CNC TB6550 Board Arduino UNO Board Estlcam

[genesiospinola]

Hi Genesio

I connected an Arduino to my PC yesterday and can see Estlcam can control the Arduino
but I have not found any information on how Mach3 can comunicate with the arduino

I would of thought Estlcam would add a "plugin" software patch to mach
like other motion controllers do to replace the Mach3 "pulse engine " software that controls the printerport hardware

John

Hi, John.
Got it. Now I'm looking for a script that can "auto Zero" the 3 axes x, y, z (auto zero button) using mach3 ...If you know...tell me about, please.
I do not think I'll be able to use Estcam and Mach3 ...
Thank you!

Hi John!
Could i use this script below in Mach3 to auto zero, and how can i adjust. I use metric unit (mm), 6mm bit, and no touch plaste, but aluminium tape, that i think to put front of the material (y), right of the material(x) and top (z).
Thank you!

yes , the mach 3 set up needs to be changed to match any change in your wiring

if you connect your E-stop , probe & limit switches to the 4 wires shown in the picture in post 29

you will only have one common wire , the probe on pin 10 , stop on pin 13 and all your limit switches on pin 11

this will enable all the connections to use the opto-isolated inputs on the TB6560 board

if this limitation is a problem , then you will need to make some connections directly to the arduino

one possible way could connect the stop & probe via the TB6560 board
and the 3 axis limit switches directly to the arduino

Hi John,
In thinking to use limit switchs. Pins 11, 12 and 15. Where i find the pin 15 on pb6550 board, please. Probe pin 10, E-stop pin 13. Or... pins 10, 11, 12 for 3 limits switchs. Pin13 e-stop and Pin 15 probe.
I am using the USS (USB SmoothStepper) board. See here https://warp9td.com/index.php/products
https://warp9td.com/index.php/documentation/doc-uss

What you think about?
Thank you!
Genesio

[john-100]

your TB6560 board does not have pin 15 connected to a terminal that makes it easy to use unlike the other 4 inputs (pins 10 , 11 , 12 and 13 )

without soldering wires to the board to use pin 15
the easiest I can think of other than using the second port on the Smooth Stepper
is to connect 3 IDC 25 pin D-type connectors to a 25 way ribbon cable instead of a normal printer cable
( the IDC 25 pin D-type connectors are used on the cables made for the Smooth Stepper)

the only downside is your connecting directly to pin 15 ! on the Smooth Stepper
( I will have a look for a ready made opto-isolator board )

as for your earlier question in post 42 about scripts , I don't know !

as I have not used them ! , its some thing I will need to look into again
I did try using the same PC as used connecting to the internet but Mach 3 didn't work well with all the other software running in the background so the project went on hold for a while

I just need to built PC just to use / experiment with to control a CNC machine -
or replace the DELL Optiplex 755 I am using for the internet
as I want to keep the asus H110M-D based PC off the net as it has my PDF library of books magazines
(after all the various upgrades I think I have enough parts for a 3rd PC )

Hi John.
I didnt understand how to do this to use the pin15(maybe the probe).

"without soldering wires to the board to use pin 15

is to connect 3 IDC 25 pin D-type connectors to a 25 way ribbon cable instead of a normal printer cable
( the IDC 25 pin D-type connectors are used on the cables made for the Smooth Stepper)"

The limit switch can be like this? How many I must use?

.
I have a MacBook to use 3D software. I use a Notebook Acer Win7 to run Mach3. But before I must to solve these questions... ��




Thank you.

I'll try to do this



Three pins for limits 10, 11, 12
One pin for e-stop
And pin for Probe??

Thanks

Genesio

[john-100]

using the smooth stepper , a breakout board like this C25 could make the connections easier and protect the smooth stepper



after looking at the photos of your limit switch I found on line
I have worked out how the microswitch and LED is connected



I would connect each switch to individual inputs on the smooth stepper

( connecting the switches in parallel would short circuit the supply

and they would not work in series unlike the switches shown in your diagram )


John

PS
the web link to the wiring diagram use in post 46 would be usefull

[genesiospinola]

Hi John,
I bought now


How can i do this? I have to buy the breakout board like C25? How to connect the wires? Please.https://cnc4pc.com/c25-smooth-steppe...nal-board.html
"using the smooth stepper , a breakout board like this C25 could make the connections easier and protect the smooth stepper"

Will be like this? Where i must connect the db25 connector from tb6550?


Now is like this


I thought to do this see here Wire Limit Switches


Three pins for limits 10, 11, 12
One pin 13 for e-stop
And pin for Probe??

What's is better, or can be done, buy the C25?

Thanks

Genesio

[john-100]

you don't have to use a C25
as the TB6560 board does not have pin 15 connected
the simplest solution is to connect the TB6560 board to port1 using the smoothstepper 26pin to 25 pin D-type cable

and connect the probe to one of the inputs of port 2 using a ready made opto isolator made for the Arduino to avoid a direct connection between the smoothstepper input and your probe


John

[genesiospinola]

John,

So i connect like i do now: the tb6550 to port1 from USB Smooth Stepper


I did not understand the connection: probe to port2 from Smooth Stepper. I must connect only one wire from probe(IN). The ground wire from probe i use from tb6550, like this is now... What is "opto isolator"? What pins i have to use in port2 from Smooth?
"and connect the probe to one of the inputs of port 2 using a ready made opto isolator made for the Arduino to avoid a direct connection between the smoothstepper input and your probe"
And how to configure Mach3 to use Smooth's port2 pin?


I think i am almost there... ;-)

Thanks!
Genesio

[john-100]

as the TB6560 board does not have a terninal for a connection to pin 15

the I assume you are going to connect your limit switches to 3 inputs and your e-stop to the fourth input


thats easy by connecting the TB6560 board to the ribbon cable you have


by adding a second cable to your smooth stepper
the probe could be connected to the ground and an input pin of a 25 pin connector pluged into the second ribbon cable

in mach 3
the probe will have to be assigned to port 2

the 4 inputs on the TB6560 board are connected to the 25 pin connector via opto isolators

to me it makes sense to connect the probe via another opto isolator

while you can solder a PC817 and a couple of resistors to a piece of "veroboard"

ready made boards are available for the Arduino

they prevent stray currents damaging the smoothsteppers inputs

john

[genesiospinola]

John.
Ok.
Sorry...
But i did not understand
how to do: by adding a second cable to your smooth stepper (one wire?)
the probe could be connected to the ground (the probe ground can be connected in tb6550 like now?)

and an input pin of a 25 pin connector pluged into the second ribbon cable
i did not understand how to do this
I put one wire in Smooth's port2? Where?
Can i use this wire to connect to Smooth's port2, for probe?



Thanks
Genesio

[john-100]

you will need two wires need one to the ground ( pins 18 to 25 )
and one to the chosen input as configured in mach3 - say pin 10
just as you have for port 1 for the 3 limitswitch inputs and E-stop

John

PS

while you can connect the probe directly to the 25 pin plug

this is the first result searching for arduino opto-isolator



that when connected to port 2 would duplicate the 4 opto-isolators on the TB6560 connected to port 1

[genesiospinola]

port1 Tb6550 board
pin 10 limit x
pin 11 limit y
pin 12 limit z
pin 13 e-stop
pin ground (e-stop ground, probe ground)

port2 Smooth
probe--->>>opto-isolator IN 1--->>>opto-isolator OUT 1--->>>pin ? port2 Smooth

Probe: this wire


Put probe wire here IN 1


Probe wire OUT 1 from Opto-isolator --->>>>to Smooth port2 pin 10, for exemple

Is this John?

(I did not understand this
"while you can connect the probe directly to the 25 pin plug that when connected to port 2 would duplicate the 4 opto-isolators on the TB6560 connected to port 1")

Thanks!

[john-100]

yes , thats correct
in addition to the signal connections the opto -isolator board will need a 5V supply as well
I think you can take +5V from the TB6560 boards remote control 15 pin connector

john

[genesiospinola]

Ok. I have to see this, if i find what you said.
"I think you can take +5V from the TB6560 boards remote control 15 pin connector "

And...can i connect the probe wire to any port2 pin, from Smooth?

Thanks
Genesio

[john-100]

you can use any input pin on port 2
I'll need to check but pins 10 to 13 + 15 and pins 2 to 9

with ref to post 54

(I did not understand this
"while you can connect the probe directly to the 25 pin plug that when connected to port 2 would duplicate the 4 opto-isolators on the TB6560 connected to port 1")



this is the 14 opto-isolators on your TB6560 board


with the added 4 channel opto-isolator connected to port 2
you can duplicate the 4 inputs on the TB6560 board

John

PS
going by the manual for the TB6560 board
pin 15 on the 15 way remote connector is connected to +5V

[genesiospinola]

Ok John. Port2 from Smooth, right? I understand now.

And where i find the 5V from tb6550 to connect to the opto-isolator?
I am not finding the opto-isolator here im my city yet...Is there another option?

This pin 15 is not a possible input for the probe?


Have i to activate port2 on Mach3?


Thank you.
Genesio

[john-100]

on the 15 way connector
pin 15 a +5V output to power the wired remote for the TB6560 board

what type of probe do you have ?

if it can be isolated from your machine you could use a coaxial cable to connect it directly to the smooth stepper port 2

John

[genesiospinola]

My probe is like this


Could be like this?
