Acceleration and Max Speed seem SLOW!...

[cakeller98]

I've been using Sprinter, and just upgraded to SJFW for look ahead.

I set the acceleration and maximum speeds per axis same as I had them in sprinter, but I can't even come close to maxing out my axes. I tried jacking them up and no change. I can't get the axes to stall even... (I should be able to, in order to test the maximum speeds, and then dial back from there, but as I mentioned, I can't even get close to that.

M200 X64 Y80 Z2560 E1380 ;set axis steps per mm
M201 X2000 Y2000 Z75 E1500 ;set axis start speeds
M202 X18000 Y18000 Z240 E800 ;set axis max speeds
M206 X3000 Y3000 Z100 E2000 ;set accel mm/s/s < I've tried 1500 up to 5000 with no appreciable difference.
