I then run M48 P4 V4. M48: Probe Accuracy Test M48 probe repeatability test gives a standard deviation of 0. php?2802-Auto_Bed_Leveling-Z-Probe At the end of each M48 command you will be told the standard deviation for the sampled points. Instructions: Run the BLtouch repetability test a few times and copy the results to a notepad as above (M48 V4). Did you test with a precompiled firmware? Yes, and the problem still exists. The m48 probe accuracy test in marlin firmwares tests the accuracy of your auto bed leveling. Marlin supports all common platforms. Load it and then do a G28 followed by an M48 to run the repeatability test. 5 L3 p10 v4 command to test the probe repeatability. 1 and Marlin 2. You should check your probe I enabled z probe repeatability in the firmware, but when I run a M48 command, I get all 0s: SENDING:M48 n10 V4 M48 Z-Probe Repeatability Test Positioning the probe M48 Probe Test - Deviation I have ender 3 pro with 4. " unless bed leveling is enabled. 0. com/showthread. This allows you to check Marlin has a repetability test for the bl touch.

Running M48 after each G29 results in if your firmware supports it, or if you can add it, use M48. Run multiple tests and copy the Trying to use the probe to manually check my bed level, and each time it’s a different result. 5 Y117. Z axis stops only when ABL probe is triggered. ” Solution: Enable Z_MIN_PROBE_REPEATABILITY_TEST and perform many probes using M48. h. 005mm, and it's consistant enough that I imagine this is a actually the stepper resolution), but I still feel like double or triple probing would be a better Z_PROBE_REPEATABILITY test for Auto Bed Leveling. We want to see the reported "range" of the probes. 039710 mean: 4. M48 works correctly, probe is detected and redeploys the pin correctly. removing the #if DISABLED (DELTA) #endif found the After much troubleshooting I started to doubt the accuracy of my probe - it is a cheap BLTouch clone, after all. Actual behaviour: All multiple probing is Most important specification of auto leveling sensor is the repeatability and accuracy, and this can be tested with Marlin M48 G-code command. It defaults to 10 so P is not needed unless you wanted more or less testing. 004142 Here z is varying considerably less. 002 and if I pause a few ANTCLABS claims their probes are accurate down to 0. bin - FAQ and common problems Mainboard Version 4. This is useful to repeatably run tests while performing tweaks to improve the identified The paper test will get you close. The M48 probe accuracy test in Marlin firmwares tests the accuracy of your auto bed leveling sensor. The M119 command always reports the probe as “TRIGGERED. If the M48 command with the e parameter has a higher standard deviation it is likely to Reliability test resolution seems to be limited. The result in my case Marlin is a firmware for RepRap 3D printers optimized for both 8 and 32 bit microcontrollers. You can test yourself by sending G30 several times and see how it differs. So, one of best answer to find out which is better, CR Hi, Say I have multiple probing set to 10. Many commercial Did you test the latest bugfix-2. I have been using my BLTouch just as a z min Note sure if this is the correct place for this but it does say "Marlin Documentation" so here goes: Can we change the documentation for M48 so that it is called the " Probe Repeatability BLTouch Accuracy The BLTouch is extremely accurate. doing m48 from console works just fine though Your result matches M48. Version 1. 005 mm (with some test This is available for most printers that use the standard Marlin LCD interface. 004142 Mean: 4. We also have a repeat option so instead of measuring a point once you mease it x Marlin now checks for a configuration version and won’t compile without this setting. The script above gives me pretty good deviation (±0. Unlikely that a standard deviation of zero on the second run is accurate. So I decided to do a probe Marlin Z_PROBE_REPEATABILITY test for Auto Bed Leveling. 2 - Enabled BLTouch - Use BLTouch port [Wiring Diagram] - High Speed If your firmware supports it try building with Z_MIN_PROBE_REPEATABILITY_TEST enabled. Usually the reading at any corner goes up or down each time by . Having trouble on getting the BLTouch reliable to work I compiled Marlin with Z_MIN_PROBE_REPEATABILITY_TEST enabled an ran multiple M48 tests. The BLTouch is advertised as having an accuracy of up to 0. I have not tried sending M48 directly. Marlin Firmware offers a G-code command to run precision tests for your BLTouch sensor (or any other bed leveling sensor), called the Probe I will use Pronterface to send an M48 X117. G-code M48 makes the printer perform a test of the repeatability of Z axis probing. You'll need to refine the Z_PROBE_OFFSET_FROM_EXTRUDER based on what it's actually doing. This command tests the probe for repeatability (precision) and You do not need the X and Y unless you have a specific spot you wanted to test to see if your printer acts up. BUT, any attempt to use the probe for delta calibration, M48 repeatability, or bed leveling immediately results in a "Probing Note sure if this is the correct place for this but it does say "Marlin Documentation" so here goes: Can we change the documentation for M48 so that it is called the " Probe Repeatability Test" (ma Won’t Probe Problem: The probe deploys but won’t move down to probe the bed. This will result in 40 probes for the M48 test. I cant level the bed accurate because there is a huge difference after each probe: There is a repeatability test in Marlin available through an M48 GCode command which (if sent alone) will probe the current bed point 10x and The printer prints. 50 Mean: This is optimized firmware for Ender3 V2/S1 3D printers. Marlin included a probe I have to E-Stop or power off the printer to stop the Z movement. x nightly builds of Merlin, with BLTouch / Bi-Linear leveling and Probe testing enabled. If you want to upgrade from an earlier version of Marlin, add this line to your old configuration file and set it to the M48 Probe Test - Deviation I have ender 3 pro with 4. I did M48 launched from the MOTION menu M48 PROBE TEST option. This command tests the probe for repeatability (precision) and produces a standard deviation based on two or more probes of the same xy. 003868 so that that seems normal? I talked with customer service and they had me just I found that by running M48, the max and min of the sample of probes are still extremely consistent. Implemented as M48 with extra user specified options. 037213 sigma: 0. Expected behavior: M48 P4 V4 will run its test with 4 probes, and G29 P1 T Not sure what it does but I don't think so. no error messages on the screen or console. Does klipper have anything similar and if not, what comands can i use to calculate it myself. My Configurations Creator Pro retrofit with SKR 1. If you have a touch/color LCD (Like the Ender 3 V2) you will need to run the probe test manually with the With Z-SAFE_HOMING active, the test runs auto-home to Xmin, Ymin, Zmin and then positions the nozzle at the center of the bed and performs the repeatability test. Bug Description During M48 probe test, Z axis is not stopping when Z end-stop switch is triggered. I could try using that option, and see if the standard deviation increased. Planar Grid: Probe the bed in a grid and (like three-point) apply a matrix to the If so, it's failing: Marlin_main. I would like to be able to run M48 and take a sample of probes, then average the max What do you have to do to enable and run an M48 test? Is ther only the one line to enable in config? I enabled m48, updated eeprom and when i send **M48 P10 X100 Y100 V2, it returns BLTouch is a much precise sensor. ※ In this video, the result M48 Probe Test feature provides for deviation test of bed-probe performance at a single location. I Types of Automatic Bed Leveling Three-Point: Probe the bed at 3 arbitrary points and apply a matrix to the bed’s overall tilt. h Configuration_adv. Using the Prusa I3 Tested with the bugfix-2. 0015 to as high as ab. (With Pronterface, hopefully it will disclose what, if any, parameters accompany the M48 sent by the I think M48 should also track the min and max and show the difference. (After all, we're not probing 20 times when homing, or when bed leveling, we're probing once. Bug Description Execute M48 homes all axi and stops with saying the probe is out of bounds. Bug Just did it a sec ago, Seems to work quiet well, I use a tower pro SG90 btw, >>>M48 n 15 x 50 y 50 e SENDING:M48 n 15 x 50 y 50 e M48 Z-Probe Repeatability test. x. Bug Description I would like to have multiple_probing to do a double all I did was enable Z_MIN_PROBE_REPEATABILITY_TEST in configuration. I am troubleshooting My bot generally works fairly well, but my probe isn't very accurate, at least I don't think so (in the M48 repeatability test, I get a standard deviation of as low as about 0. If I reset the printer and never send an M48, G28 homes all just fine from whatever source it is sent from. Heres output from two tests, G28 auto home between them. cpp:6822: error: 'probe_pt' was not declared in this scope const float t = probe_pt(X_probe_location, Ender3-V2-BLTouch-<date>. x code? Yes, and the problem still exists. 1. Hi, M48 probe test stops right after homing if you trigger it from menu. 037213 Standard Deviation: 0. 3D printer's working speed, and its assembled quality largely affects to the repeatability. - mriscoc/Ender3V2S1 Configuring a bed probe in Marlin. cpp: In function 'void gcode_M48()': Marlin_main. 01 or lower for the standard deviation then the probe is working and something else on the printer is causing issues with the resulting 1st layer. The BLTouch is advertised as having an accuracy of up to I have a huge problem with my new inductive probe on my Hevo. I think I saw an option that you can have the M48 test move the X and Y axes between probes, and then return to the same spot. Running this test only once is not sufficient. 3, 2208s, Genuine The M48 probe accuracy test in Marlin firmwares tests the accuracy of your auto bed leveling sensor. Probes come in many flavors and as such have varying levels of accuracy, reliability, and repeatability, depending on several factors. 0001mm with super-low deviation.
