How to start?
So where do I start if I am interested in getting the pieces for this machine?
Thanks, Chris |

Chris,
Have you decided what size you want to build? What you want the table to look like? What kind of motors you want to use? Details like that. Have you read some of the build threads of people that have machines running? Some people start by building the table first. Others by starting the kitchen project. Just pick a spot and jump in. You have to find a source for the laser parts and you have to start compiling a list of what you are going to need so you know what to order. I forgot, you need a set of plans! Good luck, now start building. |

Hi Chris,
If you're like me you've scoured the internet for suitable machines and have settled on the MechMate (good decision). Now you've spent a while reading the forum and have decided to download the plans. Then I put out a call on the forum to find people in my area and a source of the laser cut parts. The local contacts are a valuable source of information about suppliers and cost of materials locally. I (and all the other MM builders I've had contact with) spent a lot of time designing the table (size, steel thickness, etc) and assembling a list of steel, bolts, power box electrics and electronics). Once you have the list, then you get to go shopping! |

How about reading all the sticky threads 1st.

Well, I wanted to know, a couple things first. Can I make this a closed loop system? How much stuff do i need to get cut? Not really knowing how much of it I have to design myself and how much can be bought is difficult. Not sure if I want to spend $100 to glance at the plans to figure out if the machine is the right one or not. Are there any brough detail plans of the machine I can look at that describe what needs to be cut and what can be bought online where?
I have 3 weeks to figure out which direction to go in. Being a newbie at building something like this, half the topics here are Greek to me. Thanks, Chris |

Chris, building the MechMate is pretty straight forward. There is a kit of lasercut and bent parts that you need to buy. The rest of the structure is regular steel shapes and most all of the cuts are straight 90 degree cuts. There is some drilling and tapping then everything is welded up. The only odd part is grinding the rails for the gantry to ride on.
You will need to buy motors, controller, power supply, cable, cable chain, rack, Vee rollers, a computer, software, and some paint. Reading the site should expose you to everything required. I think that you have made a good choice. |

You need some space where you can make a noise and sparks, a willingness to read the plans and some time to dedicate to online research, shopping, and the building work itself. Last edited by Red_boards; Tue 26 June 2012 at 19:22.. Reason: grammar |

Does anyone know which Oriental Motors would be best if doing a closed loop system? I mean which model?
Thanks, Chris |

No real benefit in a closed loop system, do a search on the forum, this has been discussed at length.

There are no such thing as future proof machine.... If there were, we should remain in the broze age...

Chris,
Even if you built a future proof machine - all it would be able to do is what a non future proof machine would do - even then you could explore the new parts from manufacturers talked about on this forum, like example - look at the new range of leadshine stepper motor drives, |

Thanks for the link. It looks fantastic. I'm looking for a driver/motor combo that will help me get smooth edges on my cuts. Something I won't need to go through and sand, is that possible? Going to do a lot of fairly intricate pattern work, and it would be a real pain in the ass to have to sand all of it...
Thanks, Chris |

In a word NO. I have worked on various platforms from the MechMate right up to multimillion Rand Big Iron CNC machines (Biesse, SCM etc) and even the work coming off them with super expensive servo drives and literally tons of mass in the structure still needed sanding, maybe to a lesser extent but it was still necessary. So you cant get away from sanding - spending a lot more money on the machine may reduce the amount of sanding but you have to weigh up the pros and cons - I know I enjoy sleeping at night knowing I dont owe a huge amount to some Bank or Financier thats probably stealing my money anyway.
