I have have spent the past 2-3 days almost constantly reading up on this and now understand the scale of the machine that is required to meet my initial manufacturing requirements. Understanding this, I think it would be best if I took a step back and made something a bit smaller which can be used t...

Thanks for informing me of this, for the most part I will be machining hard woods however, if I do eventually need to machine mild steel, I will have to re-look at this. I have found the following guide for a small DIY CNC Mill which has dimensions that are perfect for my application (https://wiki.h...

Thanks for all the information, I didn't even realize that tools such as LinuxCNC existed! This will come in very handy. The answers have now created more questions: -I made a mistake in my earlier post, maximum mild steel thickness is 10mm which could be cut a very low speeds for long periods of ti...

As a project this year I want to try and build a RPi desktop CNC mill. For the most part I will be machining wooden blocks however, in some cases for short periods of time I will need to machine metals such as mild steel (20mm max thickness) which do not require a high precision cut. - What size mot...

Thanks for the replies, I will check the IP address when I get back.

The os on the RPi is Raspian and the laptop is running on windows 7.

I am trying to setup a direct connection between my windows laptop and RPi so that I can take projects with me to other locations without wifi and still have control over the RPi. I have removed the NOOB OS from my SD card and loaded Raspbian Wheezy and have had it all working on a seperate computer...

I powered the L9110S from the 5V rail. Obviously that solution is no good if your steppers/motors need more than 5V. If you want to use external power you will still need to connect a Pi ground to the modules ground. As the steppers I am using were from a DVD drive I think they will be similar to t...

Thanks for confirming this. Could you please tell me what you had used for your power supply to the L9110S modules at the VCC terminals?

Thank you, I appreciate you spending the time helping me with this. Up till now I was under the impression that the Pi would take care of all the power supply therefore, did not look into any external power supplies however, as you have pointed out, this is incorrect and I need to find an external s...

Thank you for informing me of this, I will read further into motor controllers. On a less related matter, I have purchased some L9110 dual H bridges (http://www.ebay.com/itm/350877288713?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649) to control my stepper motors, should it be OK to connect the ...

I have recently taken apart a few old DVD drives to see if there were any stepper motors available for a RPi project I am currently working on. When I opened one of the older drives I found a motor which was unlike the others as it only seemed to have two wires going directly to the coils. Is this a...
