I have i problem with extruder heater
April 03, 2017 08:58PM
Some times when i turn on the ormerod 2, i can get the extruder too print som PLA. and when i try tu print some thing it say that ther ist not any tool and i can`t print. A have never get this machin to print any thing. I have not upgraded the firmware on it. I read that DC42 have made many upgrades, but i have not tryed this. because i havent got the original setups to function.

Pleas help. Or pleas buy this machine from me :-)

The config fil is like this :

; Configuration file for RepRap Ormerod 2
; RepRapPro Ltd
; Copy this file to config.g if you have an Ormerod 2
; If you are updating a config.g that you already have you
; may wish to go through it and this file checking what you
; want to keep from your old file.

Try sending command T1 before you try to print.

I will try this, but know i got a new problem, When i took out the SD card for copying the Config fil in her. I now cant get the machine to work again. When i type M503, it come up the message "Can`t open 0:/sys/config.g to read from. error code :12 Configuration file not found.

Assuming that it is the same SD card that was working before, there are a few possibilities why that happened.

Your SD card might not be making proper contact - clean the contacts with a pencil eraser and try again - make sure that all the rubber bits are cleaned off and the card is properly inserted and locked in place.

The SD card might have become corrupt. Ensure you have all the folders and files it contains on your PC, put it in your PC, re-format it (FAT32) and copy the files back across.

The worst case situation is that some of the legs on the SD card connector on the Duet have become disconnected - you should be able to see if that is the case by looking at the solder joints carefully using a bright light & lens and try gently moving them with a small screwdriver to ensure they are properly soldered.

If you have changed to a different SD card, the most likely cause is that the card is a low speed grade and not being seen by the Duet. The fact that the Duet does not like low speed cards is really a firmware bug (not sure if that was ever fixed), but the solution is to use a higher spec card. If you cannot get the card to be recognized, it is worth trying a different card anyway in case the one you have is marginal. You can also upgrade to the latest firmware (it doesn't need to see the card to do that), though as said I don't know whether the SD card routines were ever fixed so that might not help.
