Marlin Firmware Upgrade 1.1.0 RC8 & RCBugFix (For R1 & R1+PLUS)

@Lary post number one has direct links to the current versions. Because of a bug yet to be corrected in Marlin post RC8 there are currently no versions newer than RC8

It is a Z limit switch not working.

The the Z only goes up that is invariably the issue.
The firmware will NOT allow the Z to go down if it thinks Z is home. Either of the switches being triggered is Z HOME

 

I have not forgotten about his firmware. The main contributor is away for a needed rest since early January and there are now 42 pull requests in the queue for RCBugFix. So there will be no new builds that I am working on until his return and the pull requests are merged with the existing code. So please continue using RC8.

I will try to have a version of RCBugFix as soon as he returns even if it doesn't fit with my schedule of having something on the 1st and/or 15th of each month.

 

For all the people waiting for an update, myself included; it looks like the main contributor is back and is merging in pull requests after moving to a new residence. Nothing added yet that is of any interest, but I will try to have a new set of files on the 15th/16th of this month.

 

Here are the files for Marlin 1.1.0 RCBugFix as of February 15, 2017. I have separated them out into several compressed archive files. Just download the one you need and extract the appropriate files within the Marlin source subdirectory. You cannot use configuration files from previous Marlin releases or from previous Release Candidates. These archives contain the complete source modified as noted. This version and future versions of Marlin must be compiled on Arduino IDE 1.6.8 or newer.

Basic steps required:

1. Download one of the attached files appropriate for your hardware
   RCBF_ABL_R1_02-15 for Robo R1 with 8 mm Z Axis threaded rods
   RCBF_ABL_PLUS_02-15 for Robo R1+PLUS and R1's upgraded with the Z-Axis lead screw upgrade kit from Robo3D
   RCBF_ABL_TR8_02-15 for Robo R1's with upgraded Z Axis 3rd party lead screws
2. Compile and upload to your Arduino 2540 board using the Arduino IDE. Compilation has been tested with Arduino IDE version 1.8.0 only.
3. After successful upload, clear EEPROM memory by issuing the following two commands in terminal mode:
   M502
   M500
4. Re-enter you Z axis offset using M851 as a positive number. M565 support is not supported in this version

Common to all these files are:

1. Set up for Hexagon hotend
2. Full Graphics LCD enabled
3. EEPROM memory enabled
4. Automatic Bed Leveling enabled w/16 probe points (4 x 4 grid)
5. BILINEAR bed leveling enabled as default
6. Major performance improvement for Graphical LCDs
7. Some other stuff

New - Sorting options for file list available in Configuration_adv.h. See section called "SD Card Sorting options".

Please note that I am not one of the Marlin developers. If you have an issue with this release post here first. If it is determined that it is not a configuration issue, then you may be directed to post the issue on Marlin's GITHUB. I cannot guarantee success using beta firmware, I can vouch for error free compiling with these included files. If there are issues with the configuration let me know and we can work on them together. Original post (#1) edited to provide a link to RC8 and current RCBugFix files.

This version and future versions of Marlin must be compiled on Arduino IDE 1.6.8 or newer.

Basic steps required:

1. Download one of the attached files appropriate for your hardware
   RCBF_MESH_R1_02-15 for Robo R1 with 8 mm Z Axis threaded rods
   RCBF_MESH_PLUS_02-15 for Robo R1+PLUS and R1's upgraded with the Z-Axis lead screw upgrade kit from Robo3D

3. After successful upload, clear EEPROM memory by issuing the following two commands in terminal mode:
   M502
   M500
4. Re-enter you Z axis offset, if needed, using G29 S4 Zn.nn, where n.nn is the amount of offset from the bed. M565 and M851 support are not supported in this version of Marlin.

Common to all these files are:

1. Set up for Hexagon hotend
2. Full Graphics LCD enabled
3. EEPROM memory enabled
4. MESH Bed Leveling enabled w/25 probe points (5 x 5 grid)
5. Major performance improvement for Graphical LCDs
6. MESH adjustment heights configured to prevent fractional micro-steps

@Ed Ferguson
I think its in a pull request but the code hasn't been merged yet.

It looks like there was talk back in November 2016, but little to no movement since then.

 

So, I flashed MESH and started playing around with it. The LCD is so much smoother than before and more responsive and the outline fonts save a lot of CPU cycles that are used now to print. I haven't played with the Alpha Sorting on the SD card as I rarely print from the SD (I use OctoPrint almost 100% of the time). So far I haven't found any real issues. I do think that using 0.04 mm stepping for the MESH adjustment might be too fine, I won't change it unless others think so also.

I think now that the Marlin contributors are back on track I can start to focus on other projects.

One last question, it is very easy to make a .hex file of each version and then you could upload a new firmware with MatterControl or OctoPrint (requires installation of avrdude and the Firmware Updater plugin). Might make it a bit easier since the .hex file is already compiled.

Just download the 8 mm set of files and you only should need 2 line changes. In Configuration.h look for this cluster of lines

Code:

//#define DEFAULT_AXIS_STEPS_PER_UNIT   { 80, 80, 2267, 800 }  //--BH Default steps per unit for RoboR1 5/16" Threaded Rods
#define DEFAULT_AXIS_STEPS_PER_UNIT   { 80, 80, 2560, 800}  //--BH Default steps per unit for RoboR1 8mm Threaded Rods
//#define DEFAULT_AXIS_STEPS_PER_UNIT   { 80, 80, 800, 800}  //--BH Default steps per unit for RoboR1+PLUS
//#define DEFAULT_AXIS_STEPS_PER_UNIT   { 80, 80, 400, 800, 800}  //--BH Default steps per unit for RoboR1 TR8*8

Take the first line in that group and remove the //, take the second line and add them to the beginning. In the end the first two lines in that group should look like this

Code:

#define DEFAULT_AXIS_STEPS_PER_UNIT   { 80, 80, 2267, 800 }  //--BH Default steps per unit for RoboR1 5/16" Threaded Rods
//#define DEFAULT_AXIS_STEPS_PER_UNIT   { 80, 80, 2560, 800}  //--BH Default steps per unit for RoboR1 8mm Threaded Rods
