Getting 'Cannot Unhome While Moving' Errors Withou

Hi all.

I just changed over to a new computer for my small 3 axis mill, and have gotten EMC2 2.5.0 up and running. However, I'm now stumped by the following: my machine will begin a command/move and then at some arbitrary time afterwards stop and give the error 'Cannot unhome while moving: Joint 1' (Y axis).

The only problem here is I don't have any limit switches in my machine, nor are any limit switches or the like setup in my HAL for the machine.

Does anyone have any ideas about what might be causing this? I've attached my .hal and .ini files for reference.

Thanks in advance,

Here's the .ini (couldn't figure out how to get both files in the original message:

The custom.hal is just the header and the custom_postgui.hal just contains items related to the spindle speed readout.

This configuration hasn't been modified since it was created with stepconf.

I'm at a loss... I'm very new to EMC2 but can't seem to figure it out.

I will try to create a similar machine profile and see if I can replicate the results.

EDIT: So I created another profile in stepconf, identical to the first (except for leaving out the spindle speed gui), and got the same problem, except in axis 2 (Z) while jogging the Z axis, so it is not axis dependent.

Not sure if it helps, but I did have to disable SMI on this machine (using the method detailed in the wiki)... other than that, pretty much a standard install.

just a wild guess , what breakout board do you have ?
and have you a good ground , and no earth loops etc , i know you dont have any limits etc , but thinking of either a bad earth , or a spike hitting the pc
what power supply are you using for the steppers , give me a bit more information on the electronics breakout / stepper drivers / power supply etc
