Brim Prints, Part does not

Hey everyone,

I just completed my RepRap conversion on my printer.

Everything works great, the conversion of my CubePro was a great success!

I have my extruder stepper set for the correct steps/mm (that was a good hour and a bit of my night)

I sent a test print to the printer and the brim support prints fine, but when the print gets to the actual part, the extruder seems to stall/constantly skip steps. Is this an issue with my firmware? It extrudes fine when I do it manually.

I’m using Cura slicer and I will throw my Config.g below

Any help would be amazing!

Thanks,
Jake

is it that it gets to the part and doesn’t print or is it that after it’s extruded that much filament? my feeling is your cooling isn’t working as it should and the nozzle starts clogging after a while. is that possible?

Have an initial look at your config.g it looks ok, Can you post the Gcode file? think it may be cranking up on speed or down on temp. The Gcode would tell though
