[Atif (Atif Ali)]

Thank you for attention.

Can you help me in this regard?

[Atif (Atif Ali)]

I am waiting for your reply please.
How to enable homing in GRBL setting.
In other word how to rectify red line shown in picture I have limit switches in k40

[jkwilborn (Jack Wilborn)]

If you count there are the same amount of pins, likely just a different types of connectors.

Does your machine have ‘home’ capability?

If so you can enable it within the ‘Edit → Machine Settings’, don’t forget to ‘write’ it back to the controller after you modify it…

@Atif

Connection mks dlc 2.1 laser 50w-no fire

I keep asking him that, but he seems convince it’s not wired properly. I’m starting to think he wants to see it’s smoke.

here there is a wiring diagram, look at post 25

[JohnJohn (John Johnson)]

there is a minor difference between the two supplies.

The test fire button wiring appears different. Is a different strategy being applied?

Also, in the diagram, is L to be grounded when the test button is pressed?

[Atif (Atif Ali)]

Thank for attention please guide me little bit more how to write in controller setting to modify it.
I am newer in this field

[Atif (Atif Ali)]

According to your knowledge its minor changes in both power supply but I am newer and have little bit knowledge about it.
So please help me how to wire up shown power supply.

[Atif (Atif Ali)]

I have already visited that page here he clearly mentions about connections of pin G & IN in K40 power supply I also know about pin P+ & G.
I am confused on connection of pin K-, K+, L, 5V,G and 24 V?

[Atif (Atif Ali)]

Sorry i came again to disturb you.
Homing is enabled in GRBL and issue is rectified almost.
Now i am facing a new problem which also relate to homing.
When axis go to homing position its halted and did not come back and a message came at LightBurn console is shown in picture.
I used limit switches in Normally Open Condition, 2ndly when it move to seek homing motion of motor is very slow.
Please guide me in this regard.

[jkwilborn (Jack Wilborn)]

How are these, marked in red, set?

[Atif (Atif Ali)]

I did as you directed but situation is same.
Please see Pictures

[jkwilborn (Jack Wilborn)]

Generally when the limit switches are NO, the switch pulls the line low.

You have ‘Limit pins inverted’ enabled… I would think that should be false or disabled.

The machine with this photo has NC limit switches…

I’d disable the ‘limit switch invert’ option…

[Atif (Atif Ali)]

New problem started as i diable “Limit Pins inverted”

[Atif (Atif Ali)]

Please check Blue area of picture may be i am also facing same issue.
if it is then how can i make it off of Z axis home in easy way…

[Atif (Atif Ali)]

I connect it as shown in picture. Now issue is when i fire up laser from light burn 1stly i need to press fire button then push K- and K+ then laser tube fire up for testing.
when i put drawing and give command to lightburn to run job in MKS DLC32 Light up indication but laser tube did not work. please help me how to resolve it. I did not connect L pin with anyone.
For test check i Connect L Pin with CNC Spindle Negative pin but there is no change in behavior of Laser Tube.

[killrob (roberto ceccherini)]

[Atif (Atif Ali)]

Hello, I came again to disturb you.

According to my little bit knowledge Y axis gantry did not comeback at which position it started the job.
I change $27=8.000, $27=7.000, $27=6.000, $27=5.000, I tried these commands also but no change in behavior of machine. Sometime another massage displayed in console which is

Please help me how to rectify it.

[killrob (roberto ceccherini)]

and you did not answered to my question.

[Atif (Atif Ali)]

Please check what i did.

[Atif (Atif Ali)]

as i am remembering/recalling of memory about my failure is when i press fire on LightBurn and connect K- and K+ pin laser tube fire up.
But when i gave some sketch to draw the laser tube did not fire up because i did not connect of short K- & K+ pin.
