Rev F6 Board and motor grinding

Postby Meph » 2016-Nov-Thu-11-Nov

My microusb connector broke off my Simple Metal. The pads had lifted a little and I had no luck fixing it so I just bought a new one. THe new board is a Rev F6 with the full size USB connector. I installed it this morning and now I am having issues. You can see in the video below that during the bed leveling when it moves to the front left corner of the bed it moves all the way to the front and grinds as it pushes too far forward. Then the Zaxis shakes as it lifts the extruder. Then it moves forward fine a couple steps and lowers. The rest of the bed leveling goes fine.

I setup a test print with it centered on the bed. Instead if moved all the way forward, grinding as it tried and then began printing right on the front edge of the bed. I am printing with Simplify3D. I tried to go back to Cura and try that but now with the new USB, Cura won't recognize the printer on my desktop or my laptop. Any suggestions where I should start?

Where did you get the board? If you got it from Printrbot, they should have configured it correctly for your printer.

The bed dimensions are probably available to you in EEPROM and can be changed. For setting your bed size and probing locations there are several threads in this forum. For one example of many, see viewtopic.php?f=15&t=11191#p71893

As to loss of communication, it's possible that your new board maps to a different COM port address than the old one. You can easily find out the correct address in Device Manager, and then set Cura or Repetier to use that address.

Thank you RetireeJay. I just assumed it was configured correctly. When you mentioned that I decided to look for myself. That board had M212 X/Y/Z all set to 250. Set them all to 150 and we are back in business. Not to test some prints and see where we are at.
