some times I think the problem comes from gecko drives. all gecko drives that I have are set to 11 o'clock. could I set them for more than 11 o'clock to have more current? if yes, do you think it will resolve a little bit the problem?

thanks

Ok ,
Now I use pullies 3:1 and 2:1. My question is if I use pullies 1:1, what do you think, is it possible?
if not what kind of servo motors do advise me to have, which can be driven by gecko 320x?
thanks

I put 3330 in the velocity and 410 in the acceleration. it is ok and every thing is going fine. but it is not fast. I would like to have a little bit more speed. is there some thing to do for having more speed?

Thanks

I have just tried it but there is no use. I put from 1 to five , but the problem is still the same.
I would like to to add another thing that may help. I have to power supplies , they are the same. I have wired the x axis to the first power supply, and the A (slave axes) to the other one. do you think the problem comes from ? should I power the 2 axes, X and slave to one power supply?

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
Robhi
