Turn on both Heaters and let them reach operating temp. Note: this process takes a while and is normal. You can observe the process by pressing the HEATING ZONE button at the bottom of the Control Panel

Install the Cavity mold on the MUD insert. (Remember not to force it!)

Install the Core mold on the MUD insert

To help do this, you may want to shine a light through the other side to elp with placement, or even put the pins in from the other side to ensure they are located properly

Also, don’t forget the sprue ejector pin!

Remember to spin each pin with your fingers so as to test to see if they bind. If they do not spin once inserted, change them out as they may be bent

Attach the back push-plate

Install the large bolt onto the Core MUD insert

Load the MUD inserts into the MUD Frame within the machine

Remember: if the inserts start to bind and don’t move easily, remove them, take a breath, and start again

Press and hold the Manual Mode Button for more than 3 seconds. (You should see a progress bar fill, followed by “SETUP MODE” at the top-right of the screen)

Close the Safety Gate

Test the ejector pins by pressing the -> Ejector button.

Retract the ejector pins by pressing the -> Ejector button.

This process is done to check that you have installed all the necessary ejector pins and the sprue pin, that they all properly eject, and that they still move somewhat freely in the mold. If your ejector pins are not all ejecting properly, remove the MUD insert and confirm you’ve followed the proper steps to set up the mold.

While still in SETUP MODE, press the -> Clamping Unit Button to close the mold fully closed. (The mold should move slowly during this process)

While the molds are closed, open the safety gate and turn the large bolt on the core insert counter clockwise until it reaches the surface of the cavity insert.

Turn the locking nut clockwise until it is tight against the core insert, thus locking the bolt in place.

This step will ensure the mold inserts will not “yawn” and create flash at the top of the mold

After the bolt is tightened against the cavity, set the position of the mold to zero by pressing the SET button on the pop-up number pad.

Close the safety gate

Retract the mold by pressing the -> Clamping Unit button

To return to the Main screen, press the "M" button on the bottom of the control panel

Check the Resin Hopper, (located on top of the machine body) to make sure enough resin is available. Add more if needed by removing the lid and adding about 1 coffee can of resin

Press the “SEMI-AUTO” button

Press the START button, (or open and close safety gates) to begin the run cycle.

After cycle is complete, open safety gate and remove part

Close safety gate to create a new part OR return to Manual mode to change parameters by pressing the MANUAL button

When finished with the run, remove all parts, make sure ejector pins are fully retracted, make sure clamping system (mold) is fully open, and finally, remove MUD inserts

Disassemble mold and return all ejector pins, shims, screws, and anything else used in this process to its proper home.
