I am not a programmer just a mechanic and I have pulled most of my hair out trying to get this to work but can,t     Please help

Thank you Hazer 

Teensy Loader, Command Line, Version 2.0
error reading intel hex file "Marlin.cpp.hex"

If you missed it, renee just posted a fix for this:

http://www.soliforum.com/post/53271/#p53271

I followed your link to the wiki  and did a test run up to
the part where I entered cmd line     I typed in  ;

hid_bootloader_cli -mmcu=at90usb1286 -w -v Marlin.cpp.hex

hit the enter key

and got this 

Teensy Loader, Command Line, Version 2.0
error reading intel hex file "Marlin.cpp.hex"

I did not have the MB plugged in to the usb cable for this test for fear of something going wrong
and not being able to use my printer at all.

I am using Arduino 0022 from the wiki page

  Thank you for your help       Bill D.

or use a programmer on the ISP port, like a usbtiny.

This is what it says after trying to upload

This with the T3P3 branch of Marlin they sent me to via a link

Hi my name is  Bill  I recently got SD 3   and tried to add T3P3 Panelolu2  but have had issues would you be inclined to help?

Not sure I can be of much help but if you post what you're experiencing I am sure somebody will be able to.  Ive just been able to figure out what I need by reading the source code.

Nice stuff - will have a poke around myself a bit laters..
Did you consider using the M600/M601/M602 mods that would otherwise offer similar functionality ?

Yes.  In fact i used the M600 code for reference when adding my pause/resume changes.  However, the M600 code primarily handles filament changes and seems to be meant for imbedding those changes at specific places in a print, I wanted to extend the concept to be fully interactive with an LCD (even without a PC) and work with any axis so a similar operation could be used at any point an operator noticed a clog/shift/break problem in a print.  I was surprised after seeing the M600 code that the pause/resume menus did not reset the current e-position in the same way, since one of the most common reasons for pausing a print is presumably to change the filament.

The feature that I think is most potentially useful, however, is the "Resume from SD" menu I added, which essentially automates the process of measuring the z-height and splitting up a cgode file at the right place when needing to resume a partial print.  That's normally a pain to do, especially when printing files from an SD card with no computer handy to edit the file. 

The intention was to make the process much more like resuming a DVD, where you can simply back up to where you last were and hit "Play" to resume.  As a bonus, since the code still processes the non-motion codes in the skipped part of the file, any temperature or other settings should be restored, which wouldn't occur if a gcode file were simply started in the middle.  I might have missed a code or two, but I used it last night to resume a print that stopped midway from a clog and I found it super convenient.

I'm going to continue to add any ideas I find interesting, and the code may be a little raw, but here is a zip of my modified source so far and the changes:

Major:

1) RESUME_PRINT_FROM_ZLEVEL

This menu option lets you start a print from and SD card file, but any axis-homing commands and all motor and extruder movements below the current z level are ignored.  I use this feature to "resume" a print that stops printing due to a clog or broken filament.  I just manually seek the head down to the exact top of the partial print and "resume" the same file I printed originally.  It heats up normally but jumps past all the printing code until it reached the right z-level, then continues where it left off.

The code internally just sets a "floor" z level.  I image you could add a gcode command to set this level to a specific value or from the current z-level so that this would work for PC-based printing as well.

2) PAUSE_AND_HEAD_UP

This extra pause menu conveniently drops the bed a preset amount after pausing to allow for nozzle cleaning with a drill bit.  Importantly, I changed this and all pause menus to save the current axis positions immediately after pausing so one could seek back to that position later (more below).  The move-z menu is automatically activated after pausing to allow for additional adjustments.

3) PAUSE_AND_RETRACT

Similar to above, but retracts the filament after pausing to prep for a filament change.  The move-extruder menu is automatically activated so the new filament can be fed in.  I lengthened the timeout value before control goes back to the main menu due to inactivity.

4) RESTORE_LAST_POSITION

When printing is paused, this menu seek all three axes back to the saved positions, even if you've manually moved the head around.  This is useful to have as a separate option in case additional manual adjustments are needed, such as dropping the head down a bit to make up for layers that failed to print.

5) RESUME_FROM_LAST

Combines the above menu with a normal "resume" menu to continue printing after seeking to the last position as above.  Importantly, I changed the "resume" menus to compensate for any extruder moves.  Previously, I would find after resuming a print that the gcode would try to "undo" any manual filament feeding I would do after changing filament.  This seemed unhelpful, so I added the compensation.

6) RESUME_FROM_HERE

This replaces the normal "resume" menu, but add offset values, if needed, to fool the printer into thinking it hasn't moved from its saved pause position.  This lets you make adjustments in any direction to compensate for a shift or gap and still have the rest of the print line continue from where you tell it.

Minor Changes (probably not of general interest):

a) Added a custom welcome message

My LCD always said "Welcome Mendel" instead of "Welcome Solidoodle".  The existing code looked correct, so I don't know why it was wrong, but I wanted to customize the message anyway.

b) Custom cooldown function

The previous cooldown menu used gcode  but only cooled the extruder.  I don't know why the bed temp wasn't also set, but I changed this to a function to explicitly set everything to 0 and that seems to work better.

c) Flattened distance menu

I never liked the extra step of having to select a movement distance since I almost always wanted 1mm movement.  I put both 1mm and .1mm options in the same menu and lost the 10mm choices.

d) Preheat Safe temp

I added a menu to allow preheating the bed, but only warming the extruder to 80 degrees so it wouldn't burn the ABS if I left it in this state for a long time.

e) Prehead ABS menu

I don't print in PLA, so I took those menus out for now for me.

f) Reverse encoder direction

The thumbwheel control with my LCD controller turned in the wrong direction (clockwise for up and counterclockwise for down) so I added a switch to optionally reverse the direction.
