marlin sensorless homing

Both Z motors dock on for a while at the top with a long 'brrrrrrrrrrrrrrrr-brrrrrr', instead of the quick 'br-br' that X and Y now do. If you put the head and bed manually in the initial coordinates, then after G28 the two axes move exactly 1/2 of the maximum coordinates, then the head is parked in Z. What is this about This post will give guidelines on how to flash your own marlin onto a Eryone Thinker S V2 (NOT the V1) or ER20 printer. Mine is between 59 and 60. Dropped motor current. Having a component that according to the conditions of use works differently has no meaning whatsoever. The problem comes when you have to send the signal (S) to your electronic board, if you don’t regulate that voltage (with additional electronics) you can burn the port as it happened to me in my MKS Gen v1.4. Of course, you can configure much more parameters such as limits, polls, travel speeds, etc. Recently a colleague sent me a BLTouch / 3DTouch sensor from the Geeetech brand. 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). As of today, the fixes are in the bugfix-2.0.x branch. The text was updated successfully, but these errors were encountered: Then i tried activate Sensorless homing, my X and Y motor do motion in wrong way. A few prerequisites are needed to use sensorless homing: 1. SENSORLESS_HOMING Marlin can be found here. Successfully merging a pull request may close this issue. Yes, you can connect to the SKR Pro due it have dedicated connector. 3 wire connector goes to servos. 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. Apparently, lowering the homing speed to fairly low values fixes the issue. Sign in I've been doing some tests, and commenting out the IMPROVE_HOMING_RELIABILITY option changes the values completely (the magic number seems to be somewhere 168/169 with the same driver). 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. 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. 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 . I spent the last couple of hours trying multiple things, and it looks like I managed to find a fix for the issue. Either way, I don't think simply closing this is helpful whatsoever. For the rest, I have no idea why is doing that. Ironically, that's not the point of sensorless homing 😂. For the jumpers, each one marked in purple must be jumped: ... [BUG] TMC2209 Sensorless Homing not working hot 3 Nor do I see it practical and much less precise, although at this point I surely disagree with some reader . If you wish, you can find other interesting articles in 3DWork at the following links: I have a MKS SGEN LPC1769 mainboard. Later, the printer will perform 9 probe points automatically at the beginning of each print. 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. Sensitive was set 150. I’ve got mine working but for some reason the five buttons do not work. Upgrading RAMPS 1.4 With TMC2130 Stepper Drivers: Tired of the constant noise your printer is making. 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. 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. Thank you for clarifying that. 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. Thank you ! This feature is so sensitive that it can actually take the place of traditional endstops. Sensitive was set 150. Regards! privacy statement. Disabled Quick home. Now we will save the Configuration.h file and edit a new file called Configuration_adv.h . 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. Trastornados por la impresión 3D, Arduino y Raspberry Pi. Activating sensorless homing is pretty straightforward but, if you want to get stallguard information on the z axis, it requires to plug the Bl-Touch in the Z max pin instead of the Z min. if anything at all the documentaion is behind. with a single search and very easily. Another negative point since if you use glass you will be very fair and in any failure your nozzle will go through the glass with the consequent risk of breakage. I'm going to keep playing with the sensitivity value, homing feedrates and driver current to see if I can get it to work correctly, but so far it's being a pain. Here is a video and the configs files in the description. I'll try to add something to the docs about it. Some Chinese sensors indicate operating ranges from 6-36v, nothing is further from reality. I just have a question, you mention you burnt your MKS board by sending a 12V signal to a 5V pin. I have to say that I tried quite a few inductive and capacitive sensors, I even opted for the original PINDA 2 , which is very comfortable to install since is one of the few that actually powers 5V and gives quite a bit of precision. Please open a new issue for related bugs. That caught me out for a … It’s also a good idea to add these two lines [home bump] right after the sensitivity settings to keep the printer from bumping into the axis ends too often. So you can not leave a fixed value for PLA and another for ABS. Marlin- In the case that connecting the 2 wires to the Probe connector the sensor not works, try to connect to the ZMin connector. X, Y axis move fine (to right and back when adding +10 on the axis). 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. Thanks a lot for your comment! @407s for sensorless homing there is no need to remove the pin. That’s what Marlin is for, to make life easier for us. 2. 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. I checked it twice first it seems that on TMC2209 logic is inverted high values for more sensitivity low values for less sensitivity. I'm about to close it again, but I will update for the benefit of others. You can access it before the printing process and during (yes, you read me correctly) the printing process by pressing the button twice on your display.
