I got my crtouch 7x7 mesh with 2 samples each down to 60 seconds. Fast movement speed between points, minimum movement for probing. Z height is only 4mm, so the pin hovers around 2mm above the bed during probing and retracts only 2,5mm, so barely lifts above the bed since a crtouch has typically a dead travel of 2mm. Probing speed is 10mm/s, raising speed is 20, horizontal speed is 200

@ChozoSR388 Год назад

Great video! Took my 9x9 probing down to just over 3 minutes. Had to tune the X/Y feedrate down to 75mm/min on my Ender-3 V2 due to the bed violently slamming into the endstop switch lol

@bryanodonoghue8007 2 года назад

This is a really great tutorial. I've gone from slow 5 x 5 x 3 probing to 8 x 8 x 3 probing. I'm doing faster probes now for a greater number of probe points !

@bryanodonoghue8007 Год назад

@akashic seer It appears to work fine for me. What's your definition of not working ?

@akhilsubhash7644 Год назад

@davidolivares2857 Год назад

Hello, and thank you very much! Thanks to you I managed to update the Marlin firmware on my Ender 3, to install the official BLTouch and now to increase the probing speed! You are a great and amazing person with a pedagogy that one rarely finds and that, as a teacher, I really appreciate! Kind regards, David.

@thebob94547 2 года назад

Thanks for your great videos!! Interesting fact: My BLTouch on E3P does not flip in totally for each level point probing. Instead it just "dips" until it reaches a certain point. Was different when using the Creality firmware - there it snapped in. I have increased the speed as well an end up in a 4x4 mesh in nearly 60 s (haven't taken the excat time). Runs in this config since 1 yr without any hickups.

Thanks for this video, it really helped speed things up. The only downside was it messed up my Z-Offset so it was printing in air. I had to setup the Z-Offset again, but now everything is working.

@lorlimann 2 года назад

Great tutorial! This helped me get my BLTouch back and running after I was finally frustrated enough with my inductive probe. However, I believe your methodology is flawed. The variance the printer reports is the overall varianace of the bed. In my experience, this may well change with every heating cycle. I think a better way of testing for probe accuracy is the M48: Probe Repeatablity Test command in Marlin (must be uncommented in configuration.h).

@ALittleSlowest 11 месяцев назад

Neither of those is that standard definition of variance, which is, roughly speaking, a way to determine the average distance each measurement is from the average of the measurements. See en.wikipedia.org/wiki/Variance

@KixMan28 2 года назад

Thank you for this intetesting and comprehesive video. I will test these setting at my next firmware update.

@mananamanana9943 5 месяцев назад

Thanks man. This helped me alot with ultra slow probing.. like a lot a lot.. But one thing i noticed is that your probepin does not retract all the way up in the housing when you probe.. I have followed your guide step by step. but my probe pin retracts all the way when activated.

@basicmods 2 года назад

Great video. When configuring my firmware a while back I set it up with a 5x5 mesh and was able to get it down to about 90 seconds. I'll have to review with the pointers in this video. Related question, how often do you recommend updating firmware? I got a setup that works for me over a year ago and I haven't updated since.

@Crosslink3D 2 года назад

I have upgraded more or less always when a new Marlin release came out . With the firmware factory it’s very much no work.

@zeno6111753 9 месяцев назад

Great! Exactly what I was looking for. Can I make these adjustments from Octoprint or do I have to compile and reflash the firmware?

@coupe16v86 Месяц назад

Yeah, but multiprobing must be enabled. Already the bltouch is not exactly very precise, if we then remove the double touch, we will only worsen the results. With single, we haven't average on that probed point. Btw, imho, It's better spent more time to level, and accuracy, that imprecations for 1st layer issue!

@AndrewAHayes 2 года назад

Is there any chance you might do a video on Meatpacker on Marlin and its corresponding Octoprint plugin? it cliams to double the data rate sent to the printer from the SBC

@Crosslink3D 2 года назад

Yes, that’s on my list of things, thanks for pinging! 😉

That XY Homing Speed made my Ender 3 slam the gantry in both axes... lol. I had to put those back to 20-30mm/s.

@ChozoSR388 Год назад

Had the same issue with my V2 lol Thought the hotend was colliding with the bed til I remembered the XY homing speeds.

@bigdaddy6229 2 месяца назад

I had the same issue but 75mm/s seems to be the best speed on my ender 3

@tectonico3d173 Год назад

Hey great video! I loved it! I am only having one final thing that I would like to improve and probably you know and could give me a tip? I would appreciate it very much. Right after probing is finished, the nozzle goes down in the right end corner where it did finish probing with the bltouch. and then it moves to the printing zone (but just a few millimeters above the bed). and then in the prinitng zone goes down again to completely touch the bed. I would like to change this behavior and move the nozzle to the printing zone but with the nozzle hight around 2 cms or similar (the important thing is that the nozzle is not so close to the bed) and then in the printing spot go completely down to touch the bed. Do you know by any chance how I should look for this information or in my case what would you do? thank you!!

@cellularmitosis2 2 года назад

I thought I understood what the variance meant but later in the video I realized I had it backwards. Can you explain this in more detail?

@VPhu739 Год назад

@marioberlin8690 Год назад

Super, jetzt verstehe ich mehr, mein Großer…👍 Hab dein Abo gespeichert…😊

@Bretware904 2 года назад

This is not the way I setup Bl Touch, there's no reason to probe before every single print. Best when set up to restore after G28 and probe twice with one extra, this will drop the probe that is off by the most. With this set up you simply probe and then save the map to your eeprom, the machine loads the map before the print. For any reason to get out of range you manually launch the probing and save again

I'm using a precompiled Marlin fork for my Ender 3 V2 which allows to change many if these things on the fly in the display. Just by coincidence changed similar things today to 6x6 with only 1 iteration and HS mode.

@MaljakSC 2 года назад

Hi there, today i tried flashing the latest firmware with changes for adding the bltouch and these sped up changes on my ender 3 max. but the printer always crashes and reboots after like 1 minute into gcode, what could have gone wrong?

@svin3819 2 года назад

First off wanted to say thank you for the video. I followed it to a T. Everything works. But I do have a question. I get the fast movements in between probe touch points. But it slows way down at a distance before the probe point and creeps XY only Z is great. Would you happen to know what setting in marlin this might be?

@doron910 2 года назад

It takes me 2:35 min (SAME config & 5X5 grid) for some reason my printer waits 2 sec after each probing point and also after the quick probing travel there's a short travel with *really* slow speed... so weirddd :( maybe because of the latest bugfix firmware I picked up?

@d2ka 2 года назад

Does it work with 3D touch from Trianglelab? Also when I increased the homing speed for XY to about 120*60 the whole unit just smashed the X endstop so fast that it didnt triggered the endstop properly. I would be careful with this setting.

@Crosslink3D 2 года назад

Hey Dariusz, I have one printer with the 3D Touch, I will give it a shot and let everyone know asap! About the homing, yes that's something everyone needs to test. But that's also true for all the settings anyways.
