Yes that is normal. There is no way Mach can know where it is until a Home has been done so there would be no way to know where to slow down.

thank for your fast reply Hood
yes indeed, it's true Mach don't know where is it until a home but in this case the slow zone is a little bit useless because when manually jogging the machine the operator should keep he's eyes there and see where the machine is moving

I'm thinking now for a procedure to have rapid movement for homing, something like zeroing the tool height in big-tex's blue probing screen set, in 2 steps.
first step at a higher speed, until home and then, after a short retract, the second step with slow speed for getting a higher accuracy.

I think an improvement like this will be useful at least for large machines with heavy gantries. If I'll have time and "inspiration" I'll give a try and post here the results. Hope will be positive. Smiley

Best regards,
Seb

This will home at the homing speed in Config>Homing/Limits, then home again at 1/10 the speed.

So if you set the Homing speed at 50%, it will home at 50% first, then 5%.
