The machine is holding up great.
But if I were buying now I would go with the motors from CNCrouterparts and gecko drives. Maybe the 4 axis kit.
I would not change the spindle or the inverter.
I...

The problem with the 4th axis was the stepper motor was bad. I had to get the guy in china to ship me a new motor. It has worked fine, although I have not used it much.

I built a 48x48 crp machine. You can see the build thread here.

If I was starting over I would build it 5.5ft x 12ft.
I am cut alot of mdf and the sheet is 49 in wide. I can get it on the...

Just did the first cut on my harmonic drive 4th axis last night.
Just a simple banister like shape. Used Aspire to lay it out.

Had some trouble at first with a very slow feed rate on the 4th...

Gerry,

I have been using the processor for Aspire that was posted on here and it works great!

But I just added a 4th axis and have to use the Mach/3-WrapY2A ATC(inch) processor. The problem is...

While waiting on a new stepper for the 4th axis, I have been trying to solve my ghost e-stop problem.

I got it working tonight, but kinda bypassing the problem.

I bought a triplight isobar...

I think the 4th axis motor is bad.
I took it off the harmonic drive and the motor will not turn by hand.

The reason for the upgrade to the PMDX-126 was so I could add a 4th axis to the machine.
I got the 4th axis from ebay with the 100mm 4 jaw and 50:1 ratio.
It is the same one that is talked about...

I am trying to install this same 4th axis and I am running into some problem with the motor turning.

When I try to jog it in mach 3 it just makes some noise. I even unbolted the motor to see if...

Is the Geckodrive G203V supposed to come with a pack of resistors?

If not, What Resistor do I need for a 2.8a stepper. I only see 2.5 and 3 amps listed in the manual.

The cable to from the vfd to the motor is 4 conductor shielded flex cable with the shield and ground wire grounded to the vfd. Do I need to run another wire back to the ground in the box from the...

I have been just the breakout board of my machine to a PMDX-126 from the little one that came in the longs motor kit.
But now that I have the new board installed I am running into random ghost...

How do I need to wire/solder the usb ends on the cable. It is the same wire to the same solder point on each end or do they need to cross in some way.

Question on the 4th axis.
I am trying to firgure out the way to wire it to a gecko.
How do you have the stepper motor wired.
Mine have 4 wires, red, green, blue and yellow and is model...

I have been upgrading the breakout board to a PMDX-126 this weekend. To get more features, inputs for a 4th axis.
But now that I have the new board installed I am running into random ghost e-stops!...

I am about to order one, but I have a couple questions about the 4th axis you are using from ebay.

I assume you are using the stepper that came with it, if so what is the speed, acceleration,...

Do you have a exact suggestion on the cable or vendor?
All I can find is flex 6 conductor shielded 22 awg for $5.91 per foot?

Here is my dust collection system am using.

I use a harbor Freight 2hp dust collector modified with a self made top hat cyclone, Wynn filter, and lots of alum tape to plug every hole.

I got the...

No post in a while but I fixed the broken coupler. I used a lovejoy coupling.

I think it broke because of the length of my motor shafts. The shaft when into the coupling over half way and doing so...

Broken Coupler

Today I was cutting a job for a customer and while lowering the z axis for another cut the helical coupler broke and the z axis fell and drilled all the way through the work and the...

Is anyone running one of the 2.2kw spindles below 12000 rpm? I was just wondering if it can go lower without much drawback. If so how much.
Other than the frequency what settings to change?

I...

I had to remove my rack brackets for my y to move the rack to the other end. I just used a flat screwdriver and hammer and pryed each side evenly from inside the t channel. It took me a bit and got...

I have been trying to finnish up the cnc machine.

First I had to unmount all the motors and put locktite on all the pulley set screws to keep the wiggle out. I also remounted the z axis so it is...

I fixed the wiggle. It was from a loose set screw on the pully on the A motor.
Thanks to Ahren of cnc router parts

Somehow the cnc has developed a wiggle on the x axis.

I have the 2 motors for the x axis set as x and a. I have a slaved to x in mach. When I move the x axis one side moves (the x side) then the...

Video of Modbus and cooling setup with x200 vfd,

I got the Hitachi X200 vfd with a chinese 2.2 kw spindle working using modbus control from inside Mach 3. Use the instructions on this thread.

There is a problem with the brain that makes the...

L1/L2 (black/red), L3/N (neutral), and Ground to the ground tab
is how I have it wired using #10 wire to 30a breaker
