Topic: x axis homing to left?

so I just got done installing the upgraded linear bearing carriages that lawsy posted up.
now for some un known reason my printer wants to home x-axis to the left.
and even if I put the micro switch on the left it doesn't reach the switch to engage it. it travels the full distance it is suppose to but doesn't even come close.

did I miss something with this upgrade?

I have the MK5 extruder installed.

help please printer is out of commission till I figure this out. and I already some how broke the top part on the right side y carriage that the pull pin goes into.

im kinda frustrate.
anyone have any ideas what I screwed up?

Re: x axis homing to left?

If you did not change any settings in RH... then make sure you plugged the stepper in the right direction(if you had it unplugged)...

Re: x axis homing to left?

And check to make sure the belt connection (to the extruder) is on the proper side...

how would that make a difference.

maybeing im just not understanding it but I didn't think the belt being flipped would reverse directions.

I didn't un plug the motor.

Not in front of my SD right now (and not even sure it's possible), but I mean the connection point of the carriage to the belt...the belt is a loop. If the carriage is connected to one side of the loop vs. the other (front side vs. back side), then direction can be reversed...

You have the carriage on backward so the belt is flipped. The belt is pushing when it should be pulling

so I should take the extruder assembly off and literally slide the x-axis carriages off turn them and slide them back on?
of course un mounting the belt first.

see I thought it was backwards but I couldn't find any pics of the underside that told me anything.

Re: x axis homing to left?

You could do it that way or since you have to disassemble it any way. Just pop the bearing holders off the bearings and switch them. That's what I would do.

apparently Im dyslectic when it comes to belt direction.
I get it now.

thankyou for the help,

lol now I need to print a new right carriage after I change the direction since my is broken.

I guess I can chock it up to a learning experience.

Don't you just hate it when you take the time to do something like this and you miss something simple that screws it up?

Re: x axis homing to left?

Glad you got it figured out

Just for info... if you switch the motor pole sets of wires on a stepper it will reverse direction... however I do not know if the plugs on the SD's controllers are wired symmetrically and would do this... I have never flipped them or even looked at the wiring order with this in mind.

You can and the motor works fine but wouldn't that mess with the end stop logic?

Re: x axis homing to left?

yeah so the bearings are total crap.
efin china made pieces of.....

I even oiled them.

so now what?
where I travel they are loud as all hell.

so all that time put in for nothing?

Probably I haven't looked at the code in f/w either, I know you can set it up in EMC2 as that's what I use in my bigger cnc stuff.

Even the so called good ones are less than perfect. They may be loud but how is the movement?
They will over time create a groove on the rods and should loosen up. Did you replace the rods also or just add bearings?

fixed the bearing problem, just had to stop whining and figure it out. lol

so I am for sure out of commission till I get that new hot end.
damn thing wont print worth crap.

but one thing im noticing though is,
the nozzle is level to the bed at a stand still, is sitting perfect off the bed to print but when it goes to print it is lifted just enough off the bed so its as if it is printing in the air.

what would cause this lift?

In your slice profile you have Z-offset at something other than zero.

ill check an see if I can find it,
but how would I have accidentally changed that?

it dosnt seem like the z screw is moving any though.

hmmmm.

*****edit: offset is at zero.
would it be something to do with the y axis belts not being aligned with each other?
if that's the case I have no idea how to correct that.

Re: x axis homing to left?

The Y-axis belts have nothing to do with whether or not your bed moves properly. Look at your start G-code and see what's in there for Z movement.

Re: x axis homing to left?

I don't think his bed is going down. I think the extruder body is moving upwards.

Re: x axis homing to left?

I think the hotend is moving up and down, so what the filament is pulled up the hotend moves a hair up and is causing this.

so I just printed a test box. I have no idea what is going on now.
it turned out perfect.

bah.....
