Have not been on the zone for a while, but there are some good reference materials floating around on the zone such as linear power supply tutorial, gecko has a good info paper on drives and check...

Alan,
I did find my previous threads concerning automated threading and spindle sync pulses.
One in on the 9X20 Harbor freight and the other is the "Lathemaster 9 X 30 CNC adventure" if you look at...

Alan,
Look at post #40, #41 (PDFattachment on spindle syncs), #47

Alan,
Here is the thread that I posted documenting the method that I used to sync the spindle for threading. I also did a 9 X 30 lathemaster using the same type of set up.

I also try to fing...

Alan,

I cnc'ed two lathes a couple of years back and added a simple spindle sync circuit and gave pretty good detail of how I did it. I'll see if I can find the post and add a comment to bring...

John,
I am currently working on a solar tracking program to use stepper motors to track the sun and would eventially maybe tinker with the idea of trying to generate a little electricity using a...

John

Very nice work!!

Ron

What was the problem and the solution?

Ron

Just stumbled onto this thread, and I too am investigating using visual basic express 2008 to control stepper motors via inpout.dll and the printer port and am also in the beginning stages of coming...

Chris,
The WD40 is good for Water Displacement which is what the "WD" stands for, but it will evaporate and leave your surfaces dry and void of oil. I would be careful not to spray your lead screws...

Looks good! What did you use for the piston and cyclinder?

Ron

I've been looking at the mill myself, but having not really seen it upclose, I can't comment on the quality. It has a good work envolope (not as large as a IH), but for hobby work, not bad and a...

MadCad,
Sounds like you have the plan down. The board has the breakout board function built in to it and you will only need to cable up the motors to it. I used one on a lathe that I converted a...

Wade what setup do you have for your 3450 rpm?

Thanks,

Ron

Any links to info on the New Gecko 540 board?

Thanks,

Ron

Doug,
I use an edge finder and establish x & y (say the corner of the vise or an jig plate) and then you can set your Z using a thickness block or a feeler guage ( I now use a thin strip of typing...

Where are you located?

Ron

Guys,

What is being used for (percission for repeatability) homing switches? Are inductive proximity switches the way to go or do the micro switches have good repeatability?

What kind of...

Sounds like a good project, I think that I would use mach 2 (or 3) and set up two different configuration files; one to drive the spindle z maybe for drilling and the knee zee when doing typical...

Bill,
Tell me about that power drawbar, did you design your own or did you order plans? Seems like Bob Warfield made one from plans from someone. (Thinking of Bob, I haven't heard anything from...

rene,
Usually you would fine you larger motors on the X & Y axis, because they are moving more mass, and generally you want higher rapids (moves between actual cuts), where as in the Z axis you are...

This is certainly an option, do you have an bridgeport already or are you going to get an import. It sounds like Cardinal may build controller for CNC bridgeports where the controller has died (I'm...

Skipper,

By the way, I see some of the guys using these mills and they turn out some pretty good work. You just have to plan ahead as far as your Z-axis, just so you don't have to reposition the...

Skipper,

Just went to the Keling website, If I went that route, I would substitute the KL-201-24 24V/8.3A power supply with the higher voltage KL-320-36 (36 V/ 8.8 Amp) power supply.

The...

Squale,

Someone correct me if I am wrong, but I just went to the SW website and the Trak mills look to be imported BP clones. You can get a cnc'ed one for around $16 K. Might be good units, but...

Skipper,

It’s a fair question, and I feel comfortable giving you an answer. Making the assumption that ball screws and ball nuts are used, and that the stepper motors are driven with bipolar...

Kevin,
Just tried to send it again, hope it worked.

Ron

I am not sure of what the cardinal engineering controller is. If there is a web site link, I'll be glad to look at it.

A lot of guys here will tend to build their own controller which is...

Kevin,
I had to send the plaque Patent info via your email from your web page. Let me know that you received it ok. Could not post .tif files here. Had an idea about a new twist to the patent...

salukikey,

I hold three patents for myself and have filed and received another patent for a friend. What is seen with your first link is actually the out side cover for the issued patent.
