Help with how to wire touch plate to a CNCEST 3040T CNC router with parallel port

[cvuxton]

I have a CNCEST brand 3040T CNC router using Mach 3. It uses a parallel port interface. I'd like to incorporate a Z Axis Zero Touch Plate. Its a 4 axis model so the additional socket in the second picture is used for the 4th axis. Does anyone have one of these that has connected a touch plate? How did you do it? Th efirst picture shows the guts inside the control box. Power supply is off to the left.

Thanks for the help.

Chris

Do you have any documentation for the control box?
If not, ask seller to send it to you.

No documentation. I'll try to get in touch with them.

No luck getting hold of CNCEST. What a waist of time. Does anyone have a manual, or scan of one for this beast?

Thanks.

I have a 3040t but no 4th axis pm me with email I will scan mine and send it. Warning it is useless and unless u can understand Chinenglish it is very hard to make heads or tales of it ...you are gonna need to take some pics of the bob( breakout board ) does it look kind of like this

I too are wanting to do the same modification.
A sprung loaded touch plate fro Z axis.
so far Pin 15 is the pin in question and set the table to activate when grounded.

Unlike you and most on here my machine is very very old and must of been one oft the very first machines sold on ebay some 7 plus years ago.
a simple Tolson circuit set of 4 control boards controlled off a parrallel breakout board and driven with a 24v dc PSU.

im planing on ripping out all this wiring in this box and putting it into a comput case for added space and give me room for additional powersupply.
2x 24vdc PSU 6Amp (as supplied and a 10amp just ordered in.
ive ripped out the flexi drive type of motor control board in favour of a 600watt air cooled motor and a 0 to 10v controller which is stand alone.

Ive not yet got the spindle control in anyway totally manual.
still got to check the settings to find out what where etc.

if i find out any more on the touch plate i will let you know.

Hi.
Can you solder?
You'll need to and well.
OK probe connection has nothing to do with 4th axis.
Remove your break out board.
Find pin 15 from the 25 pin parrallel connector.
Solder a wire onto the board.
If you follow the circuit you will find an empty hole.
You ñeed to route a wire to the probe.

The base of the touch plate to ground
Go into the set up and set the probe to activate low
And enable.

Hope this helps
