Re: [Emc-users] Starting up in Machine ON
Hi There…I’m hoping to start in the ‘machine on’ state rather than estop on. After that, yes, I would like to home the axes, then set the mode to MDI and also set G93. I had not asked anything but the machine state as I thought it would be better to take it one step at a time… Thanks very much, Alan Sent from my iPhone > On Dec 18, 2023, at 2:09 PM, Todd Zuercher wrote: > Probably, but we will need a better explanation of exactly what machine > responses you want to what machine inputs, before we could give a detonate > yes or instructions how to do so. > > Are you asking for the machine to automatically home all joints when the > machine power/enable button is pressed? > > Are you asking for a reset button that returns the machine to a ready > position after an incident or interruption of a program? > > Something else entirely? > > Todd Zuercher > P.

[Emc-users] Starting up in Machine ON
Hi There… We have a positioning machine that uses linuxcnc that we want to better automate the restart procedure. Is it possible to script in the initial file for the system to switch to Machine ON (as long as there are no active limit switches). This machine is inaccessible to humans without turning off power, so there is no safety concern.
