So, after is what is literally forever i'm so close and yet have no idea where to start. i'm trying to get my thermistor and heater to work on my reprap. I've got no heat and no temp readings. I'm assuming that the problem lies in the firmware but it makes no sense to me so I'm stuck. I might be having rs485 problems. haven't ruled it out. I can get the stepper motor to turn. I can't get temp readings or the nichrome to heat up. the temp readings i'm totally lost. the nichrome I know that I am not getting any voltage where the hook up is. The wiring diagram shows the nichrome heater hooked up to c-/c+ others in the forums have referred to hooking up the wires to b-/b+. I haven't found anywhere to tell reprap where I hooked them up. also the temp tables are just out of my league. I'm assuming that someone bought a thermistor like I did from ultimachine and made it work. Could you share your setup info? -aaron https://reprap.org/forum/read.php?13,53150,53150#msg-53150 Tue, 13 Oct 2026 00:13:44 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,53150,53328#msg-53328 https://reprap.org/forum/read.php?13,53150,53328#msg-53328
the led near the c-/c+ does not come on.


i've set the debuging and will post some info out of it. Anything in particular to look for?]]> lunchtrayrider Controllers Thu, 29 Jul 2010 10:41:04 -0400 https://reprap.org/forum/read.php?13,53150,53264#msg-53264 https://reprap.org/forum/read.php?13,53150,53264#msg-53264
Out of the box the folder contains configuration.h.dist ..you need to remove the .dist

hope this helps]]> CdnReprap Controllers Thu, 29 Jul 2010 01:39:31 -0400 https://reprap.org/forum/read.php?13,53150,53184#msg-53184 https://reprap.org/forum/read.php?13,53150,53184#msg-53184 Definitely sounds like an rs485 problem!

As floe suggests, turn on Debugging in the RepRap Host software by setting BOTH

• CommsDebug
• Debug

to true!]]> rhmorrison Controllers Wed, 28 Jul 2010 06:29:40 -0400 https://reprap.org/forum/read.php?13,53150,53181#msg-53181 https://reprap.org/forum/read.php?13,53150,53181#msg-53181
Can you maybe enable serial debugging in the reprap host software and share the console log?
