QuoteTinchus2: reset butom works now. IF I press it, i get a "KILLED PRINTER HALTED Please reset" message, and then the buttom does nothing else. Can I change this behaviour, like getting a complete reset? because now the only way to reset the printer is to turn it off?
Unfortunately this can't be changed. However, if you can reach the reset button on the edge of your RAMPS board you can

QuoteModmikeAre sensors affected by power wires in the bed?
Inductive sensors can definitely be affected by the current running through the bed heater traces. Try enabling PROBING_HEATERS_OFF in your configuration.

Increasing the Z offset might help. If your nozzle is too close to the bed, one row of filament might pull on the previous row lifting it up and causing artifacts like you are seeing.

Make sure that none of the tabs on the RAMPS MOSFETs are touching each other. If they do when one MOSFET activates the touching MOSFET will also activate. I had this problem with almost exactly the same symptoms you're experiencing and I've seen at least two other people with the same problem - just bending the MOSFETs to ensure that they do not touch each other should solve this issue.

You can use the same +12V wire for the hot end heater, both fans, and the 6-26V sensor. Saves 3 wires. The other wires should be kept separate.
Good point - I was thinking high-side switching where a common ground would work, but obviously if they're low-side switched the +12V would be the common wire. I'll have to take a look at the RAMPS 1.4 schematics and my external MOSFETs and see

Safety & Best Practices
At current count, I have 15 separate conductors running through my cable chain to the toolhead:
2 for the extruder fan (+12V, ground)
2 for the part cooling fan (+12V PCM, ground)
2 for the heater cartridge (+12V PCM, ground)
2 for the hot end thermistor (?)
4 for the extruder motor (?)
3 for the inductive sensor (+5V, ground, signal)

Safety & Best Practices
I find my inductive probe reliable and accurate, and since I got the 5V NPN version of the probe it was plug-and-play into the Z-min connector. If you're using the 6V-36V or PNP probes you need to worry more about setup and play around with voltage dividers, diodes or optoisolators, but there are easy to use inductive sensors. My only complaints are that you have to make sure that it doesn't prob

The one I use is M18 8mm DC 5V NPN NO LJ18A3-8-Z/BX-5V Inductive Proximity Sensor Switch. It's designed to run off 5V so you don't have to worry about level conversion and has a quite long sensing distance (4-5mm against a 3mm aluminum bed). The disadvantage is that it's relatively large and heavy compared to sensors with closer sensing distances.

QuotenkuckI am running an inductance probe and it it positioned slightly closer to the bed than the nozzle.
Do you mean that the actual physical bottom of the probe is closer to the bed than the tip of the nozzle? Or do you mean that it triggers lower than the nozzle? If it's the former, unless you have a mechanism to extend/retract it I don't see how you could print without the sensor dragging

QuoteRoxyFor an inductive probe, the Z_PROBE_OFFSET_FROM_EXTRUDER number will be positive. It says when the nozzle is at .35mm, the probe will trigger. The nozzle will need to be lowered by .35mm to just touch the bed.
If the nozzle is at .35mm above the bed when the probe triggers, that means that Z_PROBE_OFFSET_FROM_EXTRUDER needs to be -0.35. In general, only probes that use the actual noz

And the prize for biggest idiot goes to... this guy!!! I just spent all day trying to adjust my matrix, and after several hours (!!) figured out that even after writing the documentation for this, I was adjusting my points in the wrong direction!!! No wonder the mesh was getting worse and worse!!!

Got it. If the nozzle is too close to the bed, I should increase the value of the mesh point, and if the nozzle is too far away I should decrease the value. It might make sense to add a comment to that respect to the "Fine-tuning of the matrix" section of the documentation. Something like this, after the "Use the encoder wheel to change the value" sentence:
"If the test pattern shows that the no

What is the exact meaning of the mesh values in UBL? I know they are differences from Z=0 for each point of the bed, but what is the sign? Does a positive value for a mesh point mean that point is closer or further away from the nozzle than 0? I looked at the documentation for UBL and couldn't find any place where it specified how to adjust a mesh point - i.e. if G26 shows that the nozzle is too

You need to use the beta 1.9 version of Arduino to compile 2.0. It won't work with Arduino 1.8.5. The other option is to use PlatformIO instead of Arduino but I don't know how difficult that is to set up.

QuoteLichtiMCThink of foldable probes...
The probe should still trigger before the nozzle hits the bed, right? In which case Z_PROBE_OFFSET_FROM_EXTRUDER would still be negative. Unless I'm misunderstanding what you mean by "foldable probe" - I'm assuming you mean something like a probe that gets moved into place by a servo and then can be stowed out of the way.

The one reason I can see for a positive Z_PROBE_OFFSET_FROM_EXTRUDER is the case where you have a spring-loaded nozzle with a switch where you actually need the nozzle to go "under" the bed to trigger the switch. But in the great majority of cases Z_PROBE_OFFSET_FROM_EXTRUDER will be negative.

Honestly, I think if the setting name were changed to "Z_HEIGHT_AT_Z_PROBE_TRIGGER_POINT" and its sign was changed (so in my case I'd use 1.35 for it) it would make much more sense and be easier to understand.

QuoteRoxyI would recommend you rethink the issue.
And if necessary... discuss with people that have inductive and capacitive probes.
I have an inductive probe. My Z_PROBE_OFFSET_FROM_EXTRUDER is -1.35 and everything works perfectly. The bottom of my probe is about 2.5mm above the tip of my nozzle, but because the trigger distance (around 4mm) is larger than the distance between the probe bo

Per the code it seems like the menu only allows you to set the temperature to HEATER_0_MAXTEMP minus 15 degrees:
MENU_MULTIPLIER_ITEM_EDIT_CALLBACK(int3, MSG_NOZZLE, &thermalManager.target_temperature[0], 0, HEATER_0_MAXTEMP - 15, watch_temp_callback_E0);
So you're on the right track - upping HEATER_0_MAXTEMP will get you what you want, just with a 15 degree offset.

QuoteRoxyIf you have an inductive probe, the Z_PROBE_OFFSET_FROM_EXTRUDER will be positive and not negative.
I can't think of any situation where a positive Z_PROBE_OFFSET_FROM_EXTRUDER makes sense unless you can probe without the nozzle in place (like E3Ds new tool-changing design). The actual physical position of the probe is pretty much irrelevant - only the triggering point matters and if th

QuoteRossosWith 8bit 16Mhz microchip struggling with Delta and CoreXY frames I can only speculate that constant "am I 8bit board or 32bit board?" will only cause an unnecessary stress.
All of the "am I an 8 bit or 32 bit board" stuff is resolved at compile time (the same way different board pinouts and such are currently resolved in 1.1.x) so this should have no effect on performance.
