Let's see if I can explain
 I have a modbus with digital inputs I use for various functions and one of them is the machine zero position all axes. That should do the OEM code 105 if I'm not mistaken.
 In fact it worked before, but now it has happened that does nothing or does what he pleases.
 The entrance is well, is proven by changing the work to another OEM code such as booting the Spindle
 That could have happened?
 The OEM code scrits tear? if so, what and where to verify that this right?

105 is, according to the oem list, supposed to reference the axis in order but it actually homes all at once. It does work here at least but as said all at once rather than in sequence.

What version of Mach are you using?
What do you have in the script?

I use 4.043 version. I use Modbus Siliconio is a serial modbus, Use 1 input for this. I need a pushbotton for make a ref all at home.
My pushbotton work good but this dont work like OEM CODE 105. IF I use for OEM CODE 103 or other this work ok.
