I have access to both a CNC Sherline mill and lathe. I have pretty much got everything working on the mill and I can import a drawing from AutoCAD into Mastercam Mill generate the post and it runs...

Have you checked out Desk Engrave? It is a free program that converts TTF fonts to either GCode or a DXF file. It can also do polar layouts. Download it here The home page can be found here

Here is a link some resistor calculation software for stepper motors. This is the same one from balsaman's post a whlie back but the place that used to host if does not any more. ...

The computer will output pulses regardless of anything connected to the paralell port. So, if Mach works now, it will work with geckos connected. Also the type of drive will not effect Mach.

Your conversion looks good so far. Where are you geting your screws from? Will you be machineing the ends yourself?

I have had this problem with my motors before. Go into Config>Motor Tuning and bring the velocity setting way down so the slider is just above 0. Accel should be set low also. Save these settings...

Hi Mike,

I Dont think that it would be a good idea to out both the encoder and servo connection in one connector. The encoder signal may be interfered with due to the servo signals. Shielding...

Hi Mike

I'm not sure if you are still in need of a reply but seeing as no one else has responded, I might as well share what I am planing to do with my contol box. First, I would suggest a main...

Hi Darren,

It looks like those servos are the same "cheap servos" that can be found here. The ideal power supply for those is 36V @ 20 to 25A. You could construct a power supply fairly simply...

I'm in the process of trying to find a suitable servo motor to use in a Sieg X2 conversion. Most of the conversions I have seen use stepper motors in the 300 Oz/In range. I'm looking to use servo...

Would these motors be any good as servo motors in a mini-mill application or are they under powered?

When the computer first boots, look for some instructions to enter the BIOS. It may be something like Delete, F10, or F1. In the BIOS, look for the boot order and change it to boot of the CD Drive....

Yes, I agree. That was the same reaction I had when I first learned about home built CNC machines. I didn't know what 95% of the CNC related stuff was. Things like backlash, ball screws, and...

What type of bearing/bearing assembley is commonly used on routers with ballscrews? I have read some threads about thrust bearings. What are these and where can I get these?

Thanks

They have a nominal voltage rating of 60V and a maximum continuous current rating of 8.9A.

If I was using 3 servo motors that at stall draw 44 amps each with Gecko 320's which allow a maximum current of 20 amps with fuses to prevent to much power to the motors, would I need a power supply...

Is any one familiar with Nook Industries's ball screw bearing supports? They call them EZZE-MOUNTs. If I were to use those on a router, with direct drive, would I need just 1 on the side opposing...

How about ballscrews from Roton. Has any one used these before? How do they preform? http://roton.com/web/balls.jsp

I was wondering how much accuracy is possible with rolled 5/8" ballscrews? Could they be accurate to .005"?

Paul, are those ball nuts and screws from Roton. Are the screws 5/8"?

Thanks

Oh Yeah,
I am planning on using a direct drive

Hello

I am planning on converting a Homier mini mill and I was wondering what size stepper motors I should use. I am planning on using the Xylotex driver board. Also, if I were to convert it to...

Hi,

Does any one know how many amps a grizzly mini mill draws running at top speed? Also, could a solid state relay be used to remotely turn on and off the spindle motor on one of these mills?
