I’m an alumni of FRC 3574, and we have a Delta-style 3d printer, powered by a Smoothieboard, that went out of commission some time ago due to a broken thermister. I’ve replaced the old head entirely, with an e3D v6 extruder head, and wired it all in. I can confirm that it heats up as it should, and measures its own temperatures fine, but now the issue is that the head is a few millimeters longer than the old one, so I need to reset the distance from the head while homed to the bed to be shorter. If I try to jog it down to where i need it to be, and use the “Set Z0” option in the menu, it doesn’t appear to do anything. I also cannot run a G32 without the head pressing onto the glass bed and causing the timing belt to jump, because it just won’t stop.
This head doesn’t have a probe on it, but but the bed rests on three pressure sensors, placed on the center of each of the three bars that form the base of the printer. I feel like part of the issue may be that they’re not plugged in properly, but as this printer was gifted to us, and I can’t find any instructions or documentation on these, I can’t say for sure, and the board they plug into is not the smoothieboard, but some other device that I can’t find a name on.
Basically, I just need to figure out how to tell the printer where the bed is now, with a longer head on it. Below is my config script, so hopefully that will help. I have pictures as well but I’m not sure of how to add them into this post.
