Okay, the new DuPont/JST-XH kit got here and it’s all re-crimped and re-wired up. These new connectors are WAY better than the prior kit and the original DuPont shells. My giant man hands and those little bitty JST female connectors are SO much fun together…
I’ll see if I can hook it up for testing once the mounts finish printing. I decided to go with the 3D printer instead so I don’t have to paint. It’ll be done tomorrow afternoon sometime.
Looks awesome!
I just got these btw, absolute game changer for crimping these connectors. Never again will I use a ratcheting style crimper. Little late for you, but maybe in the future!

+1 on that. I crimped my whole Voron build with it and it did not fail once, even with some „not so great“ connectors.
Got my case supports finished and mounted and the lid locked down. It’s going to sit on the rear rail of the LR3 like the original controller case and sit parallel to the table surface, but this one will face the outside so I can easily read and work with it from the side instead of the table head.
Still need to mount it and test all the connections this weekend and we’ll see if I need to redo any of the wiring.
I see a lot of M119, M106/M107, G38.2 and directed movement commands in my immediate future…
I also made a few z-axis supports to keep my gantry from bottoming out whenever I turn the machine off for storage. I’m starting with a 65mm height and we’ll see how that works. I guess I could have walked out to the garage and busted out the calipers, but I was feeling lazy…
I use these created by @SlowRider. They work great.

I’m printing a set in the morning and will try them both this weekend.
Ok, got everything reassembled and mounted… as soon as everything checks out, the glue gun will make an appearance….
End-stops, check!
M106/M107 IoT relay control, check!
TFT connection, check!
Stepper control, FAIL.
I’ve got zero movement on any axis, checked all my new cables for the steppers and end-stops and the connections are good.
I checked the motor power crossover and it looks good. I checked the voltage across the three fuses and got nothing on any of them. My 3.3, 5 and 12V lights are all on…
From what I gather, a reversed stepper connection should still power up and move, just in the wrong direction, so I don’t think that’s an issue I can test yet…
What else should I be looking for?
Not sure but watching.
No voltage across a fuse when the system is on means the fuse isn’t blown.
I’d start with a close-up picture of your board/motor wiring crossover setup.
The one linked uptread doesn’t allow one to confirm you have +/- correctly installed at the terminal blocks.
Next, use your DMM in voltage mode with the borard power on and report the voltage you measure across the board inlet power + / - and also the voltage you measure across the motor power + / -.
Are you running your TFT in marlin mode or touch mode? What messages do you have on the board?
How are you checking motion, with commanding from the TFT, or via USB or ??
Edit to add- in the picture above, the top + connection has a black wire installed below the red top wire.
That’s at best really bad practice, at worst you have flipped power to the motors.
Unfortunately that black wire you see under the red one is my power supply connection and it’s black on both sides.
I measured the voltage across the inlet power and the motor power terminals and I’m getting 24.4V on both.
I typically use TFT mode, and I’m getting appropriate responses from the M106/M107, M119, M115, G92 commands. On boot, I’m getting the “No printer attached!” message in TFT but that’s normal. In Markin, it’s saying “V1CNC 515DL Ready” but the X, Y, Z coordinates are flashing back and forth from 0,0,200 to ?, ?, ???.
Are there any any other messages I should be looking for?
In both TFT and Marlin modes, I’ve tried moving using both TFT and Marlin and by using the built-in movement commands as well as direct g-code.
I haven’t gotten to trying via USB yet as my Raspberry Pi doesn’t seem to want to load Repetier-Host, so I’ll have to drag a full sized pc out here for that part shortly.
UPDATE Dragged the wife’s laptop out here and connected and still have no control from either the built-in commands or direct G-Code from Reptier-Host.

If you manually command moves from the console, what response do you get back from Marlin?
It doesn’t give me a response.
Ugh… just broke down and ordered a new SKR Pro board… I was debating a Jackpot since everyone seems very excited about them, but don’t want to change too many variables at once. I guess we’ll see if it’s a board issue later this week.
Can anyone tell me what the advantages of the Jackpot are over the SKR Pro board? Also, will it fit in the same enclosure and can it use the same TFT?
The Jackpot is powered by FluidNC, which is GRBL compatible, which has some advantages over Marlin. Some of the most notable are:
There’s probably more but these are some that come to my mind.
It’s a smaller board; fits in a smaller case. You could fit it in the bigger case, with a printed adapter or some such. It does not need a TFT because of the wifi and built in WebUI, but a TFT could drive it, if programmed to. Speaking of which the FluidNC dev team is working on a FluidNC Dial pendant that has a touchscreen on the dial of it. This is still in development, but they are moving quickly with it. In short though, “can it use the same TFT” — no not unless some programming development was done.
I’ll probably invest in a Jackpot board if I ever find a laser I can settle on…. I really want one that I can run on this and my Snapmaker A350T, but SM is proprietary as hell. In the meantime, I just want it working again, so the new SKR Pro board that arrived should do for now.
I also pulled the trigger on an IDC Woodcraft Beast (1/4”) and Badger (1/8”) set. I know the LR3 likely won’t be able to pull off half the abuse I see them demoing these with, but I like the idea of a purpose built set of roughing bits. I’ll report back once I’ve had a chance to give them a go.
Those do look good. Actually just thought about getting one of those (not the badger, but a clearing endmill).
I still remember the first time using a roughing bit. You’re gonna be hooked

Garrett from IDC Woodcraft just mentioned he plans to stock the Muscle Chuck for Dewalt trim routers at 23:40…
I’d lose a little vertical space to get it in there, but honestly kind of excited…
