[St...] Posted June 5, 2019 Share Posted June 5, 2019 I've just started a new job and have noticed that the machine they have (Contura RDS) makes a faint humming noise when the Z axis is extended out nearer the higher limit of travel. I've run other Conturas (G2s) and never noticed this before. Does anyone have any insight ?

[Ja...] Posted June 5, 2019 Share Posted June 5, 2019 It could be the counterweight needs adjustment (happened to our MMZ-B). Does your company have a service contract with Zeiss?

[No...] Posted June 6, 2019 Share Posted June 6, 2019 I don't know about the newer Conturas, but our old one (one of the first) doesn't have a counterweight. The Z axis is balanced by some kind of pneumatic cylinder. Ours needed a repair or adjustment at this part many years ago, but I don't remember why.

[Me...] Posted June 7, 2019 Share Posted June 7, 2019 We have a brand new Contura RDS XXT. It also hums fairly loud at the top of its travel. Never crashed and just had it calibration.

[St...] Posted June 10, 2019 Author Share Posted June 10, 2019 Okay, Thank you all for the input. I haven't noticed any issues with measurements so I'm going to roll with it for now.
