Welcome to the SeeMeCNC Community

Problem solved thanks to assistance from DavidF. Turns out I had the x & y axes switched on the board.

Good to hear that its all fine now, I have been triple checking the wiring and connections :) I'd hate to go through all the pain.... What he said, where's the first print pictures :) Indeed lol :P And be especially careful when installing the peek fan as although I managed to do my first couple of ...

haha

no problem, glad to have helped. Funny on the ride home I was going to suggest re uploading the firmware. Maybe im getting better at my diagnosis.... haha Yeah, I thought perhaps it wouldn't hurt to reupload again. I've uploaded the firmware so many times I've lost count. It's funny how simple the ...

Oh, and thanks to everyone that tried to assist

I think your going to have to flip some wires around in thier connectors, I will have to look at things when I get home to see if there is some other way. Weird!! Setting the direction t/f should only change the motors rotation. But your saying you have to change directions to get it to go down ...

Likely the wires are in the connector in reverse order. Look at.the locating tab on the connector and note the wire colors, then compair to another connector. Hopefully you will see them in reversed order on the Y motor connector. If not you will need a dvom to locate each of the two coils in the ...

Unplug the x and y motors from the rambo and switch them. Was hoping to do it in the firmware, but I guess hardware swap it is! :D I'm computer illiterate LOL seems like its easier just to switch plugs than redefine the pinouts though LOL.. haha I know the feeling :P Well, it looks like you were ...

You said your y axis was grinding into the endstop, then when you hit the x axis limit switch it stopped? So the x axis never reached the limit switch???? Sounds like the limit switch wires may be flipped on the x and y axis, or the x and y motors are switched. That's why I wanted the belts off. To ...

While I'm thinking about it, are you sure your limit switches are correct for the axis they are on? I think you should pull all the belts, then tell it to home, then hit the one of the limit switches to make sure it stops the motor on that axis, do the same on all three axis....how about a picture ...

The fact you have your motor direction set false on one motor and true on the others should tell you something. Is this a rostock, or some other delta?? If the wireing is correct, then could you have a motor mounted on the wrong side of things? Yeah, in the firmware when uploaded it was originally ...

XY and Z max length should be about 360 ish. All positive. You do realize that positive most ion should be up right, and that once homed the Z position should be Z length. I've personally never used the LCD to set Z =0, but I do know it can result in negative values. Still the same damn problem ...

Just kidding and welcome Gnosis to the forum! It is great to have another member
from Australia.

haha Cheers, it's much appreciated

What are the heights set to? If you are sure the axis is moving in the right direction, but homing the wrong way, it might just be time to run the clear EEPROM program from the arduino tools and download a fresh copy of the firmware. Now that I've been messing around in with calibrating z height ...

It doesn't appear to have any negative values... Thanks though. Far out, it's nearing a week of the same issue.. ^^

Polygonhell wrote:I believe this can be caused by a negative value in the axis heights in the EEPROM

Hmmm... That makes sense. So, how would one go about changing a negative value to a positive value in the axis heights? Can it be changed in config.h or via the lcd?

I have had this problem from the outset. Every time I hit home it drives downward in the opposite direction of the end stops. I've calibrated the hot-end and heated bed, now I cannot go any further with this issue raring its ugly head. If I reverse axis direction, then the home direction is right ...

Speaking of the Wizard.. Pay no attention to the man behind the curtain!!

Thanks for the warm welcome

Ah yes, I noticed there are a lot of Aussies here, very good to see.

Haha I'll keep that in mind

Welcome. I am near Melbourne and am presently building a Rostock, slowly :) Bob Good meeting you m8. haha Nice, just finished building my Rostock :) Stuck on a homing issue atm, been stuck on it for three days with no clear solution in sight lol, yet I know when I find out it'll seem like it was ...
