New HE280, extruder stepper won't go, calibration script does nothing

I could use some help. I've assembled and installed the new HE280 on my V2 and I can heat the nozzle and bed, home towers, and move on all axes in MatterControl's controls correctly, but I cannot control the stepper motor, and if I run the "V3probing" G Code, the machine does nothing at all. I flashed EEPROM and isntalled new firmware, setting the board to 301 and the machine type to 2 (V2).

Stepper: I have confirmed continuity from the connector that plugs into the RAMBo to the last splice before the stepper, and 12.75V to each pin in the E0 connector on the board. It is possible that I unplugged E0 from the board while it was on at some point. geneb says here http://forum.seemecnc.com/viewtopic.php ... 844#p96029 that this will kill the driver for that channel and later that it's possible to tweak the firmware to use E1 instead. Does anyone know anything more about either the frying of the driver or altering the code to use E1?

Script doesn't work: "Printing" the script doesn't make anything happen. It sits there and then homes when I cancel it a while later. MatterControl seems to think it would take like 20 minutes to complete. Here is the G Code it spits back when it first runs:

I suspect that you'll have to set the board type to v3 due to the use of the accelerometer(sp) board. You may also have to invert the Y(?) axis if you've got a v2 as I think all three motors in the v3 are oriented the same.

If the hot end isn't hot, it won't extrude. Also, manually extruding from MC has been problematic forever.

Well there you go!

I have apparently never tried to run the extruder while the hot end was cold. Makes sense.

I actually started out indicating the machine as a V3 in the firmware, but it gave me the crazy arms with the inverted Y axis. I hadn't seen anyone mentioning that, so I just figured, "That can't be right." and switched back.

And then with the V3probing, I somehow got it off of github with all kinds of extra html tacked on. I don't know what's up with that, but the correct file seems to work as intended!

Thanks!

For anyone's future quick reference, here is where the Y axis needs to be inverted in the firmware:

Code: Select all

// ######   Inverting Axis Settings
#if PRINTER == 1 || PRINTER == 2 || PRINTER ==4
#define INVERT_X_DIR 1
#define INVERT_Y_DIR 0
#define INVERT_Z_DIR 1
#elif PRINTER == 3
#define INVERT_X_DIR 0
#define INVERT_Y_DIR 0
#define INVERT_Z_DIR 0
#elif PRINTER == 5
#define INVERT_X_DIR 1
#define INVERT_Y_DIR 0    //inverted from defualt 1. V3's motors all face the same way, V2 does not.
#define INVERT_Z_DIR 1
#endif

I have been struggling with getting my printer back operational after upgrading to the HE280. After following the instructions included here, I was able to get it back functional again. Currently waiting on a test print now, but everything is looking good.

However, after the upgrade, my LCD no longer functions. I can hear sounds as I move the control and other such things, so I assume everything is working in there, except for the LCD itself. I will get in touch with support and see if they have recommendations, or maybe it went bad.

My printer cracked off a cheapskate while printing a larger model. Suggestions are that my printer needs to be kept warm, which makes sense because I am normally overheating, so have fans running. I have an idea to use a hula-hoop and something like a shower curtain. I will probably use lights to provide the heat. Relatively cheap and very easy to construct.

@Gene, your documentation and assistance in the forums has been absolutely invaluable. Thank you very much.

@Humanzee, I appreciate you posting this, as I was going through exactly the same issues.
