That's a shame but probably a symptom of the age of the unit. I would make sure everything is seated firmly and give the cables a wiggle. Other than that it is probably time to cut your losses and get a new console. Machine DRO offer adapter cables for Mitutoyo scales, to connect into current products. They do recommend speaking to them for compatibility.

Ah well, all this swapping of plugs and amplifiers has resulted in the one that WAS working, now isn't!


That really clarifies things.

The 'one' what?

Ian P

I thought that it was obvious; the display that was working now isn't. In other words both displays do not move when handles are turned.

If you want to retain your original readout, contact Darren at Goodwin Technology, to see if they could repair it.

Thanks for that Nick I may well give them a call, but first I,m going the check the wires in the armoured cables as I know some of the plastic in other parts of the machine are stiff and brittle and I thought that the problem might lie with broken wires and it's any easy check to make.

I'm in no hurry and I'm not even sure how useful a DRO is on a horizontal mill. ( plus, I'm a miser)

Edit: If all else fails, it might be worth trying here



Mmm ... deja vu

Ha, I did scan through the earlier posts to see if Goodwin had been recommended, but obviously missed that part in your post.

No problem, Nick

It was the ‘No fix, No fee’ offering that first attracted me.

i’ve never had cause to use them, but assume that you have.

Sent a message to M-DRO. I have one of their units on another machine and am very leased with it, otherwise, It's back to modelling because I'm fed up with fiddling!

Thanks to all who tried to help.
