Upgrade your Epax

I’ve owned my Epax X1 for about four months now.  I’ve used it a lot.  Those of you who have been following me, know that I do a lot of jewelry design, and that is a majority of my printing needs.

I’ve had a couple other printers, some very expensive, like a form 2, others like the Elegoo Mars.   All have performed good, and as long as you follow the printer instructions, match the resin and settings, you should be able to get great prints with all of them.

The Epax captured my imagination, because out of the box, for an additional hundred dollars, it had a larger uv lamp array, as well as a more powerful uv lamp power supply that, from my electronic experience should perform better.  This, however, was not the reason that I purchased the Epax X1.  I bought it because you could get it with a larger UV Lamp Array, or, if you were so inclined, upgrade to this better lamp yourself.

This is what I chose to do.  Check out my video, and let me know what you think.

What are you going to need?

For most of you, I believe that the though of opening up your 3d printer, and tearing into all the cables and wires is kind of daunting.  Don’t be too intimidated, it really isn’t that difficult to do, but plan on spending a couple of hours, and with the lack of written instructions, you are going to have to follow my video above.

Here is a list of tools you’ll need…

  1. Hex Wrenches, various sizes
  2. Plastic pry tools, small ones.
  3. Wire Ties
  4. Tape, electrical
  5. Small cutters, to cut the wire ties inside the printer

In addition, you’ll need to get your hands on the Parallel light kit from Epax, for your X1 printer.  At the time of this article, they are out of stock.  I imagine they will be available soon, but check in at their web site, send them an email or give them a call.  Their customer service is very good, and, located in the US.

What Comes in your kit!

When your kit arrives, a few days after you order it, these are the things that you’ll find within the box…

  1. The large UV Lamp Array
  2. New 30 watt power supply for the lamp
  3. A new Fan, which mounts to the underside of the lamp array
  4. Four different size screws
  5. Four spacers
  6. Two Mounting brackets for the Lamp Array
  7. New mounting bracket for the motherboard
  8. Small mounting bracket for the new power supply

Mind you, that in my review of the Epax X1, I mentioned how impressed I was with the build quality.  If you haven’t read my review, click here to check that out.

Once of the things that struck me about the upgrade kit was, of course, no written instructions.  I cover the installation pretty well in my video, but I’m not going to break down the step by steps.  The other thing that puzzled me was that the extra fan, which gets mounted to the heat-sink under the Parallel light has no tapped holes for the screws.  

The fact that this 3d printer is built so well, I can’t imagine why no one took the extra time to pre-drill the heat sink, tap them for the threaded screws, and just make this seem like a perfectly finished product!  You’ll note, that as you tackle this project, as  you can see in my video, you kind of have to lay the fan on the underside of the light array, and force the screws to thread into the two larger fins on the heatsink.  Hmmm.

That, though is my only gripe!  All else, is fine and built very well.

Digging In!

Like I said, I’m not going to take the time to write out the step by step instructions, because to be honest, I think I did a very good job with the video.  🙂  

Get your tools out, unplug the power cord, and start your process… 

Here is a quick list of the steps you’ll take, and in the order that you’ll be taking them…

  1. Unplug the power cable from the back of the Epax X1
  2. Remove both the bottom and back cover plates
  3. Using your cutters, clip the wire ties, being very careful, and remove them.
  4. Start by removing the mother board
  5. Remove the Large powersupply for the original lamp
  6. Remove the lamp and cone that the original lamp is mounted to
  7. make sure to follow the steps in the video for removing cables
  8. Add spacers and new bracket for Motherboard
  9. Connect video and touch screen cables
  10. Mount Mother board
  11. Mount the two brackets for the new Parallel lamp
  12. Mount the new fan to the bottom of the Parallel lamp
  13. Mount the lamp to the two brackets that hold the lamp
  14. Mount the small power supply
  15. Connect all the rest of your connections, fans, limit switch, z motor axis etc.
  16. make sure all screws are tight and in place
  17. Test the printer and make sure it works and the correct pattern displays
  18. Using new wire ties, connect the cables and button them up
  19. Put the covers back on

Thats pretty much it!  If you follow the instructions as I did them in the video, you’ll be fine.

Make sure you use extra caution when working around the lcd touch screen cable and the lcd display screen.  Those cables and the connectors are very delicate.  The connector for the touch screen is the most delicate connector.  If you fail to put it back correctly, you could damage the tiny little pins.  If that happens, you’ll have to either have the board repaired or get a replacement.  

So, no doubt you’re wondering was it worth it?  I’ll Let You Know in a Week!  🙂

Good luck guys, and if you have any questions, please post them and I’ll do my best to answer them…

Take care.. Peter
