Or if youhave a 3d printer take one off of it.
Tampa Florida, Nathan. Iāll be driving up 75 hitting 10 in the next few days. Iāll wave when I drive by lol
I donāt have access to everything in my shop of course while Iām gone, but I did throw the jackpot, power supply, some wires and a couple of steppers in my bag. I probably wonāt have time to fool with It until I get back up north but I think thatās a great idea Riley. Who has a step for motor Nema 17 that they are certain works with the jackpot and also has A part number I can order it from Amazon with. if one of you guys has such a thing, and you know the pin out, then we can do away with human error and or misunderstanding on my part by using the known pin out and known stepper with the known jackpot board.
Iām still going to retest all the pins and write it down for you guys as soon as possible along with the string of other possibilities that have been suggested in the last day of the half

well, I am sorry, I do not have a jackpot, but I would think this one that ryan sells will work!
Can anyone verify?
Thatās true.
I have multiple Jackpot boards, and 15 of those steppers that ryan sells. I just got through testing every single V1 stepper in every port on three different jackpot boards. All worked, 100%, no issue.
No need to frantic order from Amazon, find a craigslist/marketplace cheapie used printer.
Iāve also run steppers that came out the following applications interchangeably on Jackpot, SKR Pro 1.2, RAMPS, and Rambo boards:
- NEMA 17s from two different generations of Lulzbot printers (AO-10x series and TAZ series).
- NEMA 17s out of a Colido X3045 printer.
- NEMA 17s out of many Flashforge, Qidi, Creality, and no-name bedslinger printers.
- NEMA 17s out of a Anycubic Chiron.
- NEMA 17s out of a Rigidbot Big printer.
- NEMA 17s out of two generations of Solidoodle printer (Solidoodle 2, Solidoodle workbench dual)
- NEMA 17s on a JL-1 laser.
The only thing Iāve ever had to do in order to make these work is to ensure that there was good continuity and isolation to the coils. E.g. pins 1/2 and pins 3/4 are correct coil resistance and there is an open circuit between the two coil pair pins.
Of the collection above, three or four of the motor sets needed to be re-pinned as they did not match the 1,2 and 3,4 pin pairing for coils, and in every case those were 6-pin connector steppers.
The only steppers that Iāve found that were trouble using were:
- Stepper set from a Sherline mini mill (coils are wired to a weird dual center tap unipolar scheme.)
- Steppers out of a no-name 500mw Chinese laver engraver (looks like something using recycled DVD tray steppers!)

Thanks Riley. Itās on order from V1. Iām not certain but I think itās coming from California so I should have it here in Florida within a week. Does anyone have info on A stepper that they are using with the jackpot that I can order from Amazon so it can be overnighted?

I have a box full of steppers from old disassembled CNC machines to choose from at the stop and the only ones that I can get to work with this board are the two that Iāve mentioned in the previous posts. The reason for ordering in From Amazon would be the ability to overnight, but more importantly, being one that specifically one of you guys knows the pin out of.

You could go with the one that Ryan links from the V1 documentation. The caveat with any Amazon link is that it often times get silently swapped out on the Amazon end with a different product.
At any rate, from the LowRider documentation here:
https://docs.v1e.com/lowrider/#specialty-parts
There is an Amazon link for the StepperOnline NEMA 17s that match Ryanās spec.

To summarise:
- It seems that you know the steppers you want to use work as confirmed on other control boards, and
- you know the jackpot works as confirmed by using other steppers.
- But the combination of a certain stepper and the jackpot doesnāt work. There seems to be nothing particularly unusual about the steppers you are using, so that points to either a connection issue or a setting issue.
- I donāt think you have yet confirmed the wiring measurements as requested by @jamiek and @MakerJim or perhaps you have but I missed it.
- Also I suggested you change the settings to reduce the power to those motors. The change in angle per step seems like it will affect accuracy but not operation. You seem reluctant to change any settings on the jackpot, but Iām not sure what is to be achieved by trying even more steppers - you already know the board works.
Also it would help if you could post directly - did you try this yet:
Did I summarise that correctly?
Yes thatās more or less the situation, Rob with a couple caveats. Iām not opposed to making small pointed settings changes just not large sweeping changes. So Iām going to change the few things that have been mentioned in the last two days one at a time, testing and then setting back to original before I try the next. I would have done it already but Iāve been in airports and traveling for business for the last two days. I brought the jackpot and the few items needed to run basic tests because it is a high priority right now but annoyingly it will have to fit into my schedule instead of everything working in around it.
As for the stepper I purchased from V1 (should be here within a week) and the one I hope to purchase from Amazon as soon as one of you guys directly says yes I have that stepper, itās model _ _ _ _ _ _ _ _ from _ _ _ _ _ on Amazon so you can have it overnight freight and yes I know the pin out and yes it works on the jackpot. ( btw all steppers should and Iām sure do work on the jackpotā¦ clearly Iām doing something wrong. I hope everyone is aware that I know that and Iām not blaming it on the board. The board is great. I digress) Those two purchases are more or less to take my judgment, ability, understanding Or otherwise flawed procedure out of the equation. Notice, I have not asked anyone to simply trust my ability to have pinned the steppers out correctly with the ohm meter because you donāt know me. After all I could be a complete moron and itās completely understandable that Im not given the benefit of doubt until Iāve shown Iām not a jackleg. I get it.
Soooā¦. By doing it this way I canāt really lose here. Either way this plays out I get what I needā¦ a working machine. Itās possible that I donāt know how to operate an ohm meter. Using the known to work, known pinnout stepper from Amazon and then V1 when it arrives will tell us that and also give me what I need which is a working machine.
Ifā¦. Ifā¦.If I get the known to work and known (by one of you guys) pin out stepper from Amazon and V1 and it does not work then we know its a setting or something else and I eventually get what I need which is a running machine but nothing moves forward until itās 100% decided itās not a wiring issue.
I understand that writing down the high/low readings of the ohm meter is going to achieve the exact same thing as the above Amazon known pin stepper test. However I have lost confidence that, that is going to result in anything but someone saying well you must have written it down wrong 
Yes I will 100% will be writing down the ohm high/low readings anyway as soon as possible that is the first thing on the list.
I have several requests to try then note various things as soon as possible and I will be trying each one and reporting.

o.k. so somewhere I missed that the board works with steppers you already have.
I am very sorry I recommended buying one.
I think I am going to step out before I recommend something else that is not necessary.
I found this board on Amazon, and saw this in the picture:
The āB- B+ A- A+ā indicates it is expecting adjacent wires 1, 2 and 3, 4 to be the coils.
So if all the motors (not just the pump) work with this board then those motors are also wired this way at the 4-pin plug. This should also work on the Jackpot board and I think it can rule out ABAB wiring (or BAAB).
Also note that you should not plug or unplug motors while the board is powered. Some boards/firmware do not energize the motors until you begin moving. FluidNC/Jackpot energizes the steppers right away on power up. Plugging and unplugging the steppers while energized can damage the drivers. I donāt know if this is guaranteed to happen or if it is just a precaution so unfortunately I canāt speak to the likelihood of this being an issue.
Itās a planetary gearbox.
Yes and all instances of this model number (17HS13-0404S-PG27) I can find online show it to be directly wired, rather than a 6-pin connector, but all the sellers I found have āstepper onlineā convention where green and black are one coil and red and blue are another coil.
So that further supports that the wiring is probably correct, although the 6-pin connector does raise some doubt.
We should also keep in mind Ryans suggestion way up thread that the initial test configuration should probably be a V1 default config as thatās what is tested with for every Jackpot that leaves the shop.
It wonāt have the correct configuration to run the different machine, but itās known good in that if you plug a stepper into X and jog the axis, it will move the stepper properly.
From there making a full custom config.yaml makes sense.
I ordered it even before he posted it someone else had sent me a link. Re-read what I posted. That is about the Amazon one. The V1 stepper wonāt be here for a week which is totally understandable as I think it comes all the way from California. Trying to find a known stepper from Amazon that I can have overnight or even same day shipped.
Re-read my posts. About 4 times I mention that I changed the ymal config back to the non altered original

Yes. I read what you posted.
you said you were waiting for confirmation of a stepper that works that is available on Amazon
the link that @MakerJim posted is an amazon link, for a stepper that is known to work.
Againā¦the link that @MakerJim posted is an Amazon link, to a stepper that works.
You posted, after @MakerJim posted the link, that you were waiting for a linkā¦ Iām not sure where the confusion isā¦
