Hello, Lighturn community. I’m working on upgrading a shapoko 2 with a J-tech laser. The firmware was 0.9 I did the upgrade to 1.1f, the laser is mounted and soldered in. I have a couple of issues that I can’t seem to figure out. Starting lightburn the machine connects I can more the machine but I get an error 9 and can not set a home position for the machine. Also, none of the limit switches seem to engage if pressed. The machine just wants to keep going even when at the end of the tracks. I’m not too familiar with the wiring for these machines. From what I read these issues could be a wiring problem or a configuration problem. I did all the configuration as instructed from this link, https://jtechphotonics.com/?page_id=1100 This is the link I’ve been using for the upgrade and have followed everything they suggested in there. I can’t seem to figure out why the error 9 is coming up and why none of the limit switches are engaging when pressed down. Has anyone done this upgrade that could help with figuring out how to fix these problems? I attached 4 pictures of the wiring maybe something is missing? Thank you in advance for your time and effort.
You don’t have homing ($22) or hard limits ($21) enabled. Your switches won’t do anything.
Error 5 is most likely because you tried to home the machine with homing disabled.
I’ve enable them by switching it from 0 to 1 and it’s still giving me the same problem. The switch are pressed but the machine still wants to keep going. The still don’t engage.
I apologize for the late reply I’m only around the machine on Saturday. Out of town during the week. When I hit home it dose nothing I get this message after it loads.
Your controller is most likely in a metal enclosure at a corner of the machine.
It looks like reflashing went well — have you tried using it per: http://shapeoko.github.io/Docs/software.html (though that will need to be adjusted for Grbl 1.1 and the specific software you are using — concepts should still apply).
Thank you for the quick reply. The software I’m using is lightburn. And I’ve setup the confirmations specified for this laser upgrade. And still the limit switch will not engage. I’m thinking there may be a wiring issue.
I’ll check that out. If I have the limit switches enabled would you have an idea why they are not engaging when pressed? I’ve searched and tried everything I could find and nothing seems to be working. I just keep getting error 9 I lightburn and the machine just wasn’t to keep moving even when the limit switches are pressed down. I am at a stand still with this because I have no idea when the problem could be.
@josephkerr, I’m not familiar with the wiring of limit switches on the Shapeoko2 and this controller, but I can’t picture where the wires for each limit switch go on the controller ?
Do you have happen to have Carbide Motion installed ? If you do, there is a handy feature in the Settings page that will print out a message when any switch is pressed. That would be a good way to check whether the controller actually sees the switches being triggered when pressed.
