RAMBo flashing error

Software / Firmware
1

so, as I figured, software/firmware is not going as easily as I hoped. I have installed the RAMBO drivers, followed step-by-step instructions on V1 site, open COM ports, installed Arduino libraries and boards, and tried on both Arduino IDE and Platformio. … keep getting the following message. Been trying to troubleshoot for a few hours so decided id take it to the forum. thanks in advance

Uploading .pio\build\rambo\firmware.hex
avrdude: stk500v2_ReceiveMessage(): timeout

avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer

avrdude done. Thank you.

You got it from here so it should be already programmed. Unless to are changing something up

I had this exact problem. In my case my pendant (running off running off Serial Tx0/Rx0) was interfering with the communication. This is unlikely to be your cause, but address anything that might be impacting the communication…hardware and software…and try a new cable.

As Mike said, you shouldn’t need to flash it. That error message means it can’t talk to the CPU. The rambos need 12V power, but disconnect everything else. Make sure you are talking to the right port. Baud rate doesn’t matter when flashing.

This is probably it.

I was just about to write the forum…do I just cut the Kastar adaptor and hardwire. I have the adaptors from Ultimachine. I didnt see instructions anywhere… and Im a total noob when it comes to electrical components. Most probably this is the issue (smh).

Im pretty sure I kept re-reading the need for 12v connection … but I must have selective comprehension

hooked it all up… got it flashed…going to bed. Excited to finish wiring it up tomorrow

thanks for the help guys
