How to attatch 2040 extrusion to linear rail bushing block

November 9, 2017, 5:31 pm

Hello,
I am using "supported linear shafts" and i need to attach the bearing blocks to a 2040 T slot extrusion... the problem is... the bearing block accepts screws TOWARD it... and the 2040 extrusion also only accepts screws TOWARD it... i do not have room to slide a mounting plate between them without misaligning my machine, the only way i can imagine is to drill holes in the extrusion and screw right through it...

this raises a new question... HAS ANYONE EVER INVENTED SOME SORT OF JIG FOR DRILLING SUCH HOLES FOR A BEARING BLOCK... im actually kind of sick of fumbling around trying to drill 4 holes exactly perfect for these things or really any such block Ive had the same problem with acme and ball screw nut housings... its kind of the main problem in building CNCs period in my opinion... (outside of the fact that the bearings for supporting acme screws and ball screws are shorter than height of nema motor shafts which literally makes about 0% + 0% = 0% sense but thats a discussion for another time)

much appreciated
-Joe

Newbie Advice re Milling Aluminium

Hi All,

I have a 6040 CNC machine with an 800W watercooled brushless motor. Using Artcam Express 2013, Mach3 and a UC100 motion controller. With this setup, I can quite happily design and mill 2D shapes, usually in MDF. I have the 6040 housed inside a perspex & MDF enclosure with a dust extractor nozzle close to the workpiece, connected to my vacuum cleaner.

I need now to be able to mill 2D and 3D shapes in aluminium. I have the G-Code and have milled two test pieces out of MDF and an old offcut of kitchen worksurface. The 2D shapes will be milled out of 6mm aluminium plate and the 3D shapes, out of 40mm aluminium block. I purchased two good quality end mills, one is a 6mm 2 flute, the other a 3mm 2 flute. I have used the various calculators to determine the correct spindle speed and feed rate. They all give fairly comparable results so I guess they must be correct. However, when I set the 6040 going, she seems to be rushing too fast and the surface finish is poor.

I have watch many YouTube videos of people happily milling 3D shapes where the 6040 seems quite happy. My first attempt is shown in the attached photo. I did use a cutting oil sprayed onto the end mill from an aerosol can. To what should I set the spindle speed, feed rate, step down, etc, to correctly mill this 3D block? Is slot milling a sensible idea?

Any help gratefully received.

Regards

Gary

Motor VFD Power matching

I need to replace my 5.5KW VFD for a different unit.
I'm offered a 7.5KW VFD for the same price as the 5.5KW VFD.
The motor is 5.5KW. Can the 7.5KW VFD be used with my 5.5KW motor? Or is it better to replace with a matching unit?

I have built a three axis cnc router with 1” lead screws and pillow block bearings . The machine is using nema 23 stepper motors and I purchased a tb6600 4 axis controller . The problem I’m having is I can not get any movement at all . I have tested voltage from the 2 parallel ports I have in pc . I have 3.4 volts onboard and 5.3 volts on pci port . I am using a 36volt switching power supply and mach3 . I have checked voltages on tb6600 board and can’t find the problem . I have attached pictures of my build . Any help would be appreciated!

Hi,
I was wondering if it is possible to load IGF into a machine that does not have it? and is it available? I use it in my LB-15 and really like it. Both machines have OSP5000 controls.

I called Okuma and he was going to check but I never heard back.


Thanks,

Pat.

New Machine Build TORMACH 1100

I need some help! I just purchased the Tormach 1100 Part Maker Package with full enclosure, ATC, RapidTurn, Tilting 4th axis,..........

So far here have been my issues....

1. The controller was bad (would not start up, Tormach sent a new one)
2. After assembling the stand, mill, enclosure, putting on the ATC (not dialed in as of yet) I lost all of the lights and power to my drivers.
3. Tormach sent pictures of the correct wiring inside the E-Stop relocation switch (lights and power are now back on) but, when the controller fires up and I reset the E-Stop and hit the start button, I can see on the controller that the X, and Y axis are active and noted to the left on the screen and lit up on the right with the green bubbles, but the Z axis is not showing on either side and I cannot hit the reset button in PathPilot without getting an error code "Command cannot be executed unless machine is powered on and the control software is out of RESET". The machine is on all driver's are lit the added circuit board led's (red and yellow) the red is lit but the yellow is off. And I cannot move the X,Y,Z with the keyboard or shuttle.


Any thoughts?

Also I do not have a Enclosure door switch and the box is not checked in PathPilot.

Hi folks I'm machining a part but require a 12mm end mill to machine a 30 degree angle using the y and z plane. Is it possible to do this using the angle feature i.e. for x and z plane

G0 x50 z2
G1,A180 r2 f0.2
,A110 x75
G0 x200 z200 m5

It saves you working out the start and end points of the radius in the above example.

Thanks in advance

Help converting stl file if possible

November 10, 2017, 10:04 am

Hello, I am not new to this forum but cannot remember my old credentials...lol so now I am MP40cal.

Anyway, I bought an expensive $109 obj file of a vehicle. I have converted it to an stl file and am hoping I can somehow wood cnc machine from it. I have VCarve Pro and a number of CAM programs. My problem is when I orient the file to the view I want to machine the file does not get rid of the parts you cannot see. I only want to machine the visible portion of the file. When I import the stl into VCarcve Pro it imports the whole car, so when I look at it from an angle view and drop it into my material the front of the car still protrudes about an inch and a half of the material.

I know it may be hard to visualize and I may not be explaining very good. I only want to import or cut just the visible portion of the file.

I have tried to import or attach the picture I am trying to cut.
Hope it works,

Thanks everyone. I am in a time crunch and am trying to get this done for my employer.

Need Help! Mazak M2 Tool Path Erratic

November 10, 2017, 10:55 am

My Mazak VQC 20/40 running Mazatrol M2 has been stopping in the middle of a program for no obvious reason. No alarms. For a while it would work OK in the morning, but after about 2-3hrs would come to a halt with the spindle still turning. It looked as if it was waiting for the next line of commands, with the 'Busy' light on. When I tried to run "Trace" this showed the same result by hanging indefinitely, but "Shape" always works. If I loaded a very simple program with a single short milling cut then everything works well, no stopping, runs all day, "Trace/Tool Path" all working. The programs that do not work are for only a few drilled and tapped holes, ie nothing long and complicated

I decided that this looked like a deteriorating component on a board performing arithmetic processing, so I bought a complete set of boards and swapped them one by one. This made no difference. I focused on boards FX-01 FX-84, FX-84-1, FX-15/25, FX-27, checked parameters (I used the original set that came with the machine), disconnected batteries and reinstalled everything from scratch. Now it will not run in the morning like it used to, but still no alarms and the simple program runs perfectly at all times of the day. In the "Graphics" mode the "Trace/Tool Path" works for the simple program only, "Shape" still works on every program. So I now have a machine that will only do a short milling cut!

I have run out of ideas. Can anyone suggest something I have not tried?

Looking for (second hand) Planet CNC MK2-9 controller

Hello everyone.

For some years I've been using the Planet CNC MK2/9 controller board (see attached pic) with much fun. Unfortunately some input-channels on the controller stopped working. Probably some I/O chip is damaged. A few months back I had the same problem, sent the controller to Planet CNC and they were able to repair it. But maybe because I made the same mistake (again... :nono: ) the I/O could be damaged again. Planet CNC has stopped supporting this one, and are most happy to sell me the new MK3. Now I'm looking for one (or more) replacement MK2-9 controller board(s).
PlanetCNC Mk2-9.jpg
So the question:
Is there anyone out there who still has a MK2-9 controller lying around, fully functional, with license and serialnumber? Price and logistics are negotiable. It would help me a lot, since my machine is completely build around this type of controller.

Thanks y'all.
