Send g-code directly to reprap Hi All, I just recently acquired the parts and assembled 98% (theres a few loose ends to tie up) of a mendel reprap that will uses gen 3 electronics and makerbot mk5 plastruder components with a bowden type feed system. I fired it up and drove the axes around using replicatorG just this evening. I would also would like to write up some code to drive the reprap for some specialized applications that I have in mind for down the road, but sending g-codes through the serial connection manually doesn't seem to work. I've tried using the arduino software console (with and without CR appended at the end) and also tried it using Matlab to send the serial g-codes to the motherboard. In both cases, the motherboard debug light switches from the slow steady blink to 4 blinks with a pause in-between. So, does anybody have an idea of what the correct way to format and send the g-code manually is, or what I'm missing? Also does anybody have a table of what the different debug light blink codes mean? https://reprap.org/forum/read.php?4,64582,64582#msg-64582 Tue, 21 Jul 2026 12:22:34 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,64582,64604#msg-64604 Re: Send g-code directly to reprap https://reprap.org/forum/read.php?4,64582,64604#msg-64604
I'll give the send-gcode.exe a try (not sure why that thread didn't come up in my search).

Also, you're right. I guess I don't need to reinvent the wheel. If I just generate a custom g-code file and send it through a host software it's the same result. Thanks for your thoughts!]]> liger_tamer Reprappers Sat, 23 Oct 2010 11:28:27 -0400 https://reprap.org/forum/read.php?4,64582,64594#msg-64594 Re: Send g-code directly to reprap https://reprap.org/forum/read.php?4,64582,64594#msg-64594 Or send-gcode.exe here: [forums.reprap.org]
Of course you could also open any gcode file in your RepRap host software of choice and send it to the printer. Not command line though.]]> Nudel Reprappers Sat, 23 Oct 2010 07:45:19 -0400 https://reprap.org/forum/read.php?4,64582,64584#msg-64584 Re: Send g-code directly to reprap https://reprap.org/forum/read.php?4,64582,64584#msg-64584
I successfully use 
stty raw ignbrk BAUDRATE < /dev/ttyUSB0
( cat <&3 & cat >&3; kill %%) 3<>/dev/ttyUSB0
for debugging]]> Triffid_Hunter Reprappers Sat, 23 Oct 2010 00:27:34 -0400 https://reprap.org/forum/read.php?4,64582,64582#msg-64582 Send g-code directly to reprap https://reprap.org/forum/read.php?4,64582,64582#msg-64582
