Re: Noisy spindle

Update on my spindle bearing noise, with advice from Steve at Denfords I have now changed the main bearings and after the first run it seems to be nice and quiet. It took a week of careful work, made a few special tools and pondering how tight the bearing tension nut should be , as it will take a fe...

Noisy spindle

I am in need of a little advice. My vmc 1300 developes a clicking noise from the spindle area as the head heats up on a long job. When it's cooled down its smooth again. Is this a serious fault? I can't see a grease point anywhere, bearings and belt are hidden inside the castings. Are they tapered b...

tomorrow i will select the 100- 200v setting.

vmc1300 avf mode

I have a VMC 1300 with a melted tachogenerator on the SEM motor. (MT30U4-36)
Is it an easy job to run it in AVF mode?
I am a bit disappointed the thing only lasted 2 years light duty before blowing up. The machine was new in 2009 but not used until i bought it 2013.

Re: M0 in VR Milling 5

Did the M00 & M01 issue get resolved?
I am having trouble with it failing to continue, I click the green play button but it just halts.
This is in V5 5.53 running a vmc 1300.
Program has no tool changes.
