I didn't know that I could use one input for all homes, except the slaved axis I presume. do I have to run a jumper between the pins that Mach is assigned for the homes and limits as it fails if I have the same pin assigned in two places.

I do have two paralell ports however. I will be operating several other options with them though, ( dust collector, spindle coolant, tool changer options ect.

Where are you at that it is colder than Alaska??

I am in Scotland, the UK has been having a colder than normal spell of weather, its not got above zero for probably 4 weeks here and even during the day it has been regularly -7 or more and often going into double minus figures during the night.

Are your switches normally closed? If they are then you can wire them in series and use only one input and set that one pin in Mach for all the Home and Limits. Slaved axis may require separate switches but not sure as I have never messed with them.
When you say it fails if you have the same pin assigned what do you mean?

Scottland!, My wife really want's to go there. She has some distant relatives there.

The manual with the board says I can't have the same pin assigned in more than one place.
Is Mach OK with assigning two inputs to the same pin number? Could it just be the BOB that wont accept that?

Thanks Hood
Arturo replied on Christmas no less! now there is some support for you!
I was missing one of the two 5V connections that I thought was to power the optional relays.
It was not optional as I thought since it powers the other side of the board. Everything is working now. ;D

Is there anything I can do to get more speed out of my motors? I turned up the velocity in motor tuning but am only getting 130IPM on the Y&Z(ball screws) but am getting 400IPM on the X(rack and pinion). The motors don't seem to spin as fast as I expected. Will turning up the pulse speed increase the motor RPM?

If you are meaning that you can not get more Velocity on the motor tuning page for X and Y because it is at Max then yes you can increase the kernel.
If however you are meaning your motors are stalling at 130IPM then no increasing the kernel wont help.

OK
I am going to bump up the Kernel speed and see what happens.

That worked, up to 230IMP Y&Z and 500 X.

I am now trying to get the slaved axis to work. The motor is powered but I am getting no motion.

I don't know what I am doing wrong. I set the slaved axis X to A and rebooted, only the X runs. I messed around with homing and limits, still no movement.

Any Ideas???

Do you have the Port and Pin set for the A in the Motor Output page of Ports and Pins, remember its not the same port and pin numbers that the X has but it is whatever you have the A connected to.

Yes, they are set to the Mfg port diagram. and I did change the A to linear insted of rotory.
