Re: New X-axis plates

Just a reminder that you will also need a longer piece of makerslide along with the misumi to expand the x axis. Thought I would point that out as it was not explicitly stated in the original post.

P.S. I like the new design!

Re: Makerslide - is it really so special?

@ northbear: But the "weakest link" in the system is probably somewhere else. If I had to guess what would break first when pushing to the limits (with larger router, motor, faster cutting speeds ect) I would guess the Delrin v-wheels. If you have a look at the picture I posted you can see, there i...

Re: Makerslide - is it really so special?

I am going to scale up once I get standard one to work. I am thinking 1m square. I will also see about doing some structural analysis in Inventor once I get the inventor models from Edward. Look like someone has done a similar exercise in Solid works http://www.buildlog.net/forum/viewtopic.php?f=30...

Re: Makerslide - is it really so special?

3.) Scaling: Want a bigger Shapeoko? Get a longer piece of makerslide! Because it's structural (see #2), there is no supporting hardware to scale as well. Most of the fixed costs are on the wheels/bearings/spacers, so to up-size your machine doesn't require anything more than longer makerslide. I a...

Re: Rotozip or Laminate Trim Router for the spindle?

Edward,

Thanks so much for the feedback! Exciting to hear how well it works. I am curious to know what the limiting factor for speed would be! Rotary tool, frame, motors, ??? I am not suggesting you push the limits until something breaks, but if you do let us know about it! ;)

Re: Is this a good stepper driver?

I picked up this driver and have been using it for a few weeks. It came with minimal documentation but it was easy to get up and running. I am using the 4th axis to drive the secondary motor on the Y axis. I will report back if I have any troubles. http://www.ebay.com/itm/CNC-Router-Mill-Machine-4-...

Re: El-cheapo drivers

I don't have any first hand knowledge with this stepper driver board, but on the CNCZone Forums, it seems this driver has mixed reviews at best. http://www.cnczone.com/forums/general_electronics_discussion/110986-how_i_fixed_my_chinese.html http://www.cnczone.com/forums/stepper_motors_drives/139306-...
