Re: Stepper motors from Circuit Specialists?

Thanks for the response pourcirm! If I may ask how you decided on this motor from the plethora of motors about the same price at Circuit Specialists? Also I assume you are running it Bipolar? If so are you running it in series or half-coil? I am thinking about running LinuxCNC and so I am looking fo...

Stepper motors from Circuit Specialists?

Does anyone have experience ordering from Circuit Specialists? (http://www.circuitspecialists.com/stepper-motor) They seem to have good prices on fairly powerful Nema 23 motors. I am looking at something like 57BYGH405A - $25.50 - 291in*oz - http://www.web-tronics.com/nema_23_stepping_motor_57bygh40...

A belt on the outside idea for Nema 23 motors

I really liked the belt on the outside idea listed here (http://www.shapeoko.com/forum/viewtopic.php?f=11&t=436), but I am thinking of using nema 23 motors and since they use a 5mm bolt same as the idler pulleys I thought it would be cool to combine the two. So instead of using hex standoffs like th...

Belt tenison idea for a belt on the outside design

Thought I would share an idea I came up with... well at least stole from a couple of different places and put together :mrgreen: It uses the zip tie idea (http://www.shapeoko.com/forum/viewtopic.php?f=11&t=412) along with the adjustable tension ideas in this thread (http://www.shapeoko.com/forum/vie...

Re: Twisted X Axis Makerslide 180 degrees

@ northbear » What are you using to prototype the drawings, and does it export in OpenSCAD .. I am using Autodesk Inventor. I use it at work otherwise it would be cost prohibitive for hobby use! Regarding exporting, Inventor will export in many file formats (ie *.stp, *.igs etc) but I do not know w...

Re: z axis travel / working area question...

Edward, Thanks for the very helpful reply! It makes complete sense to me to align the bottom of the collett with the bottom of the makerslide. This way the makerslide should never interfere with the part. I had seen a video somewhere where the spindle was mounted so that the collett was up the maker...

z axis travel / working area question...

Hopefully someone who has actually built a ShapeOko can answer this question! I understand the limits of the x and y travel, but with the z I would like some clarification. Looks like in the upwards direction there is no hard stop and you could just run the z axis off the end of the nut. Moving the ...

Re: Twisted X Axis Makerslide 180 degrees

RSWeaverAz,

Is something like this what your are thinking of? (please note this is an *extremely* rough assembly with things just floating in mid-air, missing lots of parts, the parts that are there not constrained in place etc, etc.... Viewer beware :mrgreen: )

Re: Anyone have experience with HeeksCNC / HeeksCAD?

Still love CamBam :) The more I play around with both of them the more it seems CamBam is the better program. I was really hoping HeeksCNC would be a better program then CamBam as I would eventually like something that would run on linux. But....looking at CamBam again it seems like they are in the...

Anyone have experience with HeeksCNC / HeeksCAD?

Curious if anyone has experience with HeeksCNC? http://code.google.com/p/heekscnc/ Open Source, download for Windows and looks like a beta for Linux. I have played around with it a bit and it is set-up similar to CamBam (from what I can tell having very little experience with either one) Just seeing...
