What is the best power management setting for the TinyG to keep the z axis from drifting down? I am using $pm=2 and $mt=3600
Perhaps I need to turn up the current on he z-axis?
@Colin_Kaminski should just be $1pm=2
That’s what I thought. I lost about .2 mm per pass till I was 10mm lower. I was not in the room so I don’t know what happened. It was plunging deeper than I had intended and I was shaking up the machine (looking at the cut). While it was dropping it was ramping a 1/4" cutter to 3/4" depth over 5 inches. I was expecting it to deck it out first. It vibrated some fasteners lose as well but the screw stayed tight. I went through all the settings tonight and found a bunch of problems. Things I thought I had right but weren’t set the way I thought. The Chillipeppr settings app was not working correctly. I went in and set everything by hand. I’ll try to do a $$ dump and post it later. I still have not tweaked my jerk settings.
@Colin_Kaminski sounds like you are on the right path. Not sure the material you are working with, but a 1/4" end mill drove 3/4" over 5" may be very aggressive. She could easily push out at that ramp speed.
The part I am prototyping will be made from maple but I am sorting it all out in Pine. I have to be st the full length of the bit to get my clearances so I am certain the bit didn’t move in the colette. I am leaning towards the motor current not being high enough. I was not sure I had adjusted it correctly when I first did it. When the machine crashes the servos skip without damaging anything and right now that is a good thing.
