Corexy End stops and Home

recoush

MY CoreXY Setup
ramps 1.4 Full display generic, 8825 drivers
2 extruders bowden

2 1.8 80 oz motors and 1/32 step and 16 gears (400 steps)
3 0.9 65 oz motors z access 8mm tr2 screw (6400) steps (8825 stacked) fan on the stack

X & Y width is 550MM Max print area is about 500mm
Z travel is 660MM max
Using NO end stops with led
Keep in mind every thing top down CoreXY and the bed travels down when printing :>)

Seems Like home 0,0,0 should BE top / left Front for X & Y
and Z should be all the Bed should be all up stopping just short of the extruder end tip
will setup the z probe later

are the Min Considered Home End stops?
and max are as far the print area allows

MY home end stops are located
X and Y Top front Left ( is this correct read in one place Y is front and x is in back ?)
Z is just below X & Y triggered by the bed (just below the extruder tip)

Using NO end stops with Led see below they signal through ground and lit when closed
do i need?
The pullup True
hardware true

been playing manually with the end stops closing them and watching on M119
and it seems like the 2 above don't do any thing except cause more headaches.

I read some place that for the End stops being normally open they should be the MAX
should my home ends stops be wired to the MAX terminals
also there is no bump off when the NO is closed?

just realized these only work through the NO there is no NC wire only come with 3 wires
thanks

config h below
Got this working Now all end stops (home show) L when open and H when triggered they are in the Min Position
getting closer to a print.

is there a way to see the max end stops i have a z max endstop?
Z Max endstop does not show on the M119 report

Can move left right front and back and need to figure out why they wont move back, when it hits the end stops.

Just noticed when selecting X home x it moves (Y) home but is stutters (motor is trying to move Y but is already far left) and when homing Y it moves (X) home correctly even bumps back (this maybe due to repetier having X inverted in config as I verified that X and Y end stops are on X & Y Min

" is there a way to see the max end stops i have a z max endstop?
Z Max endstop does not show on the M119 report "

you have max Z endstop dissabled

#define MAX_HARDWARE_ENDSTOP_Z false

set this to true and it should show up with M119

Repetier

#define ENDSTOP_X_BACK_ON_HOME 1
#define ENDSTOP_Y_BACK_ON_HOME 1

might be a bit low for your endstop type. Test how much you need to go back to uncheck the endstops.

Ok so that seems to work decided to run a static print ( no extruder inplace and no filiment) the calibration cube.

my z axis that was homed. at the start of print, the Z axis is traveling (down) away from the extruder, some 230mm out of 660mm then stopped no X Or Y movemnt (nothing now) Zmax=660mm all the way down

noticed that manual could not move any of axis after doing the changes above hardware and back on home
bit they did home and back off

says idle and this is the last line
X 200 Y 200 Z 20.150 E:0.0000
which seems odd as x&Y did not move and z is at 230?

recoush

well after some more testing this is the working config, only one exception to get the x&Y working with home position have to have repetier host set to invert X

it will then home correctly, however if i home X or Y stutters then stops odd
Home works perfect
Z works

tried a print test cube
turn on extruder temp
start print goes to print then the gantry sits still while the screen fills then finish off extruder only issue is not moving the gantry while print is filling the screen sits in same spot ?

Repetier

Not sure what you mean by invert X in host but that has no influence on firmware.

Always check log with problems. If printer does not move firmware might have activated ignoring everything until M999 for an error reason.

recoush

Repetier: Not sure what you mean by invert X in host but that has no influence on firmware.
Sorry for the confusion that was in Repetier printer config :>) after several more config H changes no longer have to check that box.

For some reason my z end stop quit working, had been working on Z Min now min is the max end stop. Maybe the input is shot. Turned off all the min false and using MAX now all true. Very odd issue.
I am still trying to get X & Y end stop to work and move back, issue. See Below.
Perspective: Motors are in back as viewed from the front gears facing down and the belts and pulley are facing down, Extruder is facing the base plate.

My controls as viewed from the Repetier manual control:
X moves front to back
Y moves left and right
Z goes up and down

My home switches are X&Y left front side My Z end Stop is at the top with the base plate up=Home
eventually after get everything working will add the capacitive sensor

IF I chose to home X it homes Y, this is the same for Y moves X instead of Y
then x goes right and the Y goes back?

Maybe I am overthinking this but if X and Y and Z are moving correctly in manual as referencing Repetier controls.
inverting the controls has not really worked

Wondering if this is due to the Corexy being upside down I know other people have done this style and design.DO I have every else backwards and maybe in manual they should all be reversed?
Should left be right and back be front? Sorry for the delay in answers been traveling a lot and likely traveling again next week

Using this weakened to try and catch up and test
‘Recoush

recoush

Got it working i can home to left corner don't think X & Y are X & Y still think reversed. But that should not affect the z opeartion.

but it does home on Z X Y and does home all when choosed to ZXY

tried to dry run no extruder again, ODD thing when printing the cube the z axis starts down and keeps going down when it was homed at the top. stopped it half way about 400mm and then rehomed Z to the top

for some reason it wants to go to max distance or seems like it wants to go alll the way down to 660MM wondering if this specified someplace don't see anything about go this distance at slicer print for Z?

Repetier

You are a bit unclear so I can only guess that your z homing is completely wrong.
You said homing is bed at top touching nozzle, so that is z min homing.
You must therefor assign z max endstop (the one where you connected it to) to z min. Homing direction is -1. If this now goes to wrong direction invert z motor direction in config.

I think you have configured zmax to home to zmin position therefor everything moves wrong after homing.

recoush

OK will try that thanks

recoush

made the top Z min and the bottom 660mm down the Z max all the comments are identical for z min and Z max
but only z max with work the end stop home Z Min will stop z from moving if closed while Z is moving

these two were 9999 changed to zero
#define ZHOME_X_POS 0
#define ZHOME_Y_POS 0

these end stops are all Normally open and closed on contact see at the top what they look like.
these end stop wires are only 3 wire to the ramps 1.4 so NC is not used.

X & Y end stops hit and back off
But Z only back off on Z max

tried turning everything but Min Off no dice either, then none of the end stops work.

I think you should start more simplistic. Decide whcih endstops you want and use M119 to see endstop state and manually trigger them. If they trigger as expected continue with homing direction. -1 for z min homing and 1 for z max direction = away from extruder.

https://youtu.be/0XLRn5dpFa8<br/><br/>Having similar issue.
I think its the driver pots. My machines new too.
Driver pots
Steps per mm
Accleration
Feedrate.

Problem is is, if you dont have a proper steps per mm, accel and feedrate, how can you tune the pots.
So im thinking tune by touch but ive also had my motors do this at different volts so then its the steps per mm, accel and feedrate.

Just annoying.
In doing same as you, beating my head off the wall.
No one can give out a simple settings that works for your machine. Its stupid.

I bet people with exact same machine have checked this and couldve posted the fix but thought na let him do it hard way like I did.

I been asking for atleast 2months how to set mine up and just same crap, wrong settings sent and advice off people who dont got a clue.

A list with suitable setting for your machine is to much to ask for.

Wishing i had more time to work on this; Going to work on this again today. Think part of my issue is that there is nothing standard about my corexy setup other then the parts.

mine is XY axis on 12mm rails with pulleys this is a COREXY system i using system 1 with homing switches
this design has 3 Z motors with lead screws about 660MM high and 550mm for X&Y travel

the #17 stepper motors are set in the rear and are upside as are the rails.. made my left front as XY zero and Z zero should also be at the top as the bed moves up high at start then down because is is 660 up high to be near X& Y zero

since the motors and pulleys and rails are upside down i think in terms of the repetier manual screen , see photos below
those are equivalent to 1000g over each motor one time my 8 pound cat jumped on the bed did not have any issues with the extra weight cant imagine every making an 11 lb 3d part maybe someday

since there are 3 z motors installed 3 limit switches for one each z motor but i am having enough issues just getting 3 limit to home thinking of changing out my ramps 1.4 and 8825 drives for something note the pot lid is my extruder heat-sink until i mount it

May rework the gantry as my belt mounting system works but the belts dont always run parallel to the very ends
the extruder mount is designed for 3 extruders the z probe could be mounted there but is behind the mounting plate see the single hole for the zprobe today plan to try and figure out the homing limit switches have to see where i left off.

z always works the x or y is backwards and z home wants to travel down for some reason think that is where i was the last time. :>) really think there should be limit config too many setting in too many places, easy to lose track of where you left off last time. my steps per mm is ok it is these machinical limit switches driving me crazy just when i think i have it something else runs in reverse.

recoush

tried a lot of changes found that i had to download a fresh copy from the configurator, as my Y would not work until i loaded a new copy of Config H New Issue see below.

got xyz to home loaded the 20mm cube press print the Z access is headed down a lot, had top press the eStop?
how do i tell it Z is already in position at home?

it wont print with Z traveling down, any ideas?

Repetier

You must configure homing to always work even if you are already down. If you use a sensor that triggers only for z > 0 you can tell firmware to go up a bit before homing (at least in dev version) which solves such problems.

If the firmware is in laser mode, it can control a laser output to cut or engrave materials.
Please use this feature only if you know about safety and required protection. Lasers are
dangerous and can hurt or make you blind!!!

The default laser driver only supports laser on and off. Here you control the e??ntensity with
your feedrate. For exchangeable diode lasers this is normally enough. If you need more control
you can set the intensity in a range 0-255 with a custom extension to the driver. See driver.h
and comments on how to extend the functions non invasive with our event system.

If you have a laser - powder system you will like your E override. If moves contain a
increasing extruder position it will laser that move. With this trick you can
use existing fdm slicers to laser the output. Laser width is extrusion width.

Other tools may use M3 and M5 to enable/disable laser. Here G1/G2/G3 moves have laser enabled
and G0 moves have it disables.

In any case, laser only enables while moving. At the end of a move it gets
automatically disabled.

If the firmware is in CNC mode, it can control a mill with M3/M4/M5. It works
similar to laser mode, but mill keeps enabled during G0 moves and it allows
setting rpm (only with event extension that supports this) and milling direction.
It also can add a delay to wait for spindle to run on full speed.

Repetier said:

well it does home to zero, but for some reason when i say print it wants to drop too far below the extruder by about 300mm or more never stops?

my thought was to make Z min Zmax (since x,y and z home are all at or near the top of the baseplate (0) at Z home. and put z min at the bottom about 660mm below X,Y I suspect the same issue.

maybe test on Wednesday, test z min and Z Max
Z min does home to zero and bump and move away form the stop.
think i need a stop at each end of Z to prevent damage to the Z travel.

RAyWB

just from looking at your machine :

if you move your bed close to extruder to home its ZMIN
if you move it away from extruder it´s ZMAX

so if your endstops are at top of your machine thex are zmin endstops
if they are at bottom of your machine it´s zmax endstops

from your configuration:

#define Z_HOME_DIR 1

youre homing to zmax , so endstops should be located at bottom of machine.

if your endstops at top of machine (i guess they are there) change to

#define Z_HOME_DIR -1 (that´s homing to zmin)

and invert motors direction

recoush

Ok will give that a try, think that is the way i have it wired now (looks like i have to change z home dir (thanks)
will try and do a video next time have someone to help take the video

while i was driving was pondering this i remember, still have the z probe to install. (replaces Z min? )
have to do some research as i have read many variations on its use and wiring
