Quick tips for Octoprint on the Creality CR-10

A quick setup tips for getting Octpprint to work with the CR-10. Make sure you use good quality cables to connect the Pi to the printer and also make sure the power supply to the pi is giving enough power to keep it up and going reliabley. Set the following on octoprint and it should work out great.

Baud Rate is 115200
Serial Port has to be set to USB (/dev/tty/USB0), Auto will not work.

Z-probe and height configuration for deltas using smoothie firmware

This is a quick method of configuring your delta printer If you're using smoothie firmware and a probe installed. Once you have the basics, rod length, delta radius and approximate height. Verify that your probe works with M119 gcode command.

Next, do a G32 to do an auto-calibration. Save with M500. Be aware this save additional info such as extruder steps, which might not be correct.

Set your Z-height/Z-gap

Lastly jog all the way to the bed use a dollar bill or card and then use M306 Z0.1 after calibration to set the offsets rather than mess with setting probe offsets.

Ensure that your carriage is moving the expected distance when you do a Z jog. Jogging down 10mm should move the carriage 10mm. This will let you know if your XYZ steps/mm are set correctly for your micro-step settings.

How to save a print that is losing supports

I was recently reading though the 3D Printing group on facebook when one of the members, Ken Jones, posted an amazing trick to save a print when the support structure falls off. Just use putty or clay to hold it in place.

I pause the print... remove the fallen supports... then put clay in across the horizontal gap, trying to make the top level of the clay as flat as possible and wide enough to serve as the new surface... I use the existing structure to anchor the clay on as well. It takes a little trial and error but eventually (when you get the clay slightly above the level of the print so the extruder comes in contact with just a tiny bit of the clay on the first pass) the supports start printing from where they left off on the fallen part. There are comments on each of the pictures. If this is too hard to follow, I can try to post a better explanation. Let me know.

It usually take a couple of passes but eventually the support fills back in saving the print. Neat trick, hopefully this saves some headaches for some one in the future.
