Why not install a leveling sensor to level at a single central point in the bed (SAFE_HOMING), and let Marlin generate the mesh of points and worry about the rest? The problem is that around the "magic numbers" stallguard triggers as soon as the homing starts (without anything connected to the stepper, again) and then occasionally it will never trigger. Marlin 2.0 on the SKR 1.3 with TMC2209 and sensorless homing @407s for sensorless homing there is no need to remove the pin. Irritating. Then i activated function, mechanical switches was unpluged from board and installed special jumper in XST and YST slots. Dropped motor current. by BTT DIAG pin was removed how told in manual. I leave you an example of my startup script on each print: To finish, and having activated BabyStepping you will have your own menu called Offset. I'm starting to consider it may be a hardware issue with the drivers themselves, but I have no idea how to test that either. I will go into as much detail as possible but please keep in mind that marlin is constantly being developed and changes can lead to a setting being named differently, a file being renamed and so on. You must measure these values ​​to enter on your printer (do not use mine). As soon as I change the sensitivity to anything bellow that (M914 X104) it just tries to home forever until I kill the machine. If using stealthChop it's important to have a well tuned chopper frequency as well. For bltouch you not must be worried of this, just connecting to the sockets that appear in the article will feed at his correct voltage without any issue. SKR v1.3, and BTT 2209s. If I set the sensitivity to anything above 105 (M914 X105) and try to home the axis, it moves for about 1mm and then immediately stops. I had a commercial at the beginning (a completely disaster), so I decided to design and manufacture my own to my liking and needs. I am only going to detail the steps necessary to make the TMC2209 work without sensorless homing, i won’t do a full tutorial on each option that might be required to make your specific machine work. to your account. Or alternatively, you can follow us on our social networks. In this article we will only discuss the options to modify to support BLTouch / 3DTouch. No sensativity setting seems to change Triggered State in M119. Direction in conf - ok. Upgrading your RAMPS 1.4 (or most any AT Mega based controllers) with the TMC2130 stepper motors might do the trick.In this instructable I will not go into the technical babble of PSI, Master/Slave… Of course, this distance is at your absolute choice, it is only a guideline value. I think I might have figured out why people are having issues with this. I usually use optical infrared sensors for my printers, but I wanted to try the BLTouch sensors since none had fallen yet by my hands. thx, In G28.cpp I raised the acceleration rate from 100 to 500 for homing which after lots of testing allowed me to run a higher sensitivity without the steppers tripping the endstops right away when starting to move. With the Eryone 2209 you can have sensorless homing without the need to bend or modify the pins. That caught me out for a … Marlin.zip. If you have issues with some versions of Marlin (sometimes happen), use the ZMin connector. with a single search and very easily. Just one important thing. So basically, it works when it's already homed. by BTT DIAG pin was removed how told in manual. TFT 35 V3. The drivers come with Jumper cables, If you use a cable from the top pin for the Diag and connect it to the Signal pin for the end stop it works. When you turn on the printer you will see that the sensor does a little checking (unfolds and retracts the probe). I have a suspicious playing with values such as off time, blank time or hysteresis values might be the answer to solve this. You will need to add the self-leveling function at the beginning of each print. I'm using TMC 2209s on an SKR Pro. It feels like what is happening is that with the higher sensitivity number, it stallguard triggers with literally nothing connected to the stepper driver as soon as it starts, and the lower sensitivity numbers never trigger. But when I home the axis, they move to the right/front insted of left/back. We’ll occasionally send you account related emails. In the end, so that everything is square, you end up making several passes, especially if you are a precision maniac. I'm assuming this is the stallguard triggering, since I haven't been able to get a read with M119. Moreover you simply need to place a jumper connector on the DIAG pin for the axis that you wish to use. I updated my start gcode to drop it to 200, home, and then bring it back to normal mA (800 in my case). Have a question about this project? Then i tried activate Sensorless homing, my X and Y motor do motion in wrong way. if anything at all the documentaion is behind. I downloaded the latest Marlin bugfix version which is 2.0.6 at the moment of writing this article. State never triggers in M119 command. This procedure is not optional. @uorbe001 I have sensorless homing and probing working (after few weeks of testing) with BTT TMC 2209 v1.2 on a SKR Pro. Furthermore, the connection of the BLTouch / 3DTouch sensors to the boards is relatively simple and you do not need to carry out any electronic modification as it happens in other sensors. It failed 20 tests on 800ma and failed 0 on 200ma. SPI / UART interface of the TMCxxxx wired to MCU (stand-alone mode does not work) 3. I've tried to switch motor and driver with no luck. latest build of marlin 2.0. all libraries up to date. So I got down to work for Configure BLTouch with BabyStepping in the last Marlin available today and satiate my curiosity.. Onboard Sensorless homing function, which can be used by plugging in the jump cap 4. You can buy this type of sensor in any online store, since they are very common in the world of 3D printing. I just got (and tried) a couple of watterott TMC2209's, and I'm getting the exact same result as I was with the BTT drivers. I've got the exact same setup, except I don't use the stallguard feature of the 2130's yet. Now we uncomment the option Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN. Everything working as intended. Hey, im having exactly the same issue except my endstops are now reading "open" on X/Y but the motor just stutters as if its sensitivity to sensorless homing is very low? In G28.cpp I raised the acceleration rate from 100 to 500 for homing which after lots of testing allowed me to run a higher sensitivity without the steppers tripping the endstops right away when starting to move. Trastornados por la impresión 3D, Arduino y Raspberry Pi. TMC2209 with sensorless homing on XY. 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. My leveling BLTouch is 37mm to the right of the nozzle, and 2mm behind it, so I would put the following settings. If you wish, you can find other interesting articles in 3DWork at the following links: I have a MKS SGEN LPC1769 mainboard. I tried with M119 but it's always open (as expected, I guess) and M122 is not helping. I also created a custom homing button in OctoPrint. on the skr pro manual it states that you cut it if you want to use endstop switches, you keep it if you using sensorless homing/probing. 100% success rate since I've done that! Both the TMC 2208 and TMC 2209 both have 1/256 interpolated and native 1/256 stepping support. Now we must uncomment the AUTO_BED_LEVELING_BILINEAR function and then the RESTORE_LEVELING_AFTER_G28 function, so that they remain active in our firmware. The main reason for me would be not having to be leveling 4 corners with a sheet of paper or making squares in bed. Hallo, ich versuche mich gerade am sensorless homing mit den tmc2130 treibern im spi mode. It doesn’t give me any sense of precision, since what I’m looking for is an immutable (or at least minimal) measurement. Once the type of self-leveling that we want Marlin to carry out is configured, we will indicate with the GRID_MAX_POINTS parameters the number of probes (or tests) to be carried out. Successfully merging a pull request may close this issue. It's problem only if i activated Sensorless homing. Previously I would have to go down to 70 before I changed the homing acceleration values, I have it at 60 and 94 for z-probing, I will test with those G28.cpp changes as soon as I can. The 2 wire is the same as your example, but the spot that you show on the boards don’t exist on mine. It is not a major problem, you can change within the Marlin firmware and indicate that for Z- we are going to use the Z+, but you have to make unnecessary modifications. Already on GitHub? Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. A few prerequisites are needed to use sensorless homing: 1. This connection is similar, but you must make sure that you have the jumper activated, so we will make sure that the level sensor reaches the 5v. In this way, and in real time, you can adjust the offset while you are making the first printing perimeters, and leave a perfect fit. Hi all, after getting a couple of issues resolved on the Marlin Github, there is now a Marlin build that supports an SKR 1.3 with dual y and z endstops in TMC2209 uart mode with sensorless homing. It would not be surprising if he had left me something in the pipeline, if so, do not hesitate to notify me in the comments at the end of the article Install and configure BLTouch / 3DTouch in Marlin 2.0.x (MKS Gen, SKR, Anet A8, RAMPS). necessary (very important). Ezabl Pro using SKR 1.4 Turbo Probe port (P0_10) Installing and tuning the Ezabl per instructions, M119 shows open when clear of the bed and triggered when nozzle 2mm above bed. Recently a colleague sent me a BLTouch / 3DTouch sensor from the Geeetech brand. If you have read the complete article, I congratulate you. Some Chinese sensors indicate operating ranges from 6-36v, nothing is further from reality. This is done very easily by configuring yourself in your favorite Slicer (Repetier, Simplify3D, Cura, etc.). Below I leave you two affiliate links to Amazon and Banggood. This feature is so sensitive that it can actually take the place of traditional endstops. Same setup here SKR 1.3, and BTT TMC2209 v1.2, was having the same problem using source from BTT repositories, my situation was trying to home to XMax and YMax, found 2 possible solution However now i have an issue with it homing, changing direction and running to the other side(both X and Y) and running till it skips belts, Then changing direction again and homing successfully. I usually make 9 checkpoints before each print, you can expand or reduce it, that is up to you. Also I found that 2209 have not the same sensitivity and my guess depends on the quality of the silicon. Specs: SKR1.3, TMC2130 Sensorless Homing, Marlin 2.0.5.3, Ender 3. But for starters it is more than enough. I don't think closing this issue with a comment saying this is a setup issue is helpful to anyone. I don’t want to calibrate that distance again if I change the filament from PLA to ABS, it’s a hassle. Before starting I have to confess that I do not have a commercial 3D printer as many of you may have ( Anet A8 , Ender3 or Artillery X1 for example). @uorbe001 I have sensorless homing and probing working (after few weeks of testing) with BTT TMC 2209 v1.2 on a SKR Pro. You signed in with another tab or window. I have just configured a TMC2209 for my X axis, with UART. What would i change if I wasnt using the mechanical z endstop? There's either some obscure parameter/combination of options to make this work (in which case having it on an issue would be helpful to others) or an actual bug in the implementation. Optimize the plate and frame to avoid the phenomenon of screw hole gap and screws hitting components 5. I spent the last couple of hours trying multiple things, and it looks like I managed to find a fix for the issue. E-Mail: info@3dwork.io So basically, @boelle was correct in saying this was a setup issue, but to my knowledge, the homing speed affecting the sensorless homing isn't documented anywhere. My assumption was the lower acceleration was causing a false stallguard detect when the axis first starts to move and the faster speed allows it to overcome the initial load it sees when it is starting from a stationary position. In this way we can continue writing 3D printing guides and articles on interest. Yes, i know. My assumption was the lower acceleration was causing a false stallgaurd detect when the axis first starts to move and the faster speed allows it to overcome the initial load it sees when it is starting from a stationary position. Naturally you'll need to have your min endstops wired up or you'll have a machine crash when it tries looking for said min endstop. However, you should not worry because when configuring the BLTouch sensor the options to be modified in the Marlin firmware will be exactly the same . If Marlin detects an error where the driver has shut down to protect itself, it can stop the print to save both time and material. I have always used leveling sensors on my machines, as leveling the four corners of the printing surface with a folio is definitely not my thing. BLTouch / 3DTouch sensors are mechanical, so they are not affected by heat, humidity or the type of material on your printing surface. The sensitivity is affected by many things and so needs to be determined by trial and error, but I don't think the datasheet says anything about those three affecting the readout. I have tried setting up floats for the value but it won't accept them, and I also tried switching it with another TMC2209 with exactly the same result. As I have seen in some places, but it was a little short after some tests and I decided to set it to 2.5mm. Upgrading RAMPS 1.4 With TMC2130 Stepper Drivers: Tired of the constant noise your printer is making. Wrong way only for G28 command. Either way, I don't think simply closing this is helpful whatsoever. Just adding in i have this exact issue. I don't know if this is stallguard actually triggering, or it's a different thing, is there a way to tell when it's triggered? Well, let’s start configuring our Marlin firmware to support BLTouch / 3DTouch sensors. MarlinFirmware/Marlin. As of today, the fixes are in the bugfix-2.0.x branch. You are right the sensitivity value is a pain to find. I usually use optical infrared sensors for my printers, but I wanted to try the BLTouch sensors since none had fallen yet by my hands.
