- I made this video since a few of my viewers requested to see the Hermit Crab installed on my BIQU B1.
I'm enjoying how clean and solid it is and it gives my printer a more industrial look.
What do you think? would this be something you would install?

The linear rail type used is MGN12H
Fan duct and BLTouch mount I'm using: www.thingiverse.com/thing:490...
Printer Setup:
* BIQU B1
* BIQU Hermit Crab on a linear rail
* BIQU H2
* Ultistik PEI buildplate
* Dual Z axis
* BIQU (Bigtree tech) SKR 2 controller board with TMC2209 drivers
* Marlin 2.0.9.x - วิทยาศาสตร์และเทคโนโลยี
Nice job. Glad to see a new channel and content regarding 3d printing. Never lose your enthusiasm/passion .👍🏻
Thanks 😊 hopefully I can manage to keep things engaging.
I recently installed this on my Ender 3. Your video was very helpful :)
Just looking at these today. Purchased 2 x BIQU H2 extruders today, one for my Chiron. Looks like a useful modification.
I absolutely love it! It's a very solid mount.
nice review and cable cover
Thank you 😊
Nice to see anything about the Hermit Crab already on youtube. I wonder what fan mount + bl touch mount you use. Any link to that. PS i'm waiting on my Biqu Hermit Crab's to mount my H2's on my Cr10 and CR10 Max. looking forward on more contect from you.
I'm using this one www.thingiverse.com/thing:4901193
Great content, hope you get more subs soon!
Thanks. I'm glad you like it. Hopefully I can manage to up the quality.
palm wheels ware out faster and dust gets around your prints and bed, so there is some advantage to getting linear rails then just better print quality
If your pom wheels are wearing out fast and generating dust then they are overtightened. All of my machines currently have pom wheels and not a single one has wear nor dust.
I've been waiting for this review for a while now. Can you give some details about your total carriage weight now? How easy was it to get a part cooling fan designed for it?
This is the part cooling setup I use. www.thingiverse.com/thing:4901193
As for the weight I can't really say. But it's not a lot more because I removed the NEMA 17 extruder motor, and the H2 has a nema14 and is overall lighter. I also run dual Z axis so i don't think about that so much.
What size were the light blue insulated ferrules you used? A well done, clean installation.
The light blue are 0.34mm². 22awg if I remember the conversation correctly. But I think it would have been better with 0.25mm² I believe that's the size of the fan wires. The 0.34 are holding well so far though.
Already did a pasteprinter or a laser onto this ?
hello here I am attaching some photos on the connection of the harnesses on the motherboard of the biqu b1 could you tell me if it is good and I have one cable left, what is it for, for the x stop you use the original wire thank you for the answer you can give me
Sorry, but there are no photos. But if you can go to the Facebook biqu B1 group and post there. There are several of us that will gladly try and help get you up and running.
Hey man, I got the Hermit Crab the other day and installed my H2 on it, as well as the fan/bltouch mounting solution you linked. I'm having an issue though and was wondering if you may be able to help me.
I've entered the provided probe offset from the Thingiverse page, but I don't think it's correct, at least not with the hermit crab being installed. Whenever I try to initiate G29, my bl touch wants to start in the front right corner instead of the front left, and it tries to probe off the bed. Have never had this issue when using a bl touch on any printer before. Did you get a different X/Y offset for your setup? Any help would be appreciated!
You have to change your home offset values too because the hermit crab moved the hotend forward several millimeters. I'm not sure why it want to probe to the other side though. I haven't had that issue.
@@StackingLayers Thanks for the quick response. I've never had to change my home offset values before, but I assume I can modify them in the config files while editing the firmware right? How did you measure your difference in comparison to stock?
@@760creations you can set them from the screen. Home the printer, then move it to the home corner (where 0,0 should be) then in advance settings on the Marlin screen select the home offset in advance settings
Nice work
Thank you.
Perfect, thank you👍
Glad you enjoyed it 🙂
I picked up the same Hermit Crab/ H2 setup on my Ender 3v2 and I’m trying to adjust my XY offset. Do you have any guidance? I’m just a little lost! Thanks for the review!
You need to adjust the home offsets. One way is to first home the machine then use the screen to move the hotend so that the nozzle tip is at the corner spot where X0, Y0 should be (front left corner) take note of how many mm you have moved X and Y to get there. For example if X shows 5 and Y shows 8 then that's the offsets. If you have a home offset setting on the screen then enter the offsets there. Otherwise you need to connect to terminal connection like with pronterface on a PC and use the M206 command to set them. For example M206 X5 Y8, followed by M500 to save. After that home again and tell the printer to go to X0 Y0 to see if it's in the correct spot repeat to adjust if needed.
Please could you tell me if the backing plate that attaches to the linear rail carriage is plastic or aluminium?
It's all aluminum. There's no plastic except for the electrical connectors.
@@StackingLayers okay - thanks!
Do you have to lower acceleration to account for the extra weight?
Nothing more than what I did after adding the H2 direct drive. I think I have it around 800mm/s
Hey great video and commentary. Did you consider the other tool change systems that are currently out before deciding on the Hermit Crab? The Xchange by printermods, or the Mutant V2 by Whambam are also quite popular. Cheers
I did look at those. They look good too. They all accomplish the same thing in general. I just like the design of the Hermit Crab. I just got a Canbus version which is a lot more advanced. I'll do a video soon.
@@StackingLayers Yea the Canbus version caught my eye too. Having a single USB C cable to the extruder would be quite neat for cable management. I also saw they have an accelerometer on the board, would open up some opportunities for input shaping etc I imagine.
@@StackingLayers Looking forward to the video 👍
@@teenagefishman something I didn't realize until I started going over the installation last night is the Canbus version even has a tmc2209 on board so it frees up a stepper driver on the motherboard! This thing is cool. I'm working on a setup video because it can be a bit tricky. For first time users.and it's only for klipper.
@@StackingLayers Awesome, that's handy to have the extra driver. Only having support for Klipper is a bit of a limitation at the moment - I was going to convert to reprap. I might give kipper a go though. You inspired me, I just bought myself a Hermit Crab :P
7:10 This information came late. Printer is already disassembled and I need a new belt now. Ender-3 Pro for me.
What is the wight of the whole unit ?
I never thought to weigh it until after it was all set up, but I can weigh the removable setup along with a second tool plate to get a rough estimate if that interests you.
Hey could you help me a little bit my biqu b1 is printing wierd could you give me your cura setup pls?
I use the stock B1 profile that is built into Cura. I just adjust temperature and speed depending on the filament I choose.
how has it been the performance since you made the upgrade, is it worth it ???
Performance wise it works perfectly. It's very stable and makes changing out tool or even just working on them a breeze. As for is it worth it, I would say yes, unless you have no desire to swap tools. But even if you have just one tool it is a more sturdy mount than a printed plastic adapter. For example, I see many in search for a better mount to print for the BIQU H2 extruder while mine is sitting there solid as a rock.
@@StackingLayers I'm thinking about getting this just for that reason. I've tried the h2 adapter print in different materials and it just never seems sturdy enough. I also end up with the two screws that hold the h2 to the mount working loose over time. This seems like a good option, even though it's overkill for my needs
@@davidhaas2528 overkill perhaps but it also opens up future opportunities like adding a vinyl cutter or laser engraver to one of the other tool plates.
Great video, can yo do a guide explaning how to install linear raíls bro?
It's very easy. Just print some of these alignment tools ( www.thingiverse.com/thing:3383221 ) and use M3 screws with t-nuts ( www.amazon.com/dp/B01FOC6A70/ref=cm_sw_r_apan_glt_fabc_9ZSGB6NWC9V8J1ZBMSQM ) to fasten them to the gantry.
@@StackingLayers Did you remove the second screw from the x axis? "the middle-left one i mean xd"
No, it wasn't necessary. The holes in the linear rail didn't fall in that spot.
you have the link of the group to post please thank you
Actually after seeing your photos, I see you have already posted in the H2 group. 😊
@@StackingLayers yess
@@StackingLayers I posted on the h2 group and added photos thank you
Link Stl Fan+Bt pleas
Link is in the discription
Strang tie got recommended to me and it's a year old ATM
Probably something the algorithm thinks you would like based on what you have been browsing. None the less, thanks for taking the time to comment about it 😊 Hopefully you enjoyed some part of the video.
@@StackingLayers hey no problem man It was definitely interesting I've never seen that type of tool head before
Its pretty nice. Its a solid setu, especially on the linear rail. I have a CANbus version too which has a tmc2209 and ADXL built-in, along with the heater, temp sensor, BLTouch ports and some neopixels. And is run off a single USBC cable.
450mm rail for a chiron only cost 35$
How much
Keep in mind that there are 2 versions. This is the basic version. m.aliexpress.com/item/1005003319733040.html

MGM12 HIWIN
A Hiwin is what I should have bought. I went cheap and learned my lesson. I'll change it out sooner or later. Luckily I was able to get this one moving smoothly.
Спасибо тебе большое за обзор 👍
good evening I sent you a message and photos on your instagram
Looks like they finally showed up on IG, I sent a reply. Things look good in general. I do recommend getting ferrules on the ends of the wires though. They give a better more secure connection
@@StackingLayers Hello would you have a link for the electrical pods to use to make your connection to the hermit crab thank you
Are you talking about the ferrules, things are the end of the wires? If yes, it's good to have a kit on hand. I recommend the HSC8 6-6 crimpers m.aliexpress.com/item/1005001552393630.html?UTABTest=aliabtest300080_422159&_randl_currency=EUR&_randl_shipto=NO&src=google&aff_fcid=6e6614f195714c1e8a71358ba5708c84-1659354329640-02066-UneMJZVf&aff_fsk=UneMJZVf&aff_platform=aaf&sk=UneMJZVf&aff_trace_key=6e6614f195714c1e8a71358ba5708c84-1659354329640-02066-UneMJZVf&terminal_id=a7fa3c3dbadb4e8590764ff87be9c2c5&OLP=1083300208_f_group0&o_s_id=1083300208&afSmartRedirect=y
