Thank you Dust, it was the speed, @115.2kbd the communication is up. So back to my firmware issue: It turns out I have some pretty old stuff in here, to M115 i got: FIRMWARE_NAME: Sprinter FIRMWARE_URL:http%%3A/github.com/kliment/Sprinter/ PROTOCOL_VERSION:1.0 MACHINE_TYPE:Mendel EXTRUDER_COUNT:1 UUID:00000000-0000-0000-0000-000000000000 ok And I could not get anything out from the setup...

Hm... I cannot get CoolTerm to communicate to my controller. When it connects, it echoes two extended ascii characters, but after that all command is taken and I see no response, like firmware info after M115... I am not configuring CoolTerm properly, or something else...? Please let me know if anyone has some pointers for me... Thanksby kosatomi - Reprappers
Thanks FA-MAS for the extra info, So I went to research the topic and decided to send M115 (firmware info) to Marlin, that surely must be implemented even in my older version... I tried three different serial terminal to talk to my Arduino Mega: a) Arduino IDE: when I open 'serial monitor' I get two squares but after that nothing, no response for anything. b) tried CoolTerm but I am not sureby kosatomi - Reprappers
Thanks for the further explanation. So the pulley on the X&Y motors are 8 tooth, not 9... I checked again the z leadsrew pitch, came to ~1.22, if 1.27mm is a standard then that must be it. If I understand correctly: I cannot just change the steps/mm for the 3axis and extruder on the fly; I need to set them in Configuration.h, compile the Arduino project and upload as a new firmware. To getby kosatomi - Reprappers
Hi SupraGuy, thanks for your reply. I completely understand what you are saying. Yes, I do not have the original Configuration.h, so I do not know all those conversion factors... I assume I cannot quiz it from the controller, like one can do it with TinyG? Here I add a bunch of pictures about the printer; looks like that in the past we might have modified bits and pieces on this machine since itby kosatomi - Reprappers
Dear All, We have an old ultimachine.com RAMPS V1.3 3D printer collecting dust; I'd like to bring it back to life. Put a new Win7 x64 box to it with latest Arduino IDE, Repetier Host. Printer has some upgrades: proper, flexible Al coupler on the Z axis motors and a more sophisticated looking extruder. As it is, I printed Benchy and the main issue was that he Z dimension came out ~30% shorter. Iby kosatomi - Reprappers
