Marlin for Mosaic

[Rick Pollack]

marlin configured for mosaic. this is an older version of marlin but it has worked reliably. once you are comfortable with 3D printing you can upgrade or just wait for us to post a newer version.

Is this different than what was on the shipped Mosaics?

[Gary Kramlich]

I got my mosaic about 3 weeks ago, and yes it is.  I loaded marlin to get end stop supports.  It's working well :)

Sorry for stupid question but what is Marlin for? google don't help.

I am new to 3D printing so I am afraid I am missing something.

Marlin is the "firmware", the main program that you need download to the arduino board. (In MG products is pre-installed, normally) 

The two most used firmwares that you can found in this "3Dprint-world" are: "Sprinter " and "Marlin".

Marlin is newest and has some improvements. Sprinter has been used by a lot of users and is really tested.

With this version I got heavy shifting.

I switched  to ErikZalm-Marlin-v1.0.0.beta1-0-g5535e51 and shifting stopped. 

However I constantly get this:

Error: checksum mismatch, Last Line:9

Resend:10

Error:No Line Number with checksum, Last Line:9

What do I do wrong?

Here are some diffs for Mosaic m1.  Not tested with latest Marlin, but I'll fork and test as I go.

The 'Mosaic m1' changes/settings (from diffing to github.com/ErikZalm/Marlin/) Configuration.h
//line 14, this is in the same place as in the version ric posted
#define MOTHERBOARD 33 // RAMPS 1.3 = 33

// Previous
//line 33
//Mosaic
float axis_steps_per_unit[] = {87.489, 87.489, 251.96,1420};
//line 88
float max_feedrate[] = {200000, 200000, 250, 500000};
float homing_feedrate[] = {1500,1500,120};

// Current, now defined differently, changed for Mosaic M1
// line 211
//// MOVEMENT SETTINGS
#define NUM_AXIS 4 // The axis order in all axis related arrays is X, Y, Z, E
#define HOMING_FEEDRATE {25*60, 25*60, 25*60, 0}  // set the homing speeds (mm/min)

// default settings

#define DEFAULT_AXIS_STEPS_PER_UNIT   {87.489, 87.489, 251.96,1420}  // default steps per unit for Mosaic m1

#define HOMING_FEEDRATE {25*60, 25*60, 3*60, 0}  // set the homing speeds (mm/min)

When you first connect with the host software you should see something like this:

Connecting...

start

Printer is now online.

Is there a way to check what version of firmware I'm currently using?

[NCBob]

You can also enter M503 and it will re-display this information if your firmware supports M503 :)

[Eric]

changed version to  add M1 display.

added:
       #define MSG_BUILT_DATE_TIME "Built: " __DATE__ " " __TIME__

and then to setup
  SERIAL_ECHOPGM(MSG_MARLIN);
  SERIAL_ECHOLNPGM(VERSION_STRING);
+  SERIAL_ECHOLNPGM(MSG_BUILT_DATE_TIME);
  #ifdef STRING_VERSION_CONFIG_H

which produces:

When I connect mine just says "start".

Is there another way to tell.

By the way is there a link to instructions on how to update the firmware?
