After reading and watching YouTube vids and wanting to try out ugs ive decided to scrap the skr pro for a fluidnc board my first choice would be the jackpot but at £100 ish with shipping and customs a bit out of my budget so looking at the tinybee at quarter of the price. unless anybody can reccomend another route?
Which stepper motors are my best choice? I already have a new set of 2209’s.
Duel endstop config is this possible.
Any adaptor boards recommended?
Any sample config files to get me going in the right direction?
Thank you for taking the time to read my post.
I have a tinybee in my LR3 with some tmc2209 and it’s working great
Dual endstops, laser, and it still has a few gpio to spare…
Some pins labelling can be a bit confusing but all in all it’s a great value for the price
The big downside though is that you can’t adjust the driver’s current through software

Would you mind sharing your config file and pin layout?
That would save me a big headache:)

Note: I’m using 1mm pitch Z screws, so you may want to adjust the steps per mm there
One thing I’d like to change is the wiring of the fans I used for the case, There’s no point in controling them, so you might just wire them in parrallel with the 24V input
I bought a 0-10V converter baord to control the spindle VFD but I didn’t get around wiring it yet, I’ll update this if I ever end up plugging it

Thank you its much appreciated
Hi Simon I moved to the Jackpot from the SKR Pro - I just had so many problems with the SKR boards over the years. The Jackpot has been a huge improvement. I also ran the MKS Tinybee as recommended by @Fabien but I do like to be able to turn up the current in the config as they run pretty cold here in Scotland.
I have never paid any duty on orders from Ryan, maybe just lucky? Its good to get the touch plate, and definitely that collet for the Makita - there is nothing equivalent here in the UK at anything like Ryan’s price. His router bits seem superior too. All in all, the duty is a concern and the shipping is a cost but I think its worth it, if you stock up on a few bits. You can feel good about ordering from Ryan too.
There is also a route to getting your own Jackpot made and shipped - there is a thread about that somewhere.
Good luck
Rob
p.s. I grew up in Sheffield and spent most of my childhood summers in Skegness and Ingoldmells, back in the 80’s, my Gran had a van there. Some of my happiest memories.
Just to chime in on tinybee vs jackpot and duty…
I initiallly bought and installed the tinybee
Then I won a jackpot as a prize from a contest Ryan organized
When I received the package I had to pay taxes on shipping even though it was a free gift >_< (20-25€ mind you…)
I never got around switching to the jackpot and still run the tinybee because there’s been no limitation with it that could justify the hassle and downtime 
The jackpot looks a lot nicer and tidier, and adjusting voltage on the board would be great, but that’s mostly “quality of life” improvement
If you buy other stuff from v1 and cumulate shipping though, it’s great value too

me again haha do you still clip or bend the pin on the 2209’s ?
I think it depends on the particular drivers you get
I didn’t clip or bend any pin on mine
above you state you were going to buy the jackpot, did you buy Ryans board or the tinybee, or something else. That will help others to help you.
I ordered my Tinybee on Aliexpress as a kit and it came with the drivers and the screen (which wasn’t used). The pins that you would bend don’t go into anything on the tinybee. You have to set that pot though and its a bit fiddly. Mine is out of the machine at the moment so here’s a pic.

yeah the pots are terrible… btw the way, you need to shut the power off before you try and adjust them unless you like your board well done… ask me how I know >_<
What do the pots need setting too?
There’s a small pot/resistor on top of the drivers that sets the VREF current
sorry yes i meant what should they be set too ?
See chapter “How to calculate VREF” for a complete answer
Short answer: 0.80V-0.85V is a standard value
