I am in the process of replacing the X and Y axis servo motors and encoders on my Industrial Hobbies CNC Mill. I am using the 850 oz/in Keling technology KL34-170-72 servo motors equiped with CUI...

The best solutions are the ones that are simple and clean . . . you have both . . . great installation.

Good solution . . . I really like the 850 oz-in motor as it powers the mill head up/down smoothly. Can you post a picture of your installation so others can copy your solution?

Unfortunately, during gib adjustment on the Z-Axis of my IH CNC Conversion Mill I locked up the Z-Axis and burned out the servo motor. I contacted Charter Oak Automation and Paul was very helpful in...

I have squared the tower using a "Square Cylinder" (see: CNCCookbook: CNC Mill Tuneup) and dial test indicator to the limit of accuracy (0.0005 inches). When facing the mill, I had to place .004 shim...

Not all breakout boards will work properly with the Industrial Hobbies optical limit switches. I happen to think the IH CNC limit switches are ingeniously designed and work effectively. As I have...

Having recently purchased BobCAD V26 and have set up milling files for a client to machine a complex steel part in both V25 and V26, I can say that V26 will give a better finished part quicker in V26...

I am very close to machining the first cut on my Industrial Hobbies Mill CNC conversion. The last missing piece has been the coolant manifold. I designed and machined on my Taig Mill a distribution...

I machined some simple stop blocks for the x-axis on my IH CNC mill from some leftover Fortal Aluminum scrap that fit the front edge of the milling table quite nicely. The 3D CAD drawing can be found...

This morning I ran a motor test for the first time on my Industrial Hobbies Mill CNC conversion. I finished the CNC Control Enclosure wiring for the first axis (Y) yesterday and turned it on today. I...

My shop is an add-on (by the previous owner) to the back of my house and no electrical was run when the room was framed in. I had a professional electrician add the 110v power several years ago to...

The final adapter needed was thicker than the initial design because of the need to use a shaft adapter. The final design which has been machined can be found as a 3D CAD drawing at:...

The cost of having a 220 volt line run to my shop is too expensive compared to switching to a 110 volt 1HP or 1.5HP 3450 rpm motor. For the initial test I bought an inexpensive 1HP 3450 rpm motor on...

My Xylotex board fried a couple of ICs recently so I replaced it with a Sain Smart TB6560 4-axis controller for my TAIG CNC Mill equipped with 3 Keling KL23H276-30-8B stepper motors. MY TAIG Mill...

My 2005 IH Mill has a serial number in the mid-1400s . . . so if the serial numbers were continuous, that would mean 500 or more imported since 2005.

I posted on GrabCAD (.stp CAD file) a simple adapter for a 56C motor to a B5 flange mount that will adapt 56C Electrical Motors to the IH Mill B5 Mill Head Mount. A Hallmark Industries 56C Motor with...

I find that when sending out 3D Solid Models to potential clients for viewing or for machining quotes that a platform independent format like Adobe 3d pdf has big advantages. I'll keep using my old,...

I received my copy of BobCad V25 yesterday afternoon and installed it last evening on my i7 cpu based PC with Windows 64. It installed flawlessly and I am very impressed with the speed and smoothness...

Thanks to all for some really good advice. I will use shielded wire and twisted pairs to block electronic noise. I am not using a breakout board but wiring the Gecko 320s directly per the wiring...

I am ready to begin soldering the wiring in my Industrial Hobbies CNC Control Enclosure and want to minimize electronic noise. Should (grounded) shielded wire be use to connect the DB25 connector...

The tower/base joint is 185mm long and the bolts are 16mm in diameter and from bolted joint theory, the optimum number of bolts for this joint is 4 bolts on each side of the tower to achieve maximum...

Because of the paucity of bolts clamping the tower to the base, the first issue for me is the stiffness of the joint between the tower and base. The central bolt will increase joint stiffness for the...

As an engineer by training, I chose to follow the tradition of filling machinery bases with polymer concrete as it makes good sense to me from a strength and vibration dampening point of view. I do...

There are several polymer concrete formulas available on the Internet for use in filling mill bases and towers. I substituted crushed granite for about half of the gravel aggregate. I bought aquarium...

Below are some more photos of the base and my polymer concrete fill. I was primarily interested in increasing stiffness with vibration dampening as a secondary benefit. The tubes for the studs and...

There are several web sites showing the reinforcement of mill bases and towers with polymer concrete. What is not generally shared is that aggregate based concretes are at their best when used in...

To my surprise, all the bearings in my mill head gearbox were shielded on both sides and thus were not exposed to the particle contaminated brown goo. I would have thought that the bearings would...

Brown goo removed. I washed down the milling head gearbox with lots of brake cleaner and then a thorough washing with soapy high pressure water. I used dish washing soap and it came out very clean. I...

Thanks all for the responses.

I checked the brown goo with a strong magnet and it is filled with very fine iron particles. I'll now disassemble the gearbox and do a through cleaning. Those fine...

Before turning on my Industrial Hobbies Mill which is in the last stages of being converted to CNC, I decided to open the mill head to check for grit/dirt in the oil. When I opened the mill head, it...
