My VMC1300 Pro has just developed the same "ticking" noise from the spindle after it's been in use enough to warm up. I fear I have to go through the bearing replacement process too. I have the spindle section drawing posted in the drawbar thread, so I can see generally what's required. I have a lat...

Writing up the conclusion of this problem in case others experience. It seems contacts on the door electromagnetic lock switch intermittently fail to close, causing the spindle not to turn. The door lock (Bernstein on my machine) has confirmation contacts (31 32, see circuit diagrams in this forum) ...

Belated update on lubrication of axis screws rotary bearings. I used a syringe on 3 bearings, the X right you can see in the pictures is sealed so I left it alone.

My VMC 1300 Pro has occasionally failed to turn the spindle on program start. The machine traverses XYZ with the spindle not rotating. Usually, homing and trying again resolves the problem. The issue seems to be getting worse – happening more frequently and requiring machine power down/up to get the...

Just a note to say I serviced my VMC 1300 Pro drawbar using the info supplied and it cured by lose tooling problems. I made a spanner from an old imperial socket to turn the nuts. When replacing the drawbar, not the orientation of the flat on the bar and the indent in the spindle so you can slide th...

Steve, What's the best way to remove the drawbar rocker VMC/073 to get access to the drawbar locknuts? It looks like the rocker pivot has a sort of clip retainer - can I just ping this off?

Thanks Steve. So there is one "axis rotary bearing" per axis and it's an unshielded ball bearing at the far end of the mount from each axis motor. That should be a fun task to access those with a syringe!

In the VMC 1300 Pro CNC Milling Machine User’s Manual Page 41 12: Lubrication Chart says: Machine Ballscrews with grease gun Every 3 Months Machine Slideways Every 6 Months ... Axis Bearings Apply by Syringe Every 12 Months Then there are photos pointing out for example, Four lubrication points for ...

I always forget to turn my step increment down to .05 from .1 when edge finding
Can I set this 0.05 value as a default somewhere?

I did the adjustments per Steve's posts and added the heater on lowest setting and now can home and toolchange without issue. I'm happy the G28 goes to top of Z before homing X and Y. Thanks both

Thanks, will set per your default and lower the speed next week and see what happens

I am up to date with V5_68

My drives are set:
1 ON
2 ON
3 OFF
4 OFF
5 OFF
6 ON
7 OFF
8 ON
Which the datasheet tells me is 5.7 Peak, 4.1 RMS, so one setting softer than your default listing

Thanks for that info Steve, just what I need I think. I have just done a full greasing on all the ballscrews, including the really tricky to get at ones! I did disconnect the Z brake, noting the axis will fall under it's own weight. I then tested the same rapid homing without any issues. I reattache...

I started a thread in VR Milling, thinking I had a software problem, but further diagnosis shows a problem with my 1300 Pro Z axis brake. The symptoms are for commands G91 G28 X0 Y0 Z50 or M0 T06 the machine starts to go up in Z, but makes a really bad noise and Z stops moving without going home. Vi...

Having spent some time over the holiday, I can confirm the problem is with the Z axis brake, so not a software issue. I suspect the Z brake solenoid is starved of power when the 3 axis drives all start up on rapid, and the solenoid lets go and the brake springs on. I'll start a new thread in the VMC...

I'm now working on the theory that the noise I hear is due to the Z Axis brake still being on when the machine tries to home. I am experiencing this problem when I try to do a toolchange without a prior G28 too. I can see the Z Axis brake state on the Mint i/o debug screen as Output 15, so I'm going...

I'm learning to program with VR Milling V5 and driving my VMC 1300. I've got to the point where I want to make a manual toolchange during a program. I'm mostly using "G and M Programming for CNC Milling Machines" as my reference. When I complete the moves with first tool, I programmed the toolchange...

I'm about to service my VMC 1300, and access to the rear grease points is a challenge! Removing the guard will give me a bit more room above the spine when I lean in to the cabinet. Any tips? I'm going to source a grease gun too, any experience/tips will be appreciated. The small Hiwin nipples appea...

It def helps to write down the thinking to work out the answer!

Doh!
Fixed the problem. I resorted to saving a machine file, unzipping it and reading the MNT file looking for clues.
Machine cover interlock switch - I disabled it ages ago when I first got the machine, and forgot - saw the MachineSafe clue in the code.
Anyway, sorted, lesson learned
