BIQU Hermit Crab 2 unbox and Canbus set up

[@eastcoast8435]

Don't forget... do not put the ferrules over the soldered ends, clip until you have some nice bare copper for a clean connection.

[@eastcoast8435]

Sorry, forgot to say in my previous comment. Thanks for the detailed vid. I didn't know how much I wanted this until now. 😆

[@StackingLayers]

It is a pretty cool setup. I absolutely love the original one and now this one is thinner and lighter.

[@glenndhooge6787]

your videos are indeed on the long side. but they hold such great educational value on how to lean how to properly instal all these things.

[@StackingLayers]

I agree, my videos are too long. I'm working on trying to get the same info but in shorter form.

[@bleinahtan]

@@StackingLayers Yeah you could make a short version with all the crucial steps, but it's real nice how you explain and cover all the smaller details of what you're doing along the way. Makes it super beginner friendly even if you aren't familiar with Linux!

[@StackingLayers]

That's my main plan, to make it a learning experience. I hope in the end, the person watching can have a better understanding so future set-up and trouble shooting will be easier.

[@62arts]

i think that is video is way.... way... under rated. Considering the masiv lack of documentation/videos on this type of accesories/systems

[@StackingLayers]

I agree. It's a fantastic setup.

[@62arts]

@@StackingLayers by the way, do you know if there is on optiun and how to assign automaticaly profile for each plate? ex: one plate for 3d printing, 1 for laser cutter and one for pen cutter, or something like that.

[@StackingLayers]

@62arts I'm still working on figuring out a good solution. The major firmware makers don't natively support that. But I believe there's a way to get klipper to work and you'll just need to uncomment and comment out include profiles. There's probably even a way to make a macro fo it.

[@bloodontherisers73]

Hey Stacking i noticed that you added an extra period in sudo nano command after the word interfaces in your description above. Threw me for a loop.

[@StackingLayers]

Oh man I didn't even notice I did that. Thank you for pointing it out to me. It's now fixed.

[@mattiamusica3059]

Hello, I saw some videos of your channel that talked about the btt pi 1.2. I already installed it and I want to manage the printer with a camera but I can't do it. Can you make a video about installing a cam on the btt pi? Thank you by the way, great chanell

[@natereinhold6180]

I believe the squiggly line is called a tilde

[@StackingLayers]

That is correct.

@@StackingLayers stupid name, that's the only reason it ever stuck

[@redline6871]

Could you set it up in order to start a print pause print switch tool heads same h2 extruder but different color and continue on with the print. Not sure if that would work but the idea popped in my head would be pretty cool like a idex but just by swapping tool heads?

[@StackingLayers]

It would probably work, but hot swapping can be risky with certain components. It would be very important to make sure all items are on the tool side are not engaged

[@joshmaxwell8767]

I'm having an issue with mine where it fails to read the sensor state of my BLTouch. There appears to be a short between Probe Signal on GPIO24 and ground even before the probe is attached. If it's not too much of a hastle, could you please check whether that is also the case for you? It would help me a lot! I'm pretty sure that mine is borked though.

[@StackingLayers]

Definitely no shorts here.

[@62arts]

Me again, by any chance, do you have a .cfg for hermit crab 2 can config ?

[@StackingLayers]

This is the generic.cfg you will need to query the UUID and ser that of course. github.com/bigtreetech/HermitCrab/blob/master/HermitCrab2/sample-bigtreetech-hermit-crab-2-canbus.cfg

[@lexdysic416]

How long is it gonna take for somebody to rig an automatic tool changer with this thing? I'm working on a stealth changer myself.

[@StackingLayers]

This wouldn't be an auto tool changer, but that would be a cool mod to put an actuator of some sort.

@@StackingLayers Us makers aren't always concerned with what a part is intended for. Its far more fun to make to do something its not...heh

[@62arts]

for 3 days now i'm trying to make the hermit crab 2 comunicate with manta m8p. and for the life of me, i can't make it work....

[@StackingLayers]

Have you double checked that the high and low lines are in the correct order? And then the 120r jumpers are in place?

[@62arts]

@@StackingLayers i have switched them 4 times. And tried multiple time with resistors, without. The can0 cannot be found/initialized

[@StackingLayers]

@62arts the resistors must be in place for a steady signal. Other things to double check is that all the bitrates are the same for the MCU firmwares and on the host in /etc/network/interfaces.d/can0

[@62arts]

@@StackingLayers the issue is that for the life of me I can't make can0 appear in ifconfig, and all of the python scrips give errors.

[@StackingLayers]

What is in the, etc/network/interfaces.d/can0 file?

[@rbuschy]

Someone please come up with a BIOS for these things. So average people can set these things up without having to learn how to program. They found a way to sell stand alone Klipper Screens, surely they can sell these with little ROMs for configuration settings.

[@StackingLayers]

That wouldn't really work. You are flashing firmware to the flash memory of a micro controller, and that boots and runs at power up. That's why I like installing katapult. It makes future firmware updates quick and easy. Even the so called stand alone klipper screens or pads are just screens with a host computer built-in or attached like a CB1 or CM4 for example with the Pad7 it's all set-up for you but you'll still have to know how to do updates and flash controller boards from it.
