how to do it?

[Baddafin]

I live in Poland I am 16 years old and I go to a mechatronics technical school. I have questions I plan to build it from the first video the second one convinced me I have several 3d printers ender 3 pro disassembled into parts, k1max, a1combo, k1c, p1s. I also have a metal CNC milling machine and a CNC laser made of parts from ender 3 pro, maybe not all of them because the laser has a 125x80cm working area. I have parts from the list in the basket except for the motherboard and the work table and here I have questions what CHEAP motherboard to buy and what heated table? what to buy to modify the original design to make it work better, more stable B axis??? what to look for? thanks in advance for your help

what CHEAP motherboard to buy

The cheapest you can use (5 drivers) that supports RRF and has wifi (if you buy the supported wifi module) is the FLY E3 V2 I think

what heated table

You can find cheap PCB beds on aliexpress, this one is 220mm for example, you will need a slip ring of course and adapt the C axis for it

what to buy to modify the original design to make it work better, more stable B axis???

Me and some others did some changes, I know a guy who designed the B axis mount to be double sheered, my base is basically in one piece with the 24v PSU in there to give more weight to the base... so I think that's something we have to discover and tweak for ourselves and try looking for what other's are doing to implement on our builds as well.

My suggestion is to try reading the available discussions around this repository and try to look at active forks and such, you will get a lot of knowledge about the project doing so.

Warning: the Fly E3 V2 board linked above is probably a scam. I happened to order a scam board that never got delivered. I got my money back from Aliexpress, fortunately. The Fly E3 V3 is not produced any more. I chose the Fly E3 Ultra with ESP32Eth WiFi add-on. More expensive - but real.

Well, I received fine, and bought the wifi module after (from the same link). We are talking about a board sold on the official mellow store (respected store), and fly e3 v2 is well documented on teamgloomy docs as well.
