Pergo VER 2 Robo3D R1 (and plus) true 370 mm Y rails upgrade

thingiverse

You got a bed that's 15 inches long, but can't print more than 9 inches. That's not true anymore! With my mod, you can truly print on every square millimeter of the 15 x 10 glass. You might say wait, you can really do that because PLA and ABS will peel off the bed once you get past the heater. Right, but with my 600-watt bed heater upgrade, I can truly print a 360-millimeter long object that won't warp off the glass. Some extras about this version: This part is more accurate, durable, and a much better fit than the Version 1. That's saying something because I printed with my version 1 for about two years. This is a quality part with a lot of experience behind it. I really feel a difference in the smoothness of the glide down the full length of the Y axis. With the below print settings, these ends are even lighter than the Version 1's. That's due to the ribs I used on each of the glass supports. Another benefit is that the glass is now centered between the housing of the white case. I shifted the entire bed six millimeters to the right to accomplish this. Print settings: Use six shells and a twelve percent infill, and print at .31-millimeter layer height if you can. Print the model as is for the Front piece and MIRROR the part Z axis for the Back part. Position the part on its back with the legs sticking up, then rotate to 45 degrees to make it fit on your bed. Print the Front (part)... Then print the Back (part)...... Cura: Select Part, Mirror, Y, Print it. Matter Control Users: Select EDIT, then Click Mirror Y, Print it. Simplify3D: Menu item [Mesh][Mirror Mesh][Mirror Z], Print it. Others: Buy Simplify3D! Really, it's awesome! Install: Now you have the part and a mirrored version of the part printed. Get a drill that's closest to 8 millimeters but a tad less, and drill out the spots where the 8-millimeter rods go. Leave at least four or five millimeters. Don't drill all the way through! Lay your glass and the ends on the floor facing the floor, and measure the rod length you need based on how far you drilled your eight millimeters into the end holes. Measure the length of rod you need based on how far you drilled. For me, it was twenty inches long. Cut two of the 8-millimeter bars to a length of about twenty inches based on what you found above. It's better to be a bit long than short. You can cut again. I used a Dremel Sawmax with the metal cutter grinding wheel and wow, cut like butter! Don't jam the eight-millimeter rods into the ends yet! You might not get them out with the tight fit, and then you'll break the ends getting the rods out! Put the rods in the Pillow blocks (the rectangles that hold the 8-millimeter bars on the printer). Do a test fit with the length of your rods. Happy with the test fit? Now you can put the rods into the mirrored Back end you printed. You might have to use a hammer to get them seated all the way. Then, with the rods still in the Pillow blocks, put the printed Front end on the 8-millimeter rods. If all is good, now install the new GT2 belt. Test fit it by making sure your belt teeth are to the left as you look at the front of the printer. Put the belt ends into the retainer blocks from your old bed. Make sure that your belt has a bit of slack. Best to be long and cut it down when you see how much you need. Tighten the front and back screws, taking up the slack until you have good tension on the belt. Rock your bed back and forth making sure you have a good "glide". At this point, you're ready to see if your printer likes the new bed. Keep in mind that we did not flash the printer firmware yet, still giving you a way back if something is not right. Tell your printer to Auto-Home. If you like everything you see, go ahead and flash the printer with either the firmware I provided that will specify 0-370 millimeter Y max length. I also already have the Graphic Controller in this firmware. Here are the values I have in this version for max limits: // Travel limits after homing #define X_MAX_POS 214 #define X_MIN_POS 0 #define Y_MAX_POS 370
