Now Cutting! - Auckland NZ
 

Hi Everyone,

Thanks for all your help in helping me to decide to go with the Mechmate open source router. I decided on this one because it is really a no brainer to go with based on the performance and reliability of the machine as compared to aluminum one's with deflection problems.

Anyhoo, I do have a bit of a dilemma that I could use help with. I will be needing to order electronics, and anything I can stuff onto an airplane masquerading as a golf kit of bike kit, etc.. In other words, I will have enough space to bring from america all the parts that I can, which would fit in a golf or ski, even kayak sports case, up to 40kg. maybe 45. I am wanting to bring anything expensive or hard to get a hold of. In the country I live in, most electronics are quite expensive in comparison to America. So any recommendations would be fantastic .

Also, what sort of router bits should I bring with me? Will be doing quite a bit of cutting of plywood, MDF, aluminum, acrylics, and polycarbonates. Also relief sculptural MDF stuff, and wood. Can anyone recommend some premium bits that don't wear that fast. I travel back and forth from America quite frequently, and would prefer to buy my parts in America as much as possible.

Many thanks,
Chris

Hi, just wondering, how heavy and how large is the parts kit?

Thanks,
Chris

I can ship to you. You need to get a freight forwarding company. I may be able to help with that.

I can also ship you the electronics control box parts as well. I can pack each pretty good and also put them in wooden crates. Each weighs about 100 lbs if you get them packed good. I can't recall the weight limit but if needed we can split it all out over 3 boxes. But for estimates on freight figure on the max weight the carry will ship and these boxe sizes.

29x19x8 - Laser Parts Kit
22x22x12 - Control Box Kit

Also if your coming to the states, I can ship the stuff to your states address each time you come.

Ok, great, thank you. That may work. I think if I at least order the parts that would be impossible to get done there, I'd be in good shape. Shipping costs a fortune from here to there though, and 200 lbs might be fairly pricey.

Would it be possible to just purchase the laser cut parts that require bending, and then get the rest shipped cut there?

Many thanks again for the help,
Chris

In the end it would still probably be cheaper to ship you all the parts after you get a "one off" price and the time and effort needed to find someone who will do that small of an order.

The parts I've gottten from Mike have all been top notch.
I'd be leery of buying the first set a new vendor attempts to produce as a one off.

Ok, sounds good. Probably right. Is there a price list somewhere?

Thanks,
Chris

Laser Head?
 

Was just wondering about attaching a laser head to one of these. Has anyone done this yet? Seems like it would be entirely possible.

Chris

Gecko 213v drivers any good?
 

Is there any benefit to going with the G213V from Gecko?

They say they are configurable in steps. Also, will the new gecko with a motion controller in it be any good to use with mechmate?

Thanks,
Chris

For cutting it would be possible but not for engraving, as you need a lot more of speed and acceleration for that.

You can do it any way you want. If you see that someone posted using something than its possible. If you don't then its up to you to try that.

We all run our drives in 1/10 microstep, its because that is smallest microstep resolution bigger than the motor positional error. All geckos work 10microsteps, this G213V has a switch to adjust it. You could use it but only if you need 1/5 or half stepping to gain more speed at same mach3 kernel speed

That would be fantastic for cutting. Especially as an alternative to router for smooth edged detail work.

Great, thank you.

Just be prepared to pay 1-2 mechmate costs for a nice laser source

Have you done any research at all on your own?

Chris,
Try doing a search for things on the forum. A quick search for 213v turned this up. :) Here for the answers to your question. Take note particularly of Brad and Mike Richards responses.

Also no need to use quotes if the reply is to a previous post. :) See Using quotes when replying to a post - only use if essential please

All I've been doing is research the past couple weeks on this. And really grateful for all your help as I don't have a lot of time left before I have to get back to NZ. I've literally changed my return flight in order to source these parts and buy what I will need in order to build this while in the US. So please excuse me if I am asking a lot of questions that would likely be found after hours of reading through the forum. Kind of up against a deadline before having to fly away.

Advanced electronic parts in New Zealand are very difficult to come by. In most cases, they would just be special ordered from the US, which would cost a fortune in shipping. Since I am a total newbie at building a CNC, I've first had to figure out how it all works, then figure out what pieces I will need to bring back with me from the US.

So again thank you guys for your help.
Cheers,
Chris

You can get a 150W laser tube for $1381.99 on Ebay right now. Might be useful in cutting plastics and acrylics.

What part of the states do you usually travel to?

Great thanks! Very good answers indeed.
Chris

CA, orange county area :) Just hanging out till I figure out what to bring back with me. Seems like I will need:

Drivers
Motors
BOB
Smoothstepper Etnet
Wire
pulleys, cable carrier

Maybe some bearings?

Anyone know which option I should tick when ordering the G203V:
CW/CCW, Standard, or Vacuum?

Thanks,
Chris

Little bit more to it than that, laser power supply, laser controller, laser software, and the ability to make it go together.

Found a source for what pieces would be needed.

With a chinese 150w laser, it may be affordable to do?

Chris

Its a crappy glass tube. Not very precise and durable. You can get around 500 hours of work from that. They only last longer if you don't use them at maximum power.
Thats what all my laser cutter friends say. One got his machine on fire.

Build a machine, mount a cheap router, do some work and get to know your machine. Then upgrade at will and inform us so we can do it too :)

If you read a little bit of a G203V manual or similar stuff, or some posts on this forum
it should be clear that we use Step/Dir signals from Mach3.

So STANDARD version it is.

If you are in a hurry, and don't know what to buy. Get the complete kit from MetalHead, lasercut parts, electronics, motors, control box etc.
You will get exactly what you need and without loosing weeks to source, ask on forums, and wait for delivery.
My advice.

Very good advice, Danilo.

I agree as well, in this case. Think of it this way - even if MetalHead were charging 40% more than he should (which he isn't), you would still come out ahead of either ordering from home, or making a mistake by rushing here. It's a fair deal on proven configurations.

Believe me, I would if shipping to New Zealand from LA weren't so expensive. 200 lbs quote in that size is well over $1500, not including port/duty. I don't have the budget to waste money on shipping steel unfortunately or I would. I will buy the parts for sure from Mike when I return, or even maybe before I leave to put together a US machine. I'm sure they are top notch as everyone has given them aces!

Sorry for being such a nuisance. I do appreciate the help. Thanks a lot for bearing with me here guys.
Chris

Thank you for clarifying that. Very sorry for not reading the manual first.

Hi, I've been reading through all the motor threads and thanks for all the info on them. I'm still having quite a selection difficulty with the motors.

My first choice is to use the PK296A2A-SG7.2 as recommended, then I heard the PK299 - F4.5a with a 4:1 belt drive was cleaner and less backlash. But then I heard that the PK296-F4.5a running bi-polar parallel were just as comparable and delivered 1000ipm. at 1200 oZ of holding tourue. This is a smaller motor but faster curves, less torque at $157 USD.

What I'm looking for is the ability to cut cleanly through plastic, aluminum, and MDF/Wood. With as little sanding as possible required. Can anyone suggest the optimum Oriental Motor config for a 5x10 table running a 4hp 100mm Chinese Spindle please? I have G203V.

Thanks,
Chris

Before you order your motors let me price them as well. I am now setup to sell Oriental Motors direct. I can do the PK296-F4.5A for $139.00 each plus shipping. I will be away from my office though next week and not able to ship any stock parts. I will only be able to drop ship. All OM are drop ship items.

Does this mean that any questions I ask about motors, etc, are moderated and moved to this one build thread? Kind of defeats the purpose of having a forum.

Seriously???
Exactly how does this defeat having a forum?
Your posts are all in your build thread, instead of spread throughout the forum
Yesterday, you asked the exact same question in two different spots moments apart.

Asking the same question multiple times in different spots will get you an answer no quicker.

Believe me, going back later to reference an answer to a question will be a huge time saver.
Mike is offering to try to save you a few bucks.
Read my build thread, my motor choice and power supply is listed within and I'm very happy with the choices I made.

Enjoy your buld.
Edited to add: You've been asked nicely by two people to refrain from quoting posts in your replies, I'll nicely ask as well.

That's simply untrue, I asked this question in the motors area where it was, before it was moved here, it defeats the purpose by having a communist sensored forum in the place of a free thinking open one., one where ideas are exchanged, experienced shared , and no question is too stupid or boring. You people sure do have a lot of time on your hands to be bothered by some inquisitive newbie's posts dirtying up your perfect forum. I'd appreciate the right to post in any section I see fit without the whining or censorship. Nif this place is too childish to afford me this basic privilege,a dn my posts continue to get moderated into my own thread, I' ll quite happily shitcan this project and do a different one.

If you ask all of your questions in your build thread it helps us all keep track and help you with your build. I moved the post trying to keep us all in line with what your working on. So if you would like to chat with me just let me know and I'll give you a call. All we want is for you to have a successful build. You can see with over 100 machines registered that this format works and works well.

Chris, that childish tantrum was uncalled for.

This forum has 25 000 registered members. It is a popular reading place because it is relatively easy to read. You have decided it is your right to spit on the floor of our house. If this were still my forum, I would expect an apology or I would kick you out. Your absence here wouldn't cause a ripple .... in fact it would calm the water.

If you decide to build a MechMate, its not for our benefit - it will be for yours. We have built our machines by learning from the forum and from others that walked the path before us - it serves us well. Accusing us of being commies and closed minded will not get you the help you seek, I agree an apology is in order. :mad:

Ditto. (always at least once a year this troll behavior pops up)

Chris. There are many people here, like myself, that dedicate our experience to sharing with the forum on a daily basis since 2005. If you see the folks that are chatting directly here to you hold some of the lowest serial numbers. We are the beta group. We are the voice of experience that have built and watched others build 100+ machines.

If you would like sage advice, it's here.

Please respect the platform here, we all do this to keep it professional, friendly and accessible to all.
