Help Needed Printer Printing Wrong Size

I Have Had All Kinds Of Problems With Homing And Axis Ive Rewired The Printer Totally.

Two Problems I Have:

1. When I Connect To The Printer Via Computer And Try To Move Axis (Any Axis) It Wont Move Manually I Have To Click Each Axis Click Home For Each Axis Or Home For All Axis
At Some Point An Axis Will Move Then All Axis Will Move.

I Can Work Around This But Would Like To Understand Why It Happens.

The Other Thing Is The Main Problem I Have Now Is The Printer Prints The Wrong Size..

While Printing A Bush The Printer Prints It 10 mm X 40 mm Instead Of 20 mm X 30 mm

Im Thinking It Seems Like 10 mm Is Being Taken From The X Axis And Added To The Z Axis Im Not Sure If This Is The Case

Im Not Sure If Its To Do With Slicing Or To Do With The Printer.

Im Using PRUSA i3 Printer

Ive Attached A G.Code File If Someone Could Print It To See What Size It Is I Would Be Greatfull

Cant Attach File Its To Large If Someone Could Message Me I Could Email The File

Thanks Haydn

use pastebin for the code.

When the machine is powered on it defines that position as 0. Normaly on I3 type machines It will not go into negative from position zero.

To redefine position 0 you home the axis, or manually tell the printer where it is at see G92:_Set_Position

I suspect you still have issues with your endstops..

send the printer a M119 command (endstop status) it should be the same as the machine really is... ie all open if no endstops are triggered, and as each end stop is hit its will reply that that axis is triggered.

scaling is more likely to be your steps/mm are wrong.
Send to printer a M503 command (display settings)
Take a look at the M92 line

The number are for x,y,z and e

most machines should be 80 for x and y if you have standard hardware

Hi Bit Of History Bought This Printer 2nd Hand It Worked But Couldn't Get It To Stick To The Bed
Sorted That And Everything Was Fine
Then The Printer Tried Going Past Enstops
Then Printer Started Printing Wrong Size
Rewired Printer Then Manual Movement And Homing Is Fine
No Problems With Enstops
This Was A Chinese Kit With Melzi Board And The Person I Bought It Off Transferred Settings From Melzi Config To Ramps And Arduino Mega 2650 Config
So Home Is Set To X 0 Y 0 Z 0
This Is Mechanical Settings

Movement Seems To Be Fine If I Move It 100 mm In Pronterface Or Repitier Host It Moves Almost The Bed Center
Seeing The Bed Is 205 mm Print Area This Seems Right

Im Reluctant To Change Settings As I Dont Have A Fresh Firmware Anywhere Near Ok Yet.

I Have Configured Slic3er For My Printer

Thank You Haydn

You have listed your end stops status twice, but given no information what the machine was doing at the time

But even then the MAX endstops should not always be triggered

Presuming you only have min endstops on the left, back and down positions you should disable max endstops

ie find

//#define DISABLE_MAX_ENDSTOPS
//#define DISABLE_MIN_ENDSTOPS

change to

#define DISABLE_MAX_ENDSTOPS
//#define DISABLE_MIN_ENDSTOPS


M92 looks fine for normal type hardware.

If the top set are when X Y Z endstops are all 'not'pressed and the bottom set are when all endstops are pressed, then you have the endstop logic settings reversed.
When no endstop is pressed, M119 should report all as open

Hi Sorry Should Have Made It Clear
First One Is After Homing So All Enstops Are Pressed
The Enstops Are Wired NC And Comomon

The Firmware Is Marlin V 1.0.2

I Dont Have A Copy Of The Firmware Only A Copy For The Melzi Board That The Lad Took The Settings From For Arduino 2650 And Ramps 1.4

I Cant Update The Firmware As I Dont Have The Original And I Dont Think The Disable Enstops Option Is Available In Marlin V1.1.0
Was looking For M Or G Code To Change It. The Eprom Option Is Set So Settings Can Be Saved

I Have Tried Configuring A Version Of The New Marlin But Have Run Into Problems With The Hot End

If I Define Thermal Runaway Protection ( Remove Comment Dashes )Then I Get A System Halt Message In Marlin 1.1.0-RC8 Before It Reaches 185 Degrees

If I Disable Thermal Runaway Protection ( Put // Comment Slash In ) It Reaches 185 Degrees But Smells Like Its Burning

Not Sure What Is Causing This Not Sure If Its Cause Marlin V 1.0.2 Configuration Is Different Than Marlin V1.10 RC8

Here Are Both Configuration Files

Thanks For Your Time And Help

Haydn

In marlin v1_0_2 cnfig.h

// The pullups are needed if you directly connect a mechanical endswitch between the signal and ground pins.
const bool X_MIN_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.

const bool Z_MAX_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
//#define DISABLE_MAX_ENDSTOPS ; <<<<<<<<<<remove // on this line
//#define DISABLE_MIN_ENDSTOPS

Yeah I Dont Have The Original Firmware The One I Posted Is Only The Config For The Melzi Board If I Try To Compile It In The New Arduino IDE I Get Lots Of Errors
Ive Managed To Change Steps Of X And Y To 80 Using Repitier Host And Saving Eprom Settings
Ive Tighened The Y Belt Just In Case But Still The Same

There Is Something Changing The Size Not Sure What Its To Do With But The Printer Prints Great

I Dont Think Its To Do With The Max Enstops Cause It Printed Fine Till This Error Appeared

Not Sure If Its Slicing Problem Or Setting In The Printer Firmware Or Software But tried Slicing And Printing From SD Card And Still The Same

Heres Log Of Print From Repitier Host

Thank You Very Much For Your Help I Am Greatfull

Haydn

What version of Arduino are you using to compile marlin with,the later version do have compile errors with marlin.

I use arduino 1.6.8 with no errors.

Allso what type of Z axis does your printer have, Threaded rods or Lead screws, and what size ?

Edited 1 time(s). Last edit at 01/02/2017 04:22PM by obewan.

Hi Im Using Arduino 1.6.12 I Do Have Arduino 1.5.? On Another Computer

The Z Axis Is Standard Prusa Two Steppers One Either Side Of X Axis Moving The X Axis Vertically

Screw Is Lead Screw M8 That Goes Through Center Of Stepper No Couplings Not Sure Of Pitch But Looks Twice That Of Standard Threaded Rod

Wouldn't Of Thought It Would Be To Do With The Z Axis As That Only Effects The Hight

If Any Axis It Would Be The X Or Y Axis

However Whatever Is Going On It Must Be Affecting Both X And Y Axis As The Piece Is Printing Round Not Oval Just Smaller

Ill Find A Computer Wipe It Clean And Install Repitier Fresh With No Settings Just To Illiminate Any Software Problems When Slicing

Thanks A Lot

Haydn

Ok Wiped Computer Clean And Tried Printing Part Slicing With Default Settings Still The Same So Must Be Something In Firmware

Thanks Im At A Loss And Drained It Does Not Make Sense

Haydn

Ok So I Have Solved Part Of The Problem But Still Got A Problem With The Z Axis

Measured X And Y Axis Moving 100 mm But Was Only Getting 80 mm Turns Out That The 78.74 For X And Y Axis Needs To Be 98.425 Strange

So Now That The X And Y Is Printing Correct Size Z Axis Is Still Printing To High.

I Was Convinced That The Bush That Should Be 30 mm Diameter By 40 mm High Was Going To Be Fine When I Corrected The X And Y Axis.

But No !! It Is Still The Same The Z Axis At The Moment Is 533.33 Which Is Strange Cause What I Have Is A NEMA 17 Stepper 1.8 Degrees With Standard Pitch M8 Lead Screw.
So Im Thinking 200 * 16 / 1.25 = 2560 If Im Wrong Please Tell Me Someone Please

This Does Not Work For 100 mm Travel I Get 86 mm Actual Travel

Tried Changing Things On Z Axis But Everything Goes Wrong The Print Moves Between Layers.

Thinking The Speed Could Be To Fast

Ive Attached Picture Of Repitier Firmware Config Showing Printer Settings

If Anyone Knows Why This Could Happen When Everything Was Working Ok With The Original Settings Id Really Like To Know

Im Really Eager To Learn All I Can Then Mabe In The Future Ill Be Able To help Others

Thank You veRy Much

Haydn

Screen Shot Didnt Work But this Does See Attached File

You probably have a multi start leadscrew.
Look atvthe end of the leadscrew, it probably has 4 starts on it, so divide your steps/mm by 4 (2560/4=640)
set your Z steps to 640 should sort it.

for X and Y what pitch is the belts (tooth - tooth) What diameter is the pully on the motor and how many teeth on the pully

Hi That Sounds About Right Will Try That Im Not Sure Of The Stuff As I Bought It Second Hand.

But I Know The Belts Are GT2 And GT2 20 Tooth Pully

I Really Want To learn About All This Stuff And Im Quite Good When I Understand How Things Work

Just Sometimes Things Dont Make Sense Like Im Thinking That The Old Settings Worked Fine But Then Changed

So Im Thinking There Must Be A Common Denominator That Affects All Axis To Knock Them Out As It Has

Ive Been Building A Small Printer For My Daughter To Have A Play With

Everything Is Working Fine Just Need And Extruder Ill Probably Buy One For Now

But Anyway On The X And Y Axis They Both Have The Same Stepper Motor, Belt And Pully But Y Axis Is 80 And The X Axis Is 83.??

Im Not Bothered Cause I Am Able To Adjust It Perfect But What Causes Two Exact Same Axis Setup To Be Have Different Settings ?

Id like To Understand Other Things That affect The Settings Like On The Above X Y Axis Example

Thank You Very Much I Feel Better Knowing About The Lead Screw Will Try That In the Morning

Thank You

Haydn

Hayden, Happy New Year. Your posts are more difficult to read than they need to be because you capitalise each word. Reading is a very fast function based on pattern recognition. Having each word begin in upper case makes the reading much less fluent. The people who have posted replies above have done an excellent job and.have worked hard to understand the problem you have with the printer. If you have upper case only for the first letter of sentences, and for other places where significant, it would help readers to see the problem more easily.

I'll get my tin hat

Ok its a habit i suppose related to programming. I will stop it lol

thanks
haydn

Hi Obewan tried your suggestion started at 640 ended up at 410 but at least its printing to scale now

Think Ill get printer i built for my daughter printing then ill pull this one apart adn rebuild it with a new frame

its strange cause the one i built behaves as exspected.

i have tried building a new firmware for this one and think im ok with the mechanical settings but get problems with hot end

cant get past 180 degrees not sure why

anyway thanks for your help
