Do you have a separate board that generates the laser diode drive? If so does it have two sets of inputs, one for power and another for control? Does it have a "weak" laser button?

T2 Engraving / Re: Home Switches
« on: April 16, 2019, 06:27:52 PM »
I had a similar problem with limit switches and a core-xy fixture. GRBL was setting the HOME position as the far right corner and any motion caused it to think the laser was past the physical frame limits. Problem did not arise until I did the homing operation and set the 0,0. My Cartesian fixture with homing switches works as expected.
There is a grbl command to show internal status plus some parameters to control which info gets displayed.

I would solder to the pins on the back side of the controller board and hot glue or tape the wires to the board. Might also add a 2-pin inline connector.

Perhaps useful for cutting trace on PCB's.

1. Disconnect the belts from the motors.
2. Disconnect the three motors from the controller
3. Connect each motor to the controller X port and test for motion.
4. Do the same for the Y port.
5. Swap all three wiring harnesses.
You can use a terminal emulator such as teraterm to issue simple g-code commands.
g0 x100 f600
g0 x0
should rotate the motor in both directions. There are software packages that provide primitive GRBL motion. perhaps Zax can provide the simple T2 method.
Put a piece of tape on the motor shafts to make it easier to tell if they are working.

For motor testing you could disconnect the belts and plug each motor into the port that is working. Also swap cables.
Possible problems:
1. Bad stepper motor driver.
2. Bad connector or wire.
3. Insufficient motor current.
4. Shorted coil in motor.

Trouble Shooting / Re: Replacing laser diode.
« on: April 10, 2019, 07:11:10 AM »
I have never replaced a diode but understand that it can be quite difficult as the diode is fitted to the aluminum heat sink with conductive grease which will harden over time. The heat also distorts the metal causing jams. You might want to also get a replacement heat sink and just add new wires from the electronics to the diode. Don't forget the thermal grease!!!

Is there a jumper under the Nano board?
The resistor is needed to keep the laser from going ON during CPU reset and startup for the 3-wire TTL configurations. Most 2-wire fixture behave ok.

OK. I was confused. Please post make and model or picture of board with the connectors.

Almost any of the newer controllers will work. You may need to manually cut/solder/crimp the 3-wire laser connector. I build my own boards so I do not have any part numbers. What frame are you planning on using? Perhaps you can get a controller with it.

That appears to be a 3-wire module, +12, GND & Signal. I don't see the connectors at the far end but expect 2 of them go to a power supply and the third is loose. When you wire it together make sure the the GNDs from the controller and power are connected.
Which controller board?

What are the wires labeled at the laser module?

At least the pictures of the blue anodized aluminum look good. I suspect it is intended to be used with the pointed engraving bits and speeds approaching 50mm/min.

1. You you have a 24V spindle motor in a 12V fixture?
2. I think 500mm/min is much to fast.
Please post some info/pictures of your fixture.
