Well aren't you absolutely right! I did check the PSU voltages, but totally missed the part where he said to check the jumper block.

Strange indeed - I can only assume it was making enough contact to power the logic of the board, but not enough for the stepper motors.

So - i figured it out ... THIS was weird! I was looking at this picture below to try and figure out if I could somehow test the voltage going out of the RAMBO into the stepper motors... and I noticed over on the right - the - and + for "Motors and Logic" - so I swing the multimeter over there to see ...

Yup - already have a case open with them.

I would have to check - but it is whatever it came with 8 months ago..... and it has been working perfectly fine the entire time - with no change to the firmware... Do the stepper drivers go out? I see on the rambo mini they talk about a better design with heatsinks to "never have a stepper driver ...

I usually use octopi - I completely blew it away, and also just tried to home the device (or calibrate it) from the front panel.

All seems good - I have a note out to matterhackers.com to see if they do any service/support.

Fuses did check out - but I replaced them anyways - still no stepper motor action. Anything else I can check? I doublechecked all the wire harnesses - everything is in tight (and remember, it was just sitting there for about 3 weeks doing nothing when it decided not to work)... everything else seems ...

Thanks - I see in a picture two small ceramic 5a fuses... I will take the out tonite and test them and let you know! I know the larger car type 15a fuse is good.

Hi Folks - I fired up my Rostock MaxV3 last night to print some stuff after it being off for about a month.... loaded the G-code file, went to print it... The bed heated up, and then the extruder - and then.... nothing..... when I went to the console (I use octopi) it looked like it was sending the ...
