@DDUJ It could be a firmware issue but more likely the MOSFET has failed, you would require a volt meter to check the controller outputs. If the D11 output on the Nano is working and the MOSFET is not switching then you need to replace the MOSFET or get a new controller.

@AlanKWatson68 If you are using Grbl 1.1e DEFAULT it does not need to be changed. The laser is controlled by D11 (PWM) from the Nano, you can use a volt meter to check the output signal (TTL) to make sure it is wired correctly.

The CH340 driver is just for the COM port, if you can connect then it's working fine.

Check the cartridge
Many users reported that this issue appears because of a cartridge malfunction. Also, the printer might be out of ink. Usually, the device shows a notification if these situations occur.

To solve the problem, you should install a new color cartridge. If the problem persists, see the next solutions.

Set up your device to print color
If you installed the driver correctly, you need to confirm that your printer can produce color documents.

Click on the Print button.
print button
Check if the printing option is set to Color.
select color print

Use the correct driver
If your printer doesn’t print in color, make sure you installed the correct driver for your device.

Search on the internet by typing the name of your printer along with the word “driver”. See if the result matches the driver from your computer.
Alternatively, go to the manufacturer’s support page to find out the driver for your printer.

Check the printheads
Sometimes, the printheads are clogged with old ink, so your printer can’t print color
If that’s the case, you should clean these components.

Find out what is the problem: To fix the payment failed to issue you must first understand the problem and check your amount and then check your bank account and check whether the money has been deducted and then the transaction Check status (pending or failed). This is very important to locate the node if there is a problem. Cancel the payment: After making a transaction on Cash App, if your bank account shows the payment but it is not visible in your Cash App account then you should cancel the payment immediately. In this case, the money is on your safe side because the payment has not been transferred. Within 24 hours of sending money to cancel the payment to avoid deducting money from the bank account. You need to cancel the payment within 24 hours of sending that your fund will not be deducted from a bank account. Cards Declined: When you make a payment on Cash App and then these messages pop up:
· “Declined. Use another card.”
· “This card has expired. Use a different card”.
After payment failed on Cash App if these messages show on Cash App screen then you must check if your card is valid or not. You should check whether the card details that you have entered the correct or not. Please re-check the card number, expiration date, CVV, and ZIP code.”

@paul-nelson-baker They do sell set screws at home depot also, usually in the small drawers but glad you found something that will work.

Thnks!

For my 3018 the $3=4 returned OK and Z axis god inverted.

@yippiez It could be the software or firmware, the easiest test is to use a terminal program to connect to the machine and see if it responds correctly to the probe.

You could use Grbl Controller or better still something like CoolTerm to connect with the machine.

If you send: G38.2 Z-10 F20

It will cause the probe to move down 10 mm at 20 mm/min, and when it makes contact you will get a response such as:

[PRB:0.000,0.000,-0.525]

Which means it found the probe at -0.525 mm.

The software would then set the correct Z value based on the thickness of the probe.

awesome
