MARLIN 1.1.0 RC3 adapted for G2/G2S PRO

[phervier]

I have made a specific Github repository to keep a version of the Marlin firmware specifically adapted to the Geeetech Delta printer.

This version is a fork of the last stable stable version of Marlin. It has already all the settings ready for the G2S printer. It can be found here :

     Gitub G2S version

To install it on your GT2560 board you only have to :

• Download all the marlin directory to your computer and put it in your Arduino repository
  
• open the marlin/marlin.ino with the arduino IDE
  
• Change or verify a few things in the configuration.h file (it is the only file to modify) :
  
  • verify the number of extruders
    
  • verify the thermistors used (by default the Geeetech one is set)
  • verify the geometry of the printer if you are not using the metal spider (the settings are for a PRO version)
    
  • change the MANUAL_Z_HOME_POS value to the height of your printer (as written in the Geeetech manual)
  • change the language you prefer with LANGUAGE_INCLUDE
    
• Compile and install the firmware on the board.
  

Almost all other parameters may be changed and stored in EEPROM without any recompilation.

This version differs from the main version of Marlin mainly with the settings of the parameters and the correction of a few bugs. But it also include some harmless modifications that I found useful for current use. Bigger or risky modification will be made in specific branches of this version.

The improvements on this version are :

• Functional function for auto levelling G29 (but you may have to modify your hardware see the specific thread)
  
• Parameters ready in configuration.h to calibrate tower positions with this link  calibration of delta printer
• Direct command of Ledstrip (complete description in an other thread)
• Modification of the calibrate LCD menu to allow :
  • direct choice of the final height between 0 and 10mm by 0.01 increments
  • 7 points of calibration directly accessible by the LCD menu without the need of any computer or repetier-host
    
• Improvement of the G30 command (Single Z probe, probes bed at current XY location) to include repeatability tests with new parameters:
  •  I : number of iteration for repeatability computations compute mean height and difference sigma
    
  •  C : print steps on each tower at each z_probe stop
  •  Q : divider for the speed of final z_probe approach (from 2 quick, to 50 very slow)
    
• ad the Q  parameters (choice of final test speed) to autolevelling
  

These modifications are included in the version of today (14 march 2016).

Others modification may be also included in further versions

This version has been compile and tested on a Geeetech G2S PRO version and should work gracefully however I can not guarantee its use on any other printer. Use it at your own risk.

This is great! Thank you! Sorry for the noob question but, I ran all 7 calibration points directly from the LCD menu, and I get the nozzle off the plate at different heights in each different point. How do I make adjustments so the nozzle is at the same height in all points?

Thanks!

This is normal before the calibration process here is an example : plus.google.com/+JasonMcMullan/posts/h9EC1nG9xeu

I've compared the configuration.h files between the stock/Geeetech version of the firmware, and your adaptation of the 1.1.0 RC3 firmware.  I understand most of the changes, but there were some areas that differ that I did not understand.  One question I have is if these are changes you made, or changes that might have been made between the Geeetech version, and the 1.1.0RC3 version.  

I've put them in a table below:

Settings	Old/Stock	New
Thermistor	#1 (100k)	# 14 Geeetech (100k)
Heater MINTEMP	5	10
Heater MAXTEMP	275	255
PIDs	#define DEFAULT_Kp 22.2 #define DEFAULT_Ki 1.08 #define DEFAULT_Kd 114	#define DEFAULT_Kp 12 #define DEFAULT_Ki 0.49 #define DEFAULT_Kd 77
PIDTEMPBED	//#define PIDTEMPBED	#define PIDTEMPBED
Bed PID(?)	#define DEFAULT_bedKp 10.00 #define DEFAULT_bedKi .023 #define DEFAULT_bedKd 305.4	// HEATER BED and glass plate GEETER #define DEFAULT_bedKp 159.62 #define DEFAULT_bedKi 31.28 #define DEFAULT_bedKd 203.61

Thanks for any clarification or advice!

changes on min/max temps were made by me, because 275 can result in melted tube insert in hotend.

PID are specific for each printer, and should be calibrated for specific parts/mods made during calibration, using PID auto-tune command in repetier.

new values are easily imputed in printer menu or in FW.

[phervier]

The thermistor 1 is for the semitec one. I did not change this thermistor table but added a new one (at number 14) for the genuine geeetech one.

The Heater mintemp is the temperature under which the system detects a problem of thermistor and halts. I thought that nobody would print under 10°C

Thanks, guys, for the additional information.

Philippe Hervier - I was wondering if you've seen the recent RC updates from the Marlin project, and wondered if it would make sense to update your G2S release with the RC version updates: github.com/MarlinFirmware/Marlin

[bobo67]

Thanks Philippe Hervier, i use your firmware version and work super fine!
Do you think to release the RC6 version?
I've already adopted the Configurator.h of PC6 and work fine (compiled with Arduino 1.6.0), only if "i enable the auto bed leve define" i've some error...

[neildarlow]

That is unlikely to work well. There will be changes between RC3 and RC6 which are not in Configuration.h.

To be complete you need to isolate all of Phillipe's changes to RC3 and see if they are still relevant to RC6. This can be done with a clone and merge operation if you are familiar with Git.

This is on my job-list once my G2s Pro is running well with RC3.

[bobo67]

I've already create a 1.1.0 RC6 version for my Geeetech G2s Pro with some fix for the "size and angle correction", not well implemented (imho) in the previous 1.1.0 RC3.
Follow the thread i've created on Google+.
Cheers...

Buenos días como podría agregar la opción STEPPER_HIGH_DELAY en esta versión de firmware.

hey there

really interesting.. was planning on uploading the firmware.. but i bumped into an issue.
take in account i'm working on ubuntu linux.. so this might play a part in the issue.

1) downloaded the zip file and tried to extract.. but the zip file could not be read. tried the download again. same issue.
2) tried downloading and extracting it on my android tablet.. worked fine.
3) took sd card out.. put it in the laptop and tried to cpoy it to the sketchbook.. which it did.. BUT little icon measuring how far the copy was. got stuck around the 80% while data wise (amount of mb) was complete.
4) tried compiling it.. compiler error.. missing marlin.h, this while marlin.h was opened and readable, tried again.. to no avail.

as said, ubuntu here. could be the issue. but just felt it to be my duty to let you know anyway. for now i'll stick with the standard firmware but i stay interested.

I have this version installed on my G2S Pro and I built and uploaded it on fedora.

Maybe you had a problem during downloading the zipfile and it got corrupted in the process.

Can you try cloning the repository with git or try the later version referred to a few posts back in this thread.

[zuzu]

can someone post link for adapted g2s pro fw ,i can't find it on google plus board
and if it's possible to show how to adapt that g2s pro fw to single ev3 extruder
thanks
