I have been sent a Melzi 4 board, but I do not seem to be able to get Pronterface to talk to it, to change the settings - Has anybody had this board or any experience with it to allow it to talk - Your thoughts would be useful ?

Thanks,
The Device Manger is saying "USB Serial port ( com 3)"
Ponterface is saying it is trying to connect to Port 3
I have tried deleting the port, but when the plug reconnects it is still showing on the Devide Manager Port 3
The link cable should be OK as it works with the other computer (win 7)
AS further suggestions please?

Printrun/Pronterface
What did you find to solve the problem - I have the same issue that the port on 1 computer (Tosbiba portable Win10) has stopped opening the port connection (after a year without problem upgraded from Win 7 Professional) , but with another computer (Toshiba win7 ) works ok - so I know it is port connection on the Win 10 computer is the issue -

I have success by using a soldering iron to melt the two pieces together. The soldering iron can help to stick down any corners that are lifting on the print bed.

Many thanks Norman, and I have been busy trying to perfect a single head, (and gotthingsgoing pretty well. I am just about to go back to trying to get the tri colour working.
I can download the raw code, but is there a simple way to download the .stl files. (as I am not sure what to do with the code!!)

Thanks guys,,
I think the easiest test is the boiling water, the PLA goes soft and the ABS remains hard, Its simple.

Is there way to tell the difference between ABS and PLA?
I have received some filament,without an indication as what it is and I am trying to decide if it is PLA or ABS

Hi All
I am trying to download files from Github despository, specifically for;
Download the colour test object simple-test.rfo (download the individual white, red and green stls for Slic3r) from our Github repository here. Don't worry if your test colour filaments are not white, red and green as in the picture above. I am logged on to :
I do not appear to be able to copy the file to download.

Appdev007- Thanks for that.
For others information, I did not have the hot end connected as I wanted to extrude the filament into open air to see what distance was being sent and compare, the designated computer control distance with actual. When after 3 extrudes (or 3 reverses or any combination) does not do anything more, then the components/ingredients get questioned.
Experience!

Being new to this game. and having expermiented and taken the extruder to pieces, replaced the servo, re-downloaded pronterface, used another computer, plus another copy of ponterface, I think that what I was trying to do was to extrude more than 3 times in a cold condition , which I would suspect, the software does not allow.
I reassembled all the bits together again and had a good print, so

Quite a lot of the extrusions require straight sides. Has anybody tried to make a square hot end hole, and if so, has it provided any better results?

i have put one of the output legs on an osciliscope and there is no steps being transmitted after the 3 operations of either exrude or reverse.

I forgot to add that I have tried another servo, and this performs exactly the same.

I have a RipRapPro tricolour machine and just commissioning it with the kits own controller. (So learning about it!)
All servos perform as expected using the Pronterface Programme save for the extruder servo (which upon some investigation) will only work for 3 operations, either extrude or reverse before stopping and locking on. This servo will only work again if the controller is switched off
