NymoLabs Wireless Probe with Jackpot

Has anyone tried using one these wireless Z-Axis probes with a Jackpot?

It looks like it would be quite simple to get working with a Jackpot. I should receive one later today and will share how it goes.

This thing works great. Extremely nice to not worry about wires and clips.

Took about 10 minutes to install and is a great quality of life upgrade.

Receiver installed - three wires (GND,5-24v,SIG).
Can be mounted via double sided tape (included) or attached via the magnet on the back.

Transmitter/Probe - trigger height listed on side - worth measuring again yourself to make sure the numbers are accurate.

Pretty sweet so far. I will use it for a bit and report back.

Be careful with the z axis probe speeds, that thing has some latency

Can it pullback and slowly reprobe to make sure it is correct like all the other axes when they home?

Yes, but you do it with a macro. You would probe initially ā€œfastā€ in case you are 120mm away, then move up 5mm, probe again slowly knowing where you are. So you do not waste a bunch of time.

I have my probe set up that way. Works great. But it’s just part of my start gcode.

The latency isn’t too horrible as long as you are being reasonable with your probing speeds.

When I have some spare time, I will crack open the transmitter and setup some latency testing on the o-scope and get some real numbers.

@Jonathjon - Would you mind posting your startup gcode for how you have it working? Great info to help demonstrate how to do fast probe/slow probe regardless of probe type.

This is what I use. I am not the one that came up with it. That credit goes to @Michael_Melancon

G38.2 Z-110 F200 P0.5 (probe down set thickness )
G1 Z5 F900
G38.2 Z-10 F20 P0.5 (second probe for accurate thickness)

How you wire it to jackpot?

Installing the New Probe

Remove the Old Connection
Disconnect your current wired probe from the Jackpot board.


Prepare the New Connection
Gather either pre-wired Dupont connectors or the tools needed to crimp them yourself.


Wire the New Probe
Connect the three wires from the new probe receiver to the Jackpot board: Use the bare wire to JST plug included with the new probe.

  • GND (ground) → gpio36 - G (Gpio GND) (Lower Pin)
  • SIG (signal) → gpio36 - S (Gpio SIG) (Upper Pin) (Look for the row with the S beside it)
  • PWR/V-in (power) → 24V power supply input

Complete the Installation

  1. Plug the probe receiver into the plug you wired above
  2. Pull the battery tab from the new probe
  3. Gently press the probe—the Jackpot’s LED should light up
  4. Verify you hear an audible beep from the probe

Installation time: 5–10 minutes

Thanks for wiring info got it now.

Just a note I had to look at your Picture again your running a Jackpot1 the description threw me off for a minute ā€œtop pin, bottom pinā€. I’m mounting to Jackpot3for lowerider4, I have a Jackpot1 running a laser.

Yep, I don’t have one of those fancy pants Jackpot3 boards. I’m out here slumming it on my grandma’s Jackpot1 hand me down. :disguised_face:

Which is basically the same. :smiley:

Jackpot 3 just sounds much better than having a Jackpot 1.

Isn’t the Jackpot 3 three times better? lol.

It looks like the wiring instructions are still applicable to the 3 with the exception of describing the GND as being closest to the middle of the board.

On the 3, it would be the pin closest to the edge - still the ā€˜bottom’ ping for GND and top for SIG.

I will tweak the instructions slightly on the directions to make it version agnostic.

Those are great instructions, and it’s also a nice touch to clarify that you as a person created and verified the info. Well done!
