Tool Length Sensor (TLS) Position on Longmill Mk1 12x30

Hello!

Just saw that Sienci now sells a Tool Length Sensor (TLS).

I have a good old Longmill Mk1 12x30 unit.

Any idea where the best TLS position would be?

I am thinking about the Rear Left, bolted/screwed directly to the SpoilBoard, the bracket outside of the range of the Router, bringing the TLS in the Cutting Area, removeable if it is ever in the way.

Any ideas, recommentations?

What about the TLS to Longboard connection? What port?
The same port as the Touch Plate? Other?
Any info would be great!

Thanks in advance…

Note that you need the limit switch upgrade.
I don’t have a Longboard controller but I am assuming that just like the Altmill controller, there is a port called ‘TLS’. It is a 3 pin connection which re-uses the two touch plate connections (internally in the controller) and provides a line for power.

Indeed, i forgot to state i already had the Limit switches.

My longboard version and connectors list: (Sorry, not clean!)

Ok, I will take a guess at this but you really should send a quick email to Sienci …

The TLS will have 3 wires:
ground to your ground
probe wire to (drum roll) probe
and the last wire to 5V

Of course that doesn’t help when I can’t tell you which wires on the probe are which and Sienci can advise you.

Double check with support, but the wires are labelled on the tech documents in resources:

It’d be ground + signal (2 + 3) to the board and the remaining to external power.

Support should have more in-depth instructions for the longboard, so do email them regardless.

Just got an answer from Sienci Support

They state: (verbatim)

It has to have the SLB not the LB.

The website state it work with all Longmills even the MK1. What it does not say is that you will need a Super longboard.

I’m speechless…

I looked it up and they state that:

Any size LongMill MK1 or MK2 with an upgraded SLB controller (requires inductive sensor kit)

Having said that, if you can operate a touch plate with your controller than you can operate the TLS BUT they also say that gSender 1.6.2 is required which has all the logic in it to make it go. If your controller can’t run 1.6.2 then you would have to build the appropriate macros yourself and that isn’t an easy thing to do.

ho!

I think I figured it out…

The announcement email state:

Compatibility

LongMill MK1 - 2.5, any size (requires limit switch upgrades)

the purchase page state: (in red)

The inductive sensor kit for LongMill MK1-2.5 is required to operate a TLS. Buy Now.

gSender 1.6.2 version is required to operate a TLS. Download Now

I looked to see on:

But you are right at the bottom of the purchase page it says it…

sad…:worried:

Thanks…
