anyone know an easy way to add a pause using simplify3d?

Yes. That is how it should work. Set up a process for the whole print then add the stop point like layer 20. Add a second process (a clone of the first one) and just turn off the stop point and add the start point like layer 20. When you hit prepare to print it will pop up a box and select the first process and it should run to the selected level. Make your change and hit prepare to print again and select the second process and it should continue. May take some experimenting to see how it goes.

is this if the printer is hooked up to the computer directly? what about if i print from an sd card?

thanks
