Ok thanks Nic 77 I will keep you in mind. Regarding controlling the spindle I need to figure out exactly what controls, spindle speed, ATC, and other sensors. This is my first build so I need to...

Ok so correct me if I am missing anything. Here are the things that I will use with my control. I definitely want to go with a ethernet cable.

Spindle speed control
Limit switches
Tool changer...

Ok great I will definitely look at those.

Oh ok. Got it.

Forgive my ignorance but why do you recommend those over Mach 3 or 4?

So to narrow it down which one is best for a servo system? Remember I want full capability with my spindle unit.

Yes I am definitely going with Mach 3 or 4.

To be honest I don't know what I need. I am relying on these guys to give me what in need in the package. So the input that you guys give me is supper helpful.

No they don't have enough inputs to handle everything.

Okay guys, I am trying to figure out what breakout board to use with my machine. It needs to be compatible with the 1kW DMM servos but more importantly I want to be able to control my ATC spindle...

Nic 77 Thanks so much for your help. I think I will have DMM look at your figures and see what they say. Thanks again

Here is what DMM said about sizing motors for my machine.
Hello Scott,

The 1.0kW motors would be a good size and you will need a belt reduction as well since the gantry is quite large. You will...

Thanks for the info. I did talk to DMM they recommended sure servo. I just wasn't sure about the quality. I know Atlantic sells some really nice stuff but it's super expensive. I am using a 20 degree...

Any suggestions on company's that sell good servos and gearboxs that don't break the bank. Keep in mind that I want company's with good instructions and service.

Ok guys I need some more direction. I am trying to figure out where to source my motors and gearbox. Once I have that nailed down I can machine the uprights and move forward. Does anyone suggest a...

Yeah I know what you mean. You need to break it down so it isn't to overwhelming. Once it is broken down you just have to piece it all together.

I picked that up at HGR industrial. I got a great deal on it. Great place to find deals on used items.

My wireway came today. I should be able to use this for all three axis's.

No I will have to look at that. Thanks

Yes well it looks like everyone agrees that 1KW servos should work fine.

The width is 18". I figured that should make it pretty stable.

Actually I have everything already welded up. My model doesn't show everything though. I welded ribs on the inside of the large gantry tube. These ribs will stiffen the whole gantry dramatically. I...

Lol. No problem.

Nic 77 My design is also made to cut aluminum sheet and other aluminum products. I will be purchasing a nice ATC after it is finished. I figured if I am going to do it, do it right the first time...

No 1800 IPM would just be the rapid but I will probably knock that down to about 1000 IPM because of the size of my gantry. My cutting speed will of course depend on what I am cutting but faster is...

Thanks everyone. I appreciate the advice. To move forward I am going to have the uprights machined so that a mounting plate can bolt to the face to hold the gearbox. Then I can machine the gantry...

Thanks Ger. We'll can anyone point me to a low cost planetary gearbox with low backlash? I believe a 4:1 should work.

Thanks Nic 77

Thanks for everyone's comments so far. I believe I will be going with a servo system. It looks like that is my best option to have continued torque while getting the speed as well. Now I need to...

Ok great. So I could do the DMM servos with a belt reduction system? Do you know where I might be able to find a well made belt reduction system?
