Solved Homing Y Issue

Printer: Robo 3D R1 *RESOLVED*


*Freefloating Cord to heatpad was incorrectly ziptied backtogether*

First few prints worked with nearly no bind noise whatsoever, however; upon the end of the second print when the program Cura moves Y tray out to easily remove the 3d print, it makes a binding noise. So anytime I go to home x y and z, my x homes and hits the toggle switch to stop, y does not stop binding the motor unless I turn it off, is there a way to predefine my home offsets? Also I have the dimensions 228 254 228 for build volume. I also had been reading about making sure belts are correctly tightened and etc.

 

Make sure you do not have machine center 0,0 checked in cura.

 

Thanks for the reply, Mike. I do not have these setting(s) checked. Also this is happening in MatterControl as well as Cura. It seems to be a home configuration error. If I even make my X axis go away from origin to it's maximum stop, it seems to do a "slight" grinding. However; the Y axis seem to get worse as time went on because I set the Y axis to home and it ground initially for a sec and stopped (when it occurred first that is) and now it just wants to hang forward unless I power the machine off, which I always do to avoid any damage to the motors and or gears.

 

I have the same problem in MatterControl if I use the manual home movement controls, it starts the print and my Y gets stuck grinding, so I no longer use the home controls. can you post your settings in cura for your gcode.

 

Additionally, underneath the heated bed, there seems to be a limit switch. It looks just like the one for my x axis, however; there is nothing on my machine to hit this button as it extends and even if it did, I pushed the switch in when I was making y adjustments and it continued; maybe there is a problem with this switch? What's weird is my initial prints had no problems. The second print or third print is when the machine sequenced the end code to tell the y axis to move out of my machine(easier access to the 3d design) and it did a slight motor grind, but I didn't think anything of it at the time. Yet on the next G28 sequence(x-y-z origin) the y axis continued until powered off.

This is what I was told and it works perfect

G21 ;metric values
G90 ;absolute positioning
M82 ;set extruder to absolute mode
M107 ;start with the fan off
G28 ;Home All
M565 Z-.6 ; Define 1.0mm of offset, adjust this value if you're too high/low. More negative is further from the bed
G92 E0 ;Reset Extruder count
G1 E-3.0 ;Retract 5mm for probing to limit dots
G29 ; Run autolevel routine
G1 Z15.0 F{travel_speed} ;move the platform down 15mm
G92 E0 ;zero the extruded length
G1 F200 E3 ;extrude 3mm of feed stock
G92 E0 ;zero the extruded length again
G1 F{travel_speed}
;Put printing message on LCD screen
M117 Printing...

 

Also my G28 is edited, I was trying to play with the Y home to avoid the grinding.

 

Yeah I've used that exact code for all the prints, aside of the leveling of the Z axis, because mine is perfect @ 1.0 instead of .6. Still grinding the Y axis when homing.

 

Looks like he edited his OP saying a wire was getting caught.

 

glad you got it worked out. Print on.

 

Thanks for the help guys. Yeah it was just the free moving cable to the bed getting hung up. Got it all set and it's printing flawlessly. I searched for days before buying to get the perfect cura settings; and now that it's running, time paid off.
