Jackpot3

Thank you! I have been busy elsewhere and not finished up wiring my MPCNC so I haven’t even tested the JP2 yet. I was very confused when I saw the shipping notification for the JP3. I had to verify that I hadn’t been drunk shopping again.

HAHAHAHAH, I made a mistake so I made it right. I appreciate you being an early adopter…and now you have a spare board to make something cool!


Analog signal on the 5v output looks amazing on all 4 ports. I will get ready to ship and sell these Bad Mama Jama’s!

Should change the shop’s LR picture to the 4 while you are at it. It’s only been a year though… :face_savoring_food::sweat_smile:

okay I changed a couple of them

I am going to put up 10 more just to make sure everything is good before I unleash them all. Jackpot3 CNC Controller – V1 Engineering Inc I still need to make all the info pages and all that but I want to cut out some more table parts first. No rush to push these out before we get a couple other confirmations. I have been using my beta board a lot and have no issues currently.

Sweet!

New board looks great! Thank you for generously sending me the latest version! :folded_hands: Personally like the new wider pitch screw based connectors.

Quick check… @vicious1 are the vmot and gpio connectors oriented as you intended? Should the connector shells be mirrored instead of same orientation? Currently can’t insert two pairs of 2 pin connectors. I’m behind on this topic, maybe people needing to use vmot and adjacent gpio are expected to use 4 pin (2x2) connectors that will fit there?

I don’t know why, but I like the sexy black heat sinks more than I should.

Hoping to play with the board soon!

The 5V output and Vmot channels that are inline share a GPIO, so you shouldn’t ever need to use the two together as they would be controlled by the same thing. In the rare instance that you have something that needs +Vmot power as well as a digital control signal controlled by the same GPIO, you’d be better off either using an external relay/SSR driven by the GPIO and a buffer or an optoisolator or similar driven by the Vmot output.

Edit: To be clear, there’s no reason you can’t use both together, other than that they would both be switched at the same time. There are other configurations of plug that may also work for that scenario:

Each pair is one pin so you choose high or low voltage as the output. In the firmware you choose analog or digital, High voltage is digital only (or extremely slow analog).

I will do my best to make this very clear in the docs in the next day or two (as soon as the table I am making is done).

I can get blue and balck easily, the other colors are harder to come by so I am sure I will try out a few combo’s but probably mostly black heatsinks to match the black plugs.

I presume the Analog setting is actually PWM? I’ve seen similar nomenclature in the Arduino API and I’m not sure I’m a fan of conflating the two.

Any colour you want, as long as it’s black! Worked for the Model T well enough.

Unfortunately FluidNC config conflates the two and you configure analogN=gpio.x to get a PWM output.

Blech. Very much not a fan of that approach. Oh well!

what is the best way to order this board if I am in the canadian market , trying to avoid tariffs or I stack with SKR boards from china . I really want to try the Jackport 3 since I have always unsed the SKR , on one note I am not planning on doing any laser so is the jackport good enought ?

Can you have step/dir output as well so that we can use closed loop steppers or servos (clear path) pleaaaaaaaase?

Step/Dir does not help you with closed loop, it still needs the pinouts for the encoder. You need external drivers for that.

I have no way to avoid import tax from your government, sorry. You can have the board shipped from the US, or in a couple weeks from China Direct.

Again, that’s not accurate. I frequently buy US designed electronics manufactured in China from US suppliers and pay no import taxes when the shipment is accurately labelled.

HS code 8537.10.91.30 has no Canadian tarrifs for China as the Country of Origin and USA as the Country of Export.

As of September 1, 2025 there are no tarrifs on the same products of US origin, either. Brokerage fees apply, though… so we’re back to USPS->Canada Post being the cheapest option at $9.95.

Elecrow works, too. Brokerage still applies, but the product may be cheaper if the Elecrow price is cheaper than the US-based price.

I have external drivers, steppers etc, I just need to know if the jackpot2 can drive them

No. It has been tried before but there’s never been a solution.

Ok. I think I can use them on the jackpot 1, since I can pull the drivers and use enable, step, and dir for the external drivees

It has been tried on the 1 and there hasn’t been a solution. In this regard they are all the same. Search the forum for it, you might find the thread. :smiley:
