3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

[Michael82]

Yes
That BOB will be easier with the screw terminals to connect to
Attachment 431332

I would still use the larger 1XHCEL Board relay to keep the mains away from the BOB !!!!

2nd BOB to 1XHCEL relay board

Hello john ,
I'm just now getting to wiring this up I have a question ....in the diagram it shows a green box labeled spindle control is this going to be the ( modified power supply with the potential dial ) or is this the actual spindle motor

[Michael82]

I really needed specific locations I know the wires go to the spindle control box but where? and the diagram shows a battery ?? could this be the 12 volt power supply I have added ? HELP PLEASE

[john-100]

post 101 - the green box is a mains powered load switched on & off by the relay

in the diagram its shown as a pump but in your case it can be the speed control for the spindle motor


post 102

if its the 12V supply shown on this diagram



then yes


photos of the boards you are now using in your machine will be useful and the manufactures part numbers

so I can double check what you have now

Hello john ,
Here is a list of what I have in my controller box

1st picture is 12 volt power supply to run my fans inside the box .

2nd picture is of the spindle control box that has the pot knob and it is 48 volt output

3rd picture is a view of the terminals of the spindle control box

4th picture is of the other power supply running the stepper drivers

5th picture is of the terminals of that power supply for the stepper driver

6th picture is the 5th axis breakout board

And the 7th picture is the relay for the spindle

The last picture is of the new enclosure which is an old pc that I have converted into a new enclosure there is still a few loose ends there so please feel free to give suggestions

Hi Michael

Its going to take a little time to produce a wiring diagram for the connections of the contactor to the spindle motor speed control / power supply

provided the relay can cope with the switch on surge current

use the relay to switch the mains supply to the spindle speed control / power supply



needs work but this is a start until I have sorted out the PC




I need to make space on this PC's 2Tb C drive as it only has 2.54 Gb of space !
having downloaded some very large files today

I need be able to use it to buy tickets at 9 am tomorrow for a concert in October so I don't want to dig my self into a hole just now
its too easy for a simple job to turn into a nightmare - been there done that

Once I have the tickets
I can leave it backing up / moving files all day, including while I at the Caravan Palace concert
{they are a French electronic music band }

This is perfect for a start ...no problem john when ever u get time and have the resources. You have been a very big help they all of this . Thanks in advance for all the help

[john-100]

Hi Michael

it is still a work in progress but is a wiring diagram for the spindle
if your not using a charge pump



note- the BOB shown needs a 5V supply from a USB port

Looks good john I have 1 question what's the no volt release switch for ? What would that switch be used for??would I use it everytime I run the machine or just when I need to shut the spindle off like a estop

[john-100]

while you can do without a no volt release switch

The no volt release switch prevents the spindle from starting unexpectedly
after a temporary loss of mains supply or when you switch on the power to your workshop

When using A PC's printer port the outputs will be at random levels at start up
until windows & mach3 are running correctly and has control of the printerport

Oh I see do u have a recommendation, brand , type ??

[john-100]

a no-volt release switch used on many mini lathes and milling machines is the
KJD17 5-Pin Start / Stop No Volt Release Switch



there is a 4 pin version but the 5 pin KJD17 makes it easier to add remote stop switches

seeing your location you need the 120V version that the likes of Little Machine Shop sell

https://littlemachineshop.com/produc...5527&category=

not the 240V version I would use in the UK !






if you don't have to keep the cost to a minimum

a Direct On-Line (DOL) Starter is an alternative

with some manufactures you can buy DOL starters with & without a current over load
and various coils AC or DC for 24C , 50V , 110V , 240V & 420V use

Hey john I have finally got this all hooked up besides the e stop ..so I only need to use the live wire in the e stop and back out of the estop??

[Michael82]

Referring to post 107

[john-100]

assuming you have the KJD17

a N/C E-stop switch can be wired between the KJD17 terminals A1 and 24 to remotely switch off the KJD17 and kill the mains supply to the machine


if you find a 2 pole N/C plus N/C E -stop switch instead of the more usual N/C plus N/O you find on the likes of E-bay

the second N/C contact can signal an E-stop to the PC

this has the advantage that a brocken wire to the PC N/C E-stop will be detected

using a N/O contact works but does not detect a broken wire !!


(some E-stop switches are available as the push button mechanism that you have to buy the individual N/C or N/O switches but they are usually more expensive )

see page 12

John

[Michael82]

This is the estop I have

[Michael82]

That does sound like a better e stop but for now I will hook this one up thru a1 and 24 terminal until I get the new n/c , n/c estop

[john-100]

yet another version of an E-stop switch with just 3 terminals - a common . N/C and N/O

with this switch you can either connect it to the KJD17 terminals to kill the mains supply
or to the BOB to signal an E-stop to the PC but not both

killing the mains supply will stop the machine once the energy stored in the power supplies is used up

an E-stop to the PC via the BOB only works if the PC and control electronics is working correctly

I have had motor drives fail and run away with motors running over speed in an uncontrolled way !!!
(series pass transistors go short circuit and apply full power to the motor )


John


PS

if you use your E-stop switch to control the KJD17

a small 120V AC relay could be connected to the KJD17 output

the relays N/O contact can then be connected to the BOB's E-stop input

depending on your parts suppliers this could be less expensive than a E-stop switch with N/C plus N/C contacts

I agree with u on this john and this is the whole point of adding the relay was to be able to have more control over the machine when the estop is needed . So I am ordering the n/c n/c estop to be able to connect the bob and the relay to the same estop , I will let u know when it arrives

John I need ur help ...I got the estop u recommended n/c n/c .....can you please draw out a diagram I see in the post from the 1st time you drew it out but I cant make heads or tails of it . I use the 24 from the no volt on /off switch to the 23 on the e stop then out of the estop to the relay. I am not sure what to do with the a1 terminal??

John I am having trouble with understanding the a1 terminal...I got the 24 terminal going to the relay
