Problems running GCode from SD Card

Mostly Printed CNC - MPCNC Troubleshooting
1

Smart controller is hooked up and working. I can control all axis from the controller. It recognizes my SD card and shows me the files on it. But when i try to run a gcode file it doesn’t do anything. What am I missing?

How did you generate the gcode file? Are you sure the gcode file is good and has actual movements in it? Try a simulator like rep host or an online one like https://nraynaud.github.io/webgcode/. Is there any error displayed on the LCD? Can you paste in all or part of the gcode? Are you running marlin/ramps or another controller?

I’m running marlin/ramps. I have a min heat error. But no 3d printer head installed yet.

Just some gcode i snagged off the forums here.

Got a little frustrated and put it away for a few days. I’m at work right now but, I will get a copy of the gcode when I get home. I coppied the code from a test that someone posted on here. The one where it drew two square boxes and alternated between them. I did try sticking the code in a web simulator and it didn’t show anything either. Could’ve been my lack of knowledge on how to run the page. I’ll try your example tonight.I have a Min Heat Error. But I don’t have a 3D printer head installed yet. Was just looking to make it move first.

I appreciate your help.

You need the resistor on pin T0 to get rid of the min temp error, then you can visualize the gcode, kinda, in repetier by checking the show movements box.

I knew I forgot something! Thanks, vicious!
