Hi,

I have a GTM32 Rev B that has failed.

I have checked the fuses and they are good.

Can you provide the schematics for this board ?

Could you provide more details about your board problems?

Hi William,

After more examination it appears there is a problem in the 3.3v supply or possibly before it.

I am hoping to get the schematics to troubleshoot the problem further.

Hi William,

What is so secretive about the GTM32 Rev B. ?

You have released the schematics for the GTM32 Pro B and the GT2560.

Why is it so hard to release the schematics for the GTM32 Rev B ?

I also have the same desire for a schematic but respect the wish for keeping the schematic private. ;)
But could you at least give me the specification for components QB1 (placed next to the buzzer)?
I do not measure the correct diode drop (or what I think should be the correct values). :geek:

I've been having issues with getting my rostock 301 with the gtm32 pro board to work. I'm new to 3d printing but I know some things about computers so thought I could get this machine up an running. I've been having trouble with getting instructions on how to get the bootloader to flash on the board, what I should be using the st-link for (I can't get it to link to the board), the jumper instructions for this board, the gtm32 pro, and how to get it to work, when I click home it just crashes into the printer bed, and does this jackhammer thing. So finally I saw the hotend twitch and the screen went blank on my printer and now the board isn't connecting with the hyperterminal, it just says Jump app failed! From what I'm reading I need a new board now. I've never seen this printer running and really want to see it up an running, it's only 7 months old, I bought it from one of my teachers at school who couldn't get it working. How do I get a replacement board, and how long does it take to get, please advise, thanks.
