If I enter the codes G28 X and G28 Y then tell it to print without a G28 code in the gcode file it works. If I have the codes G28 X and G28 Y in the gcode file with no G28 it works. If I just have G28 it stops working. Must be something with the Homeall file. There are no comments at the end anymore. The F360 parameters are there. Wow am I baffled!!!

So when I say Homeall manually it is pressing the home icon on the PanelDue screen. Sending the G28 command from the gcode file not manually from the screen. I will try if sending the code individually if it works and I will then test to see if removing comments makes it work as well. I will do them separately so that I know which one is doing what.

OK, well it works now if I do the Homeall manually. If I issue a G28 ; home all axes then the system will home correctly but then just hangs up. No messages in the console nothing. It just sits there and I have to reset and manually do the Homeall then run without the G28. Ideas?

I am confused as well. It looked to me like things were correct. Now with you being puzzled now I am VERY confused. I will try those suggestions to see what happens. Thanks for the help!

If I home either only X or only Y I can move those axis just fine. It I home both then it locks up. Here are the Homing files:

I am homing at the front left of the printer. The XY position displayed is 0,0. The endpoints trigger (and the board LED lights up) when I press the contacts. The X axis increases when I go to the right. The Y axis increases when I go to the back. Here is the config.g

So I had the same type of issues in the previous posts but now it will home the X and Y axis correctly, The drives go in the right direction…Awesome...but...now when I home everything seems to be locked up when I try to make the X or Y axis to move. I can't move by g-code or by pushing the buttons on the PanelDue or Web page. Any ideas?

I tried the sample g-code:
G91 ; relative mode
G1 S2 X10 ; move the X motor forward 10mm
G1 S2 X-10 ; move the X motor back 10mm
G1 S2 Y10 ; move the Y motor forward 10mm
G1 S2 Y-10 ; move the Y motor back 10mm
G90 ; back to absolute mode

Works UNLESS I home the X axis and Y axis then nothing. It just stops and no further movements work.

If I connect 2-12v DC terminals from the same power supply I should have only 12v DC correct? If I put them in parallel then I would have 24v DC and that should work for 24v correct?

So I am new to using the DuetWiFi and I have a 300mmx300mm dimension system. I will be using a 120v heated bed. I have a lot of 12v Corsair RM650 12v power supplies. Would you recommend hooking those up to the Duet or should I get a 24v system to start out and make sure I get a 24v hotend etc. or do you recommend something else. I just want to do the best to begin with so I don't have to do it again. Thanks!
