Ready Steady Eddy

[EddyCurrent]

More progress, getting there now.
If anyone thinks the energy chain looks big, I still have some 8mm pipes to put in and at least one more cable.
Junction box on the machine, the cables from the panel will festoon down to allow movement of the machine but they will probably have some spiral wrap around them eventually.
On the right, inside the junction box, you can see where I've just passed the spindle cable directly through the box, this is to have no additional terminals between the VFD and the spindle motor,


Energy chain now arrived and fitted, note the grey plastic curved piece to transition the cables form the tray to the junction box. This was made from one of my favourite sources of material, soil pipe offcuts. The 110mm soil pipes are made from plastic that can be shaped with a paint stripping heat gun, just cut it lengthways and slowly heat until it lies flat, you get a piece over 300mm x whatever length you cut.
I used Dexion slotted angle iron for the energy chain trough mainly because I've had a load sitting in the garage for years. With energy chain it's advantageous to have a trough that is open because it allows debris to fall through without collecting in the bottom causing all kinds of problems.


A small aluminium box just fitted nicely under the energy chain bracket to allow connection of limits and home switches.


Just a view from the front. Unfortunately my great set up is no good now because the energy chain crashes into the keyboard and monitor bracket so a bit of rearranging will be required.


Got it going to it's home position today but there seems to be an issue with the slaved A axis, I might have to fit a switch on this after all. As it is with just a home switch for X, it reaches the switch and just comes to a halt, unlike with Z and Y where it backs off slightly. I tried unchecking the home limit selection for A in Mach3 but that made it worse. Will have to read up tonight about options for that, further reading on this subject here http://www.mycncuk.com/forums/gantry...is-gantry.html
