<![CDATA[SoliForum - 3D Printing Community — Press Firmware patches?]]> 2015-02-08T16:24:42Z PunBB https://www.soliforum.com/topic/9547/press-firmware-patches/ <![CDATA[Re: Press Firmware patches?]]> Oh, I should also mention, to use them:

M99 X0 Y0 Z0;    //Set Backlash correction amount
M98;                   //Print Current Backlash Correction amount


for Example, I put the following in my Start code for RH:

M99 Y0.3;

These are my notes...  hopefully they are clear.  The info was gathered from a post in another forum here, the author's original post on Google groups, and from the SD2 Github repository.  I've included the files I got from the solidoodle 2 github repository.

Step 1. In marlin_main.cpp, after the other includes that are already there...
 
#include "Hysteresis.h"

Step 2:
In marlin_main.cpp, Search for the lines:

    #ifdef ULTIPANEL
        case 0: // M0 - Unconditional stop - Wait for user button press on LCD

and add the following line prior to the #ifdef line:

    DECLARE_HYSTERESIS_MCODES(98, 99)

Step 4. In planner.cpp, after the other includes that are already there...

#include "Hysteresis.h"

Step 5. Insert a line in the plan_buffer_line function in planner.cpp. It should be the first line in the function, before "int next_buffer_head = ...."

hysteresis.InsertCorrection(x,y,z,e);

Step 6. Add the attached files (hysteresis.cpp and hysteresis.h) to the Marlin directory

That being said there is no reason you couldn't use Adrian's latest fork of marlin on github.  Just make the necessary dimension changes for the press and enable the appropriate hysterisys patch.

I was specifically wondering if a version could be compiled to support the Hysteresis/anti-backlash mods ( https://groups.google.com/forum/#!topic … Nnym1MC94Y ) that were made to Marlin at some point in the past (now deprecated).

I would really like to be able to print proper circles, and I don't see a way to adjust the tension on the Y axis, other than the short belt that connects to the stepper.
