0,0 is (should be) the front left corner of your bed. 350,350 is the back right.

#

Therefore, I'm a little suspicious when I see

# 
points:
   320,310
   -320,310
  -310,-300
   320,-300

i was under the impression 0, 0 should be in the middle of the bed with tap

empty perch
#

No

zinc tendon
jade acorn
#

om sounds good once i get that changed it should correct the issue right, or is there a different issue

zinc tendon
#

If thats adjusted see what QGL does

Could be that u have to manually level the gantry

jade acorn
zinc tendon
jade acorn
#

ys

zinc tendon
#

If not, please follow that

jade acorn
#

yes

#

it just says center of the bed

zinc tendon
#

Ok so enter the middle points of your bed

jade acorn
#

ok so with the default probing points its only probing the top right quadrant of the bed

#

where IS 0,0 right now?

jade acorn
#

ope

#

middle of the bed

#

how do i move it

empty perch
#

you don't in the direct sense

#

how big is your bed

jade acorn
#

350 mm

empty perch
#

and are your X/Y motors 200step/rotation or 400 step/rotation (aka 0.9 degree)

jade acorn
#

200 steppers

empty perch
#

honestly? I don't believe you

#

if they're 400s, it just explains why all your moves are currently half length a little too nicely...

jade acorn
#

they are set for 200

empty perch
#

oh I know they're set for 200

jade acorn
#

how do ik if they are 400 steppers

empty perch
#

read the label generally

#

sometimes might have to extend out to reading a datasheet or something

#

is this an LDO kit?

jade acorn
#

yes the rev c version

empty perch
#

ldo ships 0.9 degree motors for x/y

#

so 400s

jade acorn
#

oh

empty perch
#

(as seen in the sample ldo config you posted too)

jade acorn
#

hmm

empty perch
#

that'll be your problem

#

fix that, and 0 will go over where it belongs

jade acorn
#

when i put it together i thought i copy pasted the config my fault

empty perch
#

the voron stock file is set to 200, since it's mostly just ldo that does the other

#

I'm guessing you took that particular line from the voron one, or from some other source

jade acorn
#

ahhhh that would explain it

#

um so now its qg leveling really weird in a lmost diagnol pattern

#

i can send a video if that would help

empty perch
#

sure

#

include homing too if you would

#

tends to help spot...things...

jade acorn
#

no problem

#

i did the homing again and x is crashing into the endstop switch as it goes back im pretty sure thats got something to do with minimun values though?

empty perch
#

no

#

it's far more fundamental

#

X and going back do not belong in the same sentence

#

X is a left/right movement

jade acorn
#

hold on let me send a video

empty perch
#

ya, so you've got two problems there

#

the first problem, is that it shouldn't be moving back at all. it should be a clean move to the RIGHT

#

I suspect that you have the wrong pulley on one of the X/Y motors. they're supposed to be the 20T, but I suspect you have at 16T on one of them (which belongs on a z motor)

#

the second problem, is that it should STOP when it hits the right hand endstop

#

did you test your endstops before you started trying to home?

jade acorn
#

yes the endstops should work fine before i changed it to 400 it was working perfectly

#

it would home fine without this issue

empty perch
#

strange

#

but... time to test it again

#

if you press the endstop switch on the LEFT side of the pod, what endstop does mainsail show as triggered?

jade acorn
#

both of my endstop switches are to the right

empty perch
#

your switches should be on a pod on the underside of the gantry joint

#

and one of them should be on the LEFT side of THE POD, such that it faces the toolhead (if it was on the right, it would be up against the panel)

#

and the other should be on the back of the pod

jade acorn
#

yes correct

#

let me check

#

showing correct x triggered

empty perch
#

hmm. OH

#

I see

#

watching the video again, it did home X successfully, and then moved on to trying to home Y,

#

the y homing is just extra problematic because it's trying to drift farther to the right

#

so I take it back

#

just one problem

#

the drifting on the axis its not trying to home

#

and I still believe that is probably an incorrect pulley

jade acorn
#

this voron worked perfectly at one point i had to scrub everything because it got corrupted so i dont think its a pully

empty perch
#

well, let's see your config as it stands now, I guess

jade acorn
empty perch
#

ah

#

x and y are 0.9 degree

#

you only updated X

jade acorn
#

oh fuck did I

#

oh i changed it on the extruder thinking it was y

#

ok its fixed

#

now to figure out the qgl

empty perch
#

I just saw X Y and Z there, no qgl

jade acorn
#

QGL works now

#

also is there a way to move my tool head up a bit when it moves from pos to pos its dragging on the bed a little

empty perch
#

that's the horizontal_move_z setting

jade acorn
#

set at 1 thinking about 3 or 5

empty perch
#

where ARE you getting these settings from?

#

I don't know of any stock config that sets it that low

jade acorn
#

the QGL settings i found from the voron forums

#

because it was doing some other weird things before

empty perch
#

that was a poor choice. you should put qgl back to stock

#

I suspect that's part of somebody's more complex multi-pass qgl setup

#

which is fine, but... you have to understand it and setup the whole thing. taking half of it is...problematic, as you've discovered

jade acorn
#

I see that now its returned to stock

#

is there any bed mesh code you recomend thats what im moving to work on next
