Very awesome work so far. Looks like you are doing a great job.by PvtDBJackson - Object repositories
I made it myself in SolidWorks. EDIT: Also now on Thingiverse:by PvtDBJackson - Mechanics
Let me know if this works. This should fit the larger LME8uu bearings (16mm OD x 25mm L). All other interfaces were kept the same (hole locations, rod spacing, etc).by PvtDBJackson - Mechanics
What kind of valves? I do valve engineering at work. Mostly large industrial motor-operated gate valves. I can't provide you with the actual geometry of our valves, but I can probably make some simple scale representations.by PvtDBJackson - Object repositories
My gut feeling tells me that it is a retraction issue. What are your retraction settings? Might want to decrease your retraction length.by PvtDBJackson - Printing
QuoteBill Clark I'm new to these parts but my perception of the "whole" thing is just over inflated marketing. Apparently it worked though Bingo. Makerbot doesn't make money from Thingiverse. They make money from selling printers. You and I are here because we have mechanical aptitude and built our own printers. Someone that buys a Makerbot likely doesn't have the skill or time to build theiby PvtDBJackson - General
Quoteyasrkasem Hi, As Cat.Farmer said, (expected size)/(actual size) * current setting = value for steps But, you don't have to print and measure you can just move the X, Y & Z from the printer interface to 100mm from home and measure the actual movement then apply the formula. mostly the X & Y will be the same value but the Z is different. for the E, Just extrude 100mm and measure it onby PvtDBJackson - General
If SketchUp has a Loft feature, you can make simple bevel gears. I can provide instructions on how I do it in SolidWorks. Or if we can talk about the dimensions/constraints in your design and I can make and send you the models.by PvtDBJackson - Mechanics
QuoteChri Nice i was looking for a cone-gear generator to make some tests with a smaller version, but didn`t found any Chri You mean a bevel gear? Do you have access to a CAD program? Simple bevel gears aren't hard to make.by PvtDBJackson - Mechanics
I've been following this discussion for a while now and have been working on my own 1.75mm designs. It is hard to get an adequate feed rate. This is a two fold problem: 1.75mm filament already requires higher motor speed since there is less volume per mm of length, and smaller threads have smaller pitches requiring more revolutions to get 1mm of extrusion. This can be solved with additional geby PvtDBJackson - Mechanics
This can be set in Slic3r. If you are using v1.0.0, it is under the Printer Settings tab, then select your extruder, and change the Speed under the Retraction heading.by PvtDBJackson - Reprappers
Yes. You are correct. The 8mm versions do indeed go with 8mm rods. I recently put together a MendelMax using the same STLs. I have 8mm rods all around. I ended up using the X-Ends here: , but The spacing between the rod and the lead screws is too tight (28mm instead of 30mm), so my Z motor mounts needed to be modified to fit the motors. I've since designed my own X ends to fix this issue.by PvtDBJackson - Extruded Aluminum Frames
Yes, I have printed a ton of things already. It was so easy to get running. This is my first print: Thin-walled calibration cube. The guide I was following said that if you can get one good wall to print, move on. I got 4 nearly flawless walls (with a bit of the skirt lifting from the first layer being a bit too high). Now, a big part is my hardware. But following this guide: and puttinby PvtDBJackson - Controllers

You are losing steps along one of the axes. Could be a number of things. Just a few that I can think of off the top of my head: -Insufficient current to the stepper motor (increase current slightly) -Too much current to the stepper motor causing the drivers to overheat and cut out (motor will be hot, decrease current) -Pulley slipping on the shaft (tighten the set screws) -Belt slipping on theby PvtDBJackson - Reprappers
This is my review of the Minitronics v1.0 board from RepRapWorld.com First, a little about myseld, to preface my review and establish my experience (or lack thereof) in RepRap. I am a Mechanical Engineer. I was introduced to RepRap by my brother (a Plastics Engineer) who was given a Prusa Mendel by a freind of his. I've had some experience printing on his machine, but neither of us has everby PvtDBJackson - Controllers
Also make sure your pulley set screws are tight and your belt is properly tensioned. The pulley could be slipping on the stepper shaft. Or if your belt tension isn't tight enough, the belt could be jumping teeth.by PvtDBJackson - General Mendel Topics
I would create a Work Plane centered on the rail and one centered on the wheel then constrain those two. Then a tangent constraint on the wheel and the rail.by PvtDBJackson - 3D Design tools
