I use is to take the machine to the extreme left and forward position, and mark it. I used a 1/32 bit and made a shallow hole in the waste board. Now when the machine moves all I have to do is take it to those limits and in theory be where I was at the start. Has worked for me so far. I have tried to use the buttons in Easle to lock the motors but they seem to do nothing at all for either of my machines.

I do have home switches and what you suggest makes sense. A couple of times I had a start position in the middle of the workpiece instead of the 0,0 position.

TroyWright, nice idea. i do have homing switches, though.

Thanks, Todd1. When I get a 3D printer (soon I hope), I will try the wrench for Dewalt

Thanks, HaldorLonningdal. I will check those settings.
