Z sensor is a inductive proximity sensor. marlin has a default offset for the probe, so you should set them to 0 both. 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 other possibility is the probe config is wrong so the probe is not where marlin thinks it is. I found it. By default the values were X_Center and Y_Center. Already on GitHub? In order to use z safe homing the X and Y axis must be homed. Although its after G28 and not G29 :). When you change the hardware (e.g. Can dialogue be put in the same paragraph as action text?

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. Last edit at 11/14/2018 07:44PM by . (G28) #define Z_SAFE_HOMING_Y_POINT (Y_MAX_LENGTH/2) // Y point for Z homing when homing all axis (G28) The offset in Z, X, Y between the home location and the bed coordinate system is configurable in Marlin with M206: Your answer skips over essential stepts, now that I actually am testing it: 1) how to get the firmware settings currently installed?

How To Use a PC Power Supply With Your Printer! X and Y move at the same time to position the Z-endstop probe to the center of the bed. Most people would expect to read about bootloaders and flashing now, and indeed that is an option. 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 . oh god, I just realized how much I learned in the last 1.5 years about firmware back then I was a noob, now I instruct on how to do this by pointing back to this question! How can I make the following table quickly? I hit the home button and X and Y home in the lower left corner as they should, but homing Z does not move to center of bed. just had to pretty much reverse engineer parts of the ender3 XD.

If Z_SAFE_HOMING was enabled, and the bed properly dimensioned, it could be that the steps/mm are incorrectly defined. Z safe homing does not home to the center of the build plate. I am trying to get the probe to be the center of the bed for Z home. Z_SAFE_HOMING overwrites X/Y min with center of bed, http://forum.repetier.com/discussion/463/g28-and-g29-commands-need-to-issue-m114, BLTouch Smart sets nozzle too high off bed. In your slicer go to the "before" section of G-Code and type in the relevant codes.

Now the printer seems to be of two minds when it comes to finding the origin. To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to (40*60) and HOMING_FEEDRATE_Z from (4*60) to (8*60). If stepper drivers time out, X and Y homing will be required again. Cool that works as advertised. That saves all data in a epr file and you can later use import eepsom settings to rewrite it.

Storing configuration directly in the executable, with no external config files, How to turn off zsh save/restore session in Terminal.app. At this point if I were to try and move the X or Y in a negative distance the software prevents it because it sees the axis at 0,0. For more information, please see our Already on GitHub? What is you bed size and you safe homing settings set to in Marlin config? As I explained in the previous article of Configure Marlin 2.0.3 from scratch, to activate the options you simply have to uncomment them.This is done by removing the two bars in front of each #define, this way the compiler can make use of them and add them to the final firmware. Still not sure why the G28 X Y was homing properly to 0, 0 in the lower left until I home Z, but went and downloaded the latest Marlin Bugfix 2.0.9.3 and it seems to be fixed now. 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. The sensor is working and will set Z height correctly if I don't run G29 for a print, but I need to manually adjust to level the bed still. I've set Z_SafeHoming. Creality offers the firmware on their website as a .hex file - which is hard to edit. How can I detect when a signal becomes noisy? the centre of the bed is not where Marlin thinks it is. 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. How to determine chain length on a Brompton? 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.
