Homing problems #147

Closed wildBill83 closed 12 years ago

wildBill83 commented 12 years ago

I have been trying to get quick home (home both x and y at same time) to work, is this currently supported or still developmental?

Also when homing, my printer only hits the end stops once, even though in the firmware I am telling it to retract and slowly home after hitting the end stop. Am I the only one seeing this behaviour?

wildBill83 commented 12 years ago

bkubicek, I haven't been able to ever get it to work in any version. I'll post my config.h when I get home. I think it has to do with non-standard end stop configuration.

Hardwarekiller commented 12 years ago

I have the same Problem See # 145.

And no reaktion of my Post !

bkubicek commented 12 years ago

quickhome is fixed now.

muffinman00770 commented 12 years ago

Sorry bkubicek but i get exactly the same issues as wildBill83 (quick home fails (not that I am concerned) and there is no home retract).

I think your Marlin is brilliant (i have tried several others)

bkubicek commented 12 years ago

So exactly, can you post your configurations files? What is your machine? What kind of enstops do you have?

muffinman00770 commented 12 years ago

My machine is a Reprap Prusa Mendel with wades extruder running (Arduino Mega 2560 rev3, RAMPS 1.4 (Arduino Mega Pololu Shield), pololu stepper drivers (Pololu A4988)).

OK.

All Versions from Marlin include the Version from Apr 12 2012 works ! After this Version works Home NOT correct This Version have 2 Bugs !

Normaly must work

  1. If I have an axis X or whether X or Z in the host software to go home then drove towards end stop. Once it has now hit the end stop, the axis stops short, then the axis moves a little back from the end stop away, and goes back to the end stop, and then stops.

This Bug-Version make If the axis is driven home to them is just standing there and drives do not return shortly, and again at the end stop

2 If the axis is already at home and now I press the Home button, the axis normal to make the same as when I come from a different position, which makes them not!

This Bug-Version make If the axis is already at home and I press the Home button then ride the short axis NOT the end stop off and back on it but, the stepper motor makes them very short little steps towards home, and that every time I use the Home button actuated

It is NOT the way to the Configuration, since even if there is nothing he does makes the wrong Since its release on 15 April changes were made​​, the problem has occurred. The version dated 12 April and earlier worked flawlessly all

bkubicek commented 12 years ago

in git, you can download individual states after commits. please try the following commits: a) https://github.com/ErikZalm/Marlin/zipball/67cf105bc69c555547d1c2ba1974b03a2a2c70c3 this one should probably work

b) if it as you say, this one is most likely not to work: https://github.com/ErikZalm/Marlin/tree/67cf105bc69c555547d1c2ba1974b03a2a2c70c3

c) if you have a non-workign set: does the problem still occur, if you change the home position to i.E.

define X_HOME_POS -10

define Y_HOME_POS -10

define Z_HOME_POS -10

muffinman00770 commented 12 years ago

Thanks for the great response! a) - no change in operation (still no retract when homing and quick home (x and y axis at same time) fails to work (yes i have uncommented #define QUICK_HOME)

b) improves situation: quick home is successful when uncommented (#define QUICK_HOME ) AND no longer need to comment #ifdef ULTIPANEL when using ramps #define MOTHERBOARD 33 - this problem was not listed but now no longer needs a workaround :D (//#ifdef ULTIPANEL) BUT still no retract when homing

c) changing the home position makes no change in operation (when as set as above)

define X_HOME_POS -10

define Y_HOME_POS -10

define Z_HOME_POS -10

bkubicek commented 12 years ago

muffinman: That is very very difficult to debug. You guys state that the version before 12.April worked. I send you a link to this version, a, and you tell me its not retracing, although its from 12. april. That does not fit together.

have you changed something in the configuration_adv.h? somewhere close to

define X_HOME_RETRACT_MM 5

define Y_HOME_RETRACT_MM 5

define Z_HOME_RETRACT_MM 1

?

muffinman00770 commented 12 years ago

Hey bkubicek :-),

I have never said 12 April version works (the version I am currently playing around with is (ErikZalm-Marlin-v1.0.0.RC2-98-ge4d2138).

The only setting that i have changed in configuration_adv.h is uncommenting #define QUICK_HOME (retract did not work with it either commented or uncommented.

Here is my configuration_adv.h file for you to look at (if you need to that is). I do appreciate your help (I have been talking to one of my mates about the issue and he is having a look into it as well (another programmer)).

Could it be something to do with an error in the actual marlin code:

define HOMEAXIS(LETTER) \

if ((LETTER##_MIN_PIN > -1 && LETTER##_HOME_DIR==-1) || (LETTER##_MAX_PIN > -1 && LETTER##_HOME_DIR==1))\ { \ current_position[LETTER##_AXIS] = 0; \ plan_set_position(current_position[X_AXIS], current_position[Y_AXIS], current_position[Z_AXIS], current_position[E_AXIS]); \ destination[LETTER##_AXIS] = 1.5 * LETTER##_MAX_LENGTH * LETTER##_HOME_DIR; \ feedrate = homing_feedrate[LETTER##_AXIS]; \ plan_buffer_line(destination[X_AXIS], destination[Y_AXIS], destination[Z_AXIS], destination[E_AXIS], feedrate/60, active_extruder); \ st_synchronize();\ \ current_position[LETTER##_AXIS] = 0;\ plan_set_position(current_position[X_AXIS], current_position[Y_AXIS], current_position[Z_AXIS], current_position[E_AXIS]);\ destination[LETTER##_AXIS] = -LETTER##_HOME_RETRACT_MM * LETTER##_HOME_DIR;\ plan_buffer_line(destination[X_AXIS], destination[Y_AXIS], destination[Z_AXIS], destination[E_AXIS], feedrate/60, active_extruder); \ st_synchronize();\ \ destination[LETTER##_AXIS] = 2LETTER##_HOME_RETRACT_MM \ LETTER##_HOME_DIR;\ feedrate = homing_feedrate[LETTER##_AXIS]/2 ; \ plan_buffer_line(destination[X_AXIS], destination[Y_AXIS], destination[Z_AXIS], destination[E_AXIS], feedrate/60, active_extruder); \ st_synchronize();\ \ current_position[LETTER##_AXIS] = (LETTER##_HOME_DIR == -1) ? LETTER##_HOME_POS : LETTER##_MAX_LENGTH;\ destination[LETTER##_AXIS] = current_position[LETTER##_AXIS];\ feedrate = 0.0;\ endstops_hit_on_purpose();\ }

stohn commented 12 years ago

Hello,

I spent last week to get my old JTAG ICE MKII working with Arduino1280+RAMPS14. It was a real pain to get Arduino and Marlin to compile and work in AVRStudio5...

...but now I'm able to use a proper development environment with hardware breakpoints and easy debugging.

Today I spoke with hardwarekiller about his problem and after a short debug session we found the problem mentioned in this thread (maybe it also is a solution for other people with similar problem.

Symptom: Homing was not working properly - In fact the retract never happend.

Problem: In "PINS.H" the "X_MAX_PIN" / "Y_MAX_PIN" / "Z_MAX_PIN" been defined (this is Marlin default) and "X_ENDSTOPS_INVERTING" / "Y_ENDSTOPS_INVERTING" / "Z_ENDSTOPS_INVERTING" was set to false.

==> BUT THERE WERE NO ENDSTOPS CONNECTED TO X_MAX / Y_MAX / Z_MAX

==> The endstop for X/Y/Z max was ALWAYS signalled ==> No retract

Solution: Check your "pins.h" and set X_MAX_PIN / Y_MAX_PIN / Z_MAX PIN to "-1" to disable the endstops in case your machine does not have endstops connected.

Hope this solves the problem for others as well.

Maik

BTW: I found some programing mistakes/bugs in Marlin firmware with AVR-Studio (e.g. it is not a good idea to have a static variable of a class which initializes a lot of hardware inside of the constructor -> "MainMenu". This showed a lot of problems in AVRStudio during startup. Better call a dedicated INIT function from either setup() or loop() - AFTER Arduino library did their own initilization).

wildBill83 commented 12 years ago

I will try that. Any chance this enables dual axis homing?

Hardwarekiller commented 12 years ago

Now ist Works !

Thanks !!!!

Hardwarekiller

bkubicek commented 12 years ago

so, to tidy up, as far as I understand, this is not an issue of the marlin code, but a configuration problem. I will hence close this issue, if there is furher trouble, please feel free to reopen it. all the best, bernhard

muffinman00770 commented 12 years ago

THank-you all who helped fix this problem i very much appreciate it :D

Muffin

wildBill83 commented 12 years ago

setting X_MAX_PIN / Y_MAX_PIN / Z_MAX PIN to "-1" did not solve my problem. Individual axis homing works.

Any fix for dual axis homing?

wildBill83 commented 12 years ago

I have the pins.h set that way, it enables the correct homing. I still need to resolve dual axis homing.
