Show"N"Tell ( Your Machines) / Re: Upgrading to linear bearing system advise!!!!!!

Q- Will a 16mm bearing block and 15.875mm aluminum rod work and fit fine?
No. Not at all.

So if i buy a 16mm bearing block and a 16mm steal or aluminum rod would that work/ fit together fine? (buy them separately not as a set )

Show"N"Tell ( Your Machines) / Upgrading to linear bearing system advise!!!!!!

« on: March 25, 2012, 06:44:42 PM »

I am planing on switching to linear bearing system from aluminum angle/ball bearings. I am only planing to convert the y and z axis and the dimentions are about y=30"/z=12" more or less.    

So i am planing on buying the aluminum round rod and bearing block separate. I think i am gonna go with 12mm or 16mm system as they seem to be the cheapest.

this link shows a 12mm aluminum rod and bearing shaft system pre installed very expensive though

These aluminum rod are way cheaper that the other onces that comes in a set. Only different is the supplier only have rod in these dimensions
aluminum rod 9.525mm,12.7mm, 15.875mm,19.05mm, 20.624mm, 22.225mm

bearing blocks 12mm, 15mm, 16mm, 19mm, 20mm, 22mm

So my best bet seems like the 15.875 aluminum round rod and 16mm bearing block (did i got that right)

Q- which one of these above combination would work the best or any other ideas?

have a wonderful day

@Tweakie.CNC no dout about it that the aluminum rail system is very hard to set up, i would love to use a the leanear ball bearing rail system if i get a good deal or birthday gift . But for now its seems that i had to get the best out of what i got. here is some more pics....
i have been playing around with engraving and profiling using cambam here are some of the result i have got so far.

I been about couple of months that i have been working on this machine. The plans are taken form the buildyourcnc.com book design free pdf. The linear system that the machine used is the aluminum angle w/t ball bearing and the linear driver is a 4' all threaded lead screw. The wood that i have used is MDF. Basically i follow the entire book from step to step expect some stuff. I was only allowed to put only 4 pic,
i didn't had any good wood cutting system so the pieces cut were not very persice which led to machine being not so great, but still very pleased "The problem that i facing right now is if i tighten the screws too much the gantry gets stiff but hard to move. If i loosen them then the gantry get wobbly thus still pretty precise cuts but no big stuff".

« on: February 06, 2012, 06:40:38 PM »

I got it to work!!!!

Here is hw you do it


1. download the file that has been sent to you by mach3 (don't download twice as it would rename the file so if you use the renamed file it will not work)
2. put it on the usb if need to trasfer to other machine
3. CLose mach3 (if had it open prior)
4. Go to directory C:/mach3 (or if you changed it to something else like d:/mach3 watever )
5. COpy paste mach3 file in to the c:/mach3 directory
6. close the directory window
7. Start mach3
8. start maching.......


Things to look for
1. don't rename the file
2. close mach3 while doing the copy paste (just a assumtion that i might mess things up)
3. don't rush pay attention  (kind of wat i did)
4. make sure the file name stays Mach1Lic

what to do if all hell fails
1. post a brief description of your problem (with screen shot of the file in the c mach3 directory)
2. send a email to scottn@machsupport.com (if all hell fails )
Happy machining

I am using windows XP,
Ok so do i put the file while the mach3 is close or while it is open     (may be that could have wat cause the problem in first place)

THX i will try that......... (last time uninstall i didn't deleted the directory)

So i bought the mach3 license installed it, and it did not work!!!!!!
JUst like it said in the email i put the license file into the c:/mach3 folder
And it still says demo and only go up to 500 lines (i also restart pc and even reinstalled Lockdown:Mach3 R3.043.022)
I feel so  
wat am i missing.....
