Rambo 1.3L TTL Questions (Laser issues)

Can not believe I didn’t think about the floated ground! Thanks Ryan I’m going to try all of that and get things moving again! Not gonna lie I told my wife I wouldon’t break anything (she wanted to use the spindle to cut some stuff…) so I’m eager to get it back to basic operation!

Ryan,

I have refreshed the base firmware from : GitHub - Allted/Marlin: Optimized firmware for RepRap 3D printers based on the Arduino platform.

Here is the output from the serial monitor:

Unfortunately with just the XYZ motors connected I get no movement on G0 commands.

Some days you should just NOT mess with things, new born baby sleep brain is one of those times!

I appreciate all of the help and explanations!

That is not my firmware. Have a look at the firmware page on how to use github and select the correct firmware.

Well im just gonna see myself out… Man I thought a month of paternity leave would be a good time to dig in to this and get a laser up and running… you really need all your brain cells and sleep! Im sorry for the dumb questions… im back online. Thanks Ryan. I have no idea how I got from yours to base marlin… Thanks again. I think I will just work with M106/M107 for laser control for now… maybe after a little more sleep ill tackle M3/M5, right now im just glad to be back online.

Well the Xmas rush seems to be tapering off a bit. Once I clean up around here and get a little ahead I will be digging into the laser situation. Hopefully I can make it a little more straight forward.
