Happy holidays and thanks Chris from Germany. Yes, I‘d like to see a vid about the the remaining setup in Marlin 2.0 final. At the moment I’m struggling with the Bltouch. The printer doesn’t consider the results from the leveling during printing an thus some areas are ok on the bed and some not (the nozzle is too much above the bed). I don‘t find the mistake.

[@ChrisRiley]

Happy holidays!!! Cool, I will work on that. I have heard of a lot of people struggling with this. It seems like some of the newer sensor are inconsistent.

@Klaus I have exactly the same problem. And I thought I was alone with it. I updated my firmware several times and flashed but no improvement.With the old firmware (Marlin 2.0 bugfix from August) never had any problems but since I flashed the new Marlin I have had the problem. Maybe Chris Riley knows a little more about it?

12v sensors may be a better choice as detection distance will be higher. Easy to connect with mosfet. And other sources are saying that bltouch it's much better than inductive sensors. Prusa is using integrated temperature sensor (while wire) to compensate temperature deviation but it's still sensible to be humidity levels as well and bed material.

[@ChrisRiley]

12v does give you a bit more distance. From my testing, inductive probes are more accurate than bltouch sensors. Are you thinking of capacitive sensors maybe?

I wish Marlin would warn you about high deviation like klipper does. you can set a value in klipper (I use 0.05) and if the deviation between 2 or more probes get higher it tries to probe again (I set it to try up to 2 times) and if that doesn't work it'll just stop and throw an error!

11:17 I tried changing mine to Grid_max_points_x 5 which gives me the 5x5 probed grid when I manually tell the printer to auto level. but now when it prints, once it gets to the g29 command my printer goes to the corner like it's going to probe but instead just pauses then continues on with the print. I have it enabled in the firmware to reload the mesh after G28 and it gave me a great first layer so I believe it did in fact load the mesh. The G29 it right after the G28 am i missing something in the start G-Code?

[@ChrisRiley]

Most of the time when you see that in Marlin the probe has throw an error. If you can't figure it out, you can turn on debugging and it will throw the information in a terminal window for you. * Enable detailed logging of G28, G29, M48, etc. * Turn on with the command 'M111 S32'. * NOTE: Requires a lot of PROGMEM! */ //#define DEBUG_LEVELING_FEATURE

@@ChrisRiley Thanks for the help Chris! I managed to fix the problem by just changing #define Z_PROBE_LOW_POINT from -2 > -7 worst case if the probe fails my bed will ram into the nozzle for a few seconds. -2 wasn't enough for my -3.825 z offset. But of course, fix one problem and another arises. When the print starts the Z moves to 6mm and prints in mid air. changing the Z offset does nothing, setting it to 10 or -10 offset doesn't matter it still goes to 6mm for the print :/

[@Enjoymentboy]

This is hugely helpful. I have progressed in my 3D printing to the point where I now need to modify firmware settings and this was exactly some of the information I needed to understand. Thank you. I'm in the process of replacing the board and screen in my anycubic kobra 2. The firmware is so sub-par it is really sad. That trigorilla board has got to go. I'd mess with firmware if I could find a build for it but since I can't it's going to go. But I want to reuse as many parts as possible and the inductive probe works well so I didn't want to replace it. This video gave me exactly what I needed to keep it.

[@ChrisRiley]

[@jrperki1]

I have some experience with g code on vinyl cutters, CNC routers, and laser cutters but my BIQU BX is only my second 3D printer. I am confused about two things that I think you can probably answer off the top of your head. 1) With Bilinear bed leveling, are the adjustments relative to the front left of the machine or the middle. It would seem I should set Z0 at the first point or maybe the highest point to make sure the bed leveling is always relative to the real Z0. 2) I never understood why we set Z0 to 0.1mm (thickness of paper) instead of actual 0 when my first g code move sets Z up by the thickness of the first layer. Shouldn't I move Z down to the thickness of paper then move it to a safe space and set it down an additional 0.1mm before saving Z0?

[@ChrisRiley]

They are relative to the front left on that machine. The thickness of the paper should represent zero. It's just to give you a feel for where zero is.

[@qwewer6]

Thank you.

[@scharkalvin]

Is it possible in Marlin to wire a standard Z endstop switch to the Z-MIN-ENDSTOP port and an inductive probe to the Z-MAX-ENDSTOP port, and then have the firmware use the endstop switch to home the Z axis, but use the inductive probe to level the bed? In this case the endstop switch fires when the nozzle just touches the bed, and the inductive probe will fire at some point above the level of the probe (which is the Z probe offset value). I'd like to add the inductive probe, but keep the z endstop.

[@ChrisRiley]

Yes, you can do this, you would use this feature #define Z_MIN_PROBE_PIN 32 instead of this one #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN then just use your max endstop pin from your pins file.

[@KPTnVAN]

In my case Z_MIN_PROBE_USES_Z_MAX_ENDSTOP_PIN works also fine.

[@dahorsefarm287]

I'm having a lot of problems. Will a NPN NO (normally open) probe logic work? Does the normal Z end stop switch make the circuit OR break the circuit? My probe under a 5 volt power supply connection always has 5 volts on the signal wire. Touching the probe end with many different metal objects does not change the 5 volts on the signal wire. I think my 'NEW' probe is bad.

[@ChrisRiley]

Sounds like the probe might be bad, you should see if go low or high as you trigger it.

Wow! This is just the tip of the many variables as variety of printers there are. I am tweaking a FLSUN i3 Plus and Marlin misses the FLUN printers! Oh well.

[@ChrisRiley]

The options for different 3d printers seems unlimited these days.

[@MichaelGamber]

I think maybe you are confusing Normally Closed vs Normally Open (NC vs NO) for PNP and NPN. Maybe I need to watch again closer, but when you invert the login in Marlin you are more accurately changing from a NC vs NO. PNP is Sourcing, which means the switch will push the voltage out the signal, thereby pulling the signal high, otherwise it is left floating. The NPN is sinking, which pulls the signal low (0v ref) when the signal actuates. Both of these type switches can come in NC or NO configurations.

[@ChrisRiley]

I very well could be working off assumptions from experience. I will have to do some experiments.

Hi Chris! Thank you for the vid, it is really clear! However I have an issue with my Anet, where I just installed the BLTouch and the latest marlin firmware. I set the probe up, as in your video, but when I start printing (after G28 and G29 and after ZO setup) I don't know why but the nozzle of my e3d dives into the bed. It makes a side of the object quite nice, while when it moves to the right side of the object, the Z moves down and the nozzle is almost carving my bed. I can see the lines the nozzle makes on the bed. It is super weird, because it starts fine, with the right first layer height but then the Z goes down. It seems that the machine is trying to leveling the bed, but in the wrong direction. It should lift the Z on the right side of the bed, because it is a bit higher than the left side. I tried to set the babystepping movement to true, but nothing changed. Do you have any clue on how to solve this problem? Many thanks again for the guide and the help!

[@ChrisRiley]

Hi, I'm using a 5v inductive sensor and ubl together with a skr e3 mini v2.0 board. I needed to extend the cables of the sensor so I first used dupont connectors for that. Everything worked fine. Now the only change I made is to get rid of the dupont connectors, solder on the wires and finally put all my "x carriage" cables into a mesh sleeve...it was a pita and involed a lot of pulling on the cables. After all that now if I do g29 p1 the sensor probes all reachable points, beeps but then moves a bit to the side and the nozzle just crashes into the bed....no idea why. I can't imagine I damaged a solder point or sth... and I also was careful to wire it corretly. I grab the 5v from the probe header on the board, gnd and signal from the z-endstop header. Any ideas what could be wrong? I really don't want to pull the probe cable out again of the mesh sleeving :(

Only thing I can think of is you aren't getting readings to the endstop/probe pin. So it fails probing and has no idea what to do with your offset. Check the wires again I guess.

BLtouch setup questions. 1. BL offset setup? 2. TMC2208 endstop sensing? 3. So my BL is now my z endstop? 4. Is a BL considered a PNP or NPN; guessing the code automatically sets it up when selecting BL? How do I setup a BLtouch when the sensor is not adjustable up or down? When it's deployed I'm guessing it's going to hit z endstop before the extruder hits. Then I'll retract it to drop the extruder with baby steps to calibrate z offset. I'm trying to set up with my TMC2208. Does z safe homing relate to the 2208 endstop sensing. I'm close, but need some confidence on not crashing head.

[@ChrisRiley]

1. BL offset setup? That's the measurement from the nozzle to the sensor. 2. TMC2208 endstop sensing? No, but 2209's have it. 3. So my BL is now my z endstop? It can be, or you can do both. Most times yes. 4. Is a BL considered a PNP or NPN; guessing the code automatically sets it up when selecting BL? How do I setup a BLtouch when the sensor is not adjustable up or down? When it's deployed I'm guessing it's going to hit z endstop before the extruder hits. Then I'll retract it to drop the extruder with baby steps to calibrate z offset. I'm trying to set up with my TMC2208. Does z safe homing relate to the 2208 endstop sensing. I'm close, but need some confidence on not crashing head. I am not sure, but I would call it an NPN, it will alert you if it is not set correctly. To setup the height there is some guess work involved, the bltouch doc trys to give you a guide for where to place it. The sensor should tap the bed before it hits the endstop. Correct, it will be up when babystepping. No z safe safe homing just lets you home in another location besides the corner of the bed.

Thanks for getting back to me Chris. MKS has Marlin 2.0 as one of two firmwares, however, they don't support it well and it seems that the original Marlin 2.0 was to be compiled with Atom and an earlier version of PlatformIO and with updates and the fluid nature of Marlin the compatibility was lost, or may never had been there for the TFT v1.1. It seems the people that have been able to get it to work have TFT v2.0. There are a couple guys within the Marlin world that may be trying to get the version 1.1 TFT put into the main Marlin again. The fork version they are working with did get Marlin working on my board and screen, but touch buttons are not working yet.
