Also, because the “hanger” on Ryan's original was a teensy bit too tight to fit on my ¼" plywood strut (which is probably thicker than it‘s supposed to be), I widened the hanger's reach by 1.5mm.Also, I have added a choice of bases — one with and one without accommodation for a 40mm cooling fan — in case someone already has one on hand to use, or considers it important enough to get one and add it.I am astounded with how much smaller this case is than the ones for the BTT SKR.I'm currently printing mine, but below is a preview from 3D renderings. FAQ:- - - -Q: Where can we buy the Jackpot CNC controller board?A: You can buy the Jackpot CNC Control Board (a FluidNC board, which is GRBL compatible) here: https://www.v1e.com/products/jackpot-cnc-controller - - - -Q: Which cooling fan did you use for this board? A: I used a super quiet Noctua brand 40mm cooling fan. Here is an affiliate link to the one I am using: https://amzn.to/3ubq2YY - - - -Q: One of the case base options has a spot for a 40mm cooling fan. Where does that get wired to on the Jackpot board?A: One of the easiest and best ways is to not connect the fan to the board, but directly to the power supply that feeds the board, since the volts must match anyway. Nevertheless, I connected mine to the board. The Noctua fan that I used runs on 12 Volts. However, the method I used can work with fans made for either 24V or 12V. — The key is that your fan's voltage must match the main power supply voltage. (Most people will be using 24V power, so that would mean the fan needs to match the power supply, at 24V.) — I connected my fan straight to a spare “MOSFET” port on the Jackpot board (which, again, will match the power supply, presumably either 12V or 24V), so that every time the LowRider gets switched on, the fan comes on. It doesn’t do temperature monitoring for going on and off. It stays on whenever the LR3 is on. It was simpler for me to do it that way. Please see the port options highlighted on this schematic:Q: How do I enable / switch on the MOSFETs on the board?A: Click here for… Details for switching on/off the MOSFETs via either Web-UI buttons or in GCode.- - - -
