I use John Boddy Timber at Boroughbridge, http://www.johnboddytimber.co.uk/species_az.htm
It's a 200 mile round trip for me but there's nothing better that's closer.
What it doesn't show on the...

That machine is looking very nice. Well done. G.

Hi Daniel, try some blue lock-tite on the grub screws, also make sure your using the flat type screws not the pointed type, you could also use some thin brass sheet or shimming stock (steel, ebay?)...

I have two M4 hex grub screws 90 degrees apart on the pulley boss, one screw has a flat end that tightens onto a flat that was filed on the ball screw, the other has a point that digs into the shaft....

Surely small flats on the shaft in the grub screw area should stop that. I always thought "two screws were better than one"!!! G.

Minimum of 2 screws and I always use Lock thread on both shaft and screws. If you have trouble and can remove motors without needing to remove pulleys then get the Red compound that grips like shit...

Great news Dan pleased to here it's working.

For spindle you want Ports&pins/Spindle setup/General parameters CW delay.

So Anyway I know I cut lots of parts for it but I've still not seen the...

It's only a low level signal so yes it's overkill, a simple twisted pair would do

1. You don't need a relay for the enable signal, just take a wire from the bob ENA terminal to each AM882.
2. Yes, when the estop signal is lost the bob will disable the drivers via the ENA signal...

Just into AG and p13 like the diagram on page 4, same for home switches. The home switches can be wired in series and Mach3 will take care of it or if you like, though it's a waste of inputs, each...

It's arguable but you could break circuit after transformer but me personally for safety sake then I want power killed. Same goes with VFD.? you could just send a stop signal to vfd but again for...

Hi Dan,

The way it's done is to series wire the E-stop and limits thru the 24V coil (coil not contact) of a relay. Then take the +5V signal from the BOB and run thru the contact of same relay and...
