I would avoid buying the above mentioned board. I made that mistake in trying to get away from the parallel port on the cheap. Single parallel(DB25) interface boards can be coupled to a UC100 for...

Try bbman.com, they may have your desired pulley sizes.

Hoss, I am so glad to see that you are still doling out free advice on CNC builds. Whenever I find myself in a build bind I just mutter out "WWHD?". Have a happy Thanksgiving!

It is fair for a software company to charge for updates but not bug fixes. If an issue crops up that was not identified in beta testing then the company ought to stand behind their product and notify...

Hello Marshall,

Welcome to the 0720/0722 build.

Joe

+1 for both above replies. Since this is part of your business I, too, would suggest going with a plug and play machine. The Tormach PCNC1100 is a good machine with a lot of support behind it. It is...

Hi Wayne(enyaw)

How is your build progressing? Have you made a mess with flying chips yet?

Congratulations on the new mill. I really hope to see another CNC conversion using this mill. It is unfortunate that DRO Pros out here in CA dropped the SX4 from their roster of available machines....

Firstly, I thank all who have responded with ideas and suggestions. I have since reviewed the file and tried to implement changes in the cut strategy. The files so generously volunteered will be run...

Thank you for all your help, Rob. While I have owned BCV24 for a few years now I have not really spent much time with it since this is a hobby for me. We all know how life likes to interrupt the...

Hello LeWhite, thank you for your tip on lloking out for double entities and such. All the help I am getting through this thread is very much appreciated.

Thank you very much, EG. Attached to this post is the .zip of the file HDLogo. I did try other things such as varying the font and, in some cases, it did reduce the offeding lines from 32 total lines...

Hello EG,

Below is the full code complete with all the offending lines:

(BEGIN PREDATOR NC HEADER)
(MACH_FILE=3AXVMILL_MM.MCH)
(MTOOL T1 S1 D.5 H127. DIAM_OFFSET 1 = .25)
(SBOX X0. Y0....

A little background:

I am running BobCAD V24(BCV24) with the latest available updates. I have been trying to do some rudimentary engraving but BCV24 keeps spitting out code that errors out in...

I am truly sorry that you received items that were damaged. Having dealt with Chai Guixian throughout the conversion of my G0720 mill, I have only good things to say about the man.

While modifying...

It is so nice to see that appreciation for this mill as a CNC candidate is growing. Yes, it is expensive to acquire at $ 3,295 from Grizzly or $ 2,995 form DRO Pros but having a tapping feature gives...

Hi Doc,

Sorry to hear of your inverter woes. Thankfully, someone else is carrying the Sieg SX4 here in the US(Milling Machines) and at $ 300.00 less than Grizzly. Support from Grizzly is almost...

Few have gone down the road that leads to a CNC'd G0720/R/ SX4. I am truly glad that you are well on the way to completion. Only one other machine, an SX4, have I seen operating under complete CNC...

Mine died as well. It was a G0720 and it had been in sporadic use for two years when the board died. My mill was already out of warranty so I had to shell out $ 400+ for a replacement. I did try to...

It has been quite some time since someone added to this thread. I may be delaying the inevitable switch to closed loop drive systems but it was fun making these dampers. It is hoped that this will...

A few more...

Dug up an old camera and set it for the lowest resolution.

PM me with your email addy, the files are too big for CNCZone. Most of the pictures are from last year but I have cleaned up my mill area recently to give you a better idea of the build. An old...

The last addition to this thread is almost a year old so I may be writing to an empty room. That said, the conversion of my G0720 to CNC has finally been completed. As soon as I figure out how to...

After almost three years of owning my G0720 mill, it is finally automated. Thank you to everyone who provided ideas for this conversion. A special mention has to go to Hoss who, as everyone already...

Hi Jeff, how goes the conversion to CNC? Did you choose direct driven ballscrews or did you opt for toothed pulleys and belts? I am fairly sure that you ran in to the same problems which are plaguing...

You are right to be concerned about acceleration. However it is of utmost concern only if you want your motors to go from zero to max rpm in an instant. With that goal in mind you may be sorely...

Hi,

Glad to hear that someone else decided on the G0720 series mill. There are only two other G0720 mills being converted to CNC on this site. One belongs to Jeff(Velocirex) and the other is mine....

Hello MillingMan

Your location says "Surrey"; is this Surrey in England? Or is this a namesake city in New England?

Either way, beware of companies requiring money transfers as you may end up...

Hi gzm.pepe, I ran into this problem with my own tests and what I found was that my pin assignments in Mach3 were wrong. Not sure this is your problem but it may be worth investigating.
