Since I pressed the erase button, does that mean that I erased everything on the SD card also? If so, how do I open and view the files on the SD card to make sure that they are there?
-
Pressing the Erase button does not erase the SD card.
You can take the SD card out of the Duet and use a USB adapter to put it in a PC to check the files.

I keep getting the message from my printer saying this whenever i try and send a Gcode :
G28
SENDING:G28
Attempt to move the head of a delta printer before homing the towersor… when I hit the interface buttons in pronterface

-
what's in your homeall.g or homedelta.g?
-
I'm still getting those same messages above from the printer whenever i tell it a command. everything on the SD is right and in place because i had it moving before I accidentally hit erase.
Would anyone know what exactly is causing the printer to send those errors or what the errors mean?
Any help would be appreciated!

This message:
G28
SENDING:G28
Attempt to move the head of a delta printer before homing the towerssuggests that either something is seriously wrong with your homedelta.g file, or that the motors are not responding to movement commands - perhaps because the motor currents are not set. Try sending these commands:
G91
G1 S2 X10and see whether it causes the X carriage to move up 10mm. If the X carriage doesn't move, run M906 to see what motor currents are set.
-
I tried G91 and G1 S2 X10 but no response from either,
M906 gave me this:

Are you sure that your Duet is receiving 12V or 24V power - is the blue LED lit?
-
Yes, I have it plugged into a regular wall outlet and the blue led is lit on the board.

Please post the contents of your config.g and homedelta.g files.

I didn't spot any obvious problems with those files. So something is stopping the motors moving. Please run M122 and see what supply voltage it reports, If the supply voltage doesn't reach 10.0V initially, or subsequently falls below 9.5V, then the motors won't run.

This is wrong:
Supply voltage: min 0.0, current 1.1, max 1.1, under voltage events: 0, over voltage events: 0
It should be around 12V or whatever your VIN voltage is.
Please check with a multimeter that you really are getting 12V or 24v (depending on your power supply at the VIN terminal block.
-
I tested my power cord that plugged into a regular wall socket at 110V and the multimeter read 113V. I then plugged the cord into the power supply for the printer and tested the wires that hook up to the board and they read about 21V.
Does that seem like a normal reading?
-
Was that 21V reading with the board connected to the power supply?
What power supply are you using?
-
No that reading was from the leads from the power supply which was plugged into a wall socket.
I am using the power supply that came with the D300VS printer. The number on it is DA16082403420. It has a built in fan that automatically turns on and off and has the option of changing the input voltage that it receives from the outlet (115/230V)Also if this helps at all, when the power supply is hooked up to the board and I turn it on the printers LED lights do come on along with the hot end fan,
-
Does anybody have any suggestions?
-
When you mean M122 and got the voltage reading of 1.1V in the report, did you definitely have VIN power applied, and was the blue LED definitely lit? Please run that test again to make sure.
-
What do you mean by VIN power?
