Alarm during a cut - Lowrider V4

Its me again! I’m sorry I’m posting nothing but my problems on here, and no cool projects! But I am once again having issues with my Jackpot Controller.

In the middle of running a program (everything was running smoothly), my machine alarmed out for some reason. There are no specific error called out in the log, so I’m a bit confused. Also, sometimes when I boot up the machine, I am met with alarm, but restarting the board has fixed that up until this point. Not sure if that’s related or not.

Any advise is appreciated! Thanks!

Hi,

What version of the jackpot?

Please post a picture of it all wired up.

Is your Vacuum hose grounded?

Hello!

Im using the V1 Jackpot controller running FluidNC v3.9.9. Yeah, my vacuum hose is grounded, just verified with a multimeter.

Also, my dust extractor and CNC machine are on different circuits.

That plug turned like that makes me think it has been over tightened and possible broke ground in there. I say that because I did the same thing with my original Jackpot and it would do crazy stuff randomly because of it. Once Ryan fixed it, all has been well for a long while now.

Just checked, and doesn’t seem like the case. The solder joint looks good from the bottom, no play in the connector, and I got continuity between the solder joint and screw terminal (even while moving the wires around).

is it as simple as trying to make a negative move? first alarm line says -57.960

post your gcode pls, that should not be 0,0, -57 i do not think

Ahhhh, what firmware is on that.

Use $SS in the terminal.

That negative triggered the memory. There is a firmware version with a bad arcs setting and if your endpoint is too far out it will have issues. If you are not on 3.9.5 or 3.9.9 you might as well update to 3.9.9 with jackpot firmware. Remember to write down your offsets.

@JR123 said he is using v3.9.9.

@JR123 Can you share the gcode? We can see if there’s anything funky with it. The bad arcs that were mentioned isn’t something that I think was ever fixed. I think some arcs can still cause issues. What did you use to generate the gcode?

I have been using ESTLcam to generate GCODE.

I would also like to add, I have probably done only 5 projects on this machine, all using ESTLcam.

Does anyone have any ideas here? At this point, I’m just considering getting the JackPot V3 and hoping that fixes the issue. I’m just a bit surprised that my JackPot V1 failed after only 3 months of light use…

HOLY Cow! There is ALOT going on in that file! Curiously where does it cut out at?

Right away i see your first operation going -x , where are you setting zero at? i myself usually let it stay in lower left corner.

Wrong: It finished the last drilling operation, raised up, jogged about 10 mm in the +Y direction and stopped.

I just checked and totally misremembered that. It finished this section: (No. 10 Part machining: Part 3), then froze up

The zero was set to the center of the workpiece.

heehee, that is what I was doing :slight_smile:

Is that the intended output, three circles with three holes?

The gcode looks fine from what I can tell.

Here is my suggestion. I think we have a random issue. Start the cut again in the air. Try it with the spindle off first, then try again with it in if it works.

Yeah

One large circle, two small circles? It does not look like it will fit on that material.
