Could you expand upon your answer a little, by explaining what the additional code does and why it solves the issue? I did try to manually set the bed center position to no luck. 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. In order to use z safe homing the X and Y axis must be homed. Software: A detailed description to re-calibrate is found in answer How to center my prints on the build platform? The Home position is about 1mm left and 2mm in front of the front left corner. -- | -- | -- | -- | -- This implementation supports only a single extruder. 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. there is a way yo activate the called "safe homing" which allows you to home in any x and y point. Privacy Policy. Then when I home the Z axis the bed moves to the center of my print bed (90,90) and does it Z probe. The 3 point auto leveling was working intermittently and the GRID auto level would appear to home, but would not center the probe in the bed. Unfortunately, the same issue is still happening. I needed to edit the steps/mm for the x/y axis. 2. I just got my Ender 5 Pro set up with a Bigtreetech SKR Mini E3 v2.0. How To Use a PC Power Supply With Your Printer!

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. No matter what I try, X goes flying whenever it goes to home Z. If i only do it after G29 While setting the probe up, I've watched countless tutorials and haven't had any luck. #define Z_SAFE_HOMING #if ENABLED(Z_SAFE_HOMING) #define Z_SAFE_HOMING_X_POINT ((X_BED_SIZE) / 2) // X point for Z homing when homing all axes (G28). Although its after G28 and not G29 :). Anet A8 with original mainboard v. 1.5 The printer knows this is (100,100,0) and is not mistakenly thinking it is (0,0,0). Nice this did the trick. Almost there with my settings, I am now trying to find a "non macro" solution to this issue: I am using sensorless homing, so homing_retract_dist is not an option, now, when Homing XY or Homing All, I would like the X axis to move by 10-15mm after "hitting" the virtual endstop, to prevent him of flirting with the Z axis rods and ledscrew support when travelling his way to home Y. How to determine chain length on a Brompton? 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.

The text was updated successfully, but these errors were encountered: So if you run G29 does it try and start probing the middle of the bed first? 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). #define Z_SAFE_HOMING_Y_POINT Y_CENTER // Y point for Z homing Wow! Now open the Marlin.ino in Arduino IDE. Now, we did set Tools>Board:> Sanguino and Tools>Processor:>ATmega1284 or ATmega1284P (16 MHz) It was also mandatory to have the U8glib.h for Arduino installed. Eventually, the 3 point . To prevent the Z endstop on a Voron 0 from triggering while the first layer prints, it's good practice if the Z endstop is positioned such that the nozzle ha. I use the safe z homing but have never had this problem. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 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 occasionally send you account related emails. My nozzle hit the bed pretty strongly on my first try (the bltouch still triggers the Zmin if I do it with my finger) Here are my configuration . You can close it. privacy statement. Spellcaster Dragons Casting with legendary actions? Should the alternative hypothesis always be the research hypothesis? Seems like it would be a good idea to bullet proof this behavior in the firmware. There are auto home buttons - but they don't home everything. I'm the happy owner of a smoothie5x and I'm trying to figure out how I can edit the firmware to make the print nozzle home to the center 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. Please Help going nuts! With this I don't believe I need to use the M502 and M500 commands. Okay so it may not be a bug with Merlin but rather with Repetier host. -- | -- | -- | -- | -- The philosopher who believes in Web Assembly, Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI.

Set up the new firmware with these base settings or adjust as needed. I tried setting absolute values here, I've tried doing ((X_min_pos + X_max_pos) / 2). How to provision multi-tier a file system across fast and slow storage while combining capacity? I'm closing (remove if possible), then you have to describe the problem correctly. I even attempted to set the offset line to the same format of the examples { 0,-74, 0 }. You signed in with another tab or window. `` Add M114 after G29 to pull the coordinates back to RH. X&Y axes home (fore some reason the X axes des not do the second slower homing procedure, I don't know if it's related) Kind of annoying, as you can imagine. With a G29 command, the sensor is off the front side of the bed and the nozzle is where I want the sensor to be. This will result in two files: Of these two, the Marlin.ino.sanguino.hex is the interesting one for "direct flashing" via CURA. And yes, Arduino supports this. Now, we did set Tools>Board:> Sanguino and Tools>Processor:>ATmega1284 or ATmega1284P (16 MHz). I have been printing with my Anet A8 for years now. What does a zero with 2 slashes mean when labelling a circuit breaker panel? G28 Z0 ; Home Z. I believe that should accomplish what you're after. Many thanks. Was there anything changed recently on the Z_SAFE_HOMING? In your Configuration.h, line 1390, your homing is set to center. We did this with Z-Safe Homing did not like the nozzle on the corner of 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. Note that any arbitrary point on the heat bed can be used to re-calibrate this. Sci-fi episode where children were actually adults, Review invitation of an article that overly cites me and the journal. It should already have homing codes so just add in. one from Christian, a German maker also known as "Chaos-Drucker"), we need to first adjust them as needed to fit our needs and then compile them properly (next step!). G0 X100 Y100 F6000 ; Go to X100,Y100 at 100mm/s The idea of Z safe homing is that it is forced to home Z in the middle of the bed (bed size/2) so the inductive probe does not try to trigger in thin air. It is usually configured to do something like x/y bed size, divided by 2 to put it in the middle. Did you hook "Origin is in center"? In the later case, you need to put the folder Marlin-?.?.X.ZIP/Marlin-?. Cool that works as advertised. I followed multiple threads on this issue but not a single one solved my problem. However, Christian did figure out that the Sanguino set to an ATmega 1284P 16bit does work. I do not have, you should possibly retract the filament before probing Z to prevent oozing. According to Repetier Host it runs on Marlin 1.0. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA.
