Extruder wont heat up, extruder stepper wont turn, and other

[TundraGeek]

Thank you you've been a huge help the last problem i seem to be having is the extruder stepper wont turn,i keep getting an error on Repetier Host saying its preventing cold extrusion whether its heated up or not

[Sherry]

please ensure the extruder is heated up,otherwise it won't turn.you could touch the extruder.in addition,did the Repetier Host show anything.did the lcd display infomation such as MAXTEMP ERROR .THX

no errors and according to repetier host the extruder and bed are fully heated, and because the stepper wont turn i cant get the filament into it. i need to go but i will continue working on it first thing in the morning

Hi,

You have to make sure that the board can read the temperature of the extruder if not, it will not work. After you see in the LCD that you can read the bed temperature and and the extruder temperature, try to move all the motors to the home position. if that works, then try to extrude few mm from the filament. if that doesn't work, in the LCD, go to Control, restore factory settings and try. If it works, then you have the old firware and you need to upgrade it to the latest one.

Good luck.

Hi.

The new software from the site had the same bug. I had to change it and remove the filament settings. Now it works without any problem. Im attaching the code im using now.

You can use the M302 command to test feed the extruder if you aren't running it through the hotend. This command bypasses the low temp limit and makes testing and calibrating your extruders a bit easier.

where do i put the marlin.zip?

Do you mean how to upload marlin firmware? you can refer to this:

[TundraGeek]

it wont let me drag the files into arduino, the mouse turns into a prohibited sign as i try and drag the files over

[Mark]

Then how about double click the marlin.ino file under the marlin directory?
