Have you had a look on youtube. Lots of dro conversions on there. If not your model at least get some idea's.

Steve.

I've just fitted one last week as im now onto the cross slide.

You need to move the black controller back section out 30mm to allow for the scale to fit inside, also if you clip off 10mm each side of the black controller then the head can lift 60mm higher (bonus )

I will sort some pictures later today

On my fairly similar X3 I fixed the bottom bracket to the base of the column, make sure you raise the end of the scale enough so the Y one can pass under it. These are M-DRO scales and covers.

Then at the other end fixed down into the top of the column using one of the existing cover screws

Will take a photo of how the read head is fixed to the mill's head later but yours may need a slightly different fixing due to the swivel head.

Have you got  alink for the SX3 kit as I can't see one listed on their site.

I made my own as was a better instalation as i also fitted the z axis in the column and moved the controller box back 30mm

The machine controller i mean is the big black box on the back of the machine, i moved it by 30mm to allow the scale to be fitted inside, i also modified it to allow the head to travel 50mm higher, i fitted the DRO arm to the top of the controller box on the right hand side, it is ok and at the right height to read it.

i have painted the floor today but will get some pictures tomorrow

Hi Mike,

I cant speak for the SX3 but I fitted my Sieg SX2P mill with a 3 axis set (from ARC) and they came with a variety of brackets and fixings, some of which I modified and used but also made some of my own. I think that is the norm when you get a universal kit, probably different when you have a set made for a specific make and model of machine.

Unless you can find someone or a write up that covers the detail and parts used in fitting a DRO set to the SX3 you may find that you are on your own. Actually its not that difficult to fit a set just takes a bit of sizing up, positioning and either using the supplied fittings or modifying them and/or making your own.

P.S. There you go Martin will probably have all the info you need.

Just on second coat of the garage floor but some quick pictures this morning of position ot the DRO arm, inside the rear column 2 cross beams and a bracket (all inside the black control panel) i moved back the screws on top 30mm to allow for this and i also removed 10mm each side at the top to allow the head to rise 50mm higher !!! Arm top right

top of head screws moved 30mm backTo allow Z scale inside

I have Moved the milling machine back into its final position, picture showing the DRO arm position

I'm impressed by the neatness of your installation, particularly with the mounting in the rear column.

I've just invested in a 3-axis kit for my SX3 from MachineDRO so would like to pick your brains and benefit from your experience if you don't mind. It will be a while before I actually find time for my installation but I'd like to get it clear in my mind how I will go about it. It may be that I should address some questions to MDRO, and that the answers to some will or would be obvious when the rear column cover is removed – but in a restricted space my mill takes a lot of moving so a quick look inside beforehand is not so easy.

An easy starter – you obviously discovered how to cut the magnetic strips to length, please tell.

Is the mounting for the display fixed to the pressed-steel cover, or through it to something more substantial?

On the X-axis you have mounted the scale on the table with the read head fixed, but vice-versa for the Y-axis – with the scale fixed and the head travelling with the saddle. Why have you chosen to do thi?

I'll leave the rest, rather than over-burden you with the whole lot in one installment.

Thanks.

Thanks Martyn – interesting photos and another good looking installation. See that you have gone for fixed Y-axis read head and scale on saddle, but wondered what Mike Donnerstag's reasoning was behind doing it the other way round.

How did you cut the magnetic strip to length?

I still like the neatness of hiding the Z-axis gubbins in the column, but am hoping to pick Mike's brains on that.
