Hello everyone. I have converted my MegaTronXY X1 into a CoreXY Printer. The printing area is 400x450x370 I read all about how fast the corexy printers print so I wanted to take a shot at it. So I tock my MegaTronXY X1 printer frame and I made it into a CoreXY printer. the Ramps full Graphic Display 12864 Case and Mount can be found here https://www.thingiverse.com/thing:1343964 any Ramps1.4 case will work, I just wanted to use the Graphics display from above to make it easy to adjust the screen. I have 3 types of Anti-wobble inserts to add which stop any and all wobble. you can either drill out the Zstagecarriage_100mm v2 or edit it to have the anti wobble inserted in the carriage platform, I just drilled it out and then glued it in place once I leveled the carriage. This conversion uses the same frame mounts found on my MegaTronXY X1 and parts/supplies from Lowes and Home Depot. This can be built with either 3/4 aluminum square tubing or 1 inch square tubing. the frame mounts are scalable. just resize for 3/4 tubing. You can also use the 3/8 aluminum rods from Home Depot and Lowes, they may be .5 mm's smaller but they work just as well. You can look at my MegaTronXY X1 here https://www.thingiverse.com/thing:2326560 and check out the tubing mounts. and I borrowed the X and Y stepper mounts from here https://www.thingiverse.com/thing:1849704 I've made some changes to the Z axis bed support and there is no wobble what so ever. I've also added level springs and screws to make the bed level. Haven't needed a auto level install since I can adjust the bed. Everything was made from 3/4 square tubing or 1 inch square tubing which you can get at home depot or Lowes. the heatbed consist of 4 120 watt glued on mk heat plates which can be purchased on Ebay or any 3d printer supply store. They were glued on with Fireplace caulk which can also be purchased at home depot or Lowes, the screws were 3/4 and 1 inch self drilling metal screws again purchase at Home Depot or Lowes. This model consist of 3 400 watt power supplies 2 of which are used for the heat bed and connected to the ramps 1.4 board with 12 volt automotive relays which are rated at 60 amps each at 14.4 vdc. the 3rd power supply runs the extruder and motors along with L.E.D. leds to light up the bed. Heating the bed doesn't take very long. The relays have their very own fans to keep them cool. On a side note, The Bed Z Motors are wired together in series to evenly raise and lower the bed. I'll be adding a new Hot end extruder Platform on a later date. This update will allow you to make adjusting the belts on the fly After test printing for more then 12 hours I found out the printed Anti-Wobble inserts failed. So I still use them in conjunction the Brass Lead Screw I was able to keep the anti-wobble working. and printing for another 12 hours the wobble still didn't come in to play at all. So I just drilled out 3/8 hole so I could insert the Brass Lead screw and it worked. Please see Anti-Wobble Brass inset picture.

I just started printing april of 2017. Been a Cosplay peron for alot longer. I got into 3D Printing because i've spent weeks if not months building Comic-Con and Cosplay props. Since i got into 3D Printing i've made, designed and printed all my Comic-Con parts. I use to buy my 3D Printers from eBay. In fact my first 4 were from eBay. 1st TronXY x1 with a print bed of 150x150x150 2nd Tronxy P802a with a print bed of 220x220x300 3rd Kossel Delta with a print bed of 180x300 4th TronXY X3a with a print bed of 220x220x350 Home Made 5th Mega TronXY X1 with a print bed of 440x440x300 6th EX Delta with a print bed of 220x452 7th Mega EX Delta with a print bed of 405x305 8th Corexy 350x350x400 9th Corexy 400x400x400 My latest design the Mega EX Delta, prints faster and quiter then any of myother printers. When i made the Mega TronXY X1 i wanted a larger print bed so i could print my Comic-Con/Cosplay props. Turns out it printed very good, however it tock forever to print large items. so that is when i made the Mega EX Delta. I did a time test with the Mega TronXY X1 and my EX Delta, Same parts same infill same specs on both machines. and the Delta Printed item in 8 hours, The Mega TronXY X1 tock 18 hours. That is when i redesigned my Mega TronXY X1 into the Mega EX Delta printer.
