Homing timeouts #4

Open mrandt opened 9 years ago

mrandt commented 9 years ago

Homing X and Y can time out on larger machines. Mine is 630x530. As maximum travel distance and speed is known, we could calculate a realistic timeout.

compute the formula for me and i'll implement it. base it on values derived from tinyg.

I looked into this and it seems that the timeout is actually in TinyG firmware, as homing is just initiated by a G28 command... :cry:

Any chance we can set this as a property?

Formula would be simple: max timeout (x) = machine size (x) in mm / homing speed per second (x) in mm

Probably should 10% or something as safety margin.

It's in cnc.cs

Question is what tinyg variables go into computing travel speed
