Low Rider with Jackpot connection issues using usb

Software / Firmware Millmage / LightBurn
1

I am having trouble connecting via USB from lightburn to the jackpot. it had worked via WIFI but lag spikes make it unreliable (not surprised from forum comments) so I dug up a couple of usb cables and started trying.

jumping ahead

I do have what amazon called a long high speed data cable coming just incase my cables were “charge only”.

The back story

When I plugged in the jackpot I was first greeted with a missing windows driver to get it to recognize that there was something plugged in. before that lightburn did not see anything on the com port.

then I looked around and found a thread about startup sequences

power up an unplugged jackpot then connected to the pc. but no motion.

confirmed baud rate is 115200, no motion.

short of the cable being the issue, is there something i missed

Did you install these drivers?

yes, after I had installed those then the software was able to tell something was plugged in

Did you set the DTR option in Lightburn?

If you have a really long USB cable you should be sure it is one that has a ferrite bead in it.

A quick check and no I did not have that checked, after the check the fire button works (a full test after the work day)

Thanks

You may want to tag the post from @MakerJim as the solution, once you’ve completed your testing. Doing so will maintain the high quality of these forums by helping others searching on this same problem.

I think I have tagged it correctly. the first greyscale test ran nice no lag spikes with the usb connection.

not sure where to place this but this is probably the best greyscale testing video I have found

Try running fom SD card

I use Lighburn for my Jackpot V1. I only use the Wi-Fi for 3 minute or shorter burns, anything longer upload to SD card and run from pendent. I have ran 8 hour burns successfully many times 15,000KB files. The amount of code is to much for laser engrave on a picture changing power every 0.1mm on a grayscale image it overloads the buffer. your asking the Wi-Fi to send a lot of code for a very short distance

The DTR flag was the fix so I am working VIA usb cable

There is a recent driver update that a few staff members have found improved communication. If you loaded the driver before December it’s worth trying to download the newest one.

@vicious1 - we use that driver on Jackpot, so the notice about its update is one we should be mindful of.

@joe_s - what symptoms were you seeing with the older driver?

I’ve been decommissioning my windows boxes so would not have run into this.

Frequent disconnects was the main issue.

Thanks @Joe_S. That’s where I looked. I use a Mac and didn’t see an update for it so I wanted to ask to make sure it was a Windows only update.

Oh shoot, lemme swap the Docs link.

thanks for the heads up/
