STEP File Import

After reviewing my latest posting, I noticed that I was able to zoom and rotate the STEP files included with the graphics.  Dumb question - has the STEP file viewer always been included on Instructables or is this a relatively new feature?  Anyway, it's a nice feature for people that want a better understanding of the part.

3D Viewer

Instructables Team - I don't know when it was changed but the "View in 3D" upgrade works very well. I especially like the section analysis and exploded views.Makers - if you are like me and enjoy showing your work in CAD, please consider dropping STP/STEP files into your instructable.

Car engine stps running without ANY warning

My car: 2001 Honda Accord 4 cylinder, 95,000 miles Car always starts the first time I get in. I could be driving several days without any problem. Or It could shut off  every couple of days.  It's could even happen twice a day. Up to now it restarts after several seconds. Is there any answer? I'm at my wits end. Thankyou

Voltage from 4 wire bipolar stepper motor!

I've stripped a 1.8 deg stepper motor out of an old fax to make a bike generator but I can't get any juice from it. I'm spinning it using a multi tool so I should get something, right?! I did do some research and found out that 4-wire bipolar stepper motors are controlled differently from 5+ wire ones. I guessing then that generating power is different also. I'm reading 2.1 - 2.3 ohms off each coil. Tried wiring the coils in series but still nothing. I need a long serving instructablator to help me!! The label reads: STP-42D1020 1.8deg/STEP 2.1 ohms 33.5 V D.C. 0.7 A 17845G SHINANO KENSHI CO LTD. CHINA

CNC Stepper Motor and Controller Board Inquiry: What is the torque, motor size, threshold for dremel tool to engrave ?

CNC Stepper Motor and Controller Board Inquiry:Even with the extensive research and links I have visited it seems I got the cart before the horse with a bit of ebay bidding fever in purchasing my stepper motor.I just purchased 4 pieces new SHINANO KENSHI Co. ball bearing stepper motors Part # STP-42D201-36, 1.8 DEG, 200 Step/Rev, 3.7V, 3.1A/Phase, Size 17 with a 5mm shaft. I will be making a computerized dremel tool ENGRAVER (not cutter) to start. I do understand that a CNC, for cutting out shapes, requires more torque than the STP-42D201-36 will put out. I however wish to engrave, only partially cut into the surface of wood to render my artwork, some which can be seen at http://designermite.net/. These will initially consist of line work but then later I will render halftone work.I do own and work with Gerber Advantage 6.0 Premier and Omega software with Gerber HS/15 PLUS plotter creating vinyl graphics and logos that you might see on store windows, car, truck and van lettering. So I do have a working knowledge of the basic skills needed.I need help on what sort of setup I should be leaning towards that would work with my CURRENT purchase. What is the torque rating, motor size, specs threshold for dremel tool to engrave properly?Some have been very helpful via email and for that I thank you and others have just lived up to thier names of being cranky, claiming they invented everthing under the sun, with short two word sarcastic answers when I actually wished to purchase their plans.. go figure.Thank you in advance for your timecnc, stepper motor, stepper motor control board, computerized router, engraving, CNC Router Plans, cnc engraver plans, CNC http://designermite.net/Homemade Milling Machine, homemade DIY cnc mill router machine,x axis y axis z axis, GCode, Computer Numeric Control, robotic systems ,computer parallel port, step and direction, DXF, plot, plt

Stepper motor vibration/lockup with driver? Answered

I am trying to get a stepper motor to turn using a StepStick driver from Botronicz. I have gotten the driver to work once before, but now it has decided not to work. I have wired my stepper motor (Model STP-42D3018) according to any specs I can find online in a bipolar connection, but when I fire it up the stepper only sits there and vibrates. Or misses steps (depending on voltage). A few other times I had it also where it would step one direction for I think a single step and then step back the other direction. It is really bothering me because I have tried multiple other wiring combinations and have not gotten any of those to work. My current setup is exactly like this (I have checked numerous times). I have also tried changing the vmot supply voltage and current limit, as well as the current limiter pot on the board itself. If anyone can help it would be greatly appreciated! Sincerely,  A907
