FuseBox ~$300 CoreXY Printer

Ok, I swapped the cables on the back of the graphics display and that worked, so the display now works. Applied the correct thermistors, and now the display says bed thermistor is defective, and still says the hotend is heated even though it's off. Motors still don't move.

Here is the RH log from start up, in case this helps:

Bump.

Still having this issue. I tried a different thermistor in place of the bed one, because the graphics controller says its defective, but it says that with the new one too. I'm using firmware I downloaded from the Thingiverse page, modified with the link from a few posts ago to add a heated bed, full graphics controller, and an e3d volcano.

Could the pins for the thermistors be incorrect? I plugged them in like I would on my other 3d printer, bed in 0 and hotend in 1. Now I think I should swap them and see if that works. Anyone who has set this up before on a RAMPS 1.4 let me know how they wired it up, or maybe if I need to find where the pin assignments are and how to change them? Thanks!

You're using RAMPS 1.4? Make sure you have the jumpers for microstepping installed under the stepper drivers.

Also make sure you have your motors wired up correctly. Check here
Basically the 2 wires for one coil should be next to each other in your connector as well as the 2 wires for the other coil should be next to each other.

For the endstops, at the RAMPS end put them on the X,Y,Z-min pins here

You should have 2 wires in the connector
One should be in the middle which is the -
The other should be in the top which is the S

At the switch end, one wire should go to the Common, usually labeled C on the switch
The other wire should go to the Not Connected, usually labeled NC on the switch

Also you do need to configure it in your firmware, right now you have it set as if no endstops were connected.
You should set your X,Y,Z-min to "Switch on GND, normally closed"

Lastly you can send M119 through your host to get the status
I'd say make sure none of the switches are being physically triggered then issue M119
They should all report open. If not you've got a wiring issue

Send M503 to see if it's actually using the steps per mm you're telling it.

It's possible that even though you've flashed 1600, that it's still using 400 from EEPROM.

If it's still using 400, send:
M502 to load hardcoded defaults (the ones in your configuration file)
M500 to save those settings to EEPROM

Then do M503 again
