Yes, you got it figured! 

[Stevo]

How does the toolsetter actually work i know when the cutter comes down onto it trips rises and lowers but what happens after that ? 

 

Trying to figure out homing i did put it on discord but no one replied so i removed it.

If you manually depress and hold the end-stop and input M119 in the console does it show it triggered? Did you install Millennium OS?

No, it is not an issue, the Millennium uses a setup wizard for the probes. For the tool setter it probes the tool to know where it is located then it probes the bed manually so it knows the height of the tool setter not sure where that info is stored.

I don’t plan on using a probe but I will use a tool setter will ask on discord how to add the tool setter later 

[PFarm]

Maybe try loading the Millennium OS go through the setup wizard and see how the mill reacts. Comment out anything you don't want, and modify parameters to suit your machine (do that in user-config.g) To go through the wizard you'll need to have all the hook-ups completed including the spindle. You can choose not to install items to don't want like touch probes etc....

Will do thank you very much for the help its much appreciated its just this is not my thing ! 

I have taken out 3 micro switches today and just plan to use 3 to home at the front right hand corner. Then use entries in the Limits .g file to restrict excess movement.

Its all very crude at the moment but once the layout is more defined i will see about a box to fit the electronics into.

Sorted out my maxima travel for the three axis's so can enter that into the limits g sys folder

Hi do you have the speech marks or not ?

 

 

; Configure emergency stop input. You must set the C"..." parameter to
; the pin identifier where your emergency stop input is connected.
M950 J1 C"PD15"

; Fire trigger 0 (emergency stop) on status change
M581 P1 T0 S1 R0

; Check e-stop is not active before continuing startup
echo {"Checking E-Stop status..."}
M582 T0
echo {"E-Stop is not activated, continuing startup"}
 

 

[PFarm]

This is my e-stop.g:

The physical estop switch is wired to E-min end-stop signal pin PD15 and Grd. The other side terminal of the estop has a wire the negative wire from the 24V. The power supply goes into the e-stop and exits the contactor coil. The other side of the contactor coil is connected to the positive of the 24v power supply.

Thank you E stop and end stops and limits this week 

im not sure whether to flash with millenium or not I want to add a tool height setter and that’s about it I don’t cut metal just timber and use vectoring aspire for creating cutter paths etc so don’t see it being extra value to my setup.

may I see your tool height setter code please 

thank you

Hello my friend well im really struggling to figure out how to home this thing !

I want the machine to home in the front left corner with the spindle at the top of its travel so this would be X- Y- and z+ correct ?

Homing switches are not showing triggered ? however leds on the board extinguish when tripped.

I have set the vlim jumper to 5V  ? using mechanical micro switches NC and altered the limit section as follows

 

; limits.g - Configure machine limits and endstops

 

; Set axis limits - minima

M208 X0 Y0 Z-350 S1

 

; Set axis limits - maxima

M208 X1450 Y2200 Z0 S0

 

; Endstops

; Spindle to move upwards in the Z+ direction to home Z axis

; Spindle to then move to the left of the machine in the X- axis direction

; Spindle to then move to the front of the machine in the Y- axis direction

 

; Endstop X=MIN: NC

M574 X1 S1 P"PD_11"

 

; Endstop Y=MIN: NC

M574 Y2 S1 P"PA_8"

 

; Endstop Z=MAX: NC

M574 Z2 S1 P"PD_12"

In the photo, the probe shows "1000" because it's disconnected or you need to add ! to invert it?

Do you see the end-stop leds lit like in the photo below? Note: Your leds would be -Y

When you depress the endstop manually does the dashboard machine position light up to the correct axis?

[Stevo]

Yep im getting somewhere now i tried homing all just for to see what would happen z homes ok x homes ok just y axis goes in the wrong direction 

 

 

[Stevo]

[Stevo]

How do I reverse the homing direction for y axis homing please

[PFarm]

There are two ways to reverse the direction of the stepper one is the swap the A or B stepper motor connection that can be done at the stepper connection on the Scylla or in your drive.g change the S0 to S1 or S1 to S0 for your A/Y drives. Drive.g is the easiest way to swap direction you since your using two steppers to need to mod both A and Y.

Example

 

 

; Physical drive 1 (Y) goes forwards using default driver timings

M569 P1 S1 to S0

The motors all run in the correct directions it’s  just I want it to home in a different direction

Sorry about that! In your setup standing in front of your machine:

X = homes to the left?

Y = to the front?

Z = Up?
