New CNC Mill on the horizon

Thanks Dean

So am I right in thinking that the default on these drives is enabled? unless instructed otherwise as in the manual for the DM it says these are not usually connected, I have seen many wiring diagrams now where they are and I fully intend to just a little confused as to why they would say not normally connected

basically will the drive still work if these are not connected I think is a simpler way of putting this!

Yes they will work fine if not connected. Yes and No to default being Enabled. To understand better how the Enable feature works some understanding of the feature will help.
The Drive signal inputs by Default are enabled and when you use the enable feature what your actually doing is turning them off.
One of the main reasons to use the enable feature is so the Motor stays powered up. The enable signal just disables the drive inputs
and leaves motor under holding torque.

This is fine for Say limit triggers for when other axis need holding Ie Z axis and when leaving machine for any length of time when Mach is not Re-set so motors or axis can't accidentaly moved. But Not when in E-stop situation when really power should be removed from the drives.

Dean thanks, I am putting a fully latched safety circuit on the machine just could not get a good grasp of how the enable worked so thanks for that!

So whilst getting along with the electronics circuits I am going to start to fashion some machine guards to protect both me from the machine screws (I have a tendancy to get too close to the machinery - through no fault of my own) and also to stop flying chips and debris getting into the screws.

Whilst at that I want to run some ally channel so I can have the E chain run along side the guards, what size chain do people generally use for the various bits of the machine?

I can see at the moment I am likely to have:

z axis - spindle main cable, z axis limit and home switch and water pipes for spindle, z axis motor cable

y axis - All the above plus the y axis motor, y axis limit and home switch

x axis - all the above plus the x axis motor wire, x axis limit and home switch

Any suggestions on size?

I can get hold of up to about 50 x 20 from a local supplier but its pretty pricey p/m
