I can only assume that you have never used IRC before...? If not then you will need to get an IRC client. There is mIRC on windows, but also Pidgin supports IRC. You will have to use google and the internet as a resource to figure out how to setup your IRC client because it would take me too long to explain here. Once you are familiar with your IRC client, just connect it to the irc.freenode.net server, and then join the #repsnapper channel. You will then be able to have a live chat with the developers of repsnapper if they are around, also there is of course the #reprap channel to try. Good luck

Giles
Thanks for your help
I’m still at yahoo groups, I didn’t figure out how to get into the irc repsnapper channel. Could you spell it out for me! We flipped the motherboard ( same march copy of 5d) the laptop and the stl file. It still comes up with random moves that aren’t in the g code. It has happened on the X,Y and E axis so something has to be telling it to go there.
Thanks again
Jeff

Well repsnapper and the Java host software send checksums with each line of GCode. When communication errors occour, the firmware on the motherboard will detect that the checksum doesn’t match the corresponding line of GCode and request that the GCode be resent. So I have no idea what could be causing your problem, but I don’t think it can be related to communication errors. Probably the best place to ask these types of questions is in the #repsnapper irc channel on irc.freenode.net

I am getting random communications errors that send the machine to destinations unknown. If you let it run until it gets there it will come back and start printing again. It is not in the Gcode and we swapped out the main board. I am running the march release of 5D firmware and Repsnapper from the link listed above. Any ideas?

I don’t think there is any extruder reversing feature in repsnapper currently although I have heard that its a planned feature. There is however already the ability to edit “Start” “Next layer” and “End” GCode sections within the GUI, so if thats not available for you maybe you have an older version of the software.

Thanks for the help
Is there a method to make the extruder back up a few counts at the end of a line to stop nozzle drool and stringy parts?

I there a tool to edit the Gcode start middle and end scripts or do you just have to modify the xml file like I have been doing?

When repsnapper sends the next command, if it doesn’t receive an “ok” then it just waits forever. Kicking it gets it moving again

Can either of you guys tell me what the kick button is supposed to do?

Nice work!!
