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. 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.
I believe it’s a gShield on top of the Arduino. And that what the machine came with was GRBL 0.9. The link I used for the upgrade said to use GRBL 1.1f. Is TinyG/G2 firmware better for the Jtech laser?
error:9 : _(“G-code locked out during alarm or jog state”),
The first, “Msg: check limits” may indicate that a limit switch is pressed already, and therefore the transition can’t be read. That said, I know very little about the Shapoko machines or how they’re supposed to be configured. The homing cycle is enabled, as is the laser mode. After you’ve connected, are you able to click the home button? (does that work?)
Limit switches won’t do anything unless the controller is set to use them. Yours is not set to do this - $21=1 would enable the hard limits (the switches) and $20=0 would enable soft limits (the controller will try not to run into the limits by enforcing travel distances).
The home button doesn’t work. I apologize for the mistype.
Home button dose not work, if I hit home it loads and says busy, but nothing happens.
I’ve let it sit for 10 minute and nothing happens. I end restarting lightburn and starting the machine up again to get it to do anything.
I’ve enabled both the hard and soft limit switches in light burn and still get the same results. I’m really starting to think it’s a wiring issue. Because no matter what configurations I use the limit switches will not engage when pressed. The machine just wants to keep moving.
And once I get back to the machine I’ll try what is in the link you posted. Thank you for the advice and taking the time to send that.
Shapeoko head is really heavy for scanning passes, probably not the best base for mounting on a laser. (especially without shielding of any kind from the beam, extraction, etc).
