Bed Levelling/Height adjusting screw/clips

I Use This On My Printrbot Simple To Keep My Print Bed Level. This design could also work with other 3d printers that require metal adjustments. Here is the upgraded version I'm using http://www.thingiverse.com/thing:257841, Jon Lawrence's modification to my machine. To be able to level my bed conveniently, adjust the height or tilt as needed, and maintain the heat bed in place at all times was what I sought out with this upgrade. In my case, the Z-probe on my printer never gave me reliable readings so I decided to make my own solution. The clips hold the Y bar and have been set up in a rigid configuration for stability and dependability with four holding points rather than just three which would not be as sturdy. As per your question, I made my decision after thoroughly checking out all of the options I had at hand and carefully selected the material and dimensions needed based on those calculations to provide complete support without compromise or excessive adjustment that can happen when 3D printing parts with this technology. It is pretty simple really if you follow the easy to understand images and see the step-by-step instructions for leveling the print bed as detailed below. As per your request, I relocated my probe slightly upward but decided not to remove it yet. Instead, it's simply out of the way but ready to be brought back into service should need arise from using this leveler and having complete access without obstruction if necessary so far has not happened during my extensive printing experiences thus far with no real necessity for this probe relocation which turned out unnecessary as originally expected after initial installation prior upgrading process that I found much easier now due in large part due entirely on your work product here presented within description following the format outlined earlier stated which indeed gave complete results allowing optimal use. Next step involves inserting code in order to get back home Z so enter: G28 X0 Y0; move X/Y axis to their respective minimum end stops G28 Z0 ;move z to its position where it needs be, for calibration Then you have got your leveler working perfectly by running this script through Repetier Host: M212 X0 Y0 Z0 After entering the commands as instructed in order move along properly proceed now next steps follow closely below: Moving On - Construct The Mounting Pieces To Hold Your Metal Frame For Printing Y bars should measure 200mm by 20 mm. Anything from 10-30m is possible width. Just have them run long at 150mm or longer depending upon desired fit with existing parts within overall system for better mechanical interaction that makes sense logically as far my expertise. As can be clearly observed, one screw should stick in a holding pin made from material M3 X12 that doesn't interfere significantly when print starts up correctly. One additional point I want to bring across while this explanation here now concludes completely - always test whether parts are fit and functional by assembling together first even without printed bed mounted properly until complete with hardware attached then move on manually checking operation smoothness throughout which indeed will prevent any major damage possibly caused by improper assembly of course due being part not designed initially by someone else therefore don't make assumptions but confirm prior doing work based info from these instructions following correct assembly as detailed throughout document below. If using metal parts they could become somewhat hard and tricky to fit sometimes so ensure their smooth engagement into desired area without too much effort or even possibly cracking anything while also giving room sufficient to install the spring. To make use of spring clips, take them on top attach with screws then place glass in order secure its position there you'll find that your new print bed looks incredibly modern but be cautious as springs can sometimes release by slight shock or heavy load making sure nothing comes off during printing which has yet to happen under heavy load conditions throughout my testing phase. Glass sheets like I found here at this specific pound store they also offer spring clips, http://www.poundland.co.uk/home-and-garden/kitchen/food-preparation/glass-work-top-saver , available at the given site, it works as a fantastic print bed surface when cleaned thoroughly first. Cleaning up after use leaves surface perfectly even which doesn't interfere significantly and also leaves nice imprint overall without leaving any extra residues so make sure you clean these pieces correctly for perfect use throughout.
