General Mach Discussion / X axes loosing steps, helps pls
« on: October 07, 2013, 06:51:58 PM »
Hello,
I have built a router for wood working, with servo motors, Y and Z axes are ok, but X axis is loosing steps when it accélérâtes a little bit.
I use geckos 320x drives with digital encoders 500 lines. servo motors KL34-180-90 and power supply of 72 volt.
X axes is working with A axes as slave. pully 2:1 and screw of 10mm pitch.
Y and Z axes 3:1 and rhe screw is also 10 mm pitch.
the prblem is when the machine is cutting it does not loose steps, but when the z axes is up and it moves x axes fast it looses steps and motors bocomes jerking or something like that.
I usually use 500 for the feedrate .
I have attached my xml file, if it will be needed.
hoping to get your help.
thanks a lot
