Marlin RAMPS Issues #5426

Closed MH15 closed 7 years ago

MH15 commented 7 years ago

I've been building a custom 3d printer, and have some issues that I can't seem to solve. The Full Graphic Controller says the hotend temperature is always around 173 C, and the card always says either "card inserted" or "card removed".

Any help would be immensely appreciated.

Hi @MH15

Is that the temperature without heating? If so, what type of thermistor are you using and what does your configuration.h define for thermistor type?

define TEMP_SENSOR_0 1

define TEMP_SENSOR_1 0

define TEMP_SENSOR_2 0

define TEMP_SENSOR_3 0

define TEMP_SENSOR_BED 1

Do you have your board set correctly?

ifndef MOTHERBOARD

define MOTHERBOARD BOARD_RAMPS_14_EFB

endif

maybe you can include a copy of your configuration.h or copy it to dropbox and post a link back here. (don't just copy-paste it here since the markup screws it up)

Which version of Marlin is that? Seems very old. You need to uncomment

//#define SDSUPPORT // Enable SD Card Support in Hardware Console

macst34 commented 7 years ago

Hi @MH15,

Do you have another thermistor you can try?

Your config looks alright except for what @brainscan said about enabling the SDcard.

MH15 commented 7 years ago

@macst34, I did have some extra thermistors that I ordered so I took @brainscan's advice and got the new version of Marlin and everything worked with a new thermistor. Huh. But now, all 3 axes (in CoreXY) will only move in one direction, then start wailing.

Anybody ever experienced this before?

macst34 commented 7 years ago

Hi @MH15,

Are your endstops configured correctly?

it might be helpful to do a line by line compare of your old configuration.h and insert the appropriate values into the new configuration.h

Things like x,y,z,e steps need to make it over there. There's probably some feedrate and acceleration type stuff that would be helpful to get a starting point from. Since you have a corexy, you need to uncomment those defines in configuration.h. Use a program like "beyond compare" and figure out what settings need to be applied to the new version of marlin that you flashed.

Good luck,

Michael

You have INVERT_X_DIR to false and INVERT_Y_DIR to true, is that on purpose? That can cause you to lose your mind when trying to debug CoreXY movements. Usually you want both of these to be the same, it's hard enough to debug CoreXY without having an implicit flip of one axis over the other. :)
