Setting the Z height for additional printing room

When your printer arrives it's typically set at a moderate Z height. The problem with setting maximum Z height when we ship the printer is that if you're printing a small object it takes a long time for it to come down to the bat to start the print. If you're always printing objects 200 mm then you should set the Z height at a maximum of 250, let's say.
Now you want to utilize your 3D Potterbot to the maximum ability on the Z axis. First put a tube in the machine as high as it can go on the clamp. Now jog down the Z axis till the nozzle is almost touching the bat. Now take a tape measure and measure from the top of the car to the limit switch on the top of the Z rail. This is your maximum Z that you can enter into the configuration file.

To change this number power off the machine and unplug the power supply. Now plug that USB cable into your printer which is located under the screen. It should show up as a USB drive on your laptop. There will be two files and you want to open the config file. Look at the gamma_max (350), this is the number that you have to change to change the Z height in mm. Just hit save and that's it. Be sure not to change this file in any other way or the machine will not function. I recommend that you back this up before you even start in case there is a problem. Do not run the USB cable while the machine is plugged into the wall.

Simplify3d factory settings test prints link

These files are Simplify 3D factory setting. The real advantage with Simplify factory settings is that not only does it include the STL file, but it also includes all of the settings and parameters of the slicing program and options. So for our customers that have Simplify 3D it's as simple as double-clicking on one of these files, Simplify 3D will automatically launch and all you have to do is generate the G-Code. All of these files have been tested on our machines here at our shop. You might have to adjust your speeds and feeds but probably only slightly for your clay consistency.
