Solved ROBO3D R1 BED LEVELING

Hi everyone i just bought this 3d printer used and ive been watching all the videos and reading all the posts on the subject i am using simplified 3d software to run the printer and a robo 3d r1 with autoleveling profile so it puts the auto leveling script in at the beginning of the print but no matter what i do when it runs the first the first line around the perimeter of the part never fail it does not adjust for the bed being un level and since there are no leveling screws on the print bed at all i cant get it to come even close to making a good first layer i even went as far as putting a double pc of paper under it when it was doing its autolevel at the beginning of the program and still the tip ends up touching the glass on one side of the print job its almost like its not compensating for the bed at all

any ideas

You forgot the part about manually turning the motor on one side or the other to help straighten the X-axis relative to the Y-axis when doing this.

 

ok so do i do this with the machine off?? and this is just manualy adjusting the 2 screws ???

 

and my start up block looks like this

G1 Z5 F5000 ; lift Z by 5mm

G28 ; home all axes

M565 Z-1.1; set the offset for auto-leveling mechanism

G29 ; run auto-level

M300 S440 P200 ;A4: 440

G0 Z5

 

ok so to make sure im doing this right first i start up the machine home the machine this puts the tip right on the glass
then i turn the machine off and turn the screw so i can get a pc of paper to just slide under then machine still off slide the axis to the other side and adjust that screw the same way but what about front to back that is were my problem is it prints nicely in front but rubbs the glass in back

 

is there a better script i should be using

 

yes its not off by very much at all but you can see it when it goes through its autoleveling

 

i can see using the paper to adjust the level of the 2 z axis screws in X but how do i make the adjustment i need in Y there is no leveling screws on the bed at all

 

The latest version of the custom firmware @WheresWaldo has been keeping documented for everyone is generally held to be the best upgrade you can do on your R1.

Marlin Firmware Upgrade 1.1.0 RC8 & RCBugFix (For R1 & R1+PLUS)

I know it's not a Gcode script, but during the very short lifetime where my R1 was functioning the Mesh Bed Leveling back around RC6 made it actually reliable about printing objects without screwing up the first layer.

 

Most people put paper shims between the magnets in the bed to adjust Y-axis relative to X, if they don't decide to say "screw it" and update to the custom firmware in the thread in my other post.

 

OH ***** i had no idea the bed was held down with magnets and ill work on updating the firmware ive never done this before so it might take me a little time to figure out

 

ill have to get back to you guys later this after noon i have to go get some work done first but now i have a place to start

thanks

 

OK i dont know what ive done but now when i try to home the machine it just moves a tiny bit in y from were ever it is
and does not even move to the limit switch an yet it calls that home and the end stops do not stop the movement in y or x when it hit them
if i turn on the machine and give it the command of g28 it goes from were ever its at and moves to what it thinks is the center of the table even when its not and makes that x0y0z0
