Electrical Hookup Questons.

[sierradays]

Hi Everyone,

Iam new to the forum. Ive been looking for a CNC Router for a while and bought a Cragslist Router this weekend.

It came with no electronics other than the NEMA motors and most wiring. The motors are labeled
23HS45-42004S

There are two motors on the Y Axis and single motors on the Z and X Axis.

Iam wondering what Stepper Drives and Bob to run?

Also, how do I wire up the two Nema motors on the Y Axis?

Am considering using Mach3 or 4. So I guess that mean a parallel port PC. Can I run a Parall port card or should I use an older PC. Is there a preferred operating system to use?

Are people running Touch Screen monitors, do they work with Mach3 or 4?

Any help would be appricated.

These are the motors.

I'd probably use drives like these, with a 60V power supply.

The two Y axis motors each need their own drive, and are slaved in software.
I would not use Mach3, or the parallel port.

You'd need a motion controller for Mach4, and can run any modern OS.
I'd look at UCCNC, which is considerably cheaper than Mach4, and is better integrated with their motion controllers, as they make both, instead of Mach4, which uses 3rd party controllers.

The Centroid Acorn is also getting popular.

A touch screen will work with any software.

Yeah, forget a PC based parallel port. I'd also avoid USB based breakout boards. For not a huge amount, you could grab any cheap PC with an ethernet port (even one of the tablet style jobs with a touch screen!) and go down one of two paths:
1. CNCDrive UC300ETH or UC400ETH controller card - you can run Mach3 or UCCNC software with this
2. MESA 7I92 controller card - you can use this one with Linux CNC

With either of these you'll need a breakout board with opto isolators (something like this one), a 12V power supply for the breakout board, a 48V or 60V power supply for the steppers and the stepper drivers. Not sure about the spindle, you may need to find a VFD to run it too.

ger21 and dharmic,

This helps to understand. I have a 110v VFD to run as well.

I am leaning toward the UC300ETH and run the UCCNC software. Seems there are a few version of the UC300ETH? Is this mainly just the chip and there are mulit configurations of this board?

Iam wondering about the C76-Multifuntion CNC board, I like the screw connectors on the board. Do you have any experiece with the Plug type over the screw mount connector on the board?

Would this driver run the 4 Digital Stepper Drive (DM860S) that you mentioned?

[ger21]

There's only one UC300ETH. But it requires a motherboard or breakout board that accepts it directly.

It normally is sold with the 5LPT motherboard.

I use the UB1 breakout board, and don't have any experience with the C76.
I prefer the UB-1 feature set, small size, and I like the push in connectors.

Yes, it'll run those 4 drives fine. (It'll actually run 6).

What should size is this machine and spindle? I ask because at a certain point it makes sense, to me anyways, to build the controls around 220 VAC in. I wasn’t able to make out the spindle class so I’m not sure of the power levels involved here. Anything above about 1.5 HP at the spindle would benefit from going to 220.

After taking a look for a second time at the gantry I suspect that it his machine will need some upgrades. It might be a good starter machine for you though. As such any investments made in this machine should take into consideration future upgrades.

As to your earlier questions, I wouldn’t consider Mach 3 at all as it is effectively end of life. You really have two options in my mind consider the more advanced so lutions out there or back together a cheap GRBL based controller. The GRBL would be cheap but offer the least upgrade potential.

Other solutions like Centroids Acorn, Mach 4 with motion controller, Linux CNC, UCCNC (and a host of others) offer use on future machine builds. They also provide capabilities that will never be in the Arduino based GRBL. The problem here is that mechanically I don’t think you will get much in the way of advantage from the advanced solutions on this machine.

The machine is 2'x4" with a 110v 3.5Kg motor. I on the same page with you about pouring a bunch of money in this machine, spindle and other things, This is my first CNC and my intent is to use this as a learning tool.

I like the UB-1 Board because of the contacts, but cant find it in the states,looking for domestic resaler. If I went the 5LPT motherboard, what are the plugs called, They look to be for ribbon cables. Would I still need a opto isolators with UB-1 motion controller

The 5LPT has 26 pin IDC connectors. I think the analog port is a 16 pin.

The UB1 has optoisolators on the board.
The UB1 is a breakout board. The UC300ETh is the controller.
Afaik, you have to buy it direct from Thailand.

You can set this up with the C76 and will work with Mach3, Mach4 or UCCNC. You can run CAT5 cable to connect to each driver using the C34KL board will have a very clean setup following this wiring diagram:
