Hello to you all from the UK. I have recently got my hands on a partially built / partially printed LR3 & have been told it needs an MKS Tiny bee board. Googled it & still not a clue what to get. There appears to be all sorts of different ones. Any info would be much appreciated. Also are the end stops just micro switches or something special?
Thanks in advance & be gentle.

Welcome to the community! I have just recently build LR3 
I went with SKR PRO board, you could go with Ryanās board named Jackpot. I personally never heard of MKS Tiny bee board, but Iām not expert 
Endstops are just end switches - those with little arm
Greetings!
Welcome to the V1 community forums.
Where in the UK are you?
For a new build or to complete a build Iād recommend a Jackpot V3 or a Jackpot V1.
MKS tinybee isnāt the board we would recommend.
It doesnāt have full UART control of the stepper drivers, and is a bit of an oddball for a V1 machine build. We do have community members successfully using them, but why start out with less capabilities for not much difference in price?
There are other boards like the SKR Pro, but as a general recommendation itās the jackpot.
Does your build already have a power supply?
Nothing special, just normally closed snap action microswitch endstops.
If you donāt use one of the ones called out in the documentation, pay attention to the mounting hole configuration and size. Avoid āfancyā endstops with circuit boards and avoid optical endstops.
We love helping our community with their builds and projects. Ask away.
Feel free to open a build thread for your project finishing up the LR3.
We love pictures, we love build threads.
Ok thanks for that, Iāll scrap that tiny bee when I collect it next week.
Iām in Chester.
I have loads of microswitches so that wonāt be a problem.
Not sure if it has PSU with it, But he said it needs (in his word) MKS board, end stops, A battery for the router (I wonāt be using that though) some struts printing & some belt locks printing.
Which SKR or Jackpot board would be best for me then.
Not sure if it matters but Iām a Fusion 360 guy for Prusa stuff & I have watched a lot of YT vids of guys using that for their LRās. I want to use some sort of screen for controls or even some form of remote if that makes a difference.
OK, get a build thread going for your machine and weāll help as we can.
Should have said Iām new to Forums also !!
Would that be in the your build section then ?
Didnāt realise there was a shop on the V1E siteā¦Doh!! There will be import duties I presume to the UK. Is there any distributors this side of the pond?
You can order from elecrow
Yep.
Jackpot V1: Jackpot CNC Controller FluidNC V1 Engineering MPCNC LowRider CNC
TMC 2209 drivers: Amazon.com
ESP-32: Amazon.com
Edit: Ryanās worked really hard to have options for builders worldwide, despite the insanity weāre living in.
Edit2: I donāt think Jackpot V3 is yet available from Elecrow, which is why I linked the V1 board. V1 is still a perfectly suitable board, primary difference is removable ESP-32 on the V1 and some improvements in connectors and IO configuration for the V3.

Thatās tickled me. Thanks Guys. The TMC2209 is Out Of Stock (Iāll search for more) & the ESP-32 has DD & UE version ? Which one ?
The forum adds the silly titles. I must answer a lot of questions
Oh the silly games Amazon plays.
You want the 32E. it should say ESP32-WROOM-32E on the main chip.
(Old images taken from the saved reply pile)
I thought the genuine V1E ESP-32 board was on elecrow, but Iāll need to go look for links. (Not seeing it, perhaps not available there)
Maybe.
That one isnāt an espressif made one, and may have a USB-C connector.
Some of those are a couple of mm wider than the ānormalā ones. It can still go in the jackpot, though in the worst case you have to slightly bend the headers on the jackpot and the pins on the ESP32 to fit.
We use ESP-32s with CP-2102 UART chips, but some manufacturers use a different UART chip. It can still work, just need the correct drivers to be able to open a FluidTerm console or to use the installers to put FluidNC on it.
I think a 380 just flew over my head
Totally lost me then. How about I pick it up next week & verify everything I need then we will go from there & I can get it going before Christmas hopefully.
I donāt think I did when I ordered direct from the USA. Shipping was a fair bit but I ordered a few extra bits n pieces to make it worthwhile.
Oh ok cool thanks. I was thinking it might just be easier to go direct to V1E. How long ago was it you got yours ?
2023!
I know sending stuff TO the USA has got a bit mad but the other way hasnāt changed much as far as I know.
Ok thanks. Iāve just ordered it from V1E. Shipping was Ā£26. Not bad.
I have a tiny bee. It is ok. I only have it because i had the steppers etc, and had a gift certificate. Trust me I still wish I went with the board from Ryan. Dont get me wrong, it works, but if you are buying steppers look at what it is and then look at Ryans. The only way it can maybe compare is if you are not in the u.S.
