Figuring out Marlin to work
September 06, 2020 02:36PM
Hi Guys!

I'm new to the 3D printing world, and trying to get make a printer of my own :-)
So, I purchased all necessary electronics and mechanical parts, and now am trying to figure out the software.
To do so, I uploaded the Marlin(1.1.9.1) firmware onto my RAMPS 1.4 board.

For testing the software basics before getting the components into the structure, I am testing with the following components.
Arduino Mega
Marlin (1.1.9.1) //without any modification
RAMPS 1.4
Nemo 17 4.2 Kg motors
Pronterface

So after loading the firmware and connecting to Proterface,i try to place Y to 10 places from now(G1 Y10 F1200).
But there is no actions going on with the motors and the printer shows this up in the Arduino terminal :


Connecting...
start
Printer is now online.

This is the same situation i am in rather what command I pass.. I don't know if this is a stupid question or not!!
Suggestions from you guys are appreciated big time...<3

... check your configuration for pins, directions and endstops ...

*** EDIT *** -- are your motors powered? (harder to turn when enabled)

Test machine is actually doing commands send a M119 (show endstop status) to the machine. Does it reply?

Steps per unit also seem to have pretty weird numbers between x and y.

What kind of machine is it. Would you have images of the wiring and maybe the config files?

@Dust Thankyou for looking into this.

I tried passing M119 which gives me the following results.-

SENDING:M119
Reporting endstop status
x_min: TRIGGERED
y_min: TRIGGERED
z_min: TRIGGERED

@Ohmarinus Thnkyou for having a look into this.

I am trying to build a custom 3D-Printer of my own. And i have been testing with only the boards and motors connected to X and Y(Noting else is connected like endpoint triggers or thermistors).
And the config file i used are from Marlin(1.1.9.1) without any modification(PFA).
The steps per unit is defined as "#define DEFAULT_AXIS_STEPS_PER_UNIT { 1600, 80, 4000, 500 }".

Looking forward for your replysmiling smiley

@VDX thnkyou for the insight!

yes the motors are powered and can you like suggest any recommended values for the same?
Re: Figuring out Marlin to work

Config file you provided has
#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 4000, 500 }

also
#define Y_ENABLE_ON 1
unless you using very non standard stepper driver hardware this should be #define Y_ENABLE_ON 0

This would stop Y moving.

Hi Dust,

I've made the changes on Y_ENABLE_ON as zero as below

#define Y_ENABLE_ON 0

And tried again, still getting the same response ie the motor and Pronterface doesnt respond on passing G1 Y10 F1200.

I see you have enabled INCH_MODE_SUPPORT

so G1 Y10 F1200. is really G1 Y482.6 F1200.

F1200. is 20mm sec so that is going to take 24.13 seconds before it comes back with an OK.

But that doesn't solve why its not moving.

What are you using for stepper drivers?
Can you provide a image of how you plugged in the stepper drivers into the ramps.
Do you have 12v power to the ramps ?

Dust , we are using a 12V supply to power the RAMPS and been using A4988 Stepper driver.
Attaching the snippet of the connection

Just some advice, never run an axis without a stepper motor connected!

... without stepper connected is not the problem -- much more: un-/plugging while powered!!!

"12V supply to power the RAMPS" there are two power plugs the 5amp and 11amp circuit



Which did you power up? the steppers are on the 5amp side.

i think i hsve connected the right one(the 5amp side).

Is there any way that we could identify ifthe problem is with the software\firmware side or with the hardware side ? Attaching the snippet of connection i made which has only one Motor connected to Y and passing Gcodes to move Y axis.

Can it be the problem that there are no endstops connected? I believe you also need to connect endstops in this case or else the machine will think that the axis has run into the endstop and not allow motion if it keeps being seen as triggered.

I would run the ramps testing firmware [reprap.org]
No need to edit anything. just compile and upload

This just moves all stepper motors back and forth and turns all mosfets on and off..
Is a good way to tell if it is a hardware or firmware issue.

It this moves the steppers, its not hardware.
