thanks guys for the reply's just changed them to match and we will see what happens.

I have a question about tuning my corexy printer.

I used the online configurator to make my base files. Got everything set and tunned except the accelerations. Can someone tell me why it set the y value soo low compared to the x value on the m201 command?

M566 X900 Y900 Z12 E120 ; Set maximum instantaneous speed changes (mm/min)
M203 X10000 Y10000 Z1800 E2200 ; Set maximum speeds (mm/min)
M201 X500 Y20 Z250 E250 ; Set accelerations (mm/s^2)
M906 X800 Y800 Z800 E750 I30 ; Set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout

Can i change the y to be the same as x?

It prints fine just want to tune it to bring out the maximum potential of the printer.

do i have to redo my config file after the update?
