Manual probing acting loopy?

gabrealek

Hello. Here I am again here. Ive been manually probing for a while because my z axis switch was broken. i have since replaced it but still preffered to use the manual probing. I havent printed in two days, so i turn my big baby on and shes making a grinding sound and going to the right until she hits the right bar. Im completely lost her so I will post my config and homeall here. Thank you all for your help!! I will include a picture as well.

When i press HOME ALL this is where she goies

this is where she went after i pressed ok on the manual homing screen. I didnt make her go any lower . . im scared she'll dig me a hole to my 3d printing grave... aughh..lol.

Ive tightened all her tinks and checked her guts and shes good as far as I CAN see. . . any ideas?

@Phaedrux you're my FAVORITE!

NOT MANUAL PROBING I AM HOMING.

fcwilt

Hi,

What version of firmware are you using?

Your config.g file configures a Z endstop - do you actually have one?

Frederick

gabrealek

Im running 3.2.0, as for z endstop, i installed a new one now, that was about a month or two ago. She worked perfectly up until today. I still manually home my machine from when my end stop was not responding.
That is why my homeall is setup the way it is.
This is my topic before when i got her figured out. Id scroll all the way down to the bottom

@gabrealek

I'm completely lost.

Is this topic your current problem?

If it is the first thing you need to do is update to 3.2.2 - 3.2.0 had issues with endstops in some cases. Those issues may or may not apply to you but if you update to 3.2.2 you will be sure to avoid those issues.

@fcwilt ok ill try . thanks

OK that rules out that firmware issue.

The position of the extruder assembly in the picture - that is the X min or X max?

Frederick

alankilian

Maybe your endstop stopped working?

Here's a LINK to a page that helped me test my endstops.

gabrealek

@alankilian @fcwilt the top picture is when it goes to max X, i looked in all my home files and i found that its at 305. i changed them all back to the 300 max. It does the same thing. Now its making more of the noise and pushing so hard its rocks the hotend. Im thinking maybe its the actual motor at this point but ill still test the endstops to be sure.

alankilian

@gabrealek If it doesn't stop when it hits the endstop then there is something wrong.

I bet you've checked all these things at least once, but it's good to try again since something is wrong.

Wire has come loose in the Duet connector
Wire has come loose at the switch
Switch has failed
Metal on switch has bent and the carriage is not pushing on it and causing the switch to operate.
Switch position has moved and is too far away from the carriage.
Configured wrong in config.g

gabrealek

@alankilian Yes i just pulled it out and the only light that is on is the X stop. I guess im going to have to re wire her completely. . this sucks.
thanks you all.

No, just follow the troubleshooting tips as you work your way through.

Try jumpering across the switch contacts and see if the Duet reads the switch opening and closing.
Look at the mechanical components.
Check your connector.
Jumper across the Duet pins

One thing t a time. You're pretty close I bet.

gabrealek

@alankilian they flicker on and off. i think my cords are stressed. im about to make a new chamber for the board and psu.

gabrealek

@alankilian im just now seeing this, im sorry. I've checked her through and through, once i moved my board the lights for the endstop would glow and then turn off. I think its the position i have it in. hopefully the cords aren't shorted out or worse. . everything on the inside looks pretty good though.

Phaedrux

Something is definitely off. In your photo it shows the print head moving to the right side when you pressed homeall, which is the wrong direction. Your endstops are on the left side and it's configured as such in the config and homeall.

Did the cables for the motors maybe get rotated 180 degrees? That would change the direction of the motor.

Just as a test to confirm, turn the printer off, move the print head to the center by hand, turn the machine on, send G92 X100 Y100 Z10 to mark all the axis as homed. Then use the jog buttons to test movement of the axis. X+ should go to the right, Y+ should move the bed forward. If it does the oposite, the motor got reversed either at the cable or in the M569 command in config.g
