I have an Altmill 2x4 and an auto z probe. It works great–I would like to slow down the movement after it touches all sides and moves to the newly identified zero position. The plate tends to be kind of slippery so I usually have to hold it at the corner and don’t like my hands that close when its moving that fast. The touch movements are slow enough. On a another note anyone create some sort of extension want so you can hold it without having your hand so close? I searched for this but cant seem to locate much info on it.

No, and it’s unlikely to be something we’d offer as a config option. Specifically for Auto Zero, the feeds and motions are relatively dialed in to be accurate for the auto/tip routines and the chamfered edge design of the plate itself.
Maybe i wasn’t entirely clear. It moves slow to touch all sides once done it accelerates quite rapidly to go to the new x/y zero location. This happens while your hand needs to be hold the slippery touch plate to the surface which is very close to a lot of moving parts (obviously the motor isn’t running) but if something goes wrong (a glitch etc.) i don’t want my hand in the way. Not really sure what the chamfered design of the plate has to do with the movement speed of how fast it accelerates to the zero location?

reduce your rapid for all axis
I’ve wondered same thing since it is very startling how fast it moves AFTER it has already done the probing and is moving to the zero point.

@iuliancalin If he reduces the travel speed, won’t that reduce it for all of this movements?
@rq6162 Question: Once it has probed all the axes, why do you need to keep holding the plate?
If I am not mistaken it finishes the last side touch and it immediately moves to the newly defined x-y zero position. Only wish it could move at the same rate that it does when defining the other coordinates.

@rq6162 Understood. Tks.
I will try this but I believe you are correct! So in a 2 inch square where you are probing I would have to dial down the rapid rate for all movements across the entire bed surface (in my case 2x4). I don’t want to sound like a PITA but it feels like it should be a safety concern and not saying changing the code is easy but if you have it moving at 300 mph/kph to go from a defined center to a spot 1 inch away why cant you make that 20 mph/kph (Just joking on the speed its moving at).
@rq6162 I’m not competent to answer that. I’m sure that someone from Sienci can/will. I don’t have the auto plate. I have the original one. I hold it down, but simply let go when it has finished probing. My hand is not close when it is making it final fast move to XY0.
Just found out that ncSender does in fact do what you want and you can even specify speed. It appears gSender is using the G0 gcode command and that is why it goes so fast when done probing.
