Those collets are a perfect fit. They don't leave any marks. They do require a shorter bolt/drawbar, nothing else. The down side is that you can't change tool without re-setting the z axis but for extra clearance they are really good. They don't come in too many sizes either. I have a 6, 8 and 10mm ...

I don't use a drawbar, just a bolt as I don't have a tool changer. I also just bought some collets that go straight into the BT30 taper. At the moment I have no way to hold the spindle to tighten the bolt but that would give a extra 50 mm or so height. Here is a link for you. ￡4.73 | 7:24 NT30 tappe...

I had backlash in X too, although a lot more than you at 0.4 mm. I discovered that the ball nut mounting was very poorly executed. They use a mounting plate that screws onto the ball nut. So far so good. When the plate is tight on the nut the ball recirculating tube has to point anywhere but down or...

This is the replacement battery I fitted. https://www.ebay.co.uk/itm/VARTA-55615602940-BATTERY-PCB-MOUNT-2-4V-/371194933327?mkcid=16&mkevt=1&_trksid=p2349624.m46890.l6249&mkrid=710-127635-2958-0 My board is not corroded. It is in pristine condition and the battery had not leaked over it. However, re...

I use this vice. https://www.rdgtools.co.uk/acatalog/75m ... ml#SID=354
I'm very impressed by the quality. Had it a couple of years. I don't use the quick change tool holder but ER32 BT30 holders. The combination of the 2 helps with height.

So, every now and then, for no reason that I can see, everything works fine. Switch machine and computer off and on and the problem is back. I assume that this little battery has a function, perhaps to keep the mint file alive? Anyway, I decided to change it. After I got it running again with the ne...

I realised the serial cable isn't standard yesterday but I had the plugs apart and checked the individual wires for resistance. All checks out. Same for the 25 to 9 pin

Hi Martin,
The 7 segment display does not go out when it fails. Could the little 2.4V battery cause problems. It had some sort of residue on it. Crystals of some sort. It may have leaked. Nothing went on the 9 pin plug below, I checked that and it clean as a whistle.

I have the same issue but I don't have a spare Denstep board. Any idea where I can get one from?

O also get this when the fault happens. And then this when I click ok.

There is a component labeled SGR which has a LED and that isn't illuminated. Should it be?

Hi Steve, Thank you for your reply. I'm not very familiar with the terminology. I'm more of a user than a repairer. I took a picture. The 7 segment display is on. Is that board the Denstep? The fault is now intermittent. Switched the machine on this morning and after it told me the mint version was...

Hi, I have a Novamill without the Feed and Speed override knobs fitted to the machine. I use VR Milling version 2.16 and in Auto mode the I can't alter Feed and Speed at all. They are set at 75% and 85% respectively. Is there a way to get the sliders or F5 to F8 buttons working? Alternatively how ca...

Hi, when I call a M98 in VR Milling Version 2.16 the program pauses and I need to press the start button again. Same thing when a M99 is called. Is there a way to make the program run all the way through? Any help would be appreciated.
