I am hoping that I can find someone else who has worked out the kinks and figured out the proper extruder settings and BL-Touch offset from nozzle with the Micro Swiss NG Direct Drive extruder. This is the newer direct drive with the motor angled. I am in the process of installing this on my Ender 3. I have an infant son at home, so my time I can dedicate physically to my machine is limited… hoping to get most of the info so that I can get it working as quickly as I can get the parts installed.
Greetings,
I am assuming that you have the basic fan shroud, and basic bltouch mount correct? I would give you my offset, however, I have an aftermarket fan shroud and bltouch mound installed on my printer. Fourtuntally there is a really easy way of figuring out the probe offset, and it only takes a couple of minutes.
First Tape a piece of paper to your bed, and then lower your nozzle with the printer controlls until it presses into the paper and makes a mark. Then Move X until your probe is aligned with your mark, and take a note of the distance it moved. Then do the same for y. Now here is the important part, take you numbers, mine were 55 on X, and 14 on Y, but these numbers are wrong. If your probe is behind your nozzle on y, they you must flip the polarity of the number. What I mean by that is you must turn the positive 14 (in my case) to a -14 because the bltouch is behind the nozzle. On the x, because the nozzle is is to the left of the nozzle, you must also flip the polarty of the number, from 55 (in my case), to -55. This is probally confusing, so ill give another example. If your probe was instead in front of the nozzle on y and to the right of the nozzle on x your initial numbers would be X: -55 and Y: -14, you would again have to flip the polarity of the numbers, from -14 to positive 14 and so forth.
My final numbers are X: -55 and Y: -14, and yours should be in this ball park as well.
Furthermore, I am working on Klipper settings for my NG extruder as well, I will share when I am confident in them.
Happy Printing!

@RonRN18 ,
Did you figure out the settings? I just set up Klipper today on my Ender 3 with a BTT SKR Mini v3 board. I also have a MIcro Swiss NG with a BL Touch (stock mount , stock fan shroud), and I’m looking for what the settings should be.
Hello!
Just got it working. It took a while to tweek, and you will want to check some settings as I am using a Big-Tree-Tech Manta. I am pretty confidant that I have got the pin assignments right, but you should check. But that should be pretty easy since BTT posts their pin assignments in their manual, and they are pretty easy to input.
You will also have to change some BLtouch settings, since I have a Cr-10 V3, and you have an Ender 3, mainly the bed size. You will also have to change your min and max probing area settings, and I have included an amazing video. 13:00 is where min and max probing area calibration starts, but the whole video is amazing, and watch it if you have any troubles. All resources are at the bottom of this massive post!
Happy printing!

Hi Blake,
where is the link to your video?
Kind regards, hcet14
Hello,
Sorry for not responding sooner, I have been sick for the last 5 days, and haven’t thought of this post until now. Klipper discourse group only lets you post two links per post for some reason. Obiously I should have just posted twice, the second one with the other two links. But I didn’t then, so now here they are:

I also have a BTT Manta M8P with Tmc2209 that will run my Voron 2.4 when it gets complete. I’m wondering if you would be willing to share your printer cfg with me so I can see how to setup of my current printer with Microswiss NG, and have a good start on my Voron. My NG is printing ok currently but I only have the rotational distance set and looking at your settings you posted for the extruder, I see your distance is set in the 40s and mine is around 7.85. I don’t have the gear ratio either. When I loaded my cfg with the 46 rotation distance and gear ratio of 3:1, my extruder started skipping and grinding when I tried to run an extrusion calibration. Any advice/help would be great. I understand the cfg file isn’t plug and play but I’m having trouble understanding it all together. So much learning curve and I really just want to print decent tinkers. Thanks
Sure!
I’m absolutely fine with sharing my printer cfg, it’s not like I am the fastest speed printer who wants to keep my settings secret lol.

Thanks so much! Is this with the micro Swiss NG? How do I find what the full steps per rotation is for NG? The instructions from micro Swiss say to put esteps at 400 but I can’t figure out how that transfers to Klipper configuration. I calibrated the rotation distance with my caliper and extrusion at 100mm so that part is dialed but my dimensions are still off for printing. Also holes printed in walls come out flattened. Thanks for sharing.
Hello,
I just noticed that you asked for something that I didn’t respond to. I am so very sorry! Yes, this is for the microswiss ng. Btw, please don’t paste my config into your voron, I have a cr-10 v2, and a voron is much different, just use it for pin assignments and such.
Here is a fantastic spreadsheet that I used to calibrate my printer: Copy of Klipper Calibrations - Google Sheets
Just make a copy of it for your own use, but I have the settings pasted in it that you should need to use. It even has a handy built-in calculator that is used for calibrating your rotation distance to get accurate extrusions! It also takes esteps and converts them to rotation distance.
Holes in my walls come out flattened as well, I think that it might have something to do with the hole size and a setting in the slicer. When I print a benchy, it has nice round holes, but when I try to print small holes, they become flattened. Personally, though, If trying to screw something into it, it makes it very easy for the screw to grip it. I think the slicer just doesn’t pay attention to that type of detail, If you want, just support them. that may also do the trick.
Hope that helps!

Just seeing this. Did you create the document? Pretty intense! I didn’t use your config file, I just wanted to look and see what I might have been missing for the NG extruder settings. I am finally running ABS and had a learning curve with bed sticking and now part cooling. I went with printing my own parts for the Voron because you have to print to get better. A magic slicer profile would be nice though lol
Hello!
No I found the document from a yt video on how to adjust rotation distance.
Blake
the spread sheet is fine and all but which is it? 1,8 or ,9
Could you be more specific?
Are you asking about cells E2 (F2) and E3 (F3)?
