Homing setup and avoiding setup issues

[masso-support]

When assigning the inputs on MASSO controller for homing sensors/switches the following should be checked:

1. Make sure that once you have wired your homing sensor/switch to MASSO, the input status in the F1-Setup INPUT's list should show L (Low) and only when the sensor/switch is engaged the signal should show H (High)
   
2. If the input shows H without sensor/switch being engaged and shoes L when engaged, select the input and press the space key to invert the input. If this is not done then homing will fail.
   
3. Manually trigger your each homing sensor/switch one by one and watch the status in the F1-Setup screen change from L to H to make sure MASSO is getting the signals.
   

Homing and auto tool zero:

1. If auto tool zero is being used then after completing the homing cycle the machine will move to the tool setter position to calibrate the tool length of the current tool.
   
2. Just like the homing sensor inputs the tool setter input should show H only when touched.
   
3. Manually do touch on the tool setter and watch the status in the F1-Setup screen change from L to H to make sure MASSO is getting the signals.

Good Afternoon

I have followed the steps you have laid out above, bit after the 3 touches ie y first, then x and y, only the x axis moves away the set distance say 2mm. The y axis moves slightly and the z axis remains up against the switch. The Masso shows homing complete, but I cannot jog the z axis.

Do I possibly have wiring fault? Followed the documentation to the letter.

Hi Again

I have just watched the homing video again and I see that each axis pulls back that 2mm as the switch is triggered.

Any ideas?

[masso-support]

the pullback distance is set in the Homing settings window, you can enter value as required.

Regarding checking the wiring, can you jog all axis without homing the machine, this way you can check if the axis are moving fine.

hello. I have wired up your new 4 wire home switches but when i go to home the machine, it does not stop on when it recieves a signal from the switch?

I am recieving a high signal on the controller when tested.

Thank you for your assistance.

@mark-b-2 quite often if the drive motors have been set up correctly and there are no issues with them the homing speed can be the problem. If the motor can't slow down and change direction while still seeing the target it will just run right over it. Maybe try a much slower homing speed and see if that works. Also the accel and decel settings can effect the way the motors slow down. If it works then you can gradually adjust faster until you find the optimum setting

Hi, I have tested every possible ways, my problem is not the homing speed, even at 200mm/min a minute, Z homing cycle ends up triggering the Sensor... but it doesn't than move away by 5mm like the other axis do.

It stays there, and it ultimately either stops homing cycle... or gives me an homing error and never finishes the cycle completely.

I've check every wires, replaced the switch...

All axis moves freely in all directions, my soft limits are way larger than I need, in both positive and negative motion,

Still... What happens is this.

Anytime I run the homing cycle... Starting by the Z axis... It will only ever move exactly 10mm up and stop... causing an alarm saying Homing cycle couldn't complete... It never moves more or less than 10mm.

I tried inverting direction... same thing happens when it goes down... (just for testing) it only moves 10mm..

But when jugging, I can move fast and without any trouble de Z axis by a full 265mm total.

It really doesn't make sense.

Any idea on a configuration I could check?

Thanks

Hey,

Yes I already sent the Setting file to support, i'll be looking forward to a reply,

Best regards

Just looked at your homing settings. Don't know how you expected it to home when you haven't set a homing sequence.

- B-Axis Position After Homing: 0.000000

- Request Home on startup: Ticked Good idea to select this as well.
- Request Home after E-Stop press: Ticked

You need to select which axis is to move first, then second and third.
EG.

ahahah, Unchecked the axises so I could place the machine ''By hand'' and home it to run my codes in the mean time.

Basically, everything was the same here, but for this,
==========Homing Settings==========

- Seq 2: X: 1 Y: 0 Z: 0 A: 0 B: 0

- Seq 4: X: 0 Y: 0 Z: 0 A: 0 B: 0
- Seq 5: X: 0 Y: 0 Z: 0 A: 0 B: 0

I have split them in 3 sequence to see where it bugged.

Basically, no matter if my Z axis is 200mm from the Top 0, or 15mm from it, when starting the sequence, it will only move the Z axis exactly 10mm up, and stop... with a Homing Error light.

So to keep going, I have to Jugg the Z up to around 5-6mm from the target, Start homing sequence... then, Z moves up... hits the target... but it never Pulls back by 5 like I'm asking. It stays up to the sensor and triggers an error.

X axis finishes sequence and Pulls back 5mm (approx)
than Y/B(Slave) axis hits the sensors and pulls back... but it never finishes the homing because the Z sensor is still High since the Axis didn't pull back.

I replaced the sensor, checked wiring, polarity, EMF or ground loops... Nothing. Triggers perfectly when using a screw driver... triggers perfectly and only when hitting my target when I jugg the Z up... my Codes run flawlessly... Just can't get it to home the Z sequence properly! Very weird.

Hi Guillaume

Have a look at your inputs, especially the Z axis homing input.

Input 1: X - Home Sensor Input, Invert: Yes
Input 2: Y - Home Sensor Input, Invert: Yes
Input 3: Z-Axis Motor Alarm Input, Invert: Yes
Input 4: B - Home Sensor Input, Invert: Yes

It's the sort of thing you can stare at of hours on end it and not see and then all of a sudden you wonder how you ever missed it.

Cheers Peter

 

[GuillaumeR]

Great!

Sorry for the late reply, I fixed it and it works perfectly now

 

[Newbiedebbie]

I’m a newbie to cncing. Hoping others in the forum could give me some advice/direction. After setting up my elite oneinfinity I powered it up the masso G3 showed flashing yellow home and e-stop. From what I’ve read and seen this is correct, I pressed the e-stop which stopped the e-stop from flashing yellow to a solid white, the home was still flashing yellow. I doubled clicked but received two red alarms homing error, and the Z motor alarm. I shut off the machine and restarted followed the same steps as above but rather than double clicking on the home I went to F1 bypassed the admin password, then scrolled down to check the status of the z axis. The input 16 home sensor showed yes and low was highlighted green. Input 21 Z axis motor alarm showed no with low highlighted green. I’m assuming this is the issue should it say yes? I double clicked and pressed the space bar it changes to yes but instead of low it now says high highlighted in red. went back doubled clicked on home and again got an Z motor alarm. Restarted again, went to jog unable to jog any axis. I’m really hoping someone can help me in getting the issues resolved.

 

[tmtoronto]

Could you provide a copy of the printable settings file for others (Mass support) to look at.

Printable settings File​

The printable settings file option is available on the MASSO G3 and MASSO Touch only. It cannot be loaded back into your MASSO but it is your settings in a readable text file that you can uses as a written backup or share with others to help diagnose any issue you might have. It is one of the most valuable pieces of information that you can send to MASSO Support or share with others if you have an issue.

To save your printable file press the

button and the printable settings file will be saved as a txt file to your Flash Drive under the MASSO/Machine Settings folder.

 

[breezy]

I doubled clicked but received two red alarms homing error, and the Z motor alarm.

Is the Z axis homing direction set correctly?

Return the F1 settings to original.
Turn off homing on startup and check that Z moves in the correct direction when you jog with the F3 buttons.
If Z motor alarm is triggered during jogging then test Z motor.

MASSO Closed Loop stepper Troubleshooting

docs.masso.com.au

If OK then position Z mid axis and try homing, it should move upwards to the Z sensor, if not then reverse the homing direction in the homing screen.

 

[safeairone]

I pressed the e-stop which stopped the e-stop from flashing yellow to a solid white, the home was still flashing yellow. I doubled clicked but received two red alarms homing error, and the Z motor alarm.

I just want to make sure that once you activated the e-stop, you de-activated it before the homing attempt. It doesn’t say in your description of what you did.

 

[Newbiedebbie]

I am very new to all this. I did deactivate the estop it stopped the flashing at that point I went to f1 scrolled down being the alarm trigger seem to be on the z motor I looked at input16 z home sensor and input 21 Z axis motor alarm. I was told by another elite infinity user, the codes under invert 12-16 should say yes and status highlighted low green. And 19- 24 should say no under invert highlighted green low. Mine however says input 16 Z home sensor invert - no status highlighted green low. Input 21 invert -no status highlighted red high. Not sure how to fix when I click on the high then press space bar it changes to invert yes highlighted green low
Input 16 invert- brings me to select function screen.
