Mini Gerbil Installed, Moved once and Never Moved Again
Quote from Christopher Brace on August 27, 2021, 2:53 amI have send a support email out but now I'm registered on here hopefully someone can help me.
I installed the Mini Gerbil in my K40 replacing my m2 nano yesterday. The actual installation was easy, I have a type 2 PSU so installed the cable to that fine, and only issue was I found the limit switch plug (non ribbon) was reversed so that went in turned around to make sure x and y were mapped right.
The first time I turned it on all seemed fine, plugged it into my pc, found it right away, lightburn auto detected it and configured it fine. The first thing I did was hit the home button and it moved in both x and y towards the home switches but it bounced on the y switch and stopped never reaching the X. This was wrong so I turned off the machine to read over the forum and install info again.
After some research, I found a few possible fixes on the forum so I turned it back on and it tried to home automatically but the motors didn't move and the console pops up with :-
Waiting for connection...

I haven't had the machine move with the mini gerbil since and I hadn't touched the hardware since turning it off after the bad homing. Since then I have:
- Disconnected the board and plugged the m2nano back in and it moves and homes just fine
- Checked the plugs are seated and correct onto the board
- Typed $X and tried moving the laser using the arrow buttons on the move screen, it didn't move but from the console info it seems to think it is moving.
- Replaced the mini USB cable in case there was a data issue, same result
- Tried a different PC from another machine and got the same lack of result
- Tried using Laserweb, again with the same output as above (Alarm 9)
- Switched over to USB powered briefly and got the same result (suggested on the forum)
- Turned off Auto homing in the device setup to see if it would move if it wasn't asked to home when booting, Still no movement
Basically, as far as I can tell the board isn't sending move commands out to the motors, which seems strange given the first time I turned it on it did move.
I'm attaching pictures in the hope they may help. Thank you in advance for your assistance!

I bought some new stepsticks because that's the only thing the troubleshooting says and no reply yet.
I set them to the setting shown on the stepstick adjustment section and put them in the machine and the X axis now begins buzzing when I try to home the machine. Y still doesn't seem to be doing anything.
I tried adjusting them up for more power but I don't know what I'm doing so I've stopped at about 90 degrees up from their base setting and still only buzzing, no movement, how far should I be turning these? I'd really appreciate some help here.
UPDATE 2
I have finally managed to get it moving!
I installed the new stepsticks again, rather than putting them to the default shown in one of the blogs I decided to start lower and work my way up and to my surprise when I turned it on, the Y moved. Turned it back off and adjusted the x counterclockwise to be even lower and tried again and they both moved and homed. I'f I'm correct from the information I have here I reduced the pot when I turned them counterclockwise, I don't know enough about them or the motors to know why it worked but it did.
They were a little herky jerky so I spend a little time adjusting the pots a fraction at a time and now I have the machine moving and cutting. There is a still a little very slight jerkyness you can see if doing a fine engrave but I'm going to clean my rails before I blame that on the board with it being so tiny.
I do seem to have a problem with the signal getting interrupted when doing a longer engrave so I will have to look at whats causing that but with now I can at least do the basic work. If any can help on the interruption issue or link me to solution id be thankful but its not a grounding issue, or USB length issue and the USB is away from the PSU and power cables so its non of those.

Google how to prevent this. All laptops seem to be set this way by default to save battery power.
