Now, we did set Tools>Board:> Sanguino and Tools>Processor:>ATmega1284 or ATmega1284P (16 MHz). Now the problem is with step 4. It's not going to the center. This post from retrieval of existing settings, shows how: An example of the resulting file is shown in the question, Help with Repetier firmware variables (Dimension Dual Delta - J Group Robotics), a sample of which I have included below: However, you would appear to have to be running Repetier firmware for these two solutions to work, and not Marlin (but I may be wrong). To do this, there are basically two ways: Variant 1 would be to use the pre-supplied .hex files from Creality or some other manufacturer. -- | -- | -- | -- | -- It only takes a minute to sign up.

Homing XY moves to the lower left as it always has, but homing Z moves not only to Z=0, but also to the center of the build plate. Note that, if you cannot or will not flash new firmware, an alternative solution exists to set new incremental offset values using the M206 command IF your current firmware supports this. For best results getting help with configuration and troubleshooting, please use the following resources: After seeking help from the community, if the consensus points to a bug in Marlin, then you should post a bug report.

FYI for the OP: G0 is a rapid move, G1 is a feed move and you can program them with different rates, but a lot of 3D printers seem to treat them the same. X0 Y0 Z0 at this point. The hardest step with the Ender3 was to get the code to actually compile, as it uses an ATmega1284P 16Bit which isn't supported by Arduino natively. How to make Ender 5 use BLTouch probe for Z homing? what did you do besides mounting the bed leveling sensor? The working origin/print bed origin at 0,0,0 does not necessarily need to be the homing switch location. -- | -- | -- | -- | -- Can I safely add the Offset back just for the Z-Safe Homing to get a true Home Center the Bed. Z Safe Homing prevents Z from homing when the probe (or nozzle) is outside bed area by moving to a defined XY point (by default, the middle of the bed) before Z Homing when homing all axes with G28. Once I got those set so the nozzle was in the center while homing, I was able to set the probe offset in there and now the probe is nice and centered when homing. -- | -- | -- | -- | -- My sensor is 74mm in front of the nozzle and centered left/right. The issue I am having is when I do an AUTO HOME, the nozzle goes to the center of the print bed instead of the sensor. X | -- | -- | -- | --, Incorrect X/Y (0,0) due to z_safe_homing: Apparently there is an EEPROM editor available (in Repetier Host). It's the interpolation and X Y Z E microsteps that are moving the motors in a wrong way. Reddit and its partners use cookies and similar technologies to provide you with a better experience.

Not around a marlin so I can look up the exact lines, sorry. . News and information related to the Marlin Firmware used on many 3D printers around the world. This is for version Malrin-1.0.2. I did try to manually set the bed center position to no luck. What is homing? // When defined, it will: There are auto home buttons - but they don't home everything. in Marlin Firmware this is defined by. I still would like to find a way to slow down the X movement when it goes to home Z. This is resulting in run away X, Y, and Z movements. // - If stepper drivers timeout, it will need X and Y homing again before Z homing Why are parallel perfect intervals avoided in part writing when they are so common in scores? to your account. From How to make changes to the EEPROM data. Customized homing [safe_z_home] . Now the printer seems to be of two minds when it comes to finding the origin. the centre of the bed is not where Marlin thinks it is. What would cause that? Already on GitHub? (this was working before), When I do a G28, it correctly does the X, then Y, but now the Z is not done in the center of bed (I have bltouch) and the speed/noise from the Z axis is much higher. Well, let's start configuring our Marlin firmware to support BLTouch / 3DTouch sensors. My sensor is 74mm in front of the nozzle and centered left/right.

I do not have, you should possibly retract the filament before probing Z to prevent oozing. X, Y, and Z coordinates get assigned a value of 0. I think this is my issue. // - Block Z homing only when the probe is outside bed area. Was there anything changed recently on the Z_SAFE_HOMING? For more information, please see our Equipment: When homing the printer, the hot end carriage will be instructed to hit the (mechanical or optical) end stops. Makes me think something else is wrong there. Thank you so much. We did this with Z-Safe Homing did not like the nozzle on the corner of the bed. Note that if a probe is used, the offset of the probe to the nozzle center is taken into account, this implies that the probe is moved to the center, not the nozzle. Now on to getting the abl to work First attempt, the probe is off the bed to the side despite having the offset and margin set. -- | -- | -- | -- | -- Spellcaster Dragons Casting with legendary actions? // - Allow Z homing only after X and Y homing AND stepper drivers still enabled A detailed description to re-calibrate is found in answer How to center my prints on the build platform?

Adhesion issues with Ender 5 and BLTouch 1.3, Severe regression in print quality after adding Z probe, Weedo Tina2/Monoprice Cadet auto bed leveling: Sensor not moving down to touch the print bed. I thought I could have some edge value causing the firmware to ignore the -74 offset, so I adjusted this to -15 to test and see if the nozzle would be 15mm off of center. I have them detailed in my Marlin guide. While the MightyCore supports this chip, it doesn't compile with this hardware library. #define Z_SAFE_HOMING_Y_POINT Y_CENTER // Y point for Z homing Wow!

My information on the homing point relates to the nozzle, not the sensor. Creality offers the firmware on their website as a .hex file - which is hard to edit. Note that any arbitrary point on the heat bed can be used to re-calibrate this. I changed the homing points to 0. As I want to change to an e3D v6, which has a diameter of 22mm, I will have to move out some distance (ca. Sign in Could you expand upon your answer a little, by explaining what the additional code does and why it solves the issue? Hi, when i do G28 it Homes x and y but then the nozzle starts just moving down and not going to the middle of the bed maybe someone can help please. I appreciate any assistance I can get on this as I am not able to activate auto homing until the offset issue for the Y is corrected. Yes, this is because Repetier Host doesn't know where the extruder is. If you enabled Z_SAFE_HOMING, then automatically the printer homes Z at the middle of the build plate, if the bed size dimensions are correctly defined (in your case X_BED_SIZE and X_BED_SIZE should be defined as 300). I've set Z_SafeHoming. It should already have homing codes so just add in. This causes some issues such as now the nozzle wipe at the beginning of a print happens right in the center of where the print is supposed to be. Nice this did the trick. Seems like it would be a good idea to bullet proof this behavior in the firmware. So, in Arduino IDE press Ctrl+Alt+S (or Sketch > Export Compiled Binary). Connect and share knowledge within a single location that is structured and easy to search. During an AUTO HOME sequence, should the nozzle or probe be in the center of the bed if I have the offset set in the firmware?
