Hi All,

I have my CNC maching up and running, using Mach 3 software. Generally when I cut things I am in the shop when is completes and I go over an shut the dust collector, router and vacuum...

I am using MDF for my spoil board that I have fly cut both sides. I have not sealed the edges of it and plan to do that for the next round of testing. I have also heard different types of MDF will...

I have done some initial testing doing that, blocking off parts of the spoilboard not being used.
I was looking at this from a techinical standpoint...ie how many inches of Hg do you generally want...

I have a built a vacuum table for my CNC router that is 40"x40". Initially I have used a 1 HP rotary vane pump as my vac source. I was not sure if it was large enough to adequately provide enough...

I suppose it could be....the mfg calls it a NEMA 34 motor though.

I recently ordered a NEMA 34 stepper motor and found the shaft diameter was 0.62" diameter. I was under the impression all NEMA 34 motors had a 0.50" diameter shaft.

Just curious if the NEMA spec...

Hi All,

I am looking for suggestions on improving how I hold pieces down when I preform operations where I cut through the material.

I cut out a lot of 4" diameter circles 1/2" thick and...

Thanks for the reply, I was most likely going to go with the second option and tighten it till it "feels" good. Which brings me to my second question...what type of wrench to use...

I have a...

I am using thompson ball screw, ball nut and end block for both my X and Y axis.

Recently connected the motors and have everything moving properly.

Does anyone know the procedure for setting...

Thanks again for the suggestion. I found the tutorials VERY helpful. I now have the motors spinning and running good.

Thanks again! :cheers:

Thank you for the suggestions. I will watch the tutorials.

I had heard that Lazy CAM was difficult to use, I will take a look at Vetric.

Thanks again

I have recently completed my cnc router table and am at the point I want to try testing each axis and to possibly run a simple program in Mach 3.

I have downloaded the trial version of Mach 3, but...

Hi Sol,

I will search around for the rebuilding article on these and see if I can't get them reloaded properly. Its good to know that nothing is damaged, just sounds like I may have started off...

Sol,

Thank you for your response and use of the upload site.

I am using a Thompson 1" round ball nut with external return tubes. Picture link is below

Posting a picture of my setup.

Once again I am sure I am overlooking the obvious, but appreciate any input.
THanks

Hi All,

I have what is most likely a dumb question, but here goes....

Building a CNC router and when I installed the ball nut for the Y axis and rotated it along the ballscrew, several of the...

Hi Guys,

Thanks for the suggestions, I will take a look at both of them.

Hi All,

I am in the process of building a CNC router and wish to get a jump on learning a bit about the software I will be using. I plan to use Mach 3 for running the G code, however I am looking...

I purchased a Thomposon Ballscrew End block from McMaster Carr their part number 60755K15. This is for a 1" ballscrew. I am looking for a spec sheet to this end block to give to a machinist who is...

Thanks for the input. I have looked at Roton and contacted them, they do not provide machining services. I am finding most places that sell them do not provide machinig services. I will most likely...

Neil,

Thanks for the input, I will give Reid a call. I had been ordering most of my supplies from McMaster, they may offer the service too, but I have not asked them.

Thanks again for the...

I would like to better understand how to go about specifying machining requirements to a machinist for my ball screws. I will be purchasing my ball screws new and need to have both the end blocks and...

At this point I just have the table base drawn up in Autocad, I am working on the gantry drawings, but will base them on Shop Sabres 4x4 table design. http://www.shopsabre.net/

It seems to be a...

Thanks,

The main sections are 3" 11GA tube and the smaller cross pieces are 2" tube.

I am sometimes guilty of "Battleship Engineering" but I think in the end it willmake for a very rigid base...

Hi All,

I have made the first jump into building my own CNC router table, see attached photo. Just finished the base this week. I based it in part on Shop Sabre's table and will probably follow...

Hi,

I am looking to purchase a 4x4 CNC router table. I am looking for any input on different brands or advice you may have to offer.

I will primarily be cutting 3/4" hardwood. I have never...

Bob,

Thanks for the input, I appreciate it. I keep bouncing back and fourth about either building one or purchasing my first one to get my feet wet on cnc routers.

I will keep reading the...

I am still collecting more information before jumping in to building a CNC router, and am looking for some advice on stepper motor ratings.

I plan to build a 3'x3' table, construction using...

Gerry,

Thank you for the information, I will go the 4 axis route.

Thanks again

Kevin

I am considering building my first CNC machine and have seen several designs that use 2 motors on the X Axis. I would like to use this design approach. My question is are these two motors generally...
