Voxel ~ Adventurer3 Bed Level/Angle Adjustor

thingiverse

Flashforge and Monoprice want you to take apart the top of your machine to adjust the bed level (or angle) via the ball screws. You need to remove the belt tensioner and adjust one of the screws up/down. But I found while putting the tensioner back in, it would move one of the screws, and I had to do it over and over and over.... that sucked! So here is my solution for this. On the bottom of the bed is a 604Z ball bearing in one of two captive holders. I designed a bearing holder to sit between these two holders and allows the bearing to pivot up/down. This allows adjustment of the bed **WITHOUT** messing with the ball screws! I have also designed a Holder for a Digital Dial Indicator. This attaches to the X rail. You may need this to help balance your bed once you install the Bearing Mod.

I did my best to capture everything. ------------ ###McMaster-Carr Parts: - 1x 9271K88 Torsion Spring LH - 1x 9271K87 Torsion Spring RH - 1x 92855A422 SS ***Low-Profile*** Socket Head Screws with Hex Drive, M4 x 0.7mm x 25mm ###Amazon Parts: - 2x 4mmx8mmx3mm Bearing https://www.amazon.com/gp/product/B082PPQ286/ - 1x 4mmx45mm Stainless Dowel Pin https://www.amazon.com/gp/product/B07YKYYY52/ - 2x M4 Washers - 1x M4x90mm FULLY THREADED Socket Cap Screw - 1x M4 Nut (to lock the Cap Screw ^) - 1x Brass M4 Insert - "Green" Threadlock (**DO NOT USE RED OR BLUE**) ###Printed Parts: - 1x Bearing_body - 1x Bolt_Block ------------ #You will need to modify your bed. Your warranty is now void! ###Bearing Adjuster: 1. Install 2x 4x8x3MM bearing on each side of the printed housing 2. Install 1x 604Z bearing in housing with Low-Profile M4 bolt (you will need to trim some of the threads) using a locknut. Place an M4 washer on **EACH** side of the 604Z bearing to keep it from rubbing. 3. Slide 4MM dowel into 4x8x3MM bearing (you may need to grind off about 1mm from length) 4. Slide torsion spring over the dowel, in the orientation of the image above 5. Secure the torsion spring arms under the M4 nut and cap screw. ###3D Printer: 1. Remove bed heater (2 screws) 2. Remove bed base from the rail (3 screws) 3. Clip or cut away part of both bearing housings on the bottom of the bed (see photos) 4. Install Bolt_Block with M4x80mm bolt on the *FRONT* edge of the bed 5. Insert the completed Bearing Adjuster into the plastic bed as shown in the photos 6. Install the dowel retaining plate on the bottom of the bed on both captive holders 7. Trim lower torsion spring arm, so it does not rub on the printer floor. **DO NOT** cut the spring arm that sits against the bottom of the bed ###Opperation: ##The spring is intended to push the bearing adjuster UP at all times. The M4x90mm provides the adjustment to raise or lower the bearing, thus raise or lower that side of the bed. So adjust the M4 in or out in very small increments till both sides of the bed are the same. Lock it down with the M4 nut, like a jam nut. ------------ Since my printer was out of commission, I had my parts printed on an HP MJF machine. This worked for me and my Voxel. Your mileage may vary! I do not check this account often, so if you ask questions about this design, you may get an answer in weeks. If you like this and find it useful, please consider buying me a beer (I am beer operated)
