Hello,

So here's what I came up with for the x-axis:

Hello,

My progress has been pretty slow due to limited time to work, but I'll share some stuff:



The Fog Buster works fine, but I've mostly been cutting AL which doesn't really need coolant....

I spent time carefully measuring the worktable and found the problem. The worktable is modeled as symmetric from the left or right views. You can see this in the last picture of the previous post. ...

I spent time working through Hamzter's SX3 model in Solidworks. All the mates had to be redone due to the importing. I need to do the modeling for the X3 head, but for the mean time I've left the...

I've been looking closely at the ballscrews that come with the CNCfusion premium kit. They are obviously rolled screws if you look at the landing (and the price). The X axis nut on my mill is...

Hello,

I'm back to working on the CNC machine.

Does anyone know of a good solid model for the X3? I've looked around, but come up with nothing. I've got my machine in pieces right now and I'm...

I made the measurement on the fixed plate like I described previously. It seems to move around 0.001" which isn't as bad as I was expecting.

I have two values for my backlash on the X axis. When...

The motor side has no bearing. Just the motor mounting and a hole for the coupling to pass through.

Yes, it looks very much like that second drawing.

The original plate on that side (with the...

It occurs to me that I should be able check this in another way - by having the machine assembled fully and placing a dial indicator base on the table and the needle on this fixed plate somewhere...

My first thought was that the fixed plate may be rocking on the edge of the table. I tried throwing some big washers in there to allow more force from the table closer to where the ballscrew...

I would think about this like a ballscrew. You usually fix one end of a ballscrew with back-to-back ACBs or TRBs and let the other one 'float' with a normal DGB. This is so that as the ballscrew...

I noticed something interesting regarding the backlash on the X.

I took the table and the saddle and assembled on the benchtop:
...

I did a lot of work on the X gib. This scraping is a very long process. I'm sure it would get easier as you refine your technique and your tool, but for now it's a pain.

This is how the X gib...

I played with some blue last night. My photos were not uploading well so maybe I will post them later.

I was looking at the X gib specifically. First I checked it's actual flatness by blueing it...

The exact pulleys you order are going to depend on your motor, target speed, etc. For reference, here's the part numbers for the pulleys and belt I ordered.

Misumi: MISUMI, the catalog company...

My pulleys and belt came in today. They look pretty good as you can see here.

I worked on the Y axis tonight. Again, I tightened the lock nut on the end of the ballscrew (a lot more of a pain this time because of the confined work area). I got the same results. Started with...

Last night I was taking a closer look at the backlash in my X axis. I'm using the premium kit from CNC Fusion. I had been getting a pretty consistent 3-4mil of backlash depending on how tight I had...

So after all my planning to have a 120V or 240V system, it looks like I'm going to go strait to 240V. I was unhappy with the timing belt pulley selection at my motor's speed with 120V.

I ordered...

Probably too late but...

You can make those cables if you are having a hard time finding them. Mouser and Digikey have the mating plugs. Just make sure you order the contacts also as they are...

Hello. It's been a while. It turns out that eBay people are not fast... unsurprising I know.

Anyway, I now have my motor, controller, and cables.

The motor: Kollmorgen: AKM32H-ANCN2-00...

Thanks for the reply Rich, but I am hoping somebody has seen something similar off the shelf. I'm building a machine and I only need around 12' of this profile.

Hi Guys,

I am looking for a vendor or manufacturer for some extruded aluminum with this shape:
...

The cleaning we are referring to is the packing grease that the mill is covered with for shipping. All the exposed surfaces are covered with this thick, sticky grease to prevent them rusting during...

I don't see it on their site either. I bought my X3 from HF several years ago. The part number was 93885. You can always call and see if they will special order you one.

If cost is your main consideration (and $2k is quite low) then you basically have to go with a conversion yourself. Keep in mind also that tooling is expensive. At minimum you will need: some end...

So the previous post by Matt puts me in an uncomfortable situation. I don't like his tone and the manner in which he chose to give advice. I considered just ignoring the post completely, but I...

After a couple months of researching and thinking, I bought a new spindle motor yesterday. I looked at several motor technologies: brushed DC, brushless DC, and 3ph AC. I also considered keeping...

I measured the runout with a dial indicator when I mounted the spindle back on the mill. I wasn't using the dial indicator while actually tightening the preload nuts. Am I missing something?
