Hi My Name is Todd. I am from Southwest Wisconsin. I am a project Designer for a EPC Firm in Madison WI. We design Wind and Solar farms.
I have a upgraded Shapeoko 2. My machine is 1m X 1.8m Gives me a cutting area of a little over 30in x 63in. I just got in to CNC about 3 months ago. I just got done doing an electronics upgrade to my unit which consisted of a C10 BOB and 4 SainSmart 2M542 Stepper drivers. running Nema23 Motors on all axis. 2:1 Belt drive on Z axis. With this upgrade I purchased Mach3. So far I love it. My machine is way faster and smoother.

Hi My name is Dave and today 1-9-15 is my first day joining. I have looked around and think this is awesome. I am definitely going to build a CNC router. I am good at reading and researching and building things but this is a whole new deal with the integration of all the components to make a quality tool. It seems most everyone is gracious in their replies and I am thankful about that. Not like the time I tried to learn to surf and practically got thrown out of the water by "locals".
I am looking for help, guidance, suggestions, and even moderate criticism if it gets me to a better understanding of the scope of work. My first question is how to go about this in the context of this forum? Do I start a thread on my investigation and build? If so where? Do I just find topics and jump in there? I would like to have a clear understanding of what works well but before I start. I feel I need to have a full understanding of the architecture of the system before I start shelling out money. My understanding so for is that I need/want:
1. computer/laptop running Mach
2. way to communicate through Ethernet
3. External controller
4. motor drivers
4. motors
5. other electrical such as sensors, relays, Estop, and things I don't even know about yet.
6. good mechanics, no great solid mechanics

I definitely plan on doing all the build myself.
Any help is much appreciated, maybe an overview of system architecture or some direction. Your words will not be wasted as I am very serious about this project. I'm even cleaning my garage if that tells you the level of commitment.

Hi Dave,

Welcome to the forum.

Perhaps start a thread (in one of the Show'n'tell sections) then you should get constructive suggestions on any build ideas you are planning. Alternately just join in on any threads that are relevant to your ideas - the choice is all yours and the most important thing is just to have fun whilst building and learning.

Hello, I'm new to using Mach 3, I have it up and running but I am having massive issues with homing and the spindle... Would appreciate any help anyone can give me.
When I try to "ref all home' or 'ref z' (doesn't matter which axis) i get the same error in that when it hits the combined limit/home switch Mach stops and says "external e stop requested"
My limit switches are hooked up to the same input (10) for Z++, X++ and Y++. A++ is separate (11) and the machine E-stop is separate (15). I'm using an ESS smooth stepper and G540 bob and I for the life of me can't work out why this is happening...

My second issue is the spindle (PWM controlled) takes about 3 minutes to ramp up to any decent speed, I can't work out why this is taking so long either but I have checked the average voltage on the output and it seems like it is the PWM signal that is very slow to ramp up rather than within the spindle hardware. Any ideas how i can fix either of these? I would love any help that can be provided!

Hi Dalymople,

Welcome to the forum.

This section is really just for introductions so I would be best if you post your questions, as a new topic, in the Mach3 General section where it will get seen by all and I am sure there will be many suggestions to help resolve the problems you are experiencing.

Hi
Not completely new here but was wondering if anyone can help me out with this problem.
Recently purchased Bobcad which is great very pleased. Having a problem with the Arc feature when posting to Mach3. I keep getting an error (RADIUS TO END OF ARC DIFFERS FROM RADIUS TO START).
I scanned the forums and noticed a few people had the same problem but not using Bobcad. I have tried in gen config changing from absolute to inc mode and various other things as suggested but still keep getting the same error.
Any thoughts anyone?

Thanks
Mick

Greetings everyone, total CNC noob here... I just ordered a hobby grade 3020 CNC Router off eBay and plan to get my feet wet within the next couple of weeks. I haven't purchased any software yet, but have been seriously considering Mach3 for my setup. I plan to place the machine on a shelf above my PC in my hobby room. I am an avid R/C Car Enthusiast who regularly races at the club level with various race tracks in my region. The only reason I purchased the CNC Router is to mill my own custom R/C Car parts to enhance performance and durability beyond what the industry is currently limited in offering.

Thanks!
Bill
