Welcome to the SeeMeCNC Community

Thanks everyone! The problem is now resolved. It was correctly identified earlier in the thread by Earthbound. (Reiterated by SeeMeCNC support. Thanks JJ!) The F2 fuse was actually blown. This is the first time I've worked with these fuses and I was just visually inspecting them, which was pretty ...

I think it makes sense to start at the basics. Do you have a multimeter of some kind? Verify voltage on each pair of terminals where 12v lands on the RAMBo. I pulled out my multimeter and checked the pairs. The 3 pairs are each reading 12.01v. (Just as a precation, I had some weird twisting when I ...

Looks like your stepper connections are reversed. Pin one ( little triangle on the connector) should be on the right of each socket on the Rambo. Page 194 on the manual is sorta confusing because the different types of steppers the kit can ship with. Although I would of expected them to still work ...

Here are few pictures of the rambo, if you need any more or of anything specific, let me know and I'll take more.

Thanks.

The F2 fuse looks ok. https://i.imgur.com/2OpBq4H.jpg

(I recently swapped the fuse to make sure.)

It doesn't physically do anything when I click to raise or lower. (I see the commands being sent, and printer responds with "ok 0")

They are free.

Hi Dale, I reran the end stop test and they seem to be functioning correctly... Without any end stops pressed. ->M119 <-ok 0 <- <-x_max:L y_max:L z_max:L X pressed ->M119 <-ok 0 <- <-x_max:H y_max:L z_max:L Y pressed. ->M119 <-ok 0 <- <-x_max:L y_max:H z_max:L Z pressed <-ok 0 <- <-x_max:L y_max:L z ...

I finished assembling a Rostock Max v2 and ran into an issue before I started the calibration section of the assembly guide. I'm unable to home the towers. I've tried to "home towers" from the LCD, which just causes the LCD to freeze for about 20-30 seconds, then beeps. The LCD has a message at the ...
