Its set to 20 according to your xml, you may want to increase that.

What rev of Mach are you using?

Terry would likely be able to advise better but try at 200 and see.

You do have strange values for steps per unit with the hardware you said you have (Geckos, 5mm pitch and no gearing) If you command a move of 10mm via MDI line does it move 10mm?

strange, I just check to Genereal config, it's already 200 for look ahead.

yes it move the correct distance up to 0.3 mm accuracy if I command, maybe less.
I'm not really sure it's 5mm.

Obviously the xml you attached is not the same one you are using as look ahead is 20 and kernel is 25KHz in it.
Setting the Kernel to 100KHz is not a good thing to do if you dont need it and from your steps per unit you could run no problem at 25KHz so probably best you try that.
Also if you can attach the correct xml it may help if there are config issues.

XML looks ok from first glance with the exception of the high kernel, would set that to 25KHz and see if it helps.

For future reference you must have 0.5inch pitch screws on the X and Y and 20mm pitch on Z.
